tcpdump and/or wireshark: http://www.tcpdump.org/ http://www.wireshark.org/
The latter used to be called Ethereal, and the GUI was in fact written by an earlier kclug member. Ethereal at least, is available on windows. Run it on the client or server or both with a sufficiently tight filter. It watches the 'wire' and your filter narrows down what it reports so your screen isn't flooded. The filter "host 192.2.0.1 and port 80" would be sufficient on your laptop to limit reporting to traffic on your server (192.2.0.1) on port 80 (web). Show up at the next meeting, and I can demonstrate wireshark in action. I use my Time Warner connection alot, and haven't seen much interference, malicious or accidental. (Aside from when I saturate my link with traffic.)
If you can ssh to your server from the meeting, you can do a remote packet capture with tcpdump -w, then scp it to your laptop and view it there with wireshark. It's likely some sort of misconfiguration, or malformed POST request though, but wireshark can rule out network interference.

While I can be massively entertained by the sociological/political/religious meanderings of some folks who post here, my primary interest is in learning as much as I can about, you guessed it, LINUX. So, howzaboutit? If some folks wish to beat each other about the head and shoulders in a virtual world, why not go pick an open field and go at it for real instead of wasting our collective in-boxes with non-linux trivia?
I have an Ubuntu Linux-related question.
I've been running an Ubuntu server for several months. I'm very pleased with how easy it is to run. Uptime is very good. On the other hand, I swear that Time Warner is interfering with my connection from home to the server which is located elsewhere. Time Warner provides Internet service to both locations. I'm getting dropped pages and seeing an inability to submit forms on the remote server. I'm using Firefox 3 at home on a laptop running Windows XP. I seldom see the same problem when the laptop is on the same network as the server.
Can folks recommend any good network analysis tools that we can install on the server?
