(De nada ;-)) I am happy you have solve your problem but take into account that if the computers you are monitoring are not in an independent network all the computers in that network will be catching the gmond communications. This is because 224.0.0.1 is a well defined multicast address. Try doing ping 224.0.0.1, then all the computers in that net should be responding. This is not something to worry about as network performance will not be affected nor security compromised. If you find out how to configure Linux to use another multicast IP let me now :-).
Cheers, Roman PS: I am using Fedora Core 1 with Kernel 2.4 and no solution with multicast yet.
