Re^4: Getting ethernet type using NetPacket

What part did you have trouble with ? Any error messages ?

If you un-comment the lines below, it will print packets as they arrive.

    #print("RcvPkt Totlen(PacketLen) $hdr->{len}($hdr->{caplen})" .
    #  "\t Time.Usec=$hour:$min:$sec.$hdr->{tv_usec}\n");
[download]

If you capture packets, you can control-feed them into the program (read pcap docs), and run the "perl -d <program>" debugger, and examine data as you go.

If you examine the parameters, you will notice that there is hard-coding to look for an "intel" type NIC. `"NETWORK_INTERFACE => 'intel',# Network interface to open` [download] Try modifying that to match your hardware, or change it to a proper parameter...
