sss_ssh_knownhosts(1)

When the keys retrieved from the backend do not include the hostname, this tool will add the unmodified hostname as provided by the caller. If this flag is set, only the hostname (no port number) will be added to the keys.

.SH "KEY RETRIEVAL"

.PP The key lines retrieved from the backend are expected to respect the key format as described in the “SSH_KNOWN_HOSTS FILE FORMAT” section of sshd(8). However, returning only the keytype and the key itself is tolerated, in which case, the hostname received as parameter will be added before the keytype to output a correctly formatted line. The hostname will be added unmodified or just the hostname (no port number), depending on whether the -o,--only-host-name option was provided.

.PP When the SSH server is listening on a non-default port, the backend MUST provide the hostname including the port number in the correct format and position as part of the key line. For example, the minimal key line would be:

                [canonical.host.name]:2222 <keytype> <base64-encoded key>


            

.SH "EXIT STATUS"

.PP In case of successful execution, even if no key was found for that host or if the ssh responder could not be contacted, 0 is returned. 1 is returned in case of any other error.
