      I am using it with great success.

    I'll try anything once. In fact, I tried
      twice. It can't set up.

      First, the code has port 22 baked in. I mentioned earlier that my
      sshd listens on a nonstandard port.

      Looking at the code (gluster_georep_tools/setup/cli.py,
      glustercli/cli/georep.py), there is provision within functions for
      a different port, but there is no way that I see to use that in
      command line args.

      Oddly shortsighted, or maybe I'm missing something.

      So second, I tweaked the code to use my nonstandard port as its
      default, replacing all "22" with mine, and tried again...nope.

    Geo-replication session will be established
      between j and geoacct@pms::n

      root@pms password is required to complete the setup. NOTE:
      Password will not be stored.

      root@pms's password: 

      [    OK] pms is Reachable(Port 6247)

      Traceback (most recent call last):

      paramiko.ssh_exception.NoValidConnectionsError: [Errno None]
      Unable to connect to port 22 on 172.17.4.3

    It seems that paramiko is either still using
      22 under the hood somewhere (cf.
      last line error), or 22 is misinfo
      but it's insisting on connection using a password, but my
      (otherwise pretty standard) sshd configuration requires keys-only
      root login, no password, which is already in place among all these
      machines.

      I'm open to other suggestions.
