What is going on here with the %% * ?

It's a bash string operation that removes a suffix. In this case everything (*) following the first space in the variable $SSH_CLIENT - which looks like: "192.168.178.1 45721 22". So what is left is the ip. From "man bash": {parameter%%word} Remove matching suffix pattern.
