I have jut joind small netwoking company that has just started up and to monitor the network radios we use a proggrame called the dude and it basicly pings all the radios on the network , but we use different radios and they use diferent IP's (192.168.1.x/192.168.150.x/ 192.168.160.x) so we need to use four difrent computrs to montor thr hole network so I was wondering weather its posible to use tree or more netwoking cards on one computer.
We have tyied puting the three difrent IP's on one coputer and the computer just seems to freez up ,So maby there is a better operating sistem I could get for this sort of thing or anything you can sujest

and how do you know if the mother board supports it?
