Don't blame us Oregonians. :-) > Anyway, could anyone shed some light on what application or > service on the > server is causing this? I have a theory. I wonder if it is NetMonitor itself. It might be looking for banner ads or gathering data for one of its tests? Do you see this traffic even when not using NetMonitor? Try Ethereal.

It's truly a pain. The official list from the Internet Assigned Numbers Authority just says this, as you probably know: osu-nms 192/tcp OSU Network Monitoring System osu-nms 192/udp OSU Network Monitoring System # Doug Karl You could ask Doug?? :-) Are you sure it's not port 92, instead of port 192? That would make more sense. Here's what IANA says about 92: npp 92/tcp Network Printing Protocol npp 92/udp Network Printing Protocol Or maybe 192 is Hex?? Probably not though. That would be 402, which doesn't seem any more likely: genie 402/tcp Genie Protocol genie 402/udp Genie Protocol # Mark Hankin Sorry I can't be more help.
