I'm searching an easier way to configure my xymon 4.3.5 server other than specifying @IP at each test necessary in hosts.cfg.
I think there are only two ways to do this: append "@IP" to every test; and define FPING to be "xymonping --source=IP". Obviously, the latter only works with ping/conn tests, and I don't think it gets used if "--ping" is on the xymonnet command-line (in tasks.cfg). From reading the source code, I can't see any other mechanism for overriding the O/S-provided address.
There's probably a way to do this using policy routing. If a policy route is selected, and the "src" hint is defined in the route table entry, then it will be used for the source IP address. A route table entry can be selected based on a "mark" applied by netfilter (iptables). You can mark a packet based on things like the PID, UID and GID of the process, and the process command-line. It sounds like a lot of fun, but it's not something I'd want on my networks.
