Server Reboot

Server Reboot + PLESK Firewall ?

Hi,

i have a problem with what i have to admit, i can´t fix. I have PLESK 7.5 running on my rented Debian Root Server. The PSA was running and I had just the ports blocked and open that I needed. 2 days ago, i decided, because i had some strange problem with my webserver, to make a reboot.

But after the reboot the Server didn´t came back. So after hours of wondering why, i wrote a support ticket to my serverhoster and he wrote me that the Server had in fact rebooted but was blocked for any port other than 2.

NMAP:

Starting nmap 3.81 ( http://www.insecure.org/nmap/ ) at 2006-09-30
15:16 CEST

Interesting ports on xxx.server4you.de (xx.xx.xx.xx):

(The 1661 ports scanned but not shown below are in state: closed)

PORT STATE SERVICE

80/tcp open http

443/tcp open https



Nmap finished: 1 IP address (1 host up) scanned in 2.106 seconds

How the hell could this happen after a reboot ? I am not so the linux & server expert, i must admit, this is not solvable for me, I just dont know what the problem is. I checked the PSA Settings on the console, the Ports were exactly the same that was set from me, so those ports couldn´t be closed but they are.

Someone suggested that maybe something isn´t started correctly anymore when the Server boots but i find the psa-firewall Files in the /etc/rc?.d folder, so it should have been started.

What can be the problem ? I am thankful for any help.

I am not very familiar with Debian, but it sounds like the operating system has firewall rules that are loading after PSA and overriding the PSA rules.

I would poke around in your sysinit scripts. I know on Red Hat distributions you can do "/sbin/chkconfig --list iptables" to see if the OS is loading firewall rules.
