Viewing TCP.http traffic?
Posted: May 6, 2005 10:09 PM

I'm unable to view any http traffic on the network. I'm going thru a hub and can see plenty of conversations (broadcast, spooler jobs, etc), but no http protocol. Out of 200 computers I know someone is on the Internet. The only Internet traffic I can see is when a browser is opened on the computer running the probe, then I can view those conversations. Is it wishful thinking on my part that I can monitor Internet usage with this, or do I need to configure something to do it network wide?

Thanks for any help

Where in the network is the hub placed? The hub must be placed so that it can see all traffic. For instance in front of the firewall.

Some low-cost hubs are switches labeled as hubs. Try another one if you're not sure if it actually is a hub.

You got me, the hub was a switch, I thought I had it covered with a 5 year old Netgear DS516, but nope it still behaved like a switch. Replaced it with a 6 year old Linksys and now I can see everything.

Thanks again
