SSH stands for "Secure Shell", it is one of the easier ways to connect to a machine at UCC, because physically standing up and going over to one is difficult.
Connecting
1. Download and install a SSH client for your OS:
Windows: PuTTy/KiTTY - http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html
Linux: OpenSSH
2. Find the details of the server you wish to connect to (most of the time will be Motsugo [ssh.ucc.asn.au::22]).
3. Enter them into your client: PuTTY/KiTTY: Host name should be the address of the server, Port will default to 22, which is fine. OpenSSH: "ssh ssh.ucc.asn.au", then say yes to the prompt regarding known_hosts, assuming you trust us.
4. Enter your UCC username and password
