The default host SSH keys used in a InCenter Linux system are always unique. However, there may be a need to set the keys to particular values. For example, this need can arise in a InCenter redundancy cluster where they are not synced automatically and where the keys on all nodes should be manually set to the same values to avoid warning messages from the management client.

Changing the keys is done by overwriting the SSH key files using SCP. These files are found in the Linux folder /home/administrator/mgmtsystem/ and they must be given the same names when they are replaced. These names are always host_rsa and host_rsa.pub.

For example, a typical SCP command to upload and overwrite the host_rsa file might be the following:

> scp -P 2222 host_rsa
	administrator@198.0.2.10:/home/administrator/mgmtsystem 

Once the host SSH files are replaced, the InCenter system must be restarted.
