SSH Protocol

Connecting to Linux computers usually requires communications software that can use the ssh protocol. This enables encrypted communications between your computer and the remote site.

Many systems (Mac OS X, Linux and UNIX variants) have the ssh command that allows connections built into their command line interfaces. The general format of the command is:

ssh username@ComputerName.usask.ca
MicroSoft Windows

There are several ssh client programs that can be downloaded for Windows, but we recommend PuTTY. For Windows file transfer to Linux computers, we recommend WinSCP.

X11 Graphics 

An additional note for MicroSoft Windows users is that the Linux clusters use the X11 windows system protocol for graphical displays. While this is supported natively under Linux and MacOS X, Windows users will need an X11 server to run on their computers. One freely available system is Xming. (The MESA download is recommended.)

If the Xming version does not fulfill your needs, an alternative environment is Cygwin/X - a Linux like experience with a newer X11 server.

You will likely need to permit the X11 server to accept connections in the Windows firewall.

PuTTY users can easily set up an automatic connection to their X11 server  through the session settings under Configuration. An example of how this is set is shown below.
