Yes Dirk, just got the mail but already find where the problem is... You 
are 100% right, only root can bind privileged ports, but as for me - not 
so good to run spider as root :-) to prevent sonme h at ckers to get my 
rootshell :)
So I did next: running cluster as user sysop on port 22223 and doing 
redirect to 23 using firewall.

====part of firewall file=====
#start cluster redirect
$iptables -t nat -A PREROUTING -p tcp --dport 23 -j REDIRECT --to-ports 
22223
#end cluster redirect


Solved.

BY THE WAY - MAYBE YOU NEED TO ADD IT TO FAQ:

now running spider under Kubuntu 6.10, in this system is no inittab file.

If you're using Edgy, inittab has been split off into several files,
most of which are inside /etc/event.d, if I recall correctly.
Inittab and the new configuration files are somewhat similar, but you 
might have to get creative.

So I made a file in /etc/event.d named "cluster" contains next:

---------------start----------------------
start on runlevel-2
start on runlevel-3
start on runlevel-4
stop on shutdown

respawn /bin/su -c "/usr/bin/perl /home/sysop/spider/perl/cluster.pl" 
sysop >/dev/tty8
------------------end--------------------

after the file is done, do telinit q, this will run cluster as sysop. If 
you need, redirect ports to any below 1024 and viola!

Thank you very much!
