my server has very old perl 5.005 (and upgrade is not an option). and I wish to go through number of pcap file. I tried to manually install Net::Pcap w/ no success.
Next thing I am wondering about is, is there way for me to peek into the individual *.cap file and see what it contains?

Here are my main problem
1)I have looked at cap file with wireshark but do not understand where each packet starts and end. Trying to see if I can just byte count(if i can tell where each packet starts and stops) till specifics of each payload(UDP for example).
2)Can you just read first 100k of cap file and save it to another name? meaning will it retain valid cap format and just less of it(say if original file was 1Mb).
3)can someone give me a good pointer or link where binary file is well explained?
thank you so much
