pingd.c needs glib header

Hi,

Little patch for pingd.c
Compiler might complain about g_timeout_add_seconds().
There is no " #include <glib.h> "

Re: samba resource agent

We get all our RAs from Heartbeat and it doesn't look like they have one yet.
They're pretty easy to write though

of course.
i believe the point is that as the distance increases, so does the
number of switches/telcos involved and therefor the probability of a
comms failure is between the two sites is quite high.
as is the latency...

I got the logs.
Log says, "ret = snmp_send(session, trap_pdu)" completed successfully.
but SNMP manager couldn't get any traps.

Re: handling snmp trap with crm_mon

I just tried again, and its working here.
How are you checking for traps?

I get the following:
