What's the underlying link-layer type for the packets in your rf5 file?
good bad ol' E.1/MTP2 (I am almost tempter to add "of course" here)
Let the user read a text file containing raw packet data in hex-dump form
without requiring them to go to the command line and run >text2pcap. Uhm, maybe I am slow wit here but we have SS7 MTP2, MTP3, SCCP there so as NOT text-based protocols as one can imagine or do I miss something? Then again, if SS7 MTP2 is supported can we just "strip" somehow K-12's overhead here and run text2pcap on whatever reamins there? /wbr Ariel Burbaickij On Mon, Mar 4, 2013 at 8:40 PM, Guy Harris <guy () alum mit edu> wrote:

Neither. The list of link-layer header types is not frozen, but there is not, and probably never will be, an official tcpdump.org project or Wireshark to add particular link-layer header types; new types are added when somebody sends a request for a type to tcpdump-workers () lists tcpdump org and the request is accepted. The current list, and instructions on how to add values, are at http://www.tcpdump.org/linktypes.htmlSo why isn't that good enough?Because we would like to replay (using tcpreplay) files in pcap format,among other things. Adding a new link-layer header type won't be sufficient; you'll also have to write a DLT plugin for the new type: http://tcpreplay.synfin.net/wiki/tcpeditDeveloper What's the underlying link-layer type for the packets in your rf5 file? What might be called for here is an *export* option to strip off metadata that's neither needed nor wanted by particular programs, converting encapsulations with no corresponding pcap/pcap-ng link-layer header type to one of those link-layer header types."Open packet hex dump text file",Let us try to work backwards here -- what is it actually supposed to do?Let the user read a text file containing raw packet data in hex-dump form without requiring them to go to the command line and run text2pcap. ___________________________________________________________________________ Sent via: Wireshark-users mailing list <wireshark-users () wireshark org> Archives: http://www.wireshark.org/lists/wireshark-users Unsubscribe: https://wireshark.org/mailman/options/wireshark-users mailto:wireshark-users-request () wireshark org ?subject=unsubscribe
