Hi Falko,

crontab -l

* * * * * /usr/local/ispconfig/server/server.sh &> /dev/null

I checked the daemon ISPConfig runs on cron, but cron only runs every one minute, it takes too long to change the configs of the hosts.

You could not put a single daemon in perl done to reduce this time to 20 seconds, here's the script to be placed in /etc/init.d/boot.local

Add script in /etc/init.d/boot.local /usr/local/ispconfig/server/start_server.pl --start

/usr/local/ispconfig/server/start_server.pl --start (Start)
/usr/local/ispconfig/server/start_server.pl --stop (Stop)

script: /usr/local/ispconfig/server/start_server.pl

#!/usr/bin/perl

use Getopt::Long;
use POSIX qw(setsid);


my $start_daemon = 0;
my $stop_daemon  = 0;

GetOptions ('start' => \$start_daemon, 'stop' => \$stop_daemon ) or ( &help );


my $work_dir     = '/usr/local/ispconfig/server/';
my $child_STDOUT = '/var/log/ispconfig/ispdaemon.log';
my $pid_file     = '/var/run/ispdaemon.pid';
my $exec_command = '/usr/bin/php -q /usr/local/ispconfig/server/server.php';



if($start_daemon){

my $PID = &daemonize();
open PID, ">$pid_file" or die "Can't write to $pid_file: $!";
print PID "$PID\n"; close PID;

while (1) {
    print "Start Daemon ispconfig\n";
    `$exec_command`;
    sleep(20);
}

}

if($stop_daemon){

if(-e $child_STDOUT){
  unlink $child_STDOUT;
}

if (-e $pid_file){ 
 chomp(my $pid2 = `cat $pid_file`);
`kill -9 $pid2`;
 unlink $pid_file;
}

}



sub daemonize {
        chdir $work_dir or die "Can't chdir to $work_dir : $!";
        umask 0;
