keys (sequence of tuple; (string, string, string)) - Keys to write, tuples consist of key type (constants.SSHK_ALL), public and private key
dry_run (boolean) - Whether to perform a dry run
keyfiles (dict; (string as key, tuple with (string, string) as values)) - Mapping from key types (constants.SSHK_ALL) to file names; value tuples consist of public key filename and private key filename

UpdateSshDaemon(data, dry_run, _runcmd_fn=utils.RunCmd, _keyfiles=None)

source code

Updates SSH daemon's keys.

Unless dry_run is set, the daemon is restarted at the end.
