Running Commands before or after a Session

Symptom

You want to run shell commands before a specific session is started or after it has terminated.

Problem

You need hooks which will call your shell commands.

Solution

As of IGEL Universal Desktop Linux 5.06.100 there is a generic mechanism for calling shell commands before and after a session. It works with Citrix ICA, RDP and VNC Viewer sessions.

This feature is accessible only through the Registry.

Open Setup at System > Registry. Use either the Registry tree or the Search parameter ... function to locate the following Registry keys:

for VNCviewer:

sessions.vncviewer*.init_action

sessions.vncviewer*.final_action

for RDP:

sessions.winconnect*.init_action

sessions.winconnect*.final_action

for Citrix/ICA:

sessions.ica*.init_action

sessions.ica*.final_action

(where * is the related session number, e.g. 0,1,2,3,...)

The init_action is executed before the session is started. The final_action is executed after the session has been terminated. Enter shell commands or the path to a custom script or executable:

Configuring the Init Action

The Registry keys for newly created sessions only appear after a restart of Setup.

Your init_action scripts or executables have to return before the session will start. Alternatively, background your command by adding '&' to the end of the commandline.
