One Answer:
Those functions needs to be exported to be available by plugins on Windows. You could try a built in dissector instead. answered 20 Jun '14, 09:35  Anders ♦ |
Thanks, I will try the built in dissector method. But in general, is it possible to write a custom plugin based on CSN.1 encoding using the APIs provided by packet-csn1.
how to decode a message which is not mentioned in decode as and my message was compiled and it is showing in wireshark enable protocols but it is not mentioned the decode as filter,can any body help me..
Currently not as the API isn't exported. I think that is solved by adding WS_DLL_PUBLIC to the needed functions. This makes a plugin problematic as the Wireshark base for the plugin will have to have the changes incorporated and if you need a released version of Wireshark you will have to wait untill a released version with this changes are available.
That depends on how your dissector is called, via a TCP/UDP/SCTP port or? The decode as API has been greatly improved in the uppcomming 1.12 release. You may be better off working with that.
Have you considered contributing your code to Wireshark which would make all of this much simpler...
