If you're on a Mac I know there is an app called little sniffer or something like that that identifies local application's network usage. On Linux there are a number of tools like jnettop, ntop (mentioned above), iptables , and others to help diagnose where traffic is coming from or going to. I tend to use 'iftop' (http://www.ex-parrot.com/pdw/iftop/) for monitoring what traffic is going where and how much bandwidth it is using. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com
