Hi Linux Newbie, Theres a few ways of doing this. - You can run a command by adding it to the command line when calling ssh. ie. ssh <host> "command" - If you're using keys instead of password authentication you can force the server to invoke a command by adding "command=<command>" before the user's key in the .ssh/authorized_keys file - In sshd_config you can add the line "ForceCommand <command>". You can wrap this in a "Match" conditional block - Alter the server-side user's profile or the system-wide profile to invoke a command upon logging in.
