On Tuesday, November 27, 2007 SLAC will be converting to the newer more secure SSHv2 Protocol. So what does this mean for SLAC employees? The currently supported version of TeraTerm Pro which uses SSHv1 will no longer work to access SLAC systems.

TeraTerm Pro is a software terminal emulator that has been used at SLAC for several years to connect to UNIX systems from Windows systems. To meet DOE security regulations SCCS is moving away from TeraTerm Pro.

NOTE: On Tuesday, November 27, 2007 SLAC will be allowing only SSH version 2 connections to its Unix servers, and disallowing the older, insecure version 1 protocol. Both protocols are currently allowed, so you may switch your client software anytime before, November 27, the cutoff date.

To accommodate this new change, SCCS is recommending two new terminal emulators – PuTTY and SecureCRT. Information regarding the differences between these two programs can be found on the Pros and Cons page as well as the Client Comparison page. For more detailed information you can visit the vendor’s FAQ links listed on the Pros and Cons page.

Putty is a freeware application available to all users, while SecureCRT is currently only available to Stanford employees due to licensing restrictions.

Check the Client Downloads page for links to download and install the new software.

Additional information can be found at the SLAC Unix SSH website.

Secure Shell or SSH is a network protocol that allows data to be exchanged over a secure channel between two computers.

SSH is typically used to log into a remote machine and execute commands, but it also supports tunneling, forwarding arbitrary TCP ports and X11 connections; it can transfer files using the associated SFTP or SCP protocols.
