Hi Guys,

i have the following......
file.pl

#!/usr/bin/perl

use warnings;
use strict;
#!/usr/bin/perl

use warnings;
use strict;
use IO::Socket;
$| = 1;
my $port = 7777;

my $server = IO::Socket ->new(
        Domain => PF_INET,
        LocalPort => $port,
        Proto => 'tcp',
        Listen => SOMAXCONN,
        Reuse => 1,
);

die "Bind failed: $!\n" unless $server;
#tell OS to clean up dead children
$SIG{CHILD} = 'IGNORE';

print "Multiplex server running on port $port...\n";
while(my $connection = $server->accept){
  my $name = $connection->peerhost;
  my $port = $connection->peerport;
  if (my $pid = fork){
     close $connection;
     next; # on to the next connection
   }else{
     # child process - handle connection
     print $connection "You're connected to the server!\n";
      while (<$connection>){
        use HTTP::Date;
        my ($date, $time) = split(" ", HTTP::Date::time2iso());
        my ($hour, $min) = split(":", $time);

         my $log;
         open ($log, '+>>',"logs/$port $date.txt") || die "Couldn't op
+en log.txt: $!";
         print $log $_;
         close $log;
         my $dir = "logs";
         my $file = "logs/$port $date.txt";
         chmod (0777, $file);
         chmod (0777, $dir);
     }
    $connection->shutdown(SHUT_RDWR);
   }

Basically all it does is listen for conections on a certain port number, and then writes the data recieved to a log file,
the above code works 100% for what i need,
My problem is if i start the script using Putty SSH like so ./file.pl
then its all fine, it creates the connections and if the connection is terninated it cleans up the dead children from the server, and releases the port again,
however, if i start the script like so
nohup ./file.pl
then it doesnt cleen up the dead children and keeps the port also in use after the host has disconnected
I need this file to be running all the time, could someone please tell me the correct way of doing this, or is there a problem in my script somewhere?

Please guys i really need to try and get this fixed
