I use the Solarwinds Engineer's suite for bandwidth monitoring, as for packet sniffing I use the Ethereal packet sniffer from http://www.ethereal.com/. It's helped me out quite a few times.
Solarwinds you have to pay for, but Ethereal is free.

Sorry to be a little OT on this one, but I'm sure I'm not the first to run into it. I have a server on the network that is pushing a lot of bandwidth both in and out. Very unusual for a web server - normal MRTG shows lots out, minimal in. I don't know if it is a trojan or what. I've used MRTG to monitor the network and tracked it down to the machine. The problem is there are 250 sites and 250 IP addresses on the machine and I need to monitor the bandwidth usage on each IP address separately. I tried What'sUp Gold but couldn't find anything in there to do it. As far as log files go, no indication there of activity. I even shut off FTP service in the middle of the night for 15 minutes to see if the inbound traffic would drop and it did not, which makes me think there is another type of problem. What I would love is a program that can take all of the IP's on the machine and in a spreadsheet-type format, list all of the IP addresses, incoming traffic and outbound traffic. Does anyone know of a tool like this? If What'sUp can do this, can anyone steer me in the right direction?
