  • 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
