Find the IP address of the client in an SSH session
Check if there is an environment variable called:
$SSH_CLIENT OR
$SSH_CONNECTION(or any other environment variables) which gets set when the user logs in. Then process it using the user login script.
Extract the IP:
$ echo $SSH_CLIENT | awk '{ print $1}'1.2.3.4$ echo $SSH_CONNECTION | awk '{print $1}'1.2.3.4
You could use the command:
server:~# pinkythat will give to you somehting like this:
Login Name TTY Idle When Where root root pts/0 2009-06-15 13:41 192.168.1.133
Try the following to get just the IP address:
who am i|awk '{ print $5}'
