The Wireshark will not identify your dissector.
Basically lets assume your protocol
dissector runs under TCP then , if you have heuristically registered
Your dissector with the ffunction
heur_dissector_add("tcp",
dissect_your_protocol_tcp,
proto_your protocolrefernce);

heuristic Dissector vs. normal dissector
Thanks for the
information!
But, without a Port number, how can wireshark find (identify) the correct
dissector for the incoming packets. What are specific criteria? Maybe you can
give me an example. I'm a bit slow on the uptake at the moment.

Basically Heuristic Dissector means that your dissector will
accept all the Traffic Packets and will not segregate based on port number.
So to identify your own custom dissector protocol messages
you have to separate out the packets based on certain criteria specific to your
Protocol.
And a normal dissector is registered with the Wireshark
based on port information which tells the Wireshark on which port your
message is
Going to be exchanges.
I hope it clarifies.
Hemant.
Hi!
What are the differences between a heuristic dissector and a normal dissector.
So far i have not considered heuristic dissectors, because I did not know what
they are and how to use them.
Maybe you can help!
Thanks in advance Tom (Germany)
