Users of UNIX Servers ux5, ux8 Will Need to Use SSH for Logging In

Lab employees who log into central UNIX servers ux5 and ux8, used primarily for publishing Web pages, will no longer be able to log in using the "telnet" application. Beginning Friday, Sept. 1, access will be allowed only using the more secure SSH application. Users can still use their same logins and passwords. The changes won't affect those employees who use the FTP (file transfer protocol) to update Web pages.

The switch is part of the Lab's efforts to increase cyber-security. Unlike "telnet," SSH (for Secure Shell), encrypts network data communications end-to-end and is now being adopted as the Lab standard. The Lab has purchased a site-wide license for F-Secure SSH, a commercial version of the application.
