Thanks for reply. There are so many things in perl which i need to learn. And what about printing information about bytes sent/received and total without doubling the lines?
Session REC SENT Bytes Total

I did it by this non-professional newbie code, which I wrote before (now it's a little bit modified):
#!/usr/bin/perl
use NetPacket::Ethernet;
use NetPacket::IP;
use NetPacket::TCP;
use Net::TcpDumpLog;
use strict;
use warnings;
if ($#ARGV gt 0 ) {
print "Usage: pcap.pl <pcap.file>\n";
exit;
}
my %sum;
my $key;
my $keyx;
my $log = Net::TcpDumpLog->new();
$log->read($ARGV[0]);
my @keys = ();
foreach my $index ($log->indexes) {
my ($length_orig, $length_incl, $drops, $secs, $msecs) = $log->header($index);
my $data = $log->data($index);
my $eth_obj = NetPacket::Ethernet->decode($data);
next unless $eth_obj->{type} == NetPacket::Ethernet::ETH_TYPE_IP;
my $ip_obj = NetPacket::IP->decode($eth_obj->{data});
next unless $ip_obj->{proto} == NetPacket::IP::IP_PROTO_TCP;
my $tcp_obj = NetPacket::TCP->decode($ip_obj->{data});
my $keyName = $ip_obj->{src_ip}.":".$tcp_obj->{src_port}." <-> ".$ip_obj->{dest_ip}.":".$tcp_obj->{dest_port};
if ($sum{$keyName}) {
$sum{$keyName} = $ip_obj->{len} + $sum{$keyName};
}
else
{
$sum{$keyName} = $ip_obj->{len};
}
}
sub hashSort {
$sum{$b} <=> $sum{$a};
}
my $cnt = 0;
print "\tSession \t\t\t\tREC\tSENT\tBytes Total\n";
print "===================================================================\n";
my $ip = "";
my $othcnt = 0;
my @arrayz;
my $firstvalue;
my $secondvalue;
my $thirdvalue;
my $forth;
foreach $key (keys(%sum))
{
my @excludeList = split("<->", $key);
$firstvalue = trim($excludeList[0]); # ip address
$secondvalue = trim($excludeList[1]); # ip address
foreach $keyx (keys(%sum))
{
@excludeList = split("<->", $keyx);
$thirdvalue = trim($excludeList[0]); # ip address
$forth = trim($excludeList[1]); # ip address
if (($firstvalue eq $forth) && ($thirdvalue eq $secondvalue))
{
$ip = &checkArray($thirdvalue,$forth);
if ($ip ne 666)
{
$arrayz[$othcnt] = $keyx;
$othcnt = $othcnt + 1;
my $suma;
$suma = $sum{$key} + $sum{$keyx};
print "$key \t $sum{$key} \t $sum{$keyx} \t $suma \n";
}
}
}
}
sub trim($)
{
my $string = shift;
$string =~ s/^\s+//;
$string =~ s/\s+$//;
return $string;
}
sub checkArray
{
my($a,$b) = @_;
my $arrayvalue="";
foreach $arrayvalue(@arrayz)
{
my @excludeList = split("<->", $arrayvalue);
my $one = trim($excludeList[0]); # ip address of first
my $sec = trim($excludeList[1]); # ip address of first
if ((($a eq $sec) && ($b eq $one)) || (($a eq $one) && ($b eq $sec)))
{
return 666;
}
}
}
And generally that is all which i want to get, so
REC BYES, SENT BYTES, TOTAL BYTES (REC+SENT).
However, it doesn't work quite well, because if i have completely different connections (client only sent some data didn't receive nothing for example) they won't be printed in output:
Session Bytes Total
