Wireshark · Wireshark-dev: Re: [Wireshark-dev] Byte matching

[Matteo Pelliccia <matteo.pelliccia@xxxxxxxxx>]

Hi Jeff,

thank you for your answear. I was looking at the code, for what I understood the matching is held by the function dfvm_apply. Are there any connection beetween the structure dfilter_t and the original pcap file? I can print the value matched pretty easily.

Hi to all,
maybe it's a silly question. Is it possibile to know what byte match in
display filter _expression_? For example if I have a pcap file with some
packet and I run tshark with -Y option I would like to know which bytes
match that _expression_, is it possibile?

Unfortunately no, not today.  There's been some discussion of highlighting the field (if not the bytes) in the GUI (there's probably a bug requesting that) but this is the first time I've heard of it for tshark.
