You can configure certain options by adding entries to the files /etc/vmware/config or /etc/vmware/viewagent-custom.conf.
During the installation of Horizon Agent, 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. In the template files, all the configuration options are listed and documented. To set an option, simply 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 for the changes to take effect.
Configuration Options in /etc/vmware/config
VMwareBlastServer and its related plug-ins use the configuration file
/etc/vmware/config.
Note: The following table includes description for each agent-enforced policy setting for USB in the
Horizon Agent configuration file.
Horizon Agent uses the settings to decide if a USB can be forwarded to the host machine.
Horizon Agent also passes the 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.

Example: m:vid-0f0f_pid-55** |
| viewusb.SplitVidPid | {m|o}: vid-xxxx_pid-yyyy([exintf:zz[;exintf:ww]])[;...] | undefined | Set this option to treat the components of a composite USB device specified by Vendor and Product IDs as separate devices. The format of the setting is vid-xxxx_pid-yyyy(exintf:zz[;exintf:ww]). You can use the exintf keyword to exclude components from redirection by specifying their interface number. You must specify ID numbers in hexadecimal, and interface numbers in decimal including any leading zero. You can use the wildcard character (*) in place of individual digits in an ID. Example: o:vid-0f0f_pid-***(exintf-01);vid-0781_pid-554c(exintf:01;exintf:02)
Note: Horizon does not automatically include the components that you have not explicitly excluded. You must specify a filter policy such as
Include VidPid Device to include those components.

Configuration Options in /etc/vmware/viewagent-custom.conf
Java Standalone Agent uses the configuration file /etc/vmware/viewagent-custom.conf.
| Option | Value | Default | Description |
|---|---|---|---|
| CDREnable | true or false | true | Use this option to enable or disable the Client Drive Redirection (CDR) feature. |
| CollaborationEnable | true or false | true | Use this option to enable or disable the Session Collaboration feature on Linux desktops. |
| 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 disable 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 disabled, 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.
|
| 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 is run 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 |
|
| 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 in https://www.openssl.org/docs/manmaster/man1/ciphers.html. |
| SSLProtocols | A text string | TLSv1_1:TLSv1_2 | Use this option to specify the security protocols. The supported protocols are TLSv1.0, 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. This option is not supported on RHEL/CentOS 8.x and RHEL/CentOS 6.x desktops. Horizon 7 only supports the Gnome desktop environment on RHEL/CentOS 8.x desktops. |
| SSOEnable | true or false | true | Set this option to enable/disable 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:
|
| Subnet | A value in CIDR IP address format | [subnet] | Set this option to a subnet which other machines can use to connect to the 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 for connecting to the Horizon Agent for Linux. You must specify the value in the CIDR IP address format. For example, Subnet=123.456.7.8/24. |
| UEMEnable | true or false | false | Set this option to enable or disable Dynamic Environment Manager smart policies. If the option is set to enable, and the condition in the Dynamic Environment Manager smart policy is met, then the policies are enforced. |
| UEMNetworkPath | A text string | This option must be set to the same network path that is set in Dynamic Environment Manager Console. The path must be in the format similar to //10.111.22.333/view/LinuxAgent/UEMConfig. |
Note: The three security options, SSLCiphers, SSLProtocols, and SSLCipherServerPreference are for the VMwareBlastServer process. 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.
