On April 27, 2001, Cray IS will be disabling the incoming 'telnet' service on all machines accessible from outside of the Cray network. At that time, we will provide 'ssh' access as the main method for connection to all machines outside of the Cray firewall. This is being done in an attempt to increase network security, as well as advocate use of the many added features that 'ssh' provides over 'telnet'.
If you are currently using telnet as your external connection method, please read all the following information. While the telnet service will not be turned off for a while, it is recommended that you download and begin using a 'ssh' client now to provide more time to familiarize yourself with the software.

OpenSSH can be compiled for most versions of Unix. To begin building the Unix version of OpenSSH from the source, you can use the following packages.
I compiled the above sources, and the IRIX 6.5 executables for the ssh and scp commands are available. slogin can be created as a link to ssh (ln -s ssh slogin).
