Hmmm. NPSRobustLogin() prints that it is being called, then calls
NPS_connect_device() and if that is successful, calls NPSLogin(). The
first thing NPSLogin() does is print that it is being called so, because
that is not showing up in the logs, it looks like NPS_connect_device()
is hanging while attempting to telnet to the IPS device. I'm pretty
sure that the -p option just takes the options positionally (ipaddr
first string, password second), I don't think it also parses out
name/value pairs, so your line above is attempting to telnet to device
ipaddr=172.16.9.37, which probably won't have very successful results.
Don't use the -f or -p options if you are going to use name/value pairs
on the stonith command line. So, either try:
stonith -d -t wti_nps -p "172.16.12.37 xpance" -T off XNET3
or
stonith -d -t wti_nps ipaddr=172.16.12.37 password=xpance -T off XNET3
and see if that gets you any farther...
