Description Nate Straz 2016-06-03 15:15:46 UTC
Description of problem:

Sometimes when getting the status of a power outlet using the fence_apc fencing agent, the command will fail with "Connection timed out."

Turning on verbose shows:

Sent: ^C
Connection timed out

The ^C to get back to the top menu isn't being seen by the APC at the right time.  The top menu doesn't get displayed and the fence agent sits there waiting until the time out expires.

If I wait for the command prompt after the loop, the fence agent doesn't time out there.

                 if exp_result != 0:
+        conn.log_expect(options, options["--command-prompt"], int(options["--shell-timeout"]))
         conn.log_expect(options, "- Logout", int(options["--shell-timeout"]))
