Wireshark · Ethereal-dev: [Ethereal-dev] Protocol dissector conflict

[Peter Johansson <Peter.xc.Johansson@xxxxxxxxxxxx>]

A dissector I wrote is hooked up to handle tpc.port == 14000. This works 
well most of the time.
I just saw MSNMS (Messanger) as the description of the decoded protocol 
when it infact should have been my dissector's name (OCP).
The reason for this is that the port in the other end of the tcp 
connection matched MSNMS' port (1863).

Is there an intelligent way of ensuring the "correct" dissector handling 
the PDU or do I have to disable Messanger (in this specific case) as a 
decoder alternatively to use the "decode as" option?
