network monitoring?

[David Lang]

Ok, now I have hearbeat up and working.

has anyone written scripts to monitor network connectivity?

I am useing this for firewalls and I want it to failover if one of the
ehternet connections fail.

currently if I set it to heartbeat on both connections then it will not
failover unless both connections fail.

I could write a script that pings out from each box to other machines on
the network and then kills hearbeat if there is no response, but if
someone else has done work in this area I don't want to duplicate it.
