SSH From Behind the Firewall

We've just got a network connection at the college where the boys do music.  Unfortunately the firewall blocks ssh traffic.  In order to get round this I've set up the ssh daemon to listen on port 443 and that gets round the firewall.

Here's the steps:

1. sudo vi /etc/ssh/sshd_config
2. Add in the line Port 443
3. sudo /etc/init.d/sshd restart
