I'm looking for a way to create a VNC console user that executes the command screen
or bash
immediately after logging in so they get their own restricted shell for executing commands etc. Screen/bash will be pre-configured to handle all security issues. The VNC console also has to terminate once the user types the exit/logout command as I don't want them to access the rest of the system.
I have already looked through the documentation of TigerVNC and TightVNC but couldn't find anything useful.
If this is not possible with VNC, a SSH console can work as well.
The server's OS is CentOS.
