When a remote user starts a published application or desktop, a set of session variables is created by Parallels RAS on the host server. The variables contain information about the client machine, which you can examine if needed. The variables are always updated, so on connect/reconnect they always contain the latest values.
The following RAS session variables are available:
You can view RAS session variables and their values using one of the following two methods:
By examining the Windows registry on the host server.
By executing the GetRASVariable.exe utility (provided by Parallels RAS).
Each method is described below.
To see the variables, run regedit
and navigate to HKEY_CURRENT_USER\Software\Parallels\Shell\<Session-ID>
, where <Session-ID> is the ID of a session as displayed in the RAS Console (e.g. 2, 3, 4, etc.) The variables for a particular session are listed under the session ID node. On user connect/reconnect they are updated to reflect the actual client configuration. The variables exist for the duration of a session and are removed from the registry once the session is terminated.
Please note that in addition to the variables listed in the table above you may see other (undocumented) variables under a session ID. Those are for internal Parallels RAS use only and should be ignored.
The GetRASVariable.exe utility is located in the Parallels RAS installation folder (e.g. C:\Program Files (x86)\Parallels\ApplicationServer). To obtain a value of a variable, execute the utility from the command line passing the variable name as parameter (see the table above). The utility will output the value to the screen.
The following example displays the value of the TUX_REMOTECLIENT_MACHINE variable:
GetRASVariable.exe TUX_REMOTECLIENT_MACHINE
TUX_REMOTECLIENT_PLATFORM
Name and version of the operating system running on the client machine. For example, "Windows 8.1 Enterprise Edition (WOW 64)", "iPhone OS 9.2.1", "Android 6.0", etc.
TUX_REMOTECLIENT_MAC
MAC address of the client machine.
TUX_REMOTECLIENT_IP
IP address of the client machine as seen by the client.
TUX_REMOTECLIENT_LANG
Language used by the GUI on the client machine: EN, FR, RU, DE, ES, IT, PT, NL, JP, CS (Chinese Simplified), CT (Chinese Traditional), KR (Korean).
Note that on macOS, iOS, and Android devices, the language is reported as the one used in the OS but only if it's a supported language. If it's not supported, it will default to EN.
TUX_REMOTECLIENT_MACHINE
Client's computer name. For example, "Bob's iPad mini 1st generation", "BobPC", "Bob's iMac", etc.
TUX_REMOTECLIENT_LOGIN
The username (including domain) that was used to log in to Parallels RAS. For example, myuser@somedomain.
TUX_REMOTECLIENT_VERSION
Parallels Client version.
TUX_REMOTECLIENT_VENDOR
Device vendor name. For example, "Asus", "Apple", "Google", etc.
TUX_REMOTECLIENT_MODEL
Device model name. For example, "Nexus 5", "iPad2.6", etc.
