Ip Address of UDP messages in case of cluster

[siaemic]

We have a cluster with ServiceGuard.
Is it possible to obtain that when an UDP message is sent its IpAddress as source server is the virtual cluster ip address of the cluster and not the ip address of the actual running server ?

Hi,

If i am correct it is so that if you log into the package and create an UDP message will come from the node. You can test it installing a sniffer on the network, or telnet ( tcp but ok) to an other host and do a who -T.

HTH,

We develop an application that send SNMP TRAP (UDP) and we should obtain to have the cluster ip address as source of UDP packets.
Our application is automatically started on active server.

From what you say, I believe you need your application to respond with the relocatable ip address, rather than the stationary or fixed ip address.
You would need to create your application and have it bind to the relocatable address, and I suggest you may like to read the Managing Serviceguard manual at:
http://docs.hp.com/hpux/onlinedocs/B3936-90073/B3936-90073.html

and specifically Appendix C, subsection entitled:
Designing Applications to Run on Multiple Systems
