Different wireshark behaviour on Linux as on Windows

Hello I am developing a plugin, which will dissect protocols, where other dissectors are already registered. Two instances are the Ethernet Powerlink dissector as well as the Sercos III dissector. My protocol is part of their communication messages, but can not be identified as easily, as e.g. an UDP payload, as it is encoded in the transmitted messages. Therefore, I kind of have to take an heuristic approach an dissecting the various frames. This works well so far, but now I have come across a funny situation. My main development plattform is Linux. On it, my plugin get's loaded, everything get's dissected correctly, and works as intended. My plugin is called openSAFETY. On Windows, the SercosIII plugin takes precedence over my plugin. Both register the same Ethertypes, therefore this should not be unusual, but as told, the situation is directly opposite towards the Linux side. Interesting side-fact, the EPL plugin, which is part of the main wireshark library, never gets called before my own plugin. There on both plattforms, my plugin get's called first. So my question is, can I influence the decision made by wireshark in any way, which plugin get's called? In every case, the dissector immediatly before my dissector get's called is the default Ethernet dissector. kind regards, Roland ___________________________________________________________________________ Sent via: Wireshark-dev mailing list <wireshark-dev () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-dev Unsubscribe: https://wireshark.org/mailman/options/wireshark-dev mailto:wireshark-dev-request () wireshark org?subject=unsubscribe
