I'm trying to get a simple 'listner' to work. Here is what I have; A host that is constantly sending text to another host on a particular port.

All I want to do is record (for now send to stdout) that data, AND here's the problem, be able to kill the listner at any time.

But when I kill the listner, the sending host stays in CLOSE_WAIT

anywhay here's my dumb little program ....

-------------------------------------------------
#!/usr/bin/perl

use IO::Socket;
use IO::Select;

sub sig_do {
  my $signame = shift;
  $got_usr1++;
}

$shucks = 0;

$SIG{USR1} = \&sig_do;

$local_port = 2282;

$local = IO::Socket::INET->new(Proto=>"tcp",
                               LocalPort=>$local_port,
                               Listen=>"1"
                              ) or die "Can't open socket\n";

# wait for connection and create a new handle
$remote = $local->accept;

while (<$remote>) {
  if($got_usr1) { last };
  $data = $_;
  $peer_addr = $remote->peerhost;
  print "PEER:$peer_addr DATA:$data";
  #play with data ....
}

printf "USR1 signal, now close the connection\n";

close $remote;
close $local;
