Ethereal/Wireshark - How to

[stian123]

Hi

I wonder if any of you have experience using wireshark as a troubleshooting tool? I understand that wireshark is a tool that gives you a view over packets sent and received between too locations. But what should I look for and do anybody have a checklist over what to look for that can be used when troubleshooting.

Yes, we use Wireshark (formerly Ethereal) for troubleshooting network issues, generally related to IP video calls. If you have Wireshark running, capturing the data on the LAN port of one end of the video call, you can generally see what is happening and where the issues are. Of course, you have to be somewhat familiar with the process of opening and closing connections and the call flow of IP video so you can interpret what you're looking at. Turning it on and capturing a session is a good way to learn the flow.
