Counter of the duplicated packets from a pcap file

You have different pieces in play. You should find out where the error is. Is find_dupl() broken, or is it okay and the problem is in duplication_pkg_count()?

First thing is that find_dupl looks odd to me. You're going to the trouble of making a nice Counter object, but then when you're done you're looping over it constantly. Much better it to just call into it.

I think instead of

    return [[s[index] for index, seq in enumerate(tcpSeq)
        if seq == key]
        for (key, value) in counter.items()
        if value > 1]

you could just do:

    return [s for s in tcpSeq if counter[s] > 1]

Also, maybe instead of 'counter' you could use a name like 'seq_count'.
