The SSH protocol provides a secure tunnel for connecting to remote
servers. All information -- including your username and password -- is
encrypted. You will need a SSH Client to connect to your shell
account, and the following information:
Hostname: UL.net
Port: 22
SSH for Windows
A good, free SSH client for Windows can be obtained from
http://www.chiark.greenend.org.uk/~sgtatham/putty/.
SSH for MacOS
NiftySSH is a good SSH client for those who use the Mac. Information
is available at
http://www.lysator.liu.se/~jonasw/freeware/niftyssh/.
Also, http://www.macssh.com/ is another
good choice.
SSH for Unix / Linux
Nearly every modern version of Unix includes a SSH client. The usual
command syntax goes something like this:
ssh username@UL.net
If you do not have ssh installed, a very good, free implementation
called OpenSSH can be obtained from http://www.openssh.com.
