Does 'fence_apc_snmp -a hac-pdu1 -n 1 -o status' work? What about
'fence_apc -a hac-pdu1 -l <user> -p <passwd> -n 1 -o status'?

All,
I have a bigger issue regarding dual power supplies and fence_apc that I'm going to eventually need to resolve. But at this point I'm simply having basic issues getting the fence_apc agent to be able to access the devices in general, to wit:
# fence_apc --ssh --ip=hac-pdu1 --plug=1 --username=blah --password=blah --verbose --action=status
Unable to connect/login to fencing device
However I can manually SSH into the device just fine:
# ssh blah@hac-pdu1
blah@hac-pdu1's password:

So perhaps the place to start first is simply getting the fence_apc agent (provided by CentOS/RHEL package fence-agents-3.1.5-35.el6_5.3.x86_64) to actually be able to work correctly. Once that's done, I'll still need help on the dual power supply issue.
I'm not seeing any attempts to login in the APC's logs file, though I do see connections when I manually login, e.g.:
02/21/2014 13:13:11 System: Console user 'apc' logged out from 192.168.1.216.
02/21/2014 13:12:40 System: Console user 'apc' logged in from 192.168.1.216.
A manual 'telnet [name] 22' command also works fine from the command line:
# telnet hac-pdu1 22
Trying 192.168.1.222...
Connected to hac-1-pdu1 (192.168.1.222).
Escape character is '^]'.

However fence_apc_snmp **does** seem to work:
# fence_apc_snmp --snmp-version=1 --community=public --ip=hac-pdu1 --plug=1 --username=blah --password=blah --verbose --action=status
/usr/bin/snmpwalk -m '' -Oeqn -v '1' -c 'public' 'hac-pdu1:161' '.1.3.6.1.2.1.1.2.0'
No log handling enabled - turning on stderr logging

.1.3.6.1.4.1.318.1.1.4.4.2.1.3.1 1

Does anyone have any ideas as to why fence_apc is not working?
Thanks!
Tony
