Setting up "Call Home" on CMS6100 or VCMS
The CMS6100 or VCMS central management appliance (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 them).
For "Remote Console Servers" (i.e. console servers that are firewalled, not routable, or otherwise unreachable from the CMS) these SSH connections are initiated by the Managed Console Server via an initial Call Home connection.
To configure for Call Home on the CMS:
- The first step is to enter a Call Home Password on the Configure: System Administration screen. This password is used solely for a system account for accepting Call Home connections. The current Call Home Password will be required by console servers looking to register as candidates to be managed. However it is safe to change this password at any stage, without affecting currently established Call Home connections.
- Select Configure: Managed Console Servers.
The Managed Console Servers list displays all the console servers which are currently being monitored by the CMS:
- The Host Last Retrieved field shows when the configuration information (such as user and Managed Device details, alert settings etc) was last updated in the CMS. These can be updated by clicking Retrieve Hosts
- The IP Address/DNS Name shows how the CMS is accessing this Managed Console Server. For a Remote Console Server (i.e. those connected using Call Home) this shows the local redirected port, and the remote IP address from which the connection has originated. The local redirected port matches the Listening Port as displayed in the Call Home connection on the Remote Console Server.
The Detected Console Servers list displays all the console servers which are currently not being monitored by the CMS:
- The Remote Console Servers list shows all the console servers that have established a Call Home connection (so are candidates) but and are not currently being monitored
- Refer faq373- How to set up Call Home on console server
- When adding a (Detected) Remote Console Server, the IP Address will appear as localhost. This is the loopback listening port created by the Call Home connection
- To add a console server to the Managed Console Servers list, select it from the (Detected) Remote Console Servers drop down list, and click Add
- Enter the IP Address and SSH Port if these fields have not been auto-completed
- Enter a Description and unique Name for the Managed Console Server you are adding (e.g. “Boston”)
- Enter the Remote Root Password (i.e. System Password that has been set on this Managed Console Server). This password is used by the CMS to propagate auto generated SSH keys and then forgotten. This password will not be stored
- Click Apply
The CMS will now set up secure SSH connections to and from the Managed Console Server. “Boston” will be included in the Managed Console Servers list (which displays all the console servers which are currently being monitored by the CMS). And the CMS will retrieve its Managed Devices, user account details and configured alerts.
