Hello,
If you look at "Analyze / Enabled Protocols ...", you have the list of
protocols known by wireshark.
I do NOT see any Thunder protocol.
It could have another name or simply wireshark do NOT know it.
NB: you can disable a protocol in this window.
If Thunder use the same udp port as OICQ (= 8000 inside wireshark code),
you can see Thunder packets as OICQ packets.

Dear all,
Here I have a very detailed question and I would like to thank you all
for your help in advance.
Some background information first:
Thunder is a very popular P2P file downloading software in China and
it is not open sourced. Recently I have been doing some protocol
analysis experiments about Thunder by Wireshark. Experiment
descriptions are as follows:
Experiment 1 : Close other applications and run Thunder------I will
get a lot of packets with the protocol name as OICQ. (OICQ is a very
popular IM soft ware in china but actually during this experiment I
did not open it).
Experiment 2: keeping all other setting unchanged, I close Thunder,
immediately after experiment 1---------Here I did not get any OICQ
packets anymore.
Actually I have talk to some guys who work in OICQ company and
according to them, Thunder and OICQ are competitors and there are not
any co-operations between them. So I am really confused that how I
can capture OICQ packets from Thunder while the OICQ is not running.
Therefore, if it is possible, may I ask how Wireshark works and
decide a packet is an OICQ packet? I mean, besides of the UDP port,
are there any other ways for Wireshark to categorise a packet to be an
OICQ packet?
Actually I am really confused here and your help will be really
appreciated for me.
Thank you in advance and best regards,
Adele JIA
