SSH programs exist for all major operating systems - Windows, Mac, and Linux. Mac OS X and Linux come with these commands built -ininto the Terminal application; Windows needs some help. If you're using a Windows system and are part of UT Austin, Bevoware provides two free SSH programs, "SSH secure clientSecure Shell" and "PuTTY," and either one will work.  If not part of UT Austin, a simple Google search for "SSH Secure Shell 3.2.9" should return a number of download links.

To SSH into a remote computer, you need it's location and a set of login credentials.  For Lonestar, here is the information:

Panel

Host:lonestar.tacc.utexas.

...

edu
Port: 22 (the default)
Username:(the same username you use to login to portal.tacc.utexas.edu)

Usually Windows users will need to type this information into separate boxes.  Mac OS X and Linux users can just type it straight into the Terminal.  Let's try it now by entering this:

Code Block
titleSSH to access Lonestar at TACC
ssh <your TACC user ID>@lonestar.tacc.utexas.edu

When prompted, type in your password.  It won't show your password on the screen, but when you press Enter, it will either accept the password or ask for it again.

When you log in to a Linux computer, the operating system checks your login credentials and if they're OK it sets up some configuration for you and then runs a program called a "shell" which acts like your fast-food drive-thru window to the rest of the operating system. You type commands and hit "enter" to send something into the drive-thru window, and then the OS passes output back through the drive-thru window.
