You've got at least a couple options to use Wireshark for this: 1) write your protocol out in libpcap format. If one of the existing link types for libpcap does not fit your protocol then you could ask the libpcap people (tcpdump.org) to allocate a new DLT_ value for your lowest-level protocol. Then add support for that link type to Wireshark's wiretap library and then write a dissector that registers with Wireshark for that link type. 2) if you've already got a file format [and you don't want to change it], you could add support in Wireshark's wiretap library for that log file and then (again) write a dissector that registers to receive the read-in data. You mentioned a file with a bunch of hex strings which makes me think it's an ASCII file which makes me think that reading and processing that file wouldn't be fun, but I imagine it would still be possible. _______________________________________________ Wireshark-dev mailing list [email protected] http://www.wireshark.org/mailman/listinfo/wireshark-dev
