Connect to PDU timeout

[smallfish01]

Hello,
I use the script try to connect my APC PDU, when I running: apc --status and got the error:

apc --status

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

In this case, I changed utility.py line 72, changed telnet to ssh, looks my ssh parameter error? If I need change telnet to ssh, how is the command line? Also I'd like to know how can I change the value of timeout?

Thank you.
