Arijit:

I commend you for including the code, but what's the problem you're having with counting the packets? Don't just tell us you have a problem with it, tell us what the problem is. I don't mind reading the code looking for an issue, but without knowing exactly what the problem is, I don't know what sorts of errors to look for.

Having said that, I read the code anyway. When I looked for counters, the only thing I found is:

my $count = 0;
Net::Pcap::loop($object, -1, \&syn_packets, '$count++') ||
    die 'Unable to perform packet capture';
print "$count";

I don't have Net::Pcap installed on my machine, so I'm not trying out your program, but seeing '$count++' looks like an obvious problem. First, since it's in single quotes, the $count variable won't be interpolated. Second, since it's a function call argument, and the function call isn't in a loop, it will be evaluated only once. Third, the documentation mentions that the argument is simply a chunk data to pass to the callback, not a code reference to execute. I suggest adding $count++ to your callback function and eliminating the '$count++' argument.
