Great Monks, I am stuck on a problem with the IO::Socket module and a simple piece of code. Here is the background... I am using a script to open 100 socket connections on one port, after I open the sockets I want to be able to close a few of them and open a few more, etc... running this on Active state 5.8 and 5.05... for AIX and neither the close or shutdown calls on the socket seem to be completely tearing the socket down? when I have closed down 5 sockets and run a netstat on my port the status is set to CLOSE_WAIT. a 'friend' w/ root access that ran an iptrace for me told me that my client isn't sending the final FIN ACK...? I looked in perldoc IO::Socket and perldoc Socket and didn't see any clues into the low level TCP protocal. Any ideas of where to go from here would be much appreciated! 
  my $count = 0;
  my @sock;
  while ($count < 100)
  {
    $sock[$count] = IO::Socket::INET->new(PeerAddr => $args{h},
                                          PeerPort => $args{p},
                                          Proto => 'tcp',
                                          Type => SOCK_STREAM,
                                          Timeout => 10);
    print "\nCONNECTED TO HOST:$args{h} PORT:$args{p} $count times \n"
+;
    $count++;
  }
  sleep 10;
  my $count2;
  while ($count2 < 5)
  {
     shutdown ($sock[$count2], 2);
     print "Closed $sock[$count2]\n";
     $count2++; 
  }
  sleep 15;
}
