I think I'm close at finding how many times an element appears in the log file from each array, but I am getting the same results for each element. Here is my output when the script is ran: 
192.168.17.10 was seen 148 times
http was seen 148 times
192.168.12.187 was seen 148 times
ftp was seen 148 times

What am I doing wrong? Here is the code: 

#!/usr/bin/perl -w

use strict;
 
my $log = './logfile';
my (@data, @service, @dst, %count, %counts, %hash, %sizes, $dst, $serv
+ice, $ip, $times);
 
&check("192.168.47.3");
 
sub check {
  $ip = $_[0];
 
  open (LOG, $log) or die "Can't open $log: $!";
  while (<LOG>){
    push (@data, $_) if $_ =~ /$ip/;
     foreach (@data){
       ($dst, $service) = (split /;/)[11,12];
       next if m/^\s*$/; #skip any empty lines
       push(@service, $service);
       push(@dst, $dst);
     }
  }
 
  @service = &duplicates(@service);
  @dst = &duplicates(@dst);
 
  foreach (@data){
   foreach my $i (@dst){ 
    $count{$i}++;
   }
   foreach my $j (@service){
    $count{$j}++;
   }
  }
}  
 
while (my ($key, $count) = each(%count)){
  print "$key was seen $count times\n"; 
}  
 
sub duplicates {
  my @array = @_;
  my %saw;
  @array = grep(!$saw{$_}++, @array);
}
