multiple xymon server IP
This is what I had hoped to hear.
Thanks much.

If the two addresses are in the same network, it should be trivial. Just create an ip-alias and go for it. Xymon will not care what interface the packets come in over. It will get annoyed if you have clients transmit every conditon to it twice (I have had that problem every now and then).
I curently have a dual homed server. One interface is connected to a subnet inside of campus and the other interface goes directly outside of campus to a state network. My default route is across the external interface with routes defined for all campus address spaces to go over the campus interface.
All of this works a lot better than expected. A few clients attempt to send reports to both interfaces and for the ones that firewalls do not block, I get double entries -- annoying. Someday I will get all the clients configured properly.
Hopefully this info will help.

Built a new xymon server to replace an older box. We have a DMZ. To avoid doing the paperwork to create new firewall rules I was hoping there was a way to "multi home" the new box so that, once the current one is retired, it can assume that IP be happy, from a xymon perspective.
Simply changing the new server to a single (old box) IP is not feasible for reasons I cannot get into.
Thanks for any pointers.

Oh, another thought.
I would like the new xymon box to send out tests/ requests on the alias IP.
(firewall issue again).
If I change the host IP to the alias in the various xymon config files (once the old box is retired), and restart xymon, am I correct in assuming it would use the alias for outgoing xymon related stuff?

Joseph, you can override the default source IP address for xymonnet by adding "--source-ip=ip.add.re.ss". You would make this change in tasks.cfg.
Any tests that aren't handled by xymonnet (eg custom scripts such as devmon) would have to do the equivalent.

Thanks. I guess that goes in the [xymonnet] section as part of the CMD line ?
