The LoadMaster host key that is used for SSH login can now be regenerated using controls on the system console. Log into the console and choose Local Administration > Regenerate SSH Host Keys to regenerate the key. Please note the following:

  • When you regenerate the LoadMaster's host key, all current SSH clients will need to be updated with the new public key. Clients will receive connection errors and be unable to connect until the new public key is added to the client's known_hosts file.
  • When LoadMaster is configured in either the High Availability or Clustering modes, the host keys on the two LoadMasters are automatically synchronized to maintain the SSH connection on which the configuration depends.
  • Note that in GEO Partnering mode, SSH host keys are not automatically synchronized, because GEO does not use a shared IP address and the information exchange between partners doesn't depend on SSH access.
