For Linux desktops, you can configure certain options by adding entries to the /etc/vmware/config file or the /etc/vmware/viewagent-custom.conf file.

During Horizon Agent installation, the installer copies two configuration template files, config.template and viewagent-custom.conf.template, to /etc/vmware. In addition, if /etc/vmware/config and /etc/vmware/viewagent-custom.conf do not exist, the installer copies config.template to config and viewagent-custom.conf.template to viewagent-custom.conf. All the configuration options are listed and documented in the configuration files. To set an option, remove the comment and change the value, as appropriate.

For example, the following line in /etc/vmware/config enables the build to lossless PNG mode. 
RemoteDisplay.buildToPNG=TRUE

After you make configuration changes, reboot Linux to make the changes take effect.

Configuration Options in /etc/vmware/config

The VMware BlastServer and BlastProxy processes, along with their related plug-ins and processes, use the /etc/vmware/config configuration file.
Note: The following table includes descriptions of each agent-enforced policy setting for USB devices in the Horizon Agent configuration file. Horizon Agent uses these settings to decide whether a USB device can be forwarded to the host machine. Horizon Agent also passes these settings to Horizon Client for interpretation and enforcement. The enforcement is based on whether you specify the merge ( (m)) modifier to apply the Horizon Agent filter policy setting in addition to the Horizon Client filter policy setting, or override the (o) modifier to use the Horizon Agent filter policy setting instead of the Horizon Client filter policy setting.
Table 1. Configuration Options in /etc/vmware/config
Option Value/Format Default Description
appScanner error, warn, info, or debug info

Use this option to specify the level of detail reported in the appScanner log file, which records activity related to remote application sessions. Valid values range from the least detailed "error" level to the most detailed "debug" level.

The appScanner log is located at /tmp/vmware-root/vmware-appScanner-<pid>.log, where <pid> is the ID of the appScanner process.
BlastProxy.log.logLevel error, warn, info, verbose, debug, or trace info

Use this option to specify the level of detail reported in the BlastProxy log file. Valid values range from the least detailed "error" level to the most detailed "trace" level.

The BlastProxy log is located at /tmp/vmware-root/vmware-BlastProxy-<pid>.log, where <pid> is the ID of the BlastProxy process.
BlastProxy.UdpEnabled true or false true Use this option to specify whether BlastProxy forwards UDP requests through secured port 22443 to Horizon Agent. true enables UDP forwarding. false deactivates UDP forwarding.
cdrserver.cacheEnable true or false true Set this option to enable or deactivate the write caching feature from the agent towards the client side.
cdrserver.customizedSharedFolderPath folder_path /home/ Use this option to change the client drive redirection shared folder location from the default /home/user/tsclient directory to a custom directory.

For example, if the user test wants to place the client drive redirection shared folder at /mnt/test/tsclient instead of /home/test/tsclient, the user can specify cdrserver.customizedSharedFolderPath=/mnt/.

Note: For this option to take effect, the specified folder must exist and be configured with the correct user permissions.
cdrserver.forcedByAdmin true or false false Set this option to control whether the client can share additional folders that are not specified with the cdrserver.shareFolders option.
cdrserver.logLevel error, warn, info, debug, trace, or verbose info Use this option to set the log level for the vmware-CDRserver.log file.
cdrserver.permissions R RW Use this option to apply additional read/write permissions that Horizon Agent has on the folders shared by Horizon Client. For example:
  • If the folder shared by Horizon Client has read and write permissions and you set cdrserver.permissions=R, then Horizon Agent has only read access permissions.
  • If the folder shared by Horizon Client has only read permissions and you set cdrserver.permissions=RW, Horizon Agent still has only read access rights. Horizon Agent cannot change the read only attribute set by Horizon Client. Horizon Agent can only remove the write access rights.
Typical uses are as follows:
  • cdrserver.permissions=R
  • #cdrserver.permissions=R (for example, comment it out or delete the entry)
cdrserver.sharedFolders file_path1,R;file-path2,; file_path3,R; ... undefined Specify one or more file paths to the folders that the client can share with the Linux desktop. For example:
  • For a Windows client: C:\spreadsheets,;D:\ebooks,R
  • For a non-Windows client: /tmp/spreadsheets;/tmp/ebooks,;/home/finance,R
Clipboard.Direction 0, 1, 2, or 3 2 Use this option to specify the clipboard redirection policy. Valid values are as follows:
  • 0 - Deactivate clipboard redirection.

Configuration Options in /etc/vmware/viewagent-custom.conf

Java Standalone Agent uses the configuration file /etc/vmware/viewagent-custom.conf.

Table 2. Configuration Options in /etc/vmware/viewagent-custom.conf
Option Value Default Description
CDREnable true or false true Use this option to enable or deactivate the client drive redirection feature.
CollaborationEnable true or false true Use this option to enable or deactivate the Session Collaboration feature on Linux desktops.
DPISyncEnable true or false true Set this option to enable or deactivate the DPI Synchronization feature, which ensures that the DPI setting in the remote desktop matches the client system's DPI setting.
EndpointVPNEnable true or false false Set this option to specify if the client's physical network card IP address or the VPN IP address is to be used when evaluating the endpoint IP address against the range of endpoint IP addresses used in the Dynamic Environment Manager Console. If the option is set to false, the client's physical network card IP address is used. Otherwise, the VPN IP address is used.
HelpDeskEnable true or false true Set this option to enable or deactivate the Help Desk Tool feature.
KeyboardLayoutSync true or false true Use this option to specify whether to synchronize a client's system locale list and current keyboard layout with Horizon Agent for Linux desktops.

When this setting is enabled or not configured, synchronization is allowed. When this setting is deactivated, synchronization is not allowed.

This feature is supported only for Horizon Client for Windows, and only for the English, French, German, Japanese, Korean, Spanish, Simplified Chinese, and Traditional Chinese locales.

LogCnt An integer -1 Use this option to set the reserved log file count in /tmp/vmware-root.
  • -1 - keep all
  • 0 - delete all
  • > 0 - reserved log count.
MaxSessionsBuffer

An integer between 1 and the value specified for Max Sessions Per RDS Host in the farm configuration wizard.

5 or 1

When configuring farms, use this option to specify the number of pre-launched sessions per host machine. When properly configured, this option can help speed the launch of desktop and application sessions.

The default value is 5 for non-vGPU farms, 1 for vGPU farms. A higher value means that more resources are pre-consumed in a vGPU or non-vGPU environment.

Configuring a high value is not recommended in a load-balanced vGPU environment that uses a lower vGPU profile because the high ratio of pre-consumed vGPU resources affects the behavior of the load balancer. For example, with a profile of 2Q in a load-balanced environment, using a high MaxSessionBuffer value can prevent the load balancer from assigning desktops and applications from that farm.

See Considerations for Linux Farms, Published Desktops, and Published Applications.
NetbiosDomain A text string, in all caps When configuring True SSO, use this option to set the NetBIOS name of your organization's domain.
OfflineJoinDomain pbis or samba pbis Use this option to set the instant-clone offline domain join. The available methods to perform an offline domain join are the PowerBroker Identity Services Open (PBISO) authentication and the Samba offline domain join. If this property has a value other than pbis or samba, the offline domain join is ignored.
RunOnceScript

Use this option to rejoin the cloned virtual machine to Active Directory.

Set the RunOnceScript option after the host name has changed. The specified script is run only once after the first host name change. The script is run with the root permission when the agent service starts and the host name has been changed since the agent installation.

For example, for the winbind solution, you must join the base virtual machine to Active Directory with winbind, and set this option to a script path. The script must contain the domain rejoin command /usr/bin/net ads join -U <ADUserName>%<ADUserPassword>. After VM Clone, the operating system customization changes the host name. When the agent service starts, the script executes to join the cloned virtual machine to Active Directory.

RunOnceScriptTimeout 120 Use this option to set the timeout time in seconds for the RunOnceScript option.

For example, set RunOnceScriptTimeout=120

SSLCiphers A text string !aNULL:kECDH+AESGCM:ECDH+AESGCM:RSA+AESGCM:kECDH+AES:ECDH+AES:RSA+AES Use this option to specify the list of ciphers. You must use the format that is defined by the OpenSSL standard. To find information about the OpenSSL-defined format, type these keywords into an Internet search engine: openssl cipher string.
SSLProtocols A text string TLSv1_1:TLSv1_2 Use this option to specify the security protocols. The supported protocols are TLSv1.1 and TLSv1.2.
SSODesktopType UseGnomeClassic or UseGnomeFlashback or UseGnomeUbuntu or UseMATE or UseKdePlasma N/A

This option specifies the desktop environment to use, instead of the default desktop environment, when SSO is enabled.

You must first ensure that the selected desktop environment is installed on your desktop before specifying to use it. After this option is set in an Ubuntu desktop, the option takes effect regardless if the SSO feature is enabled or not. If this option is specified in a RHEL/CentOS 7.x desktop, the selected desktop environment is used only if SSO is enabled.

Note: This option is not supported on RHEL/CentOS 8.x desktops. VMware Horizon supports only the Gnome desktop environment on RHEL/CentOS 8.x desktops.
SSOEnable true or false true Set this option to enable/deactivate single sign-on (SSO).
SSOUserFormat A text string [username] Use this option to specify the format of the login name for single sign-on. The default is the user name only. Set this option if the domain name is also required. Typically, the login name is the domain name plus a special character followed by the user name. If the special character is the backslash, you must escape it with another backslash. Examples of login name formats are as follows:
  • SSOUserFormat=[domain]\\[username]
  • SSOUserFormat=[domain]+[username]
  • SSOUserFormat=[username]@[domain]
Subnet A value in CIDR IP address format [subnet] Set this option to a subnet which other machines can use to connect to Horizon Agent for Linux. If there is more than one local IP address with different subnets, the local IP address in the configured subnet is used to connect to Horizon Agent for Linux. You must specify the value in the CIDR IP address format. For example, Subnet=123.456.7.8/24.
DEMEnable true or false false Set this option to enable or deactivate smart policies created in Dynamic Environment Manager. If the option is set to enable, and the condition in a smart policy is met, then the policy is enforced.
DEMNetworkPath A text string

This option must be set to the same network path that is set in the Dynamic Environment Manager Console. The path must be in the format similar to //10.111.22.333/view/LinuxAgent/DEMConfig.

The network path must correspond to a public, shared folder which does not require user name and password credentials for access.
Note: The VMwareBlastServer process uses the SSLCiphers, SSLProtocols, and SSLCipherServerPreference security options. When starting the VMwareBlastServer process, the Java Standalone Agent passes these options as parameters. When Blast Secure Gateway (BSG) is enabled, these options affect the connection between BSG and the Linux desktop. When BSG is disabled, these options affect the connection between the client and the Linux desktop.
