Hello,
Two of my dissectors that I wrote use the same tcp port, the ged125 (being reviewed) and a proprietary protocol). Their default port is both 5000. When I have the default ports the same the ged125 fails to dissect but the other one still functions. How do I overcome this issue?
As Jaap suggested: make both of them heuristic by making them "new style" dissectors that return 0 if they find the packet is not for them. (Search for "new_create_dissector_handle()" in README.developer.)
