Secure Shell or SSH provides encrypted connections between untrusted hosts over an insecure network.  The SGI supercomputers can be accessed using SSH from the hosts inside UConn.

For Windows systems, Putty is a popular free ssh client program. WinSCP is a free sftp/scp program for file transfer. More information regarding how to use Putty and WinSCP can be found in FAQs.

OpenSSH is a free SSH program available on many Linux/UNIX platforms.

To log in using openssh:   
    ssh -l login_name sgi1.engr.uconn.edu
    ssh -l login_name +X sgi1.engr.uconn.edu (Enabling X11 forwarding)
To transfer files using sftp:
    sftp login_name@sgi1.engr.uconn.edu

If you need to run programs with GUI on the supercomputers and have the display on your local computer,  a X server program is required . X server support is already integrated in most Linux/UNIX/BSD systems. For Win32 systems, Cygwin/X is a port of the X Window System to the Microsoft Windows. Check here for more information regarding Cygwin/X. There are also many commercial X-Window programs for Win32 platforms, e.g. X-Win32 and Hummingbird Exceed.
