I figured maybe we could make a thread of useful commands you know/use.

Here's a good one to start with:

If you want to see ip addresses connected via ssh type:

echo $SSH_CLIENT | awk '{ print $1 }'

You can also just type pinky and it will give you the username, full name, time, and ip address of the connected users.
