There are certain things you need to do with a daemon, to make it a real daemon. Search groups.google.com for "perl daemon" for alot of discussion and sample scripts. There is also a modules to make it easy....Proc::Daemon

Here is the basic idea. 

#!/usr/bin/perl
use warnings;
use strict;
use POSIX 'setsid';
use IO::Socket;

$|++;
my $server = new IO::Socket::INET (
      LocalHost => 'localhost',
      LocalPort => '7070',
      Proto => 'tcp',
      Listen => 1,
      Reuse => 1,
             );
 die "Could not create socket: $!\n" unless $server;
$server->autoflush(1);

daemonize();

open(LOG,">/tmp/7070.log") or die "$\n";

while(1){
   while ( my $client = $server->accept() ){
      sysread($client, my $buf, 100);
      syswrite(LOG, "$buf\n");
      LOG->flush;       
      }
}

#################################################################

sub daemonize {
  chdir '/' or die "Can't chdir to /: $!";
  open STDIN, '/dev/null' or die "Can't read /dev/null: $!";
  open STDOUT, '>/dev/null'
          or die "Can't write to /dev/null: $!";
  defined(my $pid = fork)    or die "Can't fork: $!";
  exit if $pid;
  setsid or die "Can't start a new session: $!";
  open STDERR, '>&STDOUT'    or die "Can't dup stdout: $!";
}
