Many Thanks to the responses that I got from Lawrie Smith -
unfortunately we couldn't find the answer between us.

However I have sort of found "an" answer!!! There was a spare NIC in
the server which was un-configured and down (this was purely there as a
backup in case of main NIC failure). I configured up the spare NIC and
wahey off she went!!!

Odd thing is that the UDP broadcast is now working throught the primary
NIC and not the spare one that I configured up !?!?!?!

Anyway problem solved :-)

Regards

Andy

Managers,

I have a 2-node ES40 Tru64 v5.1B cluster. We have installed Oracle 9iAS
on the 2nd node - now here's the problem.

A small application that is required for the Reports Server to run
communicates with an agent which runs on a windows 2k pc. Tjis is done
via a UDP broadcast through port 14000.

I have been using tcpdump to monitor what is going on and have managed
to find out that if we run the application from node-1 the server
broadcasts through the correct port and receives a response JACK.4920 >
193.35.14.255.14000: udp 76

However if I run the same application from the 2nd node we get no
broadcast or response?????

I initially thought it might be something to do with the selp in the
cluster but eliminated that one (I think)

Can anyone help me on this one?

Regards

Andrew
