tshark

Platform :- Fedora 13 32-bit machine

RemoteMachine$ ./rpcapd -n

ClientMachine$ tshark -w "filename" -i "any interface name"

As soon as capture starts without any capture filter, thousands of packets get captured. Rpcapd binds to 2002 port by default and while establishing the connection it sends a randomly chosen port number to the client for further communication. Both client and server machines exchange tcp packets through randomly chosen ports. So, I cannot even specify the capture filter to block this rpcap related tcp traffic.

Wireshark & tshark for Windows have an option "Do not capture own Rpcap Traffic" in Remote Settings in Edit Interface Dialog box. But there is no such option in tshark for linux.

It will be also better if anyone can tell me how wireshark blocks rpcap traffic....

Saving Wireshark capture settings for future use

Is there any way to save Wireshark capture options? So it can be reuse after restart Wireshark. Also, if the saved file is in plain text, it's possible to use scripts generating bunch of capture settings, such with different filter setting. Does anyone know? Thanks. >>> More
