Hello fellow monks,

I created a simple 'server' script that will accept input from a cgi script. The server will handle multiple connections on the same port, also. In a nut shell, this 'server' script will take in variables, and fork off a process to sleep for a given amount of time, and then send the user an email (and perform other functions).

Here is my problem: I receive a confirmation e-mail once the connection has been made, but i do not receive the other e-mail (which is supposed to be sent from the forked process once the sleep() is up). I receive one confirmation e-mail per client, but I will never receive the second e-mail. I don't know why the forked process is not working as I think it should?

Also, the problem ONLY happens when I daemonize the process. If i simply run the script inside a terminal 'perl server.pl', it will work perfectly fine and I will get all the desired results. However, when I daemonize it by 'perl server.pl &', the functions within the fork, including the second e-mail, will not be executed.

Shouldn't I be able to daemonize it and get the same results?

Here is the code:

#!/usr/bin/perl

# includes and dependencies....

use strict;
use warnings;

my $max_clients = 10;
my $port = 15100;

while(1)
{
my $sock = new IO::Socket::INET (
        LocalHost => 'localhost',
        LocalPort => $port,
        Proto => 'tcp',
        Listen => $max_clients,
        Reuse => 1,
                                );
    die "Could not create socket: $!\n" unless $sock;

    my $new_sock = $sock->accept();

    while(<$new_sock>)
    {
         # parse information

         close($sock);

         #send e-mail function here

         unless(fork)
         {
         # sleep for given time
         sleep(30);

         # perform function

         #2nd send e-mail function here
         exit(0); 

         }
 }
}

Thanks in advance!
