Secure Shell

[edit]
Using Secure Shell (SSH)
Secure Shell is similar telnet, but much more secure. It allows a user to remotely log into another GUN/Linux computer and do tasks as needed. In the past, using ssh to log into a Astronomy Linux computer from another one was needed because at the time, there was not a centralized drive to hold all the astronomy data. There is not so much a a need anymore, however, here is how to do it.
If a user with the username tux, wants to ssh to timelord, at a command prompt, type:
ssh tux@timelord.byu.edu
The user will be prompted for a password. This will log in and it will be as if you are are at the command line terminal on timelord.
If you want to be able to open programs that use a graphical interface such as firefox, at a command prompt, type:
ssh -Y tux@timelord.byu.edu
