Want to make a script that checks connection protocol
Hello all,

I currently connect to several servers multiple times a day. Most of the time I connect via SSH through the terminal emulator poderosa (my personal favorite), but sometimes I connect via telnet through xstart because I need it to export a GUI.

What I want to do is add something to my bashrc that will check the connection method and if it's ssh take me directly to the command line, but if it's telnet execute the command that exports the GUI (admincon).

I'm sure I can handle the scripting side of it (even if it is my general level of inelegance...) but I don't know how to check for connection protocol.

Any suggestions?

One option would be to check the parents process(es) using ps to determine whether your shell was launched by sshd or inetd (most likely in the case of telnet).

check for the existence of the $SSH_CONNECTION variable

Yep, that's a better idea.
