Chapter 1: Introduction
22 Installing and Configuring the Avaya S8400 Media Server February 2006
About SSH
Secure Shell (SSH) is both a computer program and an associated network protocol designed
for logging into and executing commands on a networked computer. SSH provides secure
encrypted communications between two untrusted hosts over an insecure network. Avaya
recommends using SSH instead of Telnet for most interactive connections to the Avaya media
servers and other devices on a customer’s network.
To use SSH, a third-party SSH client must be installed on your computer. PuTTY is one such
client available for download from http://www.putty.nl/download.html
.
Devices that can be accessed with SSH include:
● Media servers on Release 3.1 of Communication Manager: S8300, S8400, S8500,
S8700-series
May include port number reference 5022 for direct SAT access.
● Server Availability Management Processor (SAMP) (used with S8500 Media Server)
May include port number reference 10022 for direct access
● Maintenance Processor Complex (MPC) (used with S8400 Media Server)
May include port number reference 10022 for direct access
● TN2312BP IPSI running firmware version 20 or higher
● TN8412AP SIPI
● TN2602 IP Media Resource 360 running firmware version 212 or higher
● Expanded Meet-Me Conferencing (EMMC) and the S6100 Media Server
● SIP server
● G250 and G350 media gateways
● C360 Ethernet switches
!
Important:
Important: G700 does not allow the use of SSH. From within a media server's Linux
command line, you can use SSH to access the G250 and G350, but you must use
telnet to access the G700. In this case, the server is the SSH client, not PuTTY.
