Current agents support only limited set of security features provided by SNMP. They should be replaced with ones from STABLE3 as they are based on fencing library and they have better security support.

[root@z1 sbin]# fence_apc_snmp -a 1.1.1.1 -l x -p x -n 4 Timed out waiting to power ON Success: Rebooted [root@z1 sbin]# echo $? 0 Is this behaviour as intended? I tried it also against 127.0.0.1 an the result is identical. Does this really check that the node was powered off (i.e. fenced) which is very key part of fencing?
