I am interested in opening a capture file in wireshark and then exporting the data in 'C arrays' format [Wireshark provides that option in its GUI. One can do it by following 'File->Export->as C arrays file' from the main menu.My question is how can I do this in perl? Can someone help me with a script for this?
I Would like to parse each and every packet of the wireshark capture. So I thought, I will first convert each packet to an array and then parse it. Do you have any suggestions on this? My capture consists of all IEEE 802.11 frames.
Net::Pcap doesn't understand ERF format files such as those that come from an Endace capture. (I get 'unknown file format' from the open_offline sub). ERF is identical to pcap, except that there is an additional timestamp that has a higher resolution than what pcap can provide. Tcpdump can parse ERF files no problem, but it seems that knowledge is in the tcpdump source and not libpcap itself (and therefore not Net::Pcap). Before I download and read the tcpdump source code to find the precise format and write my own parser, does anyone have one they'd like to share or is there a module out there I didn't find? Update: Actually tcpdump can not parse the native files that come from Endace resulting in the same error returned by Net::Pcap, which makes sense ('unknown file format').
I'm hoping someone can help me with the following issue. I wrote a Perl script to parse all the UDP packets from an offline Pcap file and then write all the UDP data. Hello, I am writing a perl script to parse pcap file from wireshark with Net::Pcap module, here are the simple code: use strict; use warnings; use utf8; use NetPacket. Recently I was reading the blogpost on the BrekingPoint labs log about parsing pcap files with Perl and I immediately said to myself: it is impossible that.
We discovered that mergecap is changing the files into the libpcap format which can then be read by libpcap/tcpdump/Net::Pcap. Mergcap converts from (File type: Endace ERF capture, File encapsulation: Endace Record File) ->(File type: Wiresharek/tcpdump/. - libpcap, File encapsulation: Endace Record File.

So, the wireshark programs can read the native Endace file format, but libpcap can not. Libpcap can however capture live from DAG's and the code seems to be there (pcap-dag.c).
