Console Server & RIM Gateway User Manual
4.12 Call Home
All console servers with Firmware V3.2 and later, include the Call Home feature which initiates the setup of a secure SSH
tunnel from the console server to a centralized CMS6100 or VCMS server (referred to herein as CMS ). The console
server
then registers as a “candidate” on the
CMS - and once accepted there it becomes a Managed Console Server .
The CMS will then monitor the Managed Console Server, and administrators can access the remote Managed Console
Server, through the
CMS. This access is available even when the remote console server is behind a third party firewall or
has a private non-routable IP addresses (which is often the case when the console server is connected via a cellular
modem connection).
Note CMS maintains public key authenticated SSH connections to each of its Managed Console Servers. These
connections are used for monitoring, commanding and accessing the Managed Console Servers and the
Managed Devices connected to the Managed Console Server.
To manage Local Console Servers, or console servers that are reachable from the CMS , the SSH connections
are initiated by CMS .
To manage Remote Console Servers, or console servers that are firewalled, not routable, or otherwise
unreachable from the
CMS , the SSH connections are initiated by the Managed Console Server via an initial Call
Home connection.
This ensures secure, authenticated communications and enables Managed Console Servers units to be
distributed locally on a LAN, or remotely around the world.
