Our Debian-GNU/Linux servers

All our servers now support SECURE SHELL which makes it possible to connect to them in a way that protects against spoofing (somebody only pretending to be the machine you think you are connected to), sniffing (somebody listening in to your session and e.g. the passwords you type during it), and hi-jacking (somebody taking over your session while you think the net is once again down).
