Since each has it own set of strengths, weakness, and features, we are supporting both. SSH is free for almost all versions of Unix and can be downloaded here . See the SSH home page for more information on the program. Also see the SSH suggestions and contact us if you need assistance. It provides strong authentication and secure communications over insecure channels.
All communications are automatically and transparently encrypted.
Encryption is also used to protect against spoofed packets and hijacked connections. X11 connection forwarding provides secure X11 sessions. An authentication agent, running in the user's local workstation or laptop, can be used to hold the user's RSA authentication keys. Multiple convenience features fix annoying problems with rlogin and rsh. Ssh is intended as a complete replacement for rlogin, rsh, rcp, and rdist and can also replace telnet.
