Updating SSH Host Key Information

Typically, SSH host key information is automatically retrieved when you set a URL attribute for SCP using the archival configuration archive-sites statement at the [edit system] hierarchy level. However, if you need to manually update the host key database, use one of the following methods.

Retrieving Host Key Information Manually

To manually retrieve SSH public host key information, use the fetch-from-server option with the set security ssh-known-hosts command. You must include a hostname attribute with the set security ssh-known-hosts fetch-from-server command to specify the host from which to retrieve the SSH public key.

Importing Host Key Information from a File

To manually import SSH host key information from the known-hosts file located at /var/tmp/known-hosts on the server, include the load-key-file option with the set security ssh-known-hosts command. You must include the path to the known-hosts file with the set security ssh-known-hosts load-key-file command to specify the location from which to import host key information.
