Many students and faculty find it useful to access the College's UNIX resources from a remote host, such as from their dorm room or from a computer in their home or apartment off-campus. Doing so may require up to three pieces of software. The first is a secure shell (ssh) client; having this will allow you to do anything you would normally do from the command line (in a "terminal window"). If you also need to be able to see graphics (such as the graphical user interface of a piece of software, or plots from Matlab, etc.), you will also need an X Windows server.
If you have Linux or a UNIX variant on your PC, or if you're using Mac OS X, you should already have both an ssh client and a X server; consult the documentation if you don't know how to use them.
If you are using a Windows PC, you can get a copy of SSH Secure Shell for Windows (we have a free installer for academic use), or you can use the popular free client called putty. For an X Server, the College has a license for X Win-32. You can also try the free Xming software. Installers for SSH and X Win 32 are both available from the Remote Access Download page, which you can access with your campus username and password.
The third piece of software is the VPN client. Many of our UNIX/Linux machines are not directly accessible from off-campus. Having the VPN client running on your machine makes your computer appear to be on-campus. The VPN Client for the University is available from CaTS.
After you have the software, you'll probably want to set up your ssh client to tunnel the X connection. If you don't want to do this, then you'll need to determine the IP address of your system, and set your DISPLAY environment variable accordingly.
All you need to do, then, is ssh to your chosen UNIX system (either one of the College systems or unixapps1), set your DISPLAY environment variable, if necessary, and run your program.
