Secure Shell (SSH) Software

The department has moved away from unsecured telnet and ftp connections to the secure connectivity provided by SSH. Secure Shell (SSH) is a network protocol used by many application programs. SSH allows data to be exchanged over a network using a secure channel. It is used as a replacement for ftp, rcp, rexec, rlogin, rsh and telnet.

Our central timesharing systems are running SSH, protocol v 3.0. SSH, protocol v 2.x will also connect to these systems. Users are advised to obtain a copy of an SSH client program (e.g., PuTTY) for remote login/shell connections, and a copy of a secure file transfer program (e.g., WinSCP).

The central campus computing center, UITS, has a download page which lists a number of recommended SSH client applications.


For Mac users running any version of Mac OS X, the ssh/scp/sftp tools are built-in and available via the command line within the Terminal application. The Terminal application is available in Mac OS X in the /Applications/Utilities directory in Finder.

For information on using Secure Socket Layers (SSL) with department supported mail readers, see Thunderbird E-mail Settings or Pine E-mail Settings.
