Hi Folks I am trying to implement the genisys dissector without much success. Is the code that is linked to the "New patch to add genisys dissector" link a single file that must be saved as "packet-genisys.c" and compiled? or what must be done. Is there somewhere where I can get the group of files associated with this dissector eg Makefile.am, makefile.common, moduleinfo.h .... I am sorry if this is not the correct place for this type of request but this is all I could find. Many thanks Simon(The wireshark-dev mailing list is the correct place for this discussion). You first need to be able to build Wireshark from source. The Developer's Guide has lots of information about the process of setting up a build environment, obtaining the sources and doing the build. See: http://www.wireshark.org: Develop ! Developer's Guide Once you've accomplished that you can then apply the patch attached to Bug #3422 (using the 'patch' program) and then rebuild Wireshark. The patch (presumably) has all the required source & Makefile changes to build the genisys dissector as part of Wireshark. I should note, however, that the patch is a year old so it may not apply cleanly against the current source tree or even the sources for the current 'stable' version of Wireshark (1.2.6).Hi Bill Thanks for the help. I have installed all the required programs and can compile
and
run wireshark no problems. I have used the packet-genisys.c code published here in an earlier post and attempted to compile it with suitably modified support files like makefile.am etc. I can compile the packet-genisys.c without any problems but when I put the genisys.dll file in the plugins directory and try to run wireshark
it
crashes. There must be somthing wrong with ether the packet-genists.c code or the support files that I have edited. Does the patch file create the support files and Where do I find the patch program? I presume I have to copy the code attached to
bug
#3422 and save it as some kind of file that the patch program can use? Lastly do I have to recompile wireshark? all the examples and tutorials seem to indicate that all I have to do is copy the compiled genisys.dll file into the plugins directory and run wireshark. Regards Simon
(Note: Please send replies to wireshark-dev () wireshark org and not to my personal EMail). 1. Are you building on Windows or *nix ? What compiler are you using ? You speak of DLL's (which are Windows) yet you also speak of modifying makefile.am which is *nix. The two don't mix. Eg: You can't use makefile.am & etc when building on Windows. 2. The patch file attached to bug #3422 when applied to the Wireshark source does *not* add the dissector as a plugin but changes the source to build the dissector as an integral part of Wireshark; Therefore I don't understand what you are actually doing when you speak of generating a genisys.dll. Did you change things around to try to build the dissector as a DLL ? I suggest that the your first step is to build Wireshark using the genisys dissector (and changes to certain other source files) exactly as supplied in the patch. Trying to change things to build the dissector as a plugin is not the way to start if you're new to Wireshark development. 3. It appears that you are unfamiliar with the 'patch' program and how it works. Again I suggest you review the Developer's Guide as mentioned above. See sections 3.9, 3.10 and 4.14 for information on patch. Hi Bill Thanks again for your help. I am running on a windows XP machine and following this tutorial http://www.codeproject.com/KB/IP/custom_dissector.aspx There are obviously two approaches to this: 1) incorporate the protocol as an integral part wireshark as I think you are describing or 2) run it as a .dll plugin as I was trying to do (as per the tutorial). I presume that this genisys protocol has not been implemented into the general release of wireshark (it does not appear in the list of protocols) I only hope that this is because it is a rather obscure protocol and not because it doesn't work. Getting back to the "Patch" thing, I have read all the stuff in the developers manual and hope I understand it, is this what I have to do? 1) Click on the "New patch for genisys dissector" link at https://bugs.wireshark.org/bugzilla/show_bug.cgi?id=3422 2) Copy the code and paste it into a text file 3) save it as "add_genisys_dissector.diff" (or something similar) 4) copy the file into the c:\wireshark directory 5) open a command window and go to the c:\wireshark directory 6) type "patch -p0 <add_genisys_dissector.diff" 7) re-compile wireshark I will not try it until I hear back from you as I really don't want to stuff the existing wireshark files :) Cheers Simon ___________________________________________________________________________ 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
