is there a chance that there is a "Listen 8133" in your apache2 configure file? always no as "httpd.conf" or *.conf in the apache2/conf/extra folder.

Good Morning List ;)

ive allready postet my question on the german phpbar mailinglist, but no
responses from anyone yet. i hope someone on that list could give me an
advice or hint.

i'm writing a php-daemon which will run on a debian lenny/squeeze.
this daemon should listen to a specific port of a
vpn-interface/ip-address (it creates a socket)

if the daemon script recieves a string from my management webinterface
(other server) it should run some code e.g. exec('/etc/init.d/apache2
restart'); or system('something'); or whatever.

i got it working, but there is a (for me) strange behavior. After the
daemon has restarted the apache2 service for example and the php daemon
is stoped, the apache2 process takes over the socket. that means, in
`netstat -tulpen` or `netstat -anp` i first can see something like that:

tcp        0      0*    LISTEN      29168/php
tcp6       0      0 :::80         :::*       LISTEN      29155/apache2

after the daemon has restarted apache2 and stops itself (or i have to
kill him), netstat shows up the following:

tcp        0      0*  LISTEN      31490/apache2
tcp6       0      0 :::80         :::*         LISTEN      31490/apache2

so i cant restart the daemon because apache uses that port/ip (or socket?)

after invoking "/etc/init.d/apache2 restart" on the shell, everything is
fine again and im able to start the daemon. btw, the same with the
openvpn service. (mysql doesnt act like apache or openvpn).

Am i missing something? Or is that the default behavior of
linux/apache/php/sockets ???

Additional Information about OS etc.

Server/Client   Debian Lenny    Apache 2.2.9    PHP 5.2.6-1+lenny9 with
Suhosin-Patch (cli) (built: Aug  4 2010 06:06:53)

Client/Server   Ubuntu Lucid    Apache 2.2.14   PHP 5.3.2-1ubuntu4.5 with
Suhosin-Patch (cli) (built: Sep 17 2010 13:49:46)

Ive tested it both way: Ubuntu as Server, Debian as Client and vice versa.

The Ubuntu System (my workstation) is in our Office and the Debian
System is in the datacentre@ our provider...

Any help would be great!

Thanks in advance,

kind regards
