1 HP ZCentral Remote Boost overview
HP ZCentral Remote Boost brings added security, performance, mobility, and collaboration to your workstation deployment. With HP ZCentral Remote Boost, you can use a lower-powered desktop, notebook, or thin client to remotely connect to a powerful workstation and use your graphics-intensive workstation programs wherever you go. Your programs run natively on the remote workstation and take full advantage of its graphics resources. The desktop of the remote workstation is transmitted over a standard network to your local computer using advanced image compression technology specifically designed for digital imagery, text, and high frame rate video applications. The following image and table demonstrate a typical HP ZCentral Remote Boost deployment.

Table 1-1 HP ZCentral Remote Boost deployment components

Item

Description

1

The sender is typically a high-performance workstation, virtual workstation, blade, or server that hosts your software. HP

ZCentral Remote Boost Sender is installed on the sender and transmits graphics, audio, and USB data to the receiver. The

sender receives input and USB data from the receiver.

NOTE: A monitor does not necessarily have to be connected to the sender.

2

The receiver is typically a desktop, notebook, tablet, or thin client with HP ZCentral Remote Boost Receiver installed. You

establish the Remote Boost connection from the receiver side. The desktop of the sender is displayed inside the HP

ZCentral Remote Boost Receiver window on the receiver, and Remote Boost Receiver transmits input to the sender so

that you can interact with your programs remotely.

3

A TCP/IP network serves as the communication link between the sender and the receiver.

IMPORTANT: The sender and receiver must be on the same network for a Remote Boost connection to be established between them.

1

NOTE: HP ZCentral Remote Boost software and documentation might also refer to the sender and the receiver as the remote computer and the local computer respectively. HP ZCentral Remote Boost system requirements, such as hardware and operating system support, are not discussed in this document. Some HP ZCentral Remote Boost features might have additional system requirements. System requirements are described in the QuickSpecs (see Finding more information on page 4).

Interoperability between different versions of HP ZCentral Remote Boost
Interoperability is supported between different versions of HP ZCentral Remote Boost Sender and HP ZCentral Remote Boost Receiver only if they have the same primary version number.

Table 1-3 HP ZCentral Remote Boost version number items and their descriptions

Item

Description

1

Primary version number: A primary release typically contains upgrades and changes significant enough that

interoperability with previous primary releases is not guaranteed by HP. For example, a connection between different

primary releases of HP ZCentral Remote Boost Sender and HP ZCentral Remote Boost Receiver might not function at an

acceptable quality, or at all.

2

Minor version number: When this number is zero, it represents a minor release, which typically introduces new features or

enhances existing functionality, as well as including changes from any previous patch releases. A connection between

different minor releases (but the same primary release) of HP ZCentral Remote Boost Sender and HP ZCentral Remote

Boost Receiver should function at an acceptable level of quality.

3

Patch version number: When this number is zero, it represents a patch release, which is typically only for fixing major

security issues or defects. A connection between different patch releases (but the same primary release) of HP ZCentral

Remote Boost Sender and HP ZCentral Remote Boost Receiver should function at an acceptable quality.

NOTE: Each release of HP ZCentral Remote Boost is a complete release of the entire product, regardless of which components have changed. NOTE: The version numbering changed between HP Remote Graphics Software (RGS) and HP ZCentral Remote Boost. The last version of RGS is 7.7.x and the first version of Remote Boost is 2020.0.
Software compatibility with HP ZCentral Remote Boost
HP ZCentral Remote Boost works with most software that runs in windowed mode, including those based on OpenGL and Direct X. Some exceptions include:
Interoperability between different versions of HP ZCentral Remote Boost 3

 The installation of HP ZCentral Remote Boost Sender disables video overlay surfaces on the sender. Most OpenGL-based software will adjust to this and still work correctly, but in some cases, the following could happen as a result: ­ Some OpenGL-based software might display incorrectly. ­ Media players that use video overlay surfaces might display incorrectly. If these types of issues occur, likely the software is still trying to use video overlay surfaces even though they are disabled. You can sometimes resolve this issue if the software has an option to disable the use of video overlay surfaces.
NOTICE: HP ZCentral Remote Boost Sender does not support programs in full-screen exclusive mode. This means that HP ZCentral Remote Boost is not suitable for most full-screen games.

HP ZCentral Remote Boost Sender licensing
HP ZCentral Remote Boost Sender is included with HP Z workstations, HP ZBook mobile workstations, and HP VR backpack workstations. A separate license purchase is not required for HP ZCentral Remote Boost Sender on these products. HP ZCentral Remote Boost Sender requires a license if installed on any other computer. Further information can be found in the Licensing Guide (see Finding more information on page 4).
NOTE: An HP ZCentral Remote Boost connection can be established without a license; however, a warning message about the missing license is displayed over the HP ZCentral Remote Boost Receiver window, blocking a significant portion of the Sender desktop. NOTE: HP ZCentral Remote Boost Receiver is a free download for all devices.

2 Getting started
The following procedure is a high-level description of how to get started using HP ZCentral Remote Boost: 1. Install HP ZCentral Remote Boost Sender and HP ZCentral Remote Boost Receiver. 2. Open HP ZCentral Remote Boost Receiver. 3. Start an HP ZCentral Remote Boost session with the sender.
a. On the Home panel of HP ZCentral Remote Boost Receiver, enter the host name or IP address of the sender, and then press the Enter key or select the Connect button.
b. In the HP ZCentral Remote Boost authentication window that appears, enter the credentials of a user account that resides on the sender, and then select OK.
If authentication is successful, the HP ZCentral Remote Boost session starts, and the sender desktop appears inside the HP ZCentral Remote Boost Receiver window that opens on the receiver. NOTE: If the sender desktop was in a locked state when you started the HP ZCentral Remote Boost session, you must unlock the desktop by entering the credentials again, this time into the logon screen on the sender.
5

3 Installation
Follow the installation instructions for your operating system. NOTE: Although RGS has a new name, HP ZCentral Remote Boost, the installation parameter names, folders and executable names have not changed.
Installing HP ZCentral Remote Boost Receiver (Windows)
The installer wizard for the HP ZCentral Remote Boost Receiver allows for both Typical and Custom installations. The Typical installation installs Remote USB and Remote Clipboard. The Typical installation should be suitable for most deployments. The Custom installation type lets you choose whether you want to install certain features, as well as specify proxy settings. You can perform a custom installation on the command line as well. IMPORTANT: Windows administrator privileges are required to perform the installation. NOTE: If the software is already installed, installing a newer version will perform an update. Attempting to install the same version or an older version will cause the installer to exit without making changes to the system. NOTE: During the installation process, the installer creates a log file named rgreceiverInstaller.log in the location specified by the Windows TEMP environment variable.
Performing a custom HP ZCentral Remote Boost Receiver installation using the installer wizard
To perform a custom installation of HP ZCentral Remote Boost Receiver on Windows using the installer wizard: 1. Run ReceiverSetup64.exe, follow the on-screen instructions until you are prompted to choose a
setup type, select Custom, and then select Next. 2. On the Remote USB Configuration page, select the appropriate installation setting for the Remote USB
feature from the following options, and then select Next.  USB devices are Local--Remote USB is not installed on the receiver, and all receiver-side USB
devices always mount to the receiver only, even during an HP ZCentral Remote Boost session.  USB devices are Remote--Remote USB is installed, and all receiver-side USB devices always
mount to the sender only, which means the USB devices are accessible only during an HP ZCentral Remote Boost session. The USB devices cannot mount to the receiver at any time, regardless of the HP ZCentral Remote Boost connection state.  USB devices are Local/Remote--Remote USB is installed, and each USB device has its access set individually to either the receiver or the sender, depending on when the USB device is plugged in to the receiver. ­ If a USB device is plugged in to a USB port on the receiver while HP ZCentral Remote Boost
Receiver is disconnected, the USB device becomes accessible by the receiver only. ­ If a USB device is plugged in to a USB port on the receiver while HP ZCentral Remote Boost
Receiver is connected, the USB device becomes accessible by the sender only.
6 Chapter 3 Installation

You can switch access to a particular device by removing it and then re-inserting it while the HP ZCentral Remote Boost Receiver is in the opposite connection state. NOTE: This setting controls whether Remote USB components are installed. To change this setting after installation, you must uninstall and reinstall HP ZCentral Remote Boost Receiver. If installed, Remote USB can be disabled (and re-enabled) later using HP ZCentral Remote Boost Receiver or the HP ZCentral Remote Boost Receiver Configuration tool. Alternatively, you can override the Remote USB installation setting for individual devices (without a reinstallation) with an advanced option that the installer does not offer (see Configuring the remoting behavior of individual USB devices (Windows only) on page 55). 3. On the Remote Clipboard Configuration page, select whether you want the Remote Clipboard feature installed, and then select Next. NOTE: This setting controls whether Remote Clipboard components are installed. To change this setting after installation, you must uninstall and reinstall HP ZCentral Remote Boost Receiver. If installed, Remote Clipboard can be disabled (and re-enabled) later using HP ZCentral Remote Boost Receiver or the HP ZCentral Remote Boost Receiver Configuration tool. 4. If the next page of the wizard is titled Proxy Configuration, select the appropriate setting from the following list, and then select Next.

Installing HP ZCentral Remote Boost Sender (Windows)
The installer wizard for the HP ZCentral Remote Boost Sender allows for both Typical and Custom installations. The Typical installation installs Remote USB and Remote Clipboard but not smart card redirection. The Typical installation should be suitable for most deployments. The Custom installation lets you choose whether or not to install certain features. A custom installation can be performed on the command line as well. IMPORTANT: Windows administrator privileges are required to perform the installation. NOTE: If an older version of the software is already installed, installing a newer version will perform an update. Attempting to install the same version or an older version will cause the installer to exit without making changes to the system. NOTE: During the installation process, the installer creates a log file named rgsenderInstaller.log in the location specified by the Windows TEMP environment variable.

The following table describes the settings available in the Connection panel.

Table 4-7 Settings and their descriptions

Setting

Description

Prompt for user name and password

Forces the authentication prompt to display when you start an HP ZCentral Remote Boost connection. In certain scenarios, HP ZCentral Remote Boost does not prompt you to enter a domain, user name, and password when starting an HP ZCentral Remote Boost connection. If you need to enter a domain, user name, and password, then select this box. TIP: This is advantageous when you use HP ZCentral Remote Boost in Directory Mode, where each session has different connection needs.

Do not change the Sender display(s)

Do not change the resolution or layout of the sender's displays.

Attempts to set the sender's display resolution and layout to match the receiver's display resolution and layout. For example, if the receiver has two monitors side-by-side and an overall display resolution of 2560 × 1024, HP ZCentral Remote Boost attempts to set the same resolution and layout on the sender's displays. If that fails, HP ZCentral Remote Boost attempts to set a resolution of 2560 × 1024 on a single sender display. NOTE: This option is not supported on Linux by default. You must configure the X Server with the proper modelines, metamodes, or both for this option to work. See Matching display resolution and layout (Linux-based sender) on page 45 for more information.

Set Sender display(s) to match display properties

Attempts to set the sender's display resolution and layout to match the specified display properties. See Image and Display on page 63 for more information. NOTE: This option is not available if no display properties are found in the configuration file.

Automatically hide the menu bar and dock when in borderless mode NOTE: macOS only

If enabled, hides the menu bar and dock when the Receiver window is in borderless mode, similar to what happens when full-screen window mode is used.

Enable remote USB NOTE: Windows/HP ThinPro only

Advanced Video Compression on Sender NOTE: Windows/Linux only

Enables Advanced Video Compression.

Image Quality

Sets the maximum image quality. When not using Adaptive image quality, HP ZCentral Remote Boost will maintain the image quality specified by this option. When selecting Adaptive image quality, HP ZCentral Remote Boost will use this option's setting as the target image quality when the updates-per-second value allows.

Enable adaptive image quality Increase text rendering quality Minimum image quality Target update rate

When Enable adaptive image quality is selected, HP ZCentral Remote Boost will begin to degrade the image quality down to the Minimum image quality setting (from 0­100) anytime the updates-per-second value falls below the Target update rate (from 0­30 updates per second). When Increase text rendering quality is selected, HP ZCentral Remote Boost uses different encoding for areas of the sender's display with few colors (areas with mostly text) to increase the quality when those areas are displayed on the receiver. In videocentric or bandwidth-constrained environments, disabling this option might improve HP ZCentral Remote Boost performance. NOTE: These options are disabled when Advanced Video Compression is enabled.

TIP: See Performance optimization on page 84 for more information about ways to optimize HP ZCentral Remote Boost performance.

Gestures (Windows touch-capable devices only)
You can use the gesture settings to map hotkey sequences to the gestures that are not used by HP ZCentral Remote Boost by default. For a list of the gestures that you can customize, see Using touch features (Windows touch-capable devices only) on page 50.

issues.  Remote application termination--See Creating an agent for remote application termination (Windows
only) on page 96 for more information.  Other automated actions--The basic principle behind using the event log for remote application
termination can be used to create an agent that performs other automated actions.
Filtering access to HP ZCentral Remote Boost Senders
You can filter access to HP ZCentral Remote Boost Senders using either user names or network identifiers.
Filtering by user name
You can restrict HP ZCentral Remote Boost connections by configuring the Sender userfilter.txt file to specify the user names, or regular expressions to match the user names, that are allowed to make a connection. If the provided user name does not match one of the filters, the connection is denied. By default, the userfilter.txt file allows all user names. IMPORTANT: The userfilter.txt file must allow all user names when Easy Login is enabled. Remote Boost cannot filter connections by user name when using Easy Login because the first authentication step is skipped. The file userfilter.txt is located in the installation folder on Windows and in /etc/opt/hpremote/rgsender on Linux. NOTE: Administrator privileges are required to read or write to this file. User name entries in the userfilter.txt file are not case sensitive. Filtering is performed only on the user name portion of a user's credentials. This means a domain account with the same user name as a local account is treated as the same user name. As an example, if james is added to the userfilter.txt file on a sender system, connections from both the domain user corp.net\james and the local user james are allowed.
HP ZCentral Remote Boost Sender notification icon (Windows only) 27

Filtering by network identifiers
You can restrict HP ZCentral Remote Boost connections by configuring the Sender ipfilter.txt file to specify the IP addresses, subnet masks, and the fully qualified computer and domain names of the receiver systems that are allowed to make a connection. If a receiver does not match one of the filters, the connection will be denied. The file ipfilter.txt is located in the installation folder on Windows and in /etc/opt/hpremote/ rgsender on Linux. Connection filtering based on host name and domain name requires DNS to be configured to allow reverse DNS lookup. For example, if the receiver IP address is 10.13.19.1, the command nslookup 10.13.19.1 returns a host name and domain name. HP ZCentral Remote Boost similarly uses reverse look up for host name and domain name filtering. As an example, adding the following lines to the ipfilter.txt file on a sender system that allows only connections from receiver systems computername1 and computername2: HOSTNAME:computername1.networkdomain.name HOSTNAME:computername2.networkdomain.name Filtering on the domain name compares the text after the first period in the domain name. For example, if DNS reverse lookup returns james.auth.corp.net, the filter compares auth.corp.net against domain name entries in the ipfilter.txt file to determine whether to allow connections from the receiver. You can combine filter types in one ipfilter.txt file. After a match is made with a filter specified in the ipfilter.txt file, HP ZCentral Remote Boost stops processing the file and allows the connection to be made. By default, the ipfilter.txt file does not filter out any connections. If the receiver connects to the sender over VPN or through another process that causes the IP address to be translated, HP ZCentral Remote Boost might prevent connections that users expect to work. For additional information, review the ipfilter.txt file on a system where the HP ZCentral Remote Boost Sender has been installed.
28 Chapter 5 HP ZCentral Remote Boost Sender overview

6 Configuring certificates
By default, HP ZCentral Remote Boost Receiver attempts to verify the identity of the sender by verifying the sender public-key infrastructure (PKI) certificate before a connection is made. By default, HP ZCentral Remote Boost Sender creates a self-signed certificate, but you can configure it to use a certificate signed by a Certificate Authority (CA).
Sender verification
When the receiver attempts to connect to the sender, a warning is displayed if the certificate verification fails. The certificate verification can fail for the following reasons:  The sender presented a self-signed certificate. This user can compare the certificate fingerprint to the
fingerprint available in the Certificate panel of the HP ZCentral Remote Boost Sender Configuration tool. See End-user verification of a sender certificate on page 29. NOTE: This is the most common failure, because HP ZCentral Remote Boost Sender generates a selfsigned certificate by default.  The sender address typed into the receiver window does not match the hostname on the sender certificate. This failure occurs if the user connects with an IP address instead of using the sender hostname. The user must be sure that the IP address resolves to the hostname on the sender certificate before connecting to that sender. Alternatively, the user can reconnect using the hostname on the sender certificate.  The certificate is expired. If self-signed certificates are used, this error does not occur because a new self-signed certificate is generated when the current certificate approaches expiration.
Certificate Verification Error Policy
The Certificate Verification Error Policy determines how the receiver performs if the identity of the sender cannot be verified. This setting can be configured in the HP ZCentral Remote Boost Receiver Configuration tool (see HP ZCentral Remote Boost Receiver Configuration tool (Windows and Linux Only) on page 60). If the verification fails, the HP ZCentral Remote Boost Receiver can be configured to do one of the following:  Accept: Certificate errors are ignored, and the receiver connects to the sender.  Prompt to accept (default): A warning prompt is displayed, and the user can choose to connect despite
the failure. An SHA-256 fingerprint of the sender certificate is displayed with the error message. To verify the identity of the sender, compare the fingerprint displayed with the error message to the fingerprint presented in the Certificate panel of the HP ZCentral Remote Boost Sender Configuration tool. An administrator can provide the fingerprint to the user if they do not have access to the HP ZCentral Remote Boost Sender Configuration tool.  Deny: The receiver does not connect to the sender.
End-user verification of a sender certificate
If the receiver cannot verify the sender certificate and the Certificate Verification Error Policy is configured to prompt to accept, the user can verify that the fingerprint of the certificate displayed in the verification error
Sender verification 29

message matches the fingerprint displayed in the HP ZCentral Remote Boost Sender Configuration tool on the sender. An administrator can provide the fingerprint from the HP ZCentral Remote Boost Sender Configuration tool, if necessary.
Using a certificate signed by a CA
For ease in deployment, HP ZCentral Remote Boost creates a self-signed certificate for the sender. For greater security, HP ZCentral Remote Boost can be configured to use a certificate signed by a CA. To use a certificate signed by a CA, the CA certificate and key files must be present on the sender and receiver system.
Configuring the sender to use a certificate signed by a CA
You can configure the sender to use a certificate signed by a CA. For more information about setting HP ZCentral Remote Boost properties manually, see Setting HP ZCentral Remote Boost properties manually on page 76.
Modifying the sender Ice configuration file

To modify the sender configuration file: 1. Open the rgsenderconfig file. On Windows, the file is located in the HP ZCentral Remote Boost
Receiver installation directory. On Linux, the file is located in /etc/opt/hpremote/rgreceiver. 2. Remove the comment from the following line and change the value to 0:
Rgsender.Network.GenerateCertificate=0 After this procedure is complete, HP ZCentral Remote Boost does not generate new certificates or use a selfsigned certificate for sender verification. You must delete any existing HP ZCentral Remote Boost certificates from the file system. See Removing a certificate on page 32.
Modifying the receiver Ice configuration file
To modify the receiver Ice configuration file:
30 Chapter 6 Configuring certificates

1. If you provide a certificate signed by a CA to verify the sender, the receiver must verify that certificate when a connection is attempted. Add the following setting to enable the receiver to verify the sender certificate: IceSSL.VerifyPeer={0 | 1}  0: Do not verify the sender certificate.  1: Require a sender certificate and verify it.
2. If you configure a certificate signed by a CA for the sender, you must make sure that the receiver can access the same CA root certificate that is used to sign the sender certificate. Add the following setting: IceSSL.CAs=<file containing the certificate of a trusted CA> The file must be encoded using the P12 format.
Modifying the receiver configuration file
To modify the receiver configuration file: 1. Open the rgreceiverconfig file. On Windows, the file is located in the HP ZCentral Remote Boost

Modifying the sender Ice configuration file
By default, HP ZCentral Remote Boost does not create or use a receiver certificate. However, you can modify the sender Ice configuration file to verify the certificate that identifies the receiver. 1. You can also configure the sender to verify a certificate that identifies the receiver. Add the following
setting to enable the sender to verify the receiver certificate: IceSSL.VerifyPeer={0 | 1 | 2}  0: Do not verify the receiver certificate.  1: Verify the receiver certificate if it is provided, but do not require a receiver certificate.  2: Require a receiver certificate and verify it. 2. If you configure the sender to require a receiver certificate, you must make sure that the sender can access the same CA root certificate that is used to sign the receiver certificate. Add the following setting: IceSSL.CAs=<file containing the certificate of a trusted CA> The file must be encoded using the P12 format.

Removing a certificate

If certificate verification fails, the user can accept the certificate and connect when prompted. If the Don't ask about this certificate again check box is selected, HP ZCentral Remote Boost Receiver stores the end-user verification of the hostname and certificate. If a user tries to reconnect to the same hostname and the same certificate is presented by the sender, HP ZCentral Remote Boost Receiver automatically accepts or rejects the certificate based on the previous choice. This information is stored locally on the receiver. To stop automatically accepting or rejecting the certificate, you must remove the certificate from where it is stored.

Windows
To remove a certificate on Windows: 1. Open the Registry Editor and find the folder HKEY_CURRENT_USER/Software/HP/KnownSenders. 2. To clear all certificates, delete the KnownSenders folder. To remove a specific certificate, in the

7 Using HP ZCentral Remote Boost features
This chapter describes HP ZCentral Remote Boost features and topics.
HP ZCentral Remote Boost Advanced Features
This section discusses HP ZCentral Remote Boost Advanced Features.
Advanced Video Compression (Windows/Linux only)
Advanced Video Compression is an HP ZCentral Remote Boost Feature that enables the AVC (H.264) codec, instead of the HP3 codec, to reduce the network bandwidth for use cases like video where large desktop areas are changing frequently. Advanced Video Compression is ideal for video or 3D applications in textured mode. HP does not recommend it for use with wireframes or fine lines, because screen artifacts might appear when in motion. Advanced Video Compression can be enabled in the Performance panel of the HP ZCentral Remote Boost Receiver settings. IMPORTANT: Advanced Video Compression requires a one-time activation that occurs on the receiver when the first HP ZCentral Remote Boost connection is established, and this activation requires internet access. If using a proxy server for your LAN, be sure that your proxy settings are configured correctly (see Network on page 22). Activation does not work with a proxy autoconfiguration (PAC) file or with the Web Proxy AutoDiscovery (WPAD) protocol. The activation process uses https access to the activation.rgs.ext.hp.com URL (15.0.92.201). So you must configure your proxy or firewall to allow it. For thin clients with a write filter, HP recommends disabling the write filter before the first HP ZCentral Remote Boost connection so that the files created during activation are permanently written to the hard drive. The write filter should be re-enabled afterward. System requirements for Advanced Video Compression might be higher than the base HP ZCentral Remote Boost system requirements, all of which are described in the QuickSpecs (see Finding more information on page 4). NOTICE: The performance of Advanced Video Compression for resolutions larger than full HD (1920x1080) varies depending on the content.
HP Velocity
HP Velocity is an HP ZCentral Remote Boost Advanced Feature that improves performance within a wide area network (WAN). HP Velocity status is displayed on the HP ZCentral Remote Boost Receiver toolbar:  Blue: HP Velocity is monitoring network loss and is ready to be used.  Green: HP Velocity is actively working to improve network conditions.  Grey: HP Velocity has not been activated. NOTE: HP Velocity might increase network bandwidth usage.
34 Chapter 7 Using HP ZCentral Remote Boost features

NOTE: Certain system configurations might prevent HP Velocity from working. In that situation, HP Velocity is disabled. On macOS, HP Velocity needs the value of the system setting maxsockbuf to be at least 3 MB (3145728). You can check the current value by running the command sysctl -n kern.ipc.maxsockbuf on a terminal. If the current value is lower than 3145728, you can increase it by running the command sudo sysctl -w kern.ipc.maxsockbuf=3145728 on a terminal.
Authentication
HP ZCentral Remote Boost supports several authentication methods and smart card redirection.
Authentication methods
There are three different authentication methods available for an HP ZCentral Remote Boost connection.  Standard authentication: Supported for HP ZCentral Remote Boost Sender on Windows and Linux.  Easy Login: Supported for HP ZCentral Remote Boost Sender on Windows and Linux.  Single Sign-on: Supported for HP ZCentral Remote Boost Sender on Windows only. On Windows, the authentication method is selected during installation of HP ZCentral Remote Boost Sender and can be changed later using the HP ZCentral Remote Boost Sender Configuration tool (see HP ZCentral Remote Boost Sender Configuration tool (Windows/Linux only) on page 69). Smart card redirection is supported for standard authentication and Easy Login (see Smart card redirection on page 36). On Linux, Easy Login can be enabled during installation and disabled using an HP ZCentral Remote Boost Sender property (see Other global properties on page 78).
Standard authentication
To use standard authentication: Standard authentication is the process by which a local user attempts to connect to a sender that has neither Single Sign-on nor Easy Login enabled. In normal operation, users are required to authenticate twice when establishing an HP ZCentral Remote Boost connection from a receiver to a sender. The two steps are as follows: 1. The first authentication step is from HP ZCentral Remote Boost Receiver to HP ZCentral Remote Boost
Sender. The dialog for this authentication step is generated and displayed by HP ZCentral Remote Boost Receiver on the receiver. 2. The second authentication step is when logging in to or unlocking the sender desktop session. The login or unlock dialog is generated by the sender and is displayed in the HP ZCentral Remote Boost Receiver window on the receiver. NOTE: If another user is already logged in to the sender, the second authentication step does not take place. Instead, the currently logged-in user receives an authorization prompt to allow or deny the new user access to join the existing desktop session (see Collaboration on page 37 for more information). When a Windows Receiver and Windows Sender are in the same workgroup and the same user name and password are used on both systems, the first authentication step will be accomplished using a secure token. The user will not be required to enter a password. To connect as a different user, enable the prompt for user name and password setting (for more information, see HP ZCentral Remote Boost Receiver settings on page 19.)
Authentication 35

Using Kerberos Authentication
When a Windows or Linux Sender is connected to a Windows domain, the first authentication step can be accomplished using Kerberos when using a Windows Receiver connected to the same domain. The user is not be required to enter a password. Kerberos authentication to a Linux Sender requires a hostname to be entered as the Sender identifier. Kerberos authentication to a Linux Sender will not work with an IP address. To connect as a different user, enable the Prompt for user name and password setting (see HP ZCentral Remote Boost Receiver settings on page 19).
Easy Login
If you use Easy Login, the first authentication step (HP ZCentral Remote Boost authentication) is skipped. NOTE: At the login screen, you might see an additional user account named HP ZCentral Remote Boost ELO. Do not use this account to log in. Use your normal user account. NOTE: There are several issues that can prevent an Easy Login authentication. The Diagnostics panel of the HP ZCentral Remote Boost Sender Configuration tool can help troubleshoot these issues. See HP ZCentral Remote Boost Sender Configuration tool (Windows/Linux only) on page 69 for more details.
Single Sign-on
With Single Sign-on, the second (System) authentication is skipped. When connecting, the user will be prompted for user name a password. Upon verification, the user will be connected directly to the sender's desktop. NOTE: Single Sign-on does not support smart card or ActivKey authentication. NOTE: If you lock the desktop, you might see an additional user account named HP ZCentral Remote Boost SSO. Do not use this account to log in. Use your normal user account.
Smart card redirection
When smart card redirection is enabled, both the receiver and sender can access the same smart card that physically exists on the receiver-side only. This means that you can unlock the receiver desktop using the smart card, connect to the sender, and then use the same smart card with the sender desktop. NOTE: Smart card redirection is supported on Windows-based receivers and Windows-based and Linuxbased senders only. On Windows-based and ThinPro-based receivers, smart cards can be remoted using Remote USB. See Remote USB (Windows and ThinPro only) on page 54. NOTE: Smart card redirection can be used with standard authentication or Easy Login only. It cannot be used with Single Sign-on.
Using smart card redirection
To use smart card redirection: 1. Enable smart card redirection during the installation of both HP ZCentral Remote Boost Receiver and HP
ZCentral Remote Boost Sender (see Installation on page 6). 2. Install the vendor driver for the smart card reader on the receiver. 3. Install the vendor driver for the smart card on both the receiver and sender. 4. If Remote USB is enabled, see Configuring Remote USB for smart card redirection on page 37.
36 Chapter 7 Using HP ZCentral Remote Boost features

NOTE: If the smart card removal policy has been set on the receiver, the receiver desktop is locked if the smart card is removed. If the smart card removal policy has been set on the sender, the sender desktop is locked when the HP ZCentral Remote Boost connection is ended or when the smart card is removed.
Configuring Remote USB for smart card redirection
To prevent the smart card reader from being remoted: Smart card readers typically connect to the system via USB, so you must prevent the smart card reader from being remoted by the Remote USB feature to use the smart card redirection feature.  If you used the default Remote USB installation option USB devices are Local/Remote when installing
HP ZCentral Remote Boost Receiver, connect the smart card reader to the receiver before starting an HP ZCentral Remote Boost session, and do not disconnect the smart card reader during the session. ­ or ­ Set the remoting behavior of the smart card reader to local (see Configuring the remoting behavior of individual USB devices (Windows only) on page 55).
Limitations
Consider the following limitations when using smart card redirection:  Smart card redirection is limited to the primary user.  Smart card redirection is limited to the first smart card detected by the receiver. If there are two or more
smart cards, including virtual smart cards, enabled on the receiver, smart card redirection might not be predictable.  Disconnecting and reconnecting a smart card reader during an HP ZCentral Remote Boost session causes the smart card reader to be remoted via Remote USB. In this situation, the receiver no longer sees the smart card reader or smart card. If the smart card removal policy is enabled, the receiver desktop locks.
Collaboration
HP ZCentral Remote Boost enables the primary user to share their desktop session with several users simultaneously. This feature can be used in a variety of collaborative scenarios including classroom instruction, design reviews, and technical support. A collaboration session is created when one or more users are authorized by the primary user to connect to the primary user's desktop session. This allows all users to view and interact with the primary user's desktop.
Collaboration 37

Table 7-1 Collaboration session items and their descriptions

Item

Description

1

Sender: Hosts HP ZCentral Remote Boost Sender, which transmits the sender desktop session to HP ZCentral Remote

Boost Receiver on each receiver.

2

Primary user: The primary user is logged into the sender and has control over the session. The primary user authorizes

who can join and actively participate in the session.

3

Collaborators: Collaborators, once authorized, can view the sender's desktop and make changes as permitted by the

primary user.

NOTE: The image above is just an example of one possible configuration. Any combination of hardware supported by HP ZCentral Remote Boost Receiver can be used by the primary user and collaborators.

The user currently controlling the mouse and keyboard is called the floor owner. Only one user, the floor owner, can interact with the desktop at a time. To transition the floor owner, the current floor owner must cease using the keyboard or mouse for 0.5 seconds. If another user uses the mouse or keyboard while the current floor owner is inactive after this period, floor ownership transfers to the new user. TIP: The delay's value of 0.5 seconds can be changed using the HP ZCentral Remote Boost Sender Configuration tool on Windows (see HP ZCentral Remote Boost Sender Configuration tool (Windows/Linux only) on page 69 for more information). Click the HP ZCentral Remote Boost Sender notification icon in the Windows notification area to open the HP HP ZCentral Remote Boost Collaborators window, which allows you to do the following:  View who the primary user and collaborators are  Enable or disable collaborator input for individual collaborators or all collaborators at once by clicking
the appropriate mouse pointer icon TIP: Individual collaborator input can also be enabled when authorizing the collaborator to connect by selecting Enable Input for this user in the authorization dialog.  Disconnect individual collaborators or all collaborators at once by clicking the appropriate X icon

38 Chapter 7 Using HP ZCentral Remote Boost features

Note the following additional information about collaboration:  Collaboration requires unique login credentials on the sender for each participant.  If guest accounts are enabled in Windows, a collaborator can join by using "Guest" as the user name and
leaving the password blank. However, only one guest collaborator can join at a time. If another guest collaborator joins, the first one will be kicked out of the session.  On Windows, if the primary user disconnects, the desktop is locked, but all collaborators will remain connected. On Linux, if the primary user disconnects, the desktop is locked, and all collaborators are disconnected.  The update rate of all collaborators is limited by the lowest update rate of any one collaborator. Collaborators with low update rates can use the Performance panel in the HP ZCentral Remote Boost Receiver settings to improve their update rate, which will improve the experience for all collaborators.  To collaborate in a session that has Advanced Video Compression or HP Velocity enabled, each collaborator must have the same Advanced Video Compression and HP Velocity settings on their HP ZCentral Remote Boost Receiver, or the connection will be refused.
Collaboration invitations
You can invite other users to either new collaboration sessions or sessions in progress. Collaboration invitations can be generated in the HP ZCentral Remote Boost Collaborators window by selecting the copy to clipboard button. Invitations are copied to the clipboard and can be pasted into an email or messaging app to send them to the other users. Invitations contain brief instructions to help the invited users connect to the sender, including the hostname of the sender machine and a list of IP addresses that can be used. By default, only global addresses are displayed. To change this default behavior, modify the value of the HP ZCentral Remote Boost Sender sender_gui.Invitation.FilterPrivateAddresses configuration property (see Setting HP ZCentral Remote Boost properties manually on page 76). Setting this property to 1 (the default) filters private addresses. Setting it to 0 displays private addresses in the list.
Display
You can configure several display settings.
Display resolution and layout matching
Many HP ZCentral Remote Boost scenarios require that the resolution and display layout transmitted by the sender match the display configuration on the receiver. The following sections describe how to configure the sender if HP ZCentral Remote Boost is unable to match the resolution and display layout by default.
Multi-monitor overview
During an HP ZCentral Remote Boost connection, HP ZCentral Remote Boost transmits the sender's entire desktop area to the receiver. If the sender has more monitors or higher-resolution monitors than the receiver, scroll bars appear in the HP ZCentral Remote Boost Receiver window so that you can view the sender's entire desktop area. If the sender has multiple monitors, it might be beneficial to use the options described in Matching display resolution and layout (Windows-based sender) on page 42 or Matching display resolution and layout (Linuxbased sender) on page 45.
Display 39

Multiple monitors on the receiver are also useful for a many-to-one connection. If the receiver is connected to two senders, each sender frame buffer can be displayed on its own monitor if the receiver has two monitors (see the following image).
NOTE: On macOS, to allow a Receiver window to span multiple monitors, HP recommends that you do not select the Displays have separate Spaces OS option. To change this setting, open System Preferences, and then select the Mission Control preference pane. NOTE: On macOS, selecting the following settings can improve the usability of the Receiver, especially if the Receiver window covers the entire screen. Under System Preferences, select Dock, and then select Automatically hide and show the Dock. Then, under System Preferences, select General, and then select Automatically hide and show the menu bar.
Matching display resolution and layout methods
There are four ways to have HP ZCentral Remote Boost automatically configure the sender's display resolution and layout:  Per-session preferred resolution properties: These properties, if enabled, set the preferred width and
height of the resolution for session number <n>. 40 Chapter 7 Using HP ZCentral Remote Boost features

­ Rgreceiver.Session.<n>.VirtualDisplay.IsPreferredResolutionEnabled ­ Rgreceiver.Session.<n>.VirtualDisplay.PreferredResolutionHeight ­ Rgreceiver.Session.<n>.VirtualDisplay.PreferredResolutionWidth NOTE: If IsPreferredResolutionEnabled is true for any session, HP ZCentral Remote Boost disables all other display resolution and layout matching methods.  Per-session display properties: Per-session display properties can be set in the configuration file or used in an auto-launch file. See Auto-launch properties on page 82. The per-session display properties can be used to describe the resolution, position, and orientation of one or more displays. Each display has the following fields where <n> is the session number and <x> is a display number: ­ Rgreceiver.Session.<n>.Display.<x>.X ­ Rgreceiver.Session.<n>.Display.<x>.Y ­ Rgreceiver.Session.<n>.Display.<x>.Width ­ Rgreceiver.Session.<n>.Display.<x>.Height ­ Rgreceiver.Session.<n>.Display.<x>.Orientation NOTE: For more information about these properties and their expected values, see Using display properties to set resolution and layout on page 46. NOTE: If any per-session display property is in the configuration file, HP ZCentral Remote Boost disables the Set Sender display(s) to match Receiver display(s) and the Set Sender display(s) to match display properties settings.  Set Sender display(s) to match Receiver display(s): If the Set Sender display(s) to match Receiver display(s) setting is enabled, HP ZCentral Remote Boost automatically tries to set the resolution and display layout of the sender to match that of the receiver. You can also control this function with the following properties: ­ Rgreceiver.IsMatchReceiverResolutionEnabled ­ Rgreceiver.IsMatchReceiverPhysicalDisplaysEnabled NOTE: By default IsMatchReveiverPhysicalDisplaysEnabled is enabled when the Set Sender display(s) to match Receiver display(s) setting is enabled.  Set Sender display(s) to match display properties: If the Set Sender display(s) to match display properties setting is enabled, HP ZCentral Remote Boost automatically tries to set the resolution and display layout of the sender to match the specified display properties. NOTE: The Set Sender display(s) to match display properties option is disabled if no display properties were found in the configuration file. The display properties can be used to describe the resolution, position, and orientation of one or more displays. Each display has the following fields where <x> is a display number: ­ Rgreceiver.Display.<x>.X ­ Rgreceiver.Display.<x>.Y ­ Rgreceiver.Display.<x>.Width
Display 41

­ Rgreceiver.Display.<x>.Height ­ Rgreceiver.Display.<x>.Orientation NOTE: For more information about these properties and their expected values, see Using display properties to set resolution and layout on page 46. You can also enable the Set Sender display(s) to match display properties with the Rgreceiver.UseDisplayProperties property.
Matching display resolution and layout (Windows-based sender)
When attempting to match the resolution and display layout, the most important thing to remember is that the sender must support the same resolution and layout as the receiver. Testing the resolution To avoid possible resolution-matching problems, test the resolution in advance using the following procedure: 1. Establish an HP ZCentral Remote Boost connection with the Do not change the sender display(s)
setting enabled. 2. When the connection is established, manually attempt to set the sender's resolution to match the
receiver's resolution. If you can match the resolution, then HP ZCentral Remote Boost can also do it for you automatically. Additional configuration on the sender Depending on the NVIDIA® GPU and driver you are using, you might need to perform additional configuration on the sender. The required configurations can vary depending on the hardware, described as follows:  Blade workstation: If the sender is a blade workstation, then its NVIDIA driver exposes all display outputs to the operating system as if they have monitors attached. The resolutions provided by the NVIDIA driver cover a broad range of settings and should meet most user needs. If the resolution you want is not available, see Adding custom resolutions on page 44.  Virtual workstation: If the sender is a virtual workstation with a hypervisor, the NVIDIA driver presents a single display to the operating system. The resolutions provided by the NVIDIA driver cover a broad range of settings and should meet most user needs. If you are using a single display at the receiver, no further action is required. If you need to configure additional resolutions and/or make additional displays available, see NVIDIA resolution-matching (Windows-based senders with NVIDIA graphics only) on page 43.  Traditional workstation: If the sender is a traditional workstation, then its NVIDIA driver expects to find a display attached to one or more outputs. When it does, it queries the EDID (Extended Display Information Data) information from the display for its supported resolutions and makes the display and resolutions available to the operating system. On Windows 7, if there is not a display attached, the NVIDIA driver reverts to a single VGA output with basic display resolutions. For servers, rack-mounted workstations, and non-NVIDIA graphics, use an EDID emulator device or create an EDID file to allow resolution matching. See Creating and applying an EDID file on page 44 and Matching display resolution and layout (Windows-based sender) on page 42 for more information. Alternatively, HP ZCentral Remote Boost will load EDID files automatically. See NVIDIA resolution-matching (Windows-based senders with NVIDIA graphics only) on page 43.  Headless workstation:When connecting to a workstation that has no physical displays connected, HP ZCentral Remote Boost requires that an EDID be loaded first. HP ZCentral Remote Boost can be
42 Chapter 7 Using HP ZCentral Remote Boost features

configured to automatically load a custom EDID which supports most resolutions up to 4k. To enable automatic EDID loading on headless workstations with Nvidia GPU: 1. In rgsenderconfig, set Rgsender.Compatibility.Displays.ForceEdidOnHeadless to 1. 2. Restart the HP ZCentral Remote Boost Sender service. ­ or ­ Restart the sender. NOTE: This property will only apply an EDID to a system if it is headless when the HP ZCentral Remote Boost Sender service starts. If the workstation is not headless when the HP ZCentral Remote Boost Sender service starts, then no EDID will be loaded. NVIDIA resolution-matching (Windows-based senders with NVIDIA graphics only) NVIDIA resolution-matching provides the following additional features over the default resolution-matching method:  Automatic loading and unloading of EDID files to allow a sender with fewer monitors than the receiver to "fake" displays NOTE: This is especially useful for virtual workstations where the hypervisor typically provides only one display.  Rotated monitors on virtualized systems (specifically, Citrix and VMware® virtual machines)  Automatic application of custom resolutions on virtualized systems NOTE: If NVIDIA resolution-matching fails to match the requested resolution/resolutions, HP ZCentral Remote Boost attempts the default resolution-matching method. To enable NVIDIA resolution-matching: 1. In rgsenderconfig, set Rgsender.Compatibility.Displays.AllowNvidiaResolutionMatching to 1. 2. Restart the HP ZCentral Remote Boost Sender service. ­ or ­ Restart the sender. NOTE: For more information about setting the property, see Setting property values in a configuration file on page 76. NOTE: NVIDIA resolution-matching is enabled by default on Windows 10 Redstone 1 and later but must be enabled on Windows 7, Windows 8.1, and Windows 10 pre-Redstone. EDID files Extended Display Identification Data (EDID) data is a standardized means for a display to communicate its capabilities, such as resolution and video characteristics, to a source device. This allows the source device (PC, graphics card) to generate the necessary graphics that match the needs of the system. EDIDs provide a powerful and convenient method for HP ZCentral Remote Boost to manage complex customer requirements.
Display 43

Creating and applying an EDID file There are software tools available to create and edit an EDID file, but the easiest method is to use an existing monitor from the receiver, temporarily attaching it to the sender and using the NVIDIA Control Panel to export the EDID file. If you have several different displays that you use on the receiver, HP recommends that you capture the EDID information of the monitor that has the highest display resolution. This will address all other resolution needs.
Creating an EDID file To create an EDID file: 1. Attach a monitor to the sender or the receiver. NOTE: This is not possible with blade workstations that use MXM graphics. 2. Open the NVIDIA Control Panel and select View system topology. 3. Find and select EDID for the connected monitor. 4. The Manage EDID dialog box opens. Select the tab labeled Export. 5. Select a display and select Export EDID and save the output to a file. This file can be imported on the sender system.
Importing an EDID file To import an EDID file: 1. On the sender system, under View system topology select EDID on the connector port you want to use. 2. In the Manage EDID dialog box , select the Load tab and then Browse and select the EDID file you created. 3. Under Connector select the port (DVI, DisplayPort) that you want to use for the EDID monitor. 4. Select Load EDID. The EDID information is applied. 5. Select OK and then select cancel to close the Manage EDID dialog box. NOTE: If you apply the file to multiple DisplayPort connectors, HP ZCentral Remote Boost can able to support multi-display configurations. Under the View System Topology screen of the NVIDIA Control Panel, you should now be able to see that an EDID file has been applied to the DisplayPort connectors that you selected. HP ZCentral Remote Boost can now match the specified display resolution and display layout.
Adding custom resolutions To add a resolution that is not already supported by the NVIDIA driver: 1. Open the NVIDIA Control Panel and select Change Resolution. 2. Select Customize. 3. Select the Enable resolutions not exposed by the display check box, and then select Create Custom Resolution. NOTE: If a warning appears, accept it. 4. Add the custom resolutions.

Matching display resolution and layout (Linux-based sender)
When attempting to match the resolution and display layout, the sender must support the same resolution and layout as the receiver. If the resolution is not supported, HP ZCentral Remote Boost instead uses the preferred resolution of the sender from the file xorg.conf. For example, if the receiver has dual monitors set at a 1280 ×1024 resolution, HP ZCentral Remote Boost asks the sender to set its resolution to 2560 ×1024. If the resolution is not supported, HP ZCentral Remote Boost instead uses the preferred resolution of the sender from the file xorg.conf. The easiest way to check whether the sender can match the receiver resolution is to attempt to set the resolution on the sender manually. If you can set the resolution manually, then HP ZCentral Remote Boost can do it for you automatically. If you cannot set the resolution manually, you must modify the file xorg.conf to support the additional required resolutions. To test whether you can match the resolution manually, establish an HP ZCentral Remote Boost connection with the Do not change the sender display(s) setting enabled. After you establish an HP ZCentral Remote Boost session, open an X terminal window and use the xrandr tool to list all the currently supported resolutions for the X server. You can also use the tool to configure the X server display settings, including size and orientation. Previous releases of the X Window System used the file /etc/X11/xorg.conf to store initial setup information. When a change occurred with the monitor or video card, you were required to edit the file manually. Although current releases of Red Hat® Enterprise Linux® (RHEL) have largely automated the process, you still need to edit the file to support configurations where no monitor is attached or where you want the X server to simulate that it has a different monitor attached to it with different resolution capabilities. Similarly, this is also the case when you want to match the receiver's resolution in an HP ZCentral Remote Boost session where the X server cannot determine the capabilities of the receiver's monitors. NOTE: Some window managers (such as GNOME) allow you to modify display preferences, which can sometimes result in the creation of the following file: $HOME/.config/monitors.xml When you log in to the system and a window manager starts a session, it uses information from this file to set the current desktop resolution. This can reverse the resolution matching performed by HP ZCentral Remote Boost and cause the desktop to be set to an inappropriate resolution. For example, if you set the desktop resolution of the sender to 1024 × 768 using a window manager, that resolution is stored in monitors.xml. If an HP ZCentral Remote Boost connection is then established with display resolution matching enabled on a receiver with a resolution of 1920 × 1200, the sender display resolution changes to 1920 × 1200 and then to 1024 × 768. There is no notification that the resolution match request failed (because it did not). To avoid this behavior, avoid setting the resolution using window manager controls. It is safe to delete monitors.xml to restore display resolution matching functionality. See the documentation for your operating system or window manager for more information about where and how it manages display settings.
Configuring the X server The X server can be configured in several different ways.
Scenario 1: All receivers have the same configuration If all receivers have the same configuration, then using the Virtual entry under the Screen section of the file xorg.conf is the easiest method.
Display 45

For example, if all receivers have four monitors configured at 1280x1024 each, configure the X server to run at a resolution of 5120x1024 by making the following additions to the file xorg.conf. Add the following under the Device section: Option "UseDisplayDevice" "none" Option "UseEDID" "false" Add the following under the Screen section: SubSection "Display" Virtual 5120 1024 Depth 24 EndSubSection Now the X server is configured to have a single screen running at a resolution of 5120 × 1024, which covers all four of the receiver's monitors. You can use this method to support a very large virtual display limited only by frame buffer memory. Scenario 2: Some receivers have different configurations In the more likely scenario where you need to support many display resolution and monitor configurations, you can configure the X server to think it has the monitor with the highest resolution used on any of the receivers. This allows the X server to support as many display resolutions as possible. You do this by capturing the EDID information from the monitor (see Creating an EDID file on page 46) and making the following additions to the file xorg.conf. The following example uses dual HP LP2465 displays. The following text is added under the Device section of xorg.conf: Option "ConnectedMonitor" "DFP-0,DFP-1" Option "CustomEDID" "DFP-0:/etc/X11/lp2465edid.bin;DFP-1:/etc/X11/ lp2465edid.bin" To see which ports to use to handle higher resolutions, see the Xorg.0.log. If you have AMD graphics or the EDID file sent to the X server fails, you can use an EDID emulator. Creating an EDID file To create an EDID file:  Use the NVIDIA tool nvidia-settings to create an EDID file in either .bin or .txt format.
IMPORTANT: A physical display must be attached before you can use the NVIDIA tool. TIP: You can also use the method for Windows described in Creating and applying an EDID file on page 44 and copy the EDID file to the Linux system.
Using display properties to set resolution and layout
You can use the display properties to describe the resolution, position, and orientation of one or more displays. You can configure each display using the following fields:
46 Chapter 7 Using HP ZCentral Remote Boost features

 X: The X position of the upper-left corner of the display.  Y: The Y position of the upper-left corner of the display.  Width: The width of the display.  Height: The height of the display.  Orientation: The orientation of the display. Can be one of the following values:
­ 0: Landscape ­ 1: Portrait ­ 2: Landscape (flipped) ­ 3: Portrait (flipped) NOTE: If a field is not specified, the default value is 0. For the display properties to be valid, the following conditions must be met:  There must be at least one display specified.  Display numbers must start at 1 and be sequential.  One display must be at the origin where X=0 and Y=0.  Each display's width and height must be greater than 0.  A display's width must be greater than its height when its orientation is Landscape or Landscape (flipped).  A display's height must be greater than its width when its orientation is Portrait or Portrait (flipped). When more than one display is specified, the additional conditions must be met:  No display can overlap another display.  All displays must be adjacent to at least one other display. This means that all displays must be one X or Y position away from another display along one of the display edges. The display properties are validated during the connection attempt. If this validation fails, an error dialog box is displayed and the connection uses the sender's current configuration. For example, see the following display properties. These properties define two 1920 × 1200 displays that are positioned side by side. Rgreceiver.Display.1.X=0 Rgreceiver.Display.1.Y=0 Rgreceiver.Display.1.Width=1920 Rgreceiver.Display.1.Height=1200 Rgreceiver.Display.1.Orientation=0 Rgreceiver.Display.2.X=1920 Rgreceiver.Display.2.Y=0 Rgreceiver.Display.2.Width=1920 Rgreceiver.Display.2.Height=1200 Rgreceiver.Display.2.Orientation=0
Display 47

Sender screen blanking
HP ZCentral Remote Boost Sender, by default, blanks the screen of the sender monitor (if one is connected) so that the desktop session is not visible on the sender side. IMPORTANT: Screen blanking is not supported if the sender is a virtual machine. The default behavior is that the sender screen, with the exception of the cursor, blanks to black when you start an HP ZCentral Remote Boost session. The sender screen is displayed after the HP ZCentral Remote Boost session is ended. See the following additional information about HP ZCentral Remote Boost Sender screen blanking:  There might be a delay of up to 2 seconds after an HP ZCentral Remote Boost session is started before
the sender screen is blanked.  If, for any reason, HP ZCentral Remote Boost Sender is unable to blank the sender screen, a warning
dialog is displayed on the receiver.  If the sender is an HP workstation, then most input from any physically connected keyboards or mice at
the sender side is blocked while screen blanking is occurring. When HP ZCentral Remote Boost Sender receives keyboard or mouse input from HP ZCentral Remote Boost Receiver, the sender monitor enters a power-saving mode, which blanks the cursor as a result.  The ctrl + alt + del key sequence is not blocked by HP ZCentral Remote Boost Sender for any physically connected keyboards at the sender side. When this sequence is input into the sender using a physicallyconnected keyboard, the Windows logon screen of the remote desktop is displayed at the receiver side in the HP ZCentral Remote Boost Receiver window. The sender monitor remains blank while this occurs, but the monitor will exit its power-saving mode, and sender keyboard input is not blocked until the logon screen is closed.  Screen blanking can be disabled using the HP ZCentral Remote Boost Sender Configuration tool (see HP ZCentral Remote Boost Sender Configuration tool (Windows/Linux only) on page 69).
Input
Supported input devices and methods include Wacom, Gestures (Windows touch capable devices only), Game Mode (Windows only), and all keyboard layouts.
Wacom solution
The HP Remote Boost Receiver (Windows, macOS, RHEL, and Ubuntu) now supports Wacom pen displays and pen tablets when used with a Remote Boost Sender.
Adjusting tablet properties
You can make adjustments to Wacom display mapping, Express Key buttons, and pen buttons on the receiver system. Use the following on the receiver to adjust settings and to verify that the pen is working properly:  Windows: Wacom Tablet Properties application.  macOS: Wacom Tablet controls under System Preferences.  Linux: Wacom Tablet controls under the Devices section of Settings.
48 Chapter 7 Using HP ZCentral Remote Boost features

Windows and Mac receiver solution
Wacom drivers must be installed on the receiver system. Consider disabling the Remote USB feature on the receiver. If the Wacom USB connection is made after the Remote Boost connection is established, the Wacom device is captured and exported to the sender. HP does not recommend this setup, because it bypasses the Remote Boost Wacom solution. You can use Wacom Tablet controls to specify application-specific behavior on the receiver. This feature is not supported for sender applications, because Wacom controls are not available on the sender. Changing Wacom Tablet controls on the receiver will apply to all sender applications. Consider disabling touch (if supported) on the Wacom device. Having touch enabled can cause the receiver to use the touch interface, or it might cause interference with pen events.
ThinPro receiver solution
The ThinPro 7.1 receiver can allow a Wacom device to be virtually attached to a Linux sender. For best results, the receiver and sender should have a single display with matching resolutions. The usage of Remote USB and the usage of a Wacom pen are mutuallly exclusive. To enable the usage of a Wacom pen, open USB Manager as a privileged user in the ThinPro Control Panel and set the USB protocol to Local. To allow the receiver access to the Wacom devices, you must copy the rgs-pen-tablet.rules file from /opt/ hpremote/rgsreceiver/rules into the /etc/udev/rules.d folder. After copying the file, you must unplug the Wacom device from the receiver system or restart the receiver system. After plugging in the Wacom device, the pen should be able to move the cursor on the receiver system before establishing a remote connection. After the receiver is connected to a Linux sender, the Wacom input devices are captured. To verify that the device is exported to the sender system, enter the command xinput list on the sender system. When the Wacom devices are exported correctly, the output shows a list of Wacom devices. You can use the Wacom input devices within HP ZCentral Remote Boost receiver window. You need a mouse to interact with the receiver interface and the local desktop. NOTE: A Wacom pen does not respect floor control in a collaboration session. Multiple users attempting to simultaneously provide any kind of input might experience unwanted behavior.
Linux receiver solution (non-ThinPro) When installing the Remote Boost receiver, do not use the -legacyWacom installer flag or answer yes when prompted to enable Legacy Wacom support. These commands enable the older Linux Wacom solution, which works only from Linux receivers to Linux senders. NOTE: This does not include ThinPro. See ThinPro receiver solution on page 49 for more information.
Windows sender solution
Wacom drivers are not required on the sender system. If they are installed, the Wacom Tablet controls do not show the device as being connected. You must make any adjustments to the Wacom device on the receiver system. Configure applications on the sender using Windows Ink. Some applications use only the Wacom Wintab API rather than Windows Ink and do not work with this solution. Most pen-enabled applications use Windows Ink by default or can be configured to use Windows Ink. Updated versions of pen-aware applications tend to have better support for Windows Ink.
Input 49

When using the pen for input on the sender, the cursor is often displayed as as small dot. This is expected behavior. Windows has a setting to hide the pen cursor. Use Pen & Windows Ink controls in Windows Settings to specify definite behavior.

Linux sender solution
Wacom Tablet controls on the sender do not show the device as being connected. Make adjustments to the Wacom device on the receiver system. Some GTK-based applications require manual configuration to enable the virtual Wacom device. It appears on configuration menus as Remote Boost Wacom Tablet. One common application where this is necessary is the image manipulation program GIMP. 1. To enable the virtual Wacom device in GIMP, select EditInput Devices. 2. From the popup window that appears, select Remote Boost Wacom Tablet eraser and set the mode to
Screen. 3. Repeat the previous step for the Remote Boost Wacom Tablet stylus.
NOTE: Setting the device mode to Window could result in a cursor offset. This configuration step should only be necessary the first time you use the virtual with this applicaton. Other applications might have different menus to enable the virtual device.

Using touch features (Windows touch-capable devices only)
HP ZCentral Remote Boost supports the following touch features. NOTE: HP ZCentral Remote Boost does not support touch features for Windows 7.  Gestures--See the following table for more information.  Virtual keyboard and virtual mouse--You can access the virtual keyboard and virtual mouse from the
HP ZCentral Remote Boost Receiver toolbar. The virtual mouse provides a visual indication of the remote cursor position, which is normally not present in the tablet GUI. The virtual mouse is useful when precise cursor positioning or hovering is required. TIP: The virtual mouse can also be enabled and disabled using the four-finger tap gesture.  Hotkey sequence mapping--See Gestures (Windows touch-capable devices only) on page 21 for more information. The following table describes the gestures supported by HP ZCentral Remote Boost. IMPORTANT: A press is 0.5 seconds or more, and a tap is less than 0.5 seconds.

Game Mode (Windows only)
Game Mode lets you lock the cursor inside the HP ZCentral Remote Boost Receiver window to perform functions that rely on relative cursor movements, such as 3D environment interaction. If Game Mode is not enabled, such interactions might cause erratic cursor behavior. You can set the default state of Game Mode (enabled or disabled) with the HP ZCentral Remote Boost Receiver Configuration tool or Receiver Configuration File. You can toggle game mode on and off while HP ZCentral Remote Boost Receiver is in Setup Mode by pressing the G key.
Supported keyboard layouts
All keyboard layouts and languages are supported.
Remote Audio
Remote Audio allows audio generated by the sender to play back on the speakers of the receiver.
HP ZCentral Remote Boost audio path
The following sequence describes the path taken by audio during an HP ZCentral Remote Boost connection: 1. Software on the sender generates audio output. 2. The audio output is routed to HP ZCentral Remote Boost Sender using a physical or virtual audio device.

Remote Audio 51

3. HP ZCentral Remote Boost Sender encodes and transmits the audio output to HP ZCentral Remote Boost Receiver on each receiver.
4. HP ZCentral Remote Boost Receiver decodes and sends the audio output to the audio mixer of the operating system.
5. The audio mixer of the operating system sends the audio to the default audio playback device. 6. The audio device plays the audio output on a connected audio peripheral, such as a speaker. NOTE: Sounds that play through an internal speaker, such as the ToggleKeys sound on Windows, are not captured by HP ZCentral Remote Boost. For information about the audio settings in HP ZCentral Remote Boost Receiver, see Audio on page 21. For Remote Audio troubleshooting tips, see Remote Audio issues on page 92.
Using Remote Audio (Windows-based sender)
On Windows, Remote Audio works by default. If the sender has an audio device, the HP ZCentral Remote Boost Sender installation process detects it. If the sender does not have an audio device (or if you disable all audio devices before installation of HP ZCentral Remote Boost Sender), then the HP Remote Audio virtual audio device is also installed during the HP ZCentral Remote Boost Sender installation process and is used by HP ZCentral Remote Boost instead.
Using Remote Audio (Linux-based sender)
On Linux, some manual configuration might be required for Remote Audio depending on the audio capture method you intend to use. If the sender has an audio device, HP ZCentral Remote Boost supports two different methods of audio capture:  PulseAudio: See PulseAudio on page 52.  Advanced Linux Sound Architecture (ALSA): See ALSA on page 53. The following property specifies which audio capture method will be used (see Other global properties on page 78 for more information): Rgsender.Audio.Linux.RecorderApi NOTE: Some audio device drivers might not have the capability to capture application-generated audio.
PulseAudio
Any audio device that is configured for PulseAudio can be used. PulseAudio provides a software interface similar to the Stereo Mix capability for ALSA. PulseAudio also provides a dummy device that allows the audio system to function when no hardware audio devices are available. When using PulseAudio to capture audio, HP ZCentral Remote Boost Sender attempts to detect and connect to the monitor of the default playback device of the sender automatically. Explicit control of the PulseAudio capture device is available through the following property (see Other global properties on page 78 for more information): Rgsender.Audio.Linux.DeviceName If this property is set, HP ZCentral Remote Boost Sender attempts to connect to the device specified by this property. The command pactl list is useful for determining the PulseAudio device names. To capture
52 Chapter 7 Using HP ZCentral Remote Boost features

ALSA

from a specific device, specify the corresponding PulseAudio monitor source string (such as alsa_output.pci-0000_00_1b.0.analog-stereo.monitor). PulseAudio allows the user to configure and control the audio devices in the system. Changing the output device during an HP ZCentral Remote Boost session results in a loss of audio. To restore audio, either reselect the original device or stop and start the audio stream using the audio settings in HP ZCentral Remote Boost Receiver.
When using the ALSA audio system to capture audio, an audio device must be installed on the sender for application-generated audio to be sent to the receiver. Furthermore, the audio device installed in the sender must have the ability to record from a control that is the mix of all audio signals. On a Windows computer, by way of comparison, this control is often called Stereo Mix. Linux, however, does not follow a standard naming convention for this control, hence the need to evaluate individual audio devices to determine their suitability for use on Linux. The audio devices on Linux are not consistent in the naming conventions of the audio controls. The HP ZCentral Remote Boost Sender installer will attempt to adjust volume levels for known audio devices to allow audio to be captured. This section describes how to adjust volume levels for the supported audio devices. This information may be helpful for configuring audio devices that are not currently supported by the HP ZCentral Remote Boost Sender installer. Volume levels can typically be adjusted through the Volume Control application. This is usually found in the gnome panel or the system preferences menu. The Volume Control application may not show all available volume controls. The preferences for the Volume Control application may need to be adjusted to allow access to hidden volume controls. The alsamixer is a command-line tool for adjusting volume. This application will not hide audio controls like its GUI counterpart; however, it is not as intuitive. Press the h key after running alsamixer to get additional information about how to control capture volumes. Unsupported PCI audio devices are known to allow capture of application generated audio. The names of the controls that need to be adjusted are not consistent. Names of controls that might need to be adjusted include PCM, Capture, and Mix. You must specify the device where the audio is recorded by using the following property: Rgsender.Audio.Linux.DeviceName Run the command: cat /proc/asound/devices From this, you can see a list of the audio devices that looks something like this: 0: [ 0] : control 1: : sequencer 8: [ 0- 0]: raw midi 16: [ 0- 0]: digital audio playback 17: [ 0- 1]: digital audio playback 24: [ 0- 0]: digital audio capture 32: [ 1] : control 33: : timer 48: [ 1- 0]: digital audio playback

Remote Audio 53

56: [ 1- 0]: digital audio capture Use an audio device only if it contains the word capture (device number 24 or 56 in the previous example). Between each pair of square brackets, the first number is the sound card and the second number is the mixer device. Use the following syntax to set the audio capture device, where <c> is the sound card number and <d> is the mixer device number: Rgsender.Audio.Linux.DeviceName=plughw:<c>,<d> Using the previous example, you could specify audio device number 24 like in the following example: Rgsender.Audio.Linux.DeviceName=plughw:0,0 You could alternatively specify audio device number 56 like in the following example: Rgsender.Audio.Linux.DeviceName=plughw:1,0
Remote Clipboard
Remote Clipboard allows you to cut, copy, and paste data between the receiver and the sender or between two different senders. Copying, cutting, and pasting text is supported on Windows, Linux, and macOS. Copying, cutting, and pasting an image is only supported between a Windows-based sender and Windows-based receiver. In addition, copying, cutting, and pasting images is only supported for individual images. You cannot copy, cut, or paste groups of images or image and text combinations. On Windows, Remote Clipboard must be enabled during both the HP ZCentral Remote Boost Sender and HP ZCentral Remote Boost Receiver installations (see Installation on page 6). On Linux, Remote Clipboard is installed by default. On Windows, Linux, and macOS, Remote Clipboard must also be enabled in HP ZCentral Remote Boost Receiver (see Connection on page 20). TIP: Setting the logging level of HP ZCentral Remote Boost Receiver or HP ZCentral Remote Boost Sender to DEBUG enables Remote Clipboard log information.
Remote USB (Windows and ThinPro only)
Remote USB allows USB devices physically attached to the receiver to be virtually attached (mounted) to the sender. This gives the sender direct access to the USB devices, as if the devices were physically attached to it. See the following list for information about Remote USB support:  The sender must be Windows-based.  The receiver can be either Windows-based or ThinPro-based.  A receiver's physically-attached USB devices can be collectively attached to a single sender. The devices
cannot be split between multiple senders, nor can they be collectively attached to multiple senders.  HP ZCentral Remote Boost supports all four USB data transfer types (bulk, isochronous, interrupt, and
control).  USB devices that adhere to the USB 1.x or 2.x standard should work. However, webcams and devices that
are sensitive to timing might experience decreased performance, or they might not function at all. HP recommends thoroughly testing any USB device intended for use with HP ZCentral Remote Boost.
54 Chapter 7 Using HP ZCentral Remote Boost features

 USB 1.x and USB 2.x devices are supported on USB 3.x ports, but USB 3.x devices are not supported.  File copies might take longer due to the additional overhead of the network protocol on top of the USB
protocol.
Configuring the remoting behavior of individual USB devices (Windows only)
The remoting behavior for individual USB devices can be altered from what was set globally during installation. IMPORTANT: This configuration requires modifications to the Windows registry on the receiver. Registry modifications should be made with extreme caution, and you should always make a backup of the registry prior to making any changes. To configure the remoting behavior of a USB device: 1. Find the vendor ID and device ID for the USB device (see Determining USB device information (Windows)
on page 57). 2. Open the Registry Editor and create the following registry key:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hprpusbh \Parameters\Device 3. Create the following registry key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\hprpusbh \Parameters\Device\VID_VendorID&PID_ProductID 4. For the key you just created, create a string value named Mode. 5. Set the value of Mode to auto, local, or remote. NOTE: If set to auto, the USB device switches its mounted location between the sender and the receiver at the start and end of an HP ZCentral Remote Boost connection respectively. If set to remote, you must physically disconnect the USB device from the receiver after the HP ZCentral Remote Boost session ends and then reconnect the USB device for it to be usable on the receiver.
USB microphones
The Remote USB driver (on the receiver) supports the USB isochronous data type, which is commonly used for streaming data such as that generated by audio and video devices. This enables certain isochronous USB microphones to be accessed directly by the sender in the same manner as other USB devices. To remotely attach USB microphones to the sender, either of these Remote USB Configuration settings can be selected:  USB devices are Remote--If selected, a USB microphone can be accessed anytime by the sender.  USB devices are Local/Remote--If selected, how the USB microphone can be accessed by the sender
depends on when the microphone is connected to the receiver relative to establishment of the HP ZCentral Remote Boost connection: ­ If the microphone is connected to the receiver after establishment of an HP ZCentral Remote Boost
connection, the microphone will be a remote device only and can be accessed directly by the sender. TIP: The Windows Recording devices dialog in the sender allows the user to set the default sound recording device (microphone).
Remote USB (Windows and ThinPro only) 55

Remote USB Access Control List

HP ZCentral Remote Boost Sender supports an Access Control List (ACL) file that contains rules that specify whether to allow a Remote USB connection from a USB device on the receiver side.
Each rule in the ACL file has a type of allow or deny. The rules are evaluated for each Remote USB connection request as described:
 If any rule indicates the USB connection should be denied, the connection is denied, regardless of any other rule.
 If any rule indicates the USB connection should be allowed, and if there are no rules that deny the connection, the connection is allowed.
 If no rules match at all, the connection is denied.
The ACL file is implemented in XML format and is accompanied by an XSD (XML Schema Definition) file that defines the XML elements. The default ACL file hprDefaultUsbAcl.xml and the XSD file hprUsbAcl.xsd are both in the HP ZCentral Remote Boost Sender installation directory.

TIP: You can specify different files using the HP ZCentral Remote Boost Sender Configuration tool (see HP ZCentral Remote Boost Sender Configuration tool (Windows/Linux only) on page 69).

The default ACL file contains the following contents, which allows all USB connections to be made:

<hprUsbAcl> <ruleset> <rule type="allow"> <name>Allow all USB devices (HP default)</name> </rule> </ruleset></hprUsbAcl>
Rules can contain the filters described in the following table.

TIP: See hprUsbAcl.xsd for examples of using filters.

Determining USB device information (Windows)
To determine USB device information: 1. Open Device Manager and find the USB device under Universal Serial Bus controllers. 2. Double-click the USB device, and then select the Details tab in the window that appears. 3. Determine the vendor ID, product ID, class, subclass, and protocol.
a. Select Hardware Ids from the drop-down menu. The vendor ID and product ID are displayed in the following format: USB\VID_<vendor ID>&PID_<product ID> In the following example, the vendor ID is 1234 and the device ID is 5678: USB VID_1234&PID_5678
b. Select Compatible Ids from the drop-down menu. The class, subclass, and protocol are represented by numerical codes and are displayed in the following format: USB\Class_<class code>&SubClass_<subclass code>&Prot_<protocol code> In the following example, the class code is 08, the subclass code is 06, and the protocol code is 50: USB Class_08&SubClass_06&Prot_50
Determining USB device information (Linux)
You can use open-source software to determine USB information about Linux. To determine USB device information, use an open source program named USBView, which is available at http://sourceforge.net/projects/usbview.
Enabling Remote USB on HP ThinPro
Remote USB can be enabled for HP ZCentral Remote Boost Receiver on HP ThinPro if the sender is Windowsbased. To enable Remote USB on HP ThinPro: 1. In HP ThinPro, open the USB Manager and set the USB protocol to HP ZCentral Remote Boost. 2. Restart the thin client. 3. Ensure that Enable remote USB is enabled in HP ZCentral Remote Boost Receiver.
Directory Mode
Directory Mode lets you connect to multiple senders simultaneously from a single receiver. When you start HP ZCentral Remote Boost Receiver in Directory Mode, it looks for a directory file containing user names and computer names. HP ZCentral Remote Boost Receiver reads this file and attempts to connect to each specified sender automatically. The default directory file is directory.txt in the HP ZCentral Remote Boost Receiver installation directory. NOTE: This file contains examples that are commented out using the number sign (#) character.
Directory Mode 57

Directory file format
The directory file is often a common file for a group, department, organization, or an entire company. The directory file can manage and administer the senders for any number of users. HP recommends that you save the directory file on a readily accessible network file share or mapped drive so it can be shared by multiple receivers. The directory file is a text file with the following format for each user: <domain name> <user name> <computer name> [<computer name> ...] The domain name of a Windows-based receiver depends on the environment. For a domain account, using the example worldwide\user1, the domain name used for Directory Mode would be worldwide. The following example directory file specifies the senders for user1 and user2 in a domain account environment: worldwide user1 RC_1 RC_2 RC_3 worldwide user2 RC_4 RC_5 RC_6 For a local account, using the example user1_computer\user1, the domain name used for Directory Mode would be user1_computer. The following example directory file specifies the senders for user1 and user2 in a local account environment: user1_computer user1 RC_1 RC_2 RC_3 user2_computer user2 RC_4 RC_5 RC_6 For Linux-based receiver, use UNIX as the domain name. The domain name does not apply when using the directory file for Linux users. Instead, use the keyword UNIX in place of the domain name. For example: UNIX user1 RC_1 RC_2 RC_3 If the user name contains white-space characters, the name can be enclosed in double-quotes as shown: domain1 "user1 user" RC_1 RC_2 RC_3 domain1 "user2 user" RC_4 RC_5 RC_6
Starting HP ZCentral Remote Boost Receiver in Directory Mode (Windows)
You can verify the HP ZCentral Remote Boost Receiver connection and then start Directory Mode.

Setting HP ZCentral Remote Boost properties manually
You can configure HP ZCentral Remote Boost properties manually.
Property syntax
The following example shows the HP ZCentral Remote Boost property syntax:
Rgreceiver.Network.Timeout.Warning=10000
In this example, the name of the property is Rgreceiver.Network.Timeout.Warning, and the value of the property is 10000. This setting specifies that HP ZCentral Remote Boost Receiver will wait 10,000 milliseconds (10 seconds) before displaying a warning dialog that indicates that it is no longer able to communicate with HP ZCentral Remote Boost Sender. This particular setting is duplicated in the Network panel of the HP ZCentral Remote Boost Receiver settings. A property could also be set to an empty value like in the following example:
Rgreceiver.Browser.Name=
Properties with empty values reset to their default values:  If the value of the property is of type string, the value will be set as an empty string.  If the value of the property is of type int, int vector, or bool, the value will be set to 0.
IMPORTANT: No user notification is provided if a property name is misspelled, and the property will not take effect. If you specify a property in a configuration file or on the command line and it does not take effect, verify that the property name is spelled correctly (including uppercase and lowercase usage).
Setting property values in a configuration file
HP ZCentral Remote Boost property values can be set in a configuration file. The Receiver configuration file is named rgreceiverconfig and the Sender configuration file is named rgsenderconfig. On Windows, the files are located in the HP ZCentral Remote Boost Receiver or the HP ZCentral Remote Boost Sender installation directory. On Linux, the files are located in /etc/opt/hpremote/rgreceiver or /etc/opt/hpremote/rgsender. On macOS, the rgreceiverconfig file is located in /Library/ Application Support/HP/rgreceiver.
The configuration files contain one property per line. All properties in the configuration files are initially commented out with the # character. To set a property in a configuration file, first delete the number sign ( #) character preceding the property name, and then set the property to the appropriate value. For HP ZCentral Remote Boost Receiver, once a property is uncommented in the configuration file, the property's setting is persisted when HP ZCentral Remote Boost Receiver is closed.
IMPORTANT: After an HP ZCentral Remote Boost Receiver property is persisted, commenting out the property in the configuration file again will not reset its value to default. To reset a value to default, set the property back to its default value in the configuration file, and leave the line uncommented.

76 Chapter 8 Configuration tools and properties

NOTE: If a property is listed more than once, the value of the last entry is used. NOTE: HP ZCentral Remote Boost properties set in a configuration file might not take effect until the computer is restarted.
Setting property values on the command line
Property values for HP ZCentral Remote Boost Receiver on Windows and Linux, and for HP ZCentral Remote Boost Sender on Windows, can be set on the command line. For examples, see HP ZCentral Remote Boost Receiver command-line options on page 24 and HP ZCentral Remote Boost Sender command-line options (Windows) on page 25. NOTE: Per-session property values cannot be set on the command line.
Making a property immutable
The following section describes how to make properties immutable. Every property can be locked down to prevent changing its value via one of the following sources:  Inside the application  User launch file  Command Line  Automation API restriction
NOTE: In order to lock a property with Automation API restriction its mutability must be set to zero. This is done manually by adding the IsMutable variation of any property to the administrator config file. The following is an example of the syntax for locking a property: The property to lock: Rgreceiver.Network.Timeout.Warning=10000 The properties IsMutable variant: Rgreceiver.Network.Timeout.Warning.IsMutable=0 Once a property has been set to immutable its value and mutability state cannot be changed by any of the sources listed above.
Automation API restriction control
The following section describes how to change the restriction state for the automation API. The default configuration of the Receiver initializes the automation API to be in a restricted state. This means that if a property is made Immutable, any requests on the automation API will not be initiated. This behavior can be changed via the property: Rgreceiver.Properties.AutomationApi.UnRestricted This property can only be changed using the administrator configuration file. If this property is set to "1" any requests on the automation API to change the value or mutability of a property will be initiated.
Setting HP ZCentral Remote Boost properties manually 77

IMPORTANT: The automation API is accessible to the local user. Therefore, by enabling the property above, any property may be changed by utilizing the automation API. This means there is a path for nonadministrator users to bypass any properties the administrator has made immutable.

Auto-launch properties

Auto-launch files for HP ZCentral Remote Boost Receiver have the extension .rgreceiver and use the same syntax for setting property values as rgreceiverconfig.
Use a text editor to create an auto-launch file. You can customize your auto-launch file for your environment using both the properties described in this section and other Receiver properties described throughout this guide.
See Setting HP ZCentral Remote Boost properties manually on page 76.
When an auto-launch file is opened, HP ZCentral Remote Boost Receiver starts automatically and attempts to establish a connection to a single sender, as configured in the file.

NOTE: Auto-launch files do not support starting HP ZCentral Remote Boost connections to multiple senders. For information about connecting to multiple senders, see Directory Mode on page 57.

The following table describes the auto-launch properties. Because you can auto-launch only one connection at a time, the session number should always be 0.

9 Performance optimization
Use the general and network suggestions to optimize performance.
General
The following suggestions apply to all operating systems:  Enable HP Velocity (see HP Velocity on page 34 for more information).  Set the sender desktop background to a solid color to minimize the amount of image data that needs to
be sent.  Set both the receiver and the sender display depth to 32 bits per pixel.  Lower the sender's display resolution.  Increase the Max Image Update rate from 30 to 60 using the HP ZCentral Remote Boost Sender
Configuration tool.  Reduce the Remote Audio quality setting in HP ZCentral Remote Boost Receiver, or disable Remote Audio
if it is not needed. The following suggestion applies to Windows only:  Adjust the Windows system performance settings in Control Panel. The Adjust for best performance
option will minimize the bandwidth requirements for HP ZCentral Remote Boost.
Network
HP ZCentral Remote Boost depends on low network latency and reasonably high network bandwidth. There are several methods to test and measure the network bandwidth, latency, and the number of hops between the receiver and the sender:  Use the ping command to measure network latency.  Use the Traceroute (Linux) or tracert (Windows) command, which will report the number of hops
it takes to reach a computer in addition to the network latency.  Use the tools NTttcp Utility, ipref, or something similar, which are available at
https://gallery.technet.microsoft.com/NTttcp-Version-528-Now-f8b12769. After you characterize your network performance, you can decide if improvement is required. The network interface will auto-negotiate the network speed with the network switches on the local network. Most modern network interfaces and switches will negotiate the highest possible speed available. However, unless the network has been carefully designed for maximum throughput, the network interfaces and switches might auto-negotiate to a suboptimal speed. If the network interface and switches are configured to auto-negotiate properly, you can leave the settings to auto-negotiate. If you want to force the network to operate at a particular speed, the settings in the network interface and switches can be hard-coded. You must be careful with these settings, however. If the network interface and switch settings don't complement each other, the network will have poor performance.
84 Chapter 9 Performance optimization

Forcing a network speed (Windows)
To configure a network interface to force a particular network speed on Windows: 1. In Control Panel, select Device Manager. 2. Expand Network adapters. 3. Right-click the network adapter that you want to configure, and then select Properties. 4. Select the Advanced tab. 5. In the list of properties, locate the property that controls the speed and duplex setting. The name can
vary, but it is usually something like Speed & Duplex or Link Speed & Duplex. 6. From the Value drop-down list, select the fastest speed your network can support, and be sure to select
the Full Duplex version of that speed.
Forcing a network speed (Linux)
To configure a network interface to force a particular network speed on Linux:  As root, use a command like in the following example. This example sets network interface 0 as a 100
Mb/sec connection running full duplex mode: $ /usr/local/sbin/ethtool -s eth0 speed 100 duplex full autoneg off Your network is now configured. If you are not satisfied with your network performance, look at the log files on your network switch (if the receiver is connected to one). A significant number of errors on the switch port may indicate that the computer or network is not configured correctly. Work with your IT organization to optimize your computer and network configuration.

Failed connection attempts
This section describes the most common issues that cause HP ZCentral Remote Boost connection attempts to fail.
Receiver checklist
Use the following checklist to troubleshoot failed connection attempts from the receiver side: 1. Verify that you are entering the correct hostname or IP address for the sender.
If you changed the port that HP ZCentral Remote Boost Sender listens on from its default of 42966, you must specify the port number along with the hostname or IP address like in the following examples: MyHostName:12345 192.168.0.10:12345 2. Verify that the receiver is on the same network as the sender. 3. Verify that the receiver can ping the sender. 4. If the receiver is behind a firewall, verify that the firewall supports network address translation (NAT).
Sender checklist
Use the following checklist to troubleshoot failed connection attempts from the sender side: NOTE: After going through this checklist, be sure that you log out of the sender before attempting an HP ZCentral Remote Boost connection again. 1. Verify the credentials for the user account you are trying to access from the receiver. The account
password cannot be blank. 2. Verify that HP ZCentral Remote Boost Sender has started on the sender (see HP ZCentral Remote Boost
Sender overview on page 25 for more information). 3. Verify that all tests pass on the Diagnostics panel of the HP ZCentral Remote Boost Sender Configuration
tool. 4. If the sender is behind a firewall, verify that the firewall supports network address translation (NAT) and
port forwarding. 5. If you changed the network interface binding of HP ZCentral Remote Boost Sender from its default of
listening to all network interfaces, verify that the sender is listening on the correct network interface (see Sender network interface binding on page 87 for more information). 6. (Windows only) Verify that the sender is not using Automatic Private IP Addressing (APIPA) by typing the following in a command window:
86 Chapter 10 Troubleshooting

netstat -n -a If the IP address associated with the HP ZCentral Remote Boost Sender listening port (42966 by default) is private, APIPA is the likely cause. For information about how to disable APIPA, go to http://support.microsoft.com/kb/220874. 7. (Linux only) a. Verify that the sender is not using an X desktop started on the command line. The rgsender service
waits for an X server to be started by the system display manager. The rgsender service logs information to the /var/opt/hpremote/rgsender/rg-svc.log file. Examine this file for error messages. b. Linux systems joined to a Windows domain might require files to be configured in the /etc/sssd folder. After joining the system to the domain, install the HP ZCentral Remote Boost Sender after to allow these files to be created with proper values.
Kerberos
Kerberos authentication is available only on a Windows receiver. The receiver must be connected to the same Windows domain as the Windows or Linux sender. Kerberos authentication requires that the HP ZCentral Remote Boost Receiver and HP ZCentral Remote Boost Sender systems have synchronized clocks. Some tolerance is allowed for clock differences. The tolerance is dependent on parameters setup on the domain controller. In order to allow the Kerberos ticket to be used for login on the sender, the Rgsender.KerberosLogon property needs to be set and the domain controller needs to have delegation enabled for the computer. This feature may not be configured for all services. Other PAM services may be able to authenticate with the Kerberos ticket by adding auth sufficient pam_rg.so to the associated PAM service in /etc/pam.d. This must be added before the authentication line that includes password-auth, system-auth, or common-auth. A Linux sender must be identified by the hostname and not an IP address in order for the receiver to obtain the necessary service ticket. The service ticket for a host with the name hostname.example.com can be seen by running the command line program klist on the receiver. This ticket will be listed with the server name host/hostname.example.com.
Sender network interface binding
HP ZCentral Remote Boost Sender is set by default to listen to all network interfaces present on the sender. If this is undesirable, the network interface binding can be manually reconfigured. There are three methods to reconfigure HP ZCentral Remote Boost Sender network interface binding:  Disable the network interfaces that you do not want HP ZCentral Remote Boost Sender to listen to, and
then restart the sender. HP ZCentral Remote Boost Sender will then bind to the remaining enabled network interface. The disadvantage of this method is that the other network interfaces will no longer be usable.  Manually configure the network interface that you want to use to be the one listened to by HP ZCentral Remote Boost Sender. See Reconfiguring network interface binding manually on page 88 for more information.  Use the HP ZCentral Remote Boost Sender Configuration tool to specify which network interface to listen to. See Reconfiguring network interface binding using the HP ZCentral Remote Boost Sender Configuration tool on page 88 for more information. If you enter a host name instead of an IP address when establishing an HP ZCentral Remote Boost connection, it is possible that the host name resolves to the IP address of an incorrect network interface. This could be caused by a number of factors, including how your DHCP and DNS servers are configured.
Failed connection attempts 87

If the host name resolves to the IP address of an incorrect network interface, do one of the following:  Enter the IP address that HP ZCentral Remote Boost Sender is bound to instead of the host name when
establishing an HP ZCentral Remote Boost connection.  Reconfigure your DHCP and DNS servers so that the host name resolves to the correct IP address.  Use the nslookup command to determine the IP address that the host name resolves to, and then
follow the steps in Reconfiguring network interface binding manually on page 88 to set the corresponding network interface to be listed first in the list of connections.
Reconfiguring network interface binding manually
To manually configure which network interface the sender binds to: 1. Disable the Listen for HP ZCentral Remote Boost connections on all network interfaces option in the
HP ZCentral Remote Boost Sender Configuration tool. NOTE: See HP ZCentral Remote Boost Sender Configuration tool (Windows/Linux only) on page 69 for more information. 2. Select the network icon in the Windows notification area, and then select Open Network and Sharing Center. 3. Select Change adapter settings in the left pane. 4. Press the Alt key to show the menu bar, select Advanced, and then select Advanced Settings. 5. In the Adapter and Bindings panel, use the arrow buttons next to the Connections pane to move the network interface that you want to the top of the list. The network interface at the top of the list will be the one listened to by HP ZCentral Remote Boost Sender.
Reconfiguring network interface binding using the HP ZCentral Remote Boost Sender Configuration tool
To reconfigure the network interface binging using the HP ZCentral Remote Boost Sender Configuration tool, you must determine the number that corresponds to the network interface and then configure the appropriate settings. Determining the number that corresponds to the network interface Before configuring options in the HP ZCentral Remote Boost Sender Configuration tool, you must determine the number that corresponds to the network interface you want HP ZCentral Remote Boost Sender to listen to. To do this, follow these steps: 1. Select the network icon in the Windows notification area, and then select Open Network and Sharing
Center. 2. Select Change adapter settings in the left pane. 3. Press the Alt key to show the menu bar, select Advanced, and then select Advanced Settings. 4. In the Adapter and Bindings panel, look at the list of network interfaces in the Connections pane.
The number that corresponds to the network interface at the top of the list is 0. The number for the next network interface in the list is 1, and so on.
88 Chapter 10 Troubleshooting

Configuring the HP ZCentral Remote Boost Sender settings After determining the number that corresponds to the network interface that you want, follow these steps to configure the appropriate HP ZCentral Remote Boost Sender settings: 1. Disable the Listen for HP ZCentral Remote Boost connections on all network interfaces option in the HP ZCentral Remote Boost Sender Configuration tool. 2. Set the value of the Listen to a specific network interface option in the HP ZCentral Remote Boost Sender Configuration tool to the number of the network interface. NOTE: See HP ZCentral Remote Boost Sender Configuration tool (Windows/Linux only) on page 69 for more information.

Network timeouts
The network timeout properties of HP ZCentral Remote Boost Receiver and HP ZCentral Remote Boost Sender provide a way to handle network disruptions. Although TCP/IP is reliable, it does not guarantee network packet delivery. Possible issues include the following:  Network over-subscription, resulting in congestion and packet loss  CPU utilization by other processes and tasks, starving the TCP/IP network stack  Incorrectly configured or malfunctioning network switches, routers, and network interfaces See the following sections for a list of timeout-related issues and solutions.

Graphical issues (Linux)
Use these sections to resolve graphical issues on Linux.
Full-screen crosshair cursors
Some software uses large crosshair cursors that might not display correctly on the receiver. Full-screen crosshair cursors can be disabled by typing the following in an X terminal: xprop -root -remove _SGI_CROSSHAIR_CURSOR

90 Chapter 10 Troubleshooting

Gamma correction on the receiver
The color in a 3D application on the sender can look incorrect when displayed on a receiver. This is because the gamma of the receiver monitor does not match the gamma of the sender monitor. Any tool that can adjust the gamma for a display can help resolve this issue. Some tools adjust the gamma for the entire display, while others adjust the gamma on a per-window basis. A per-window tool that can adjust the HP ZCentral Remote Boost Receiver window only should provide the best results.
Black or blank HP ZCentral Remote Boost Receiver window
If the sender is set to less than 24 bit or 32 bit color depth (depending on the graphics adapter), the HP ZCentral Remote Boost Receiver window might display a black or blank desktop session. Increase the color depth of and restart the sender usually resolves the issue.
High DPI display issues
HP ZCentral Remote Boost is DPI based and scales UI elements to be more readable depending on the resolution (Linux) or display scale factor (Windows). For optimal performance, consider the following:  On Linux, you can change both the resolution and scale factor percentage in the desktop display settings
applet. The system desktop scale factor does not affect the HP ZCentral Remote Boost Receiver. The receiver automatically selects an integral scaling factor based on the display size and resolution. Therefore, other applications might appear to be scaled differently than HP ZCentral Remote Boost.  On Windows, scaling is done on integral scale factors only. (That is, 100%, 200%, and so on.) Nonintegral scale factor values, such as 150%, are rounded to the nearest integral value. Therefore, HP ZCentral Remote Boost might appear to be scaled more or less than other applications.  Windows supports per-monitor scaling. If multiple monitors are configured with different scale factors, you might need to resolve the following issues: ­ When HP ZCentral Remote Boost UI windows are moved from one screen to another, they are
repainted to the new screen scale factor. This can cause visual artifacts in the title bar from the repaint. To remove these artifacts, minimize and restore each window. ­ If the receiver is in 1:1 Pixel Mode, the new window size does not match the content it previously displayed. To resolve this issue, either resize the window to fit the sender window using the ++ hotkey sequence, or switch to Scaled Pixel Mode using the receiver toolbar.
Disabling or enabling support for high DPI displays
To disable or enable support for high DPI displays:  On HP ZCentral Remote Boost Receiver, modify the following property in the configuration file:
Rgreceiver.EnableHighDPIScaling 0: DPI awareness is disabled. 1: DPI awareness is enabled. This is the default setting.
Input issues
See the following sections for a list of input-related issues and solutions.
High DPI display issues 91

Keystrokes are repeated when connected to Linux Sender
To resolve this input issue, disable key repeats or lengthen the delay before a key repeat occurs by using xset on the Linux Sender. NOTE: The following options must be set every time you run HP ZCentral Remote Boost. To disable key repeat, use the following command: xset -r To lengthen the delay before a key repeat occurs, use the following command: xset r rate <delay in milliseconds>
NOTE: By default, the autodelay repeat is typically 500 ms. Start by increasing this delay to approximately the duration of your connection latency.

Remote Audio issues

Remote USB issues
The following information describes Remote USB troubleshooting tips.  Verify that Remote USB is enabled in HP ZCentral Remote Boost Receiver.  Verify that the USB device is physically connected to the receiver, powered, and turned on.  Verify that the USB device is detected by the receiver.
­ Windows: Verify that Device Manager shows an instance of HP Remote Physical USB under Universal Serial Bus controllers for each device that is remotely connected to the Sender.
­ ThinPro: Run the command lsusb -t in a terminal and look for Driver=usb-remote. This driver confirms that the device was claimed by the usb-remote driver and can potentially be used with Remote USB.
 Verify that the USB device is detected by the sender. ­ Windows: Verify that the USB device is listed in Device Manager. Open Device Manager, select HP Remote Virtual USB, enable Devices by Connection from the View menu, and verify devices listed under HP Remote Virtual USB.
 Verify that both the sender and the receiver support Remote USB (see Remote USB (Windows and ThinPro only) on page 54).
 Verify that the USB device is supported (see Remote USB (Windows and ThinPro only) on page 54).  Uninstall and reinstall HP ZCentral Remote Boost Receiver to be sure that Remote USB is configured
correctly during installation (see Installing HP ZCentral Remote Boost Receiver (Windows) on page 6).  Uninstall and reinstall HP ZCentral Remote Boost Sender, and be sure that Remote USB is enabled during
installation (see Installing HP ZCentral Remote Boost Sender (Windows) on page 9).  Verify that the drivers and software required by the USB device are installed and available on the sender.
Many USB devices require manufacturer-supplied software to work. This software must often be installed before the USB device is connected to the computer.
Smart card redirection issues
Consider the following when troubleshooting smart card redirection:  Verify that the smart card works standalone on both ends of a connection.  Verify that vendor drivers are installed for the smart card reader and the smart card devices.  Be sure that only the primary user is attempting to use a smart card.

Remote USB issues 93

 Verify that there is only one active smart card connected to the receiver. A virtual smart card is counted as an active smart card.
 If the smart card service on RHEL 7 does not start correctly, you might need to modify the pcscd startup script located at /usr/lib/systemd/system/pcscd.service. Open the script for editing and change the ExecStart option to the following: ExecStart=/usr/sbin/pcscd --foreground --auto-exit -c /etc/ reader.conf.d/hpremotescr.conf
Mouse Cursor issues on servers and blades (Windows Sender)
VMouseSetup.exe must be installed on systems without a physical pointer device (for example, servers or blade workstations) on Windows 8 and later. VMouseSetup.exe will install a Virtual Pointer Driver to enable HP ZCentral Remote Boost to correctly display the mouse cursor on systems without a pointer device. VMouseSetup.exe is included in the HP ZCentral Remote Boost Install package for the Windows Sender.

A Switching between HP ZCentral Remote Boost and Remote Desktop Connection (Windows only)
You can switch between an HP ZCentral Remote Boost session and a Windows Remote Desktop Connection session without having to log out of the remote desktop on the sender as long as you use the same credentials for both sessions. The existing session is ended when you start the new session using the other program. If you try to use different credentials to start a Remote Desktop Connection session with a sender that is already in an HP ZCentral Remote Boost session, Remote Desktop Connection allows you to force a logoff for the remote user account currently in the HP ZCentral Remote Boost session. Forcing a log off requires Windows administrator privileges and ends the HP ZCentral Remote Boost session. If you try to use different credentials to start an HP ZCentral Remote Boost session with a sender that is already in a Remote Desktop Connection session, HP ZCentral Remote Boost displays an authorization failure message. You cannot force a logoff in this scenario. IMPORTANT: See the following information about security and authentication concerns:  If you switch from an active Remote Desktop Connection session to an HP ZCentral Remote Boost
session, the remote desktop might enter into a logged on and unlocked state. You might want to avoid this if an unlocked remote desktop is a security concern. To avoid this, log off of the remote desktop using Remote Desktop Connection before starting the HP ZCentral Remote Boost session.  If you have an active Remote Desktop Connection session that you authenticated using a smart card and try to switch to an HP ZCentral Remote Boost session using Easy Login on a receiver other than the one that started the active Remote Desktop Connection session, HP ZCentral Remote Boost prompts you for your user name and password, which is not normally required for Easy Login authentication. If you do not know your user name and password because you normally use smart card authentication, you cannot switch to an HP ZCentral Remote Boost session. In this scenario, the Remote Desktop Connection session must be ended manually to release the smart card reader for use by HP ZCentral Remote Boost.

B Creating an agent for remote application termination (Windows only)

When an HP ZCentral Remote Boost session is unintentionally ended, you might want applications on the sender to be terminated to prevent them from operating unsupervised. This appendix describes how to create an agent on the sender that provides remote application termination by monitoring events in the HP ZCentral Remote Boost Sender event log HPRemote.

Viewing the HPRemote log
To view the HPRemote log: 1. Select Start, select Control Panel, select Administrative Tools, and then select Computer
Management. 2. In the left pane, select System Tools, select Event Viewer, and then select HPRemote. The HPRemote log contains information about recent HP ZCentral Remote Boost connection activity. By default, the most recent events are listed first. To view the properties of an event, double-click it to open the Event Properties window.
NOTE: For additional information about Windows event logging, go to Microsoft® Developer Network (MSDN) at http://msdn.microsoft.com/.

HPRemote log format

Data in the HPRemote log consists of a message ID followed by optional data in both string and binary formats.

The following table describes the events logged in the HPRemote log. The message IDs are defined in the header file RgsenderEvents.h and are 32 bit values. The EventID is from the Code field within the message ID and, for the HPRemote log, ranges from 1 to 13.

Agent design guidelines
Designing an agent to provide Remote Application Termination requires consideration of a number of issues in order to minimize data loss and determine when a last-resort shutdown of a disconnected desktop session is required. Listed in the following sections are several topics to consider when designing application control agents for your environment. The topics are not exhaustive--use them as a starting point for a more complete design that meets your business requirements.
Desktop session logout
In some circumstances, loss of a primary user connection should trigger a full shutdown of all applications and force a logout of the desktop session (perhaps after a specified time limit for reconnection has expired). This action would drop all connections to the remote session.  Benefit: Implementing a full desktop session shut down/logout ensures that all connection activity
ceases immediately and ensures that applications are prevented from further unattended actions. Shut down of a remote session frees the workstation for connection by other users. This approach is the most absolute and secure solution for desktop session management. The agent relies upon Windows logout routines to terminate environment.  Issue: Forcing a desktop session shutdown or logout can result in data loss for any open applications on the desktop session. Forcing session logouts can result in application alert prompts requiring user interaction to save altered data. These prompts can delay or halt an interactive logout. Session termination also destroys memory of window placement on the desktop and requires user intervention at restart.
Selective environment shutdown
Partial shutdown of an environment terminates only specific applications. It does not implement a full desktop session logout. It selectively protects only the most critical applications requiring oversight and control.  Benefit: Preserves the active desktop session for connection at a later time. Selectively terminates the
applications of interest. Preserves data not governed by an automated shutdown policy. Supports session recovery with an arbitrary connection time. If done in layers (giving some applications more time than others), then a gradual "soft landing" shutdown can occur that ultimately results in a full logout. Idle resources over a specific amount of time can be returned to a remote server pool.  Issue: Potentially more complicated to implement. Can require coordination of multiple agents to handle layered shutdown. May still result in data loss for specific applications. May also require a primary semaphore to halt or terminate multiple agents if the user reconnects and wants to stop the shutdown process.
Wrapping applications of interest
You can launch agents that supervise only specific applications in a given environment. Tying agents to specific applications is a selective safety net for every user.  Benefit: Application-specific agents can be implemented as plug-ins or support utilities for an
application. In the future, certain software providers may provide custom interfaces for safe shutdown messages from an agent or the operating system. Custom agents can be independently maintained and tied to specific application releases for greater support flexibility. Independent agent design supports unit testing and decouples environmental dependencies.  Issue: Users need specific recourse to disarm an agent if they reconnect. Applications may not interact well with a dedicated agent (and only shut down due to a global shutdown request). Dedicated agents could possibly be compromised.
100 Appendix B Creating an agent for remote application termination (Windows only)

Administrator alerts
Instead of shutting down an environment, you can design an agent to alert an administrator or operator to determine the status of the user before taking action. This watchdog approach can further be defined to exploit redundant network connection support to a remote system to allow user-directed shutdowns to occur.  Benefit: System agents are not required to take destructive action--they serve only as alarms and
monitors for alternative human intervention.  Issue: May require redundant networking channel. Requires administrator or operator availability to
support.
Anticipating user disconnects and reconnects
Users must first be warned about the consequences of disconnection. Agents that provide protection for a disconnected session may become a nuisance for unsuspecting users if they fail to address protective measures in place for their safety. For example, users must know how much time they have to reconnect before safeguards take action. If a remote agent arms itself for application termination, users should be presented with a large, unmistakable disarming "opt-out" panel that, upon login and discovery, they can halt any agent actions before termination. Organizations should carefully discuss and publicize safety measures due to potential data loss.  Issue: Users should not be able to disable or specify their own timeouts due to potential irreversible
data loss.
General agent design guidelines
In developing an agent, HP recommends following these guidelines:  The agent should externally log its decisions and actions for postmortem analysis.  Independent agents should provide their own opt-out, disarming dialogs with countdown feedback
before taking action.  Where possible, limit your actions to those areas you are certain of the outcomes to minimize loss of
data and productivity.  Inspect error codes when reading event logs. The reliability of this HP ZCentral Remote Boost
communication method depends upon the Windows Event Log system. HP recommends using all information available to its fullest potential.
Recovery settings for the HP ZCentral Remote Boost Sender service
This section discusses restart options for HP ZCentral Remote Boost Sender and possible interactions of the agent with the sender. By default, most Windows services are installed without any automatic restart or recovery settings. The same is true for the HP ZCentral Remote Boost Sender service. Restarting the HP ZCentral Remote Boost Sender service can help reconnect a lost HP ZCentral Remote Boost connection (unless a system error prevents the HP ZCentral Remote Boost Sender service from restarting). When designing the agent, you should consider whether to check for the existence of a running HP ZCentral Remote Boost Sender service as an indication of a sufficient primary user connection. If service restarts are programmed for your environment, this test may be unnecessary.
Agent design guidelines 101

To set the HP ZCentral Remote Boost Sender service to restart automatically, you must change its recovery settings on the Recovery panel of its properties (right-click the service and select Properties). Actions to take for the first failure, second failure, and subsequent failures are available in the properties menu. The Recovery options include:  Take No Action  Restart the Service  Run a Program  Restart the Computer
Sample agent
The following sample Windows agent monitors the HPRemote event log and interprets its events. Comments are included in the agent code showing where additional code would be added to determine if the number of primary users has dropped to zero. If so, further code can be added to terminate applications on the sender. The sample code is a fixed-polling Windows agent that reads and interprets the HPRemote event log. The agent uses two functions: 1. processEvent(eventServer, eventSource, dwEventNum)

To properly use the function monitorEvents(...), the following strings must be defined in the function call:  LPCTSTR eventServer: if string is defined as "\\\\yourservername", then the log is stored on a remote server - if the string is empty (NULL), then the log is stored locally (note that four backlashes compiles to two in a string constant)  LPCTSTR eventSource: the name of the target event generator, for example, rgreceiver The sample agent uses Microsoft event logging functions such as OpenEventLog, ReadEventLog, and CloseEventLog. The sample agent is listed here. Where noted, add user-specific code . The agent header file, RGSenderEvents.h, is installed in the HP ZCentral Remote Boost Sender installation directory under the following path: \include\RGSenderEvents.h #include <windows.h> #include <stdio.h> #include "RGSenderEvents.h" #define BUFFER_SIZE 1024 // safe EVENTLOGRECORD size for now
