Improving your online security - Use SSH instead of Telnet

To further promote online security, the use of telnet to make inbound connections to the University network was replaced recently. Telnet sends account names and passwords in the clear text, allowing anyone who can see the traffic to pick out the information, a process known as “sniffing.”


A much more secure method, known as SSH, or Secure Shell, is the recommended alternative to Telnet. It protects account names and passwords by encrypting them before transmission. The University has licensed a version of SSH for use on its machines in the Mathews General Purpose Lab. Instructions on using the campus SSH client can be found here.


If you are working form home and do not have SSH, it can be downloaded. Download SSH


There are other free clients available from the Internet, such as PuTTY and OpenSSH.
