Quoting Chuck B <chuckbowling () att net>:
I'm new to Wireshark and not all that familiar with network protocols in general. Is it possible to filter everything from a capture session but only the things specific to that capture session? To clarify; I want to study all of the interactions that an app has with multiple servers and multiple ports. But, there are a lot of packets mixed in with the capture that don't have anything to do with the apps interactions. What I want to do is shut down all unnecessary traffic on my system then capture all of the traffic between my ethernet card, router, and ISP. After the capture I want to filter everything that has been captured including all ARP, DNS, DHCP etc.. However, I don't want to make the filter too generic and have it filter things that I want to see. Once I have a list of all interactions I want to start another capture using the filter, open my app, and watch the interactions between it and whatever servers it connects to. Is that possible? And, if so, what is the easiest way to achieve that goal? ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
Chuck-From time to time I troubleshoot applications that have problems communicating with the Internet.
Although it makes sense to apply filters to your capture, you just never know what vital piece of information you would end up missing by doing so.
I personally do *not* apply filters to Wireshark or tcpdump captures and later piece the communication streams with display filters. They're many ways to accomplish what you're looking to do. When I am met with an overly large capture I just extract streams and join them all together.
A handful of people I know use the Wireshark configuration profiles which I think ultimately its what you are looking for.
Have a look at the link: Customizing Wireshark and hope you find it useful. http://www.wireshark.org/docs/wsug_html_chunked/ChCustConfigProfilesSection.html ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org?subject=unsubscribe
