About SSH
Secure Shell (SSH) is both a computer program and an associated network protocol that you
use to log in to and run commands on a networked computer. SSH provides secure encrypted
communications between two untrusted hosts over an insecure network. Avaya strongly
recommends that you use SSH instead of Telnet for most interactive connections to the Avaya
media servers and other devices on a customer network.
To use SSH, a third-party SSH client must be installed on your computer. PuTTY is one such
client. You can download PuTTY from
