hello monks,
I have a cap file which contains bunch of udp files using perl(but no modules, no pcap or any other modules) and want to just deal in lowlevel. But(and this might not be a perl question but since there are so many all around programmars here) what i cannot figure out is, when i open the cap file, how to tell where one udp packet starts and where it ends..(i am trying to just count bytes but not sure where to stop counting)..
