Use of SSH to connect to Linux servers
Since march 2001 it is no longer possible to use Telnet to connect to our Linux servers – in a world where the amount of hacker attacks are increased on a daily basis, is a program/protocol where username and password are send in clear text no longer an attractive solution when there are good encrypted alternatives. It will instead be possible to use the SSH programs/protocol, which in many ways works like Telnet.
To use SSH you need a terminal program with support of this protocol – check if your current terminal program has this feature (could be in the form of a plugin) or download a very good (and even free) terminal program here:
Must Linux users already have a SSH client installed which can be used through the normal console or X terminal (which ever one you prefer), but it could be an advantage to use a GUI on top of the ssh – we recommend one of the following:

MAC users that uses OS 9.x or earlier are not without hope – There is Nifty Telnet SSH, an excellent and free SSH capable terminal program, it can be found here:

The use of SSH is not much different from Telnet – you connect to the remote system with username and password as usual (we don’t support the use of RSA keys) and after the connection is established you have a normal shell on the remote system – the only difference is that every keystroke or data send or received are encrypted – and thus can’t be ‘sniffed’ by hackers.
