SSH support

[cmccluskey]

In our application for controlling our APC units we need to use SSH instead of Telnet. I think Paramiko or similar can be easily replace the Telnet in your current implementation, but does mean including of some heavy modules to support this. Any interest in including this?

Ideally it should be an optional dependency

Maybe https://github.com/fgimian/paramiko-expect should be considered

For interacting with telnet, pexpect is used

What is important (too me) is to have code that works with telnet and (if optional depencies are necessary and installed) works with ssh

I haven't test it mysef, but did you tried to pass cli parameter

parser.add_argument('--cli', action='store', default='',
                    help="command line to execute 'ssh {user}@{host}' or 'telnet {host}")

See also class APCFactory

Contributions are welcome

I will give the cli argument a try. I think the only hangup then would be that the keys would then have to be published in the known_hosts file beforehand (something that paramiko handles very nicely for new/unknown entries).

The paramiko-exspect would be a nice way to glue the SSH side to use the same code as the telnet side since the send/expect calls appear to be the same at first glance.

I'll post what I discover.

Hello Cmccluskey,

I used the script and also would like to change telnet to ssh, but when I changed utility.py line 72 from "commandline = 'telnet %s' % host" to " commandline = 'ssh %s' % host" and tried running but got error:

apc --status

Acquiring lock /tmp/apc.lock
Connecting to APC @ 192.168.21.87
ERROR: Timeout connecting to APC

I think maybe the commandline is error, do you know how to change the commandline to ssh?

Thank you so much.
