When using SSH to communicate with InCenter, an SSH server internal to InCenter is being used. The server host key used is a 2048 bit RSA key and is automatically generated during initial system startup. This SSH server can be managed using the sshserver command.

Viewing SSH Server Status and the Current Key

Using the -showkey option with the sshserver command will display both the current status of the SSH server and the current key:

admin@InCenter:/> sshserver -showkey
SSH server status: running
Public Key:

Changing the SSH Server Key

Using the -keygen option with the sshserver command will generate a new key for the server. The system will prompt the administrator to check that the action should be completed:

admin@InCenter:/> sshserver -keygen
This action will generate a new host key to the ssh server.
For this to take effect the ssh server needs to be restarted
and your current ssh session will end
