I've got a 3Com ADSL router doing NAT for a handful of PCs on a small
network - two W2K Servers, two XP Pro W/S and one W2K Pro W/S.

Is there some software that I can install on *one* of the W2K boxes that can
monitor the network to tell me how all these PCs are using my Jetstream
bandwidth? I'm 10 days into a new billing cycle, have apparently eaten
900MB, and Telecom's tools are bloody hopeless. One of the servers is
running AD/DHCP/DNS. I don't have a Linux box so unfortunately that's not an
immediate option.

Thanks,

Alan

Does your router support SNMP?
If so, the numbers you want are already available.

Thanks for the reply.

Apparently. It's an Office Connect Remote 812.

I've never used SNMP before - what's the next step? I don't need anything
too technical - just a count of the MB transferred by NETBIOS name/internal
IP address would be good.

Hmm, probably it only tells you total throughput and not how much per
machine.

Well you could add performance counters to the network interfaces for
each workstation and examine the results remotely (i.e. use performace
under administrative tools - alas it will count local traffic too). Or
install some sort of third party tools (like netlimiter).

A linux firewall with accounting does spring to mind immediately for me
though. You can just sit there with the iftop program and see clearly
who is sucking the bnadwidth and indeed set up traffic shaping...
