Unpack and Network Packets

mongre has asked for the wisdom of the Perl Monks concerning the following question:

I am sniffing traffic with the Net::Pcap module and I am having a heck of a time figuring out how to turn the binary packed data into some usable (ie ip addresses, ports etc) Has anyone done this? I could sure use some tips or a code snippet, what I have found so far can get me the Hex for Ethernet Addresses but that is all I have been able to get... unpack (" H12 H12 H4 H*",$pkt) Thanks for any help you can provide.. Cheers Terrence

    I was just playing with pcap recently myself, I found these helpful modules:

    Net::PcapUtils
    NetPacket::Ethernet
    NetPacket::IP
    NetPacket::TCP

    Hope they help, good luck.
