can't access the admin interface, apache lost the conf?

[Esuk]

A couple of days ago the hosting company where my server is standing had some netissues and my server was offline for a couple of hours. When the server came back again I couldn't access the ISPConfig Admin page anymore.
(located at https://87.237.208.94:81)

I have browsed these forums for a while to see if I can find a solution to my problem but nothing seems to do the trick for me.

- I checked wheter or not ISPconfig was running but it wasn't so I started it but still no luck in accessing the admin page.

- I checked my "netstat -tap" but can't find any problems there

- I then turned to apache and the httpd.conf and when I looked thrue it I can't find any directions to listen on port 81 for ISPConfig. The only things I have is my vhosts and they are working nice.

I suspect that it's the apache conf that is missing but I don't know how to restore it.

My httpd.conf can be found here http://www.esuk.se/temp/httpd.conf
and the vhosts here http://www.esuk.se/temp/Vhosts_ispconfig.conf

Well I can't see any apache listening on Port 81.

There is an http on 80 and 443 but that's the one for your website, not the one ISPConfig is using.
Try /etc/init.d/ispconfig_server start ;)

Because if I make a netstat -tap then there is sth like

tcp 0 0 *:81 *:* LISTEN 1450/ispconfig_http

[till]

First, the directions to listen on port 81 are not in your apache configuration, ISPConfig has its own apache installed in /root/ispconfig/httpd/ so your apache configuration is OK.

Please run:

/etc/init.d/ispconfig_server start

[Esuk]

Thank you for your quick response :)

doesn't seem to get the :81 for ISPConfig and the Admin interface isn't avaiable :/

[Ben]

does /root/ispconfig/httpd/logs/error.log tell anything between a stop and restart?
Maybe is httpd crashed?

[Esuk]

I had a look and it shows a lot of errors.

That seems if anything with your ssl certs is broken...

if i look at

[Mon Jul 24 09:15:01 2006] [warn] pid file /root/ispconfig/httpd/logs/httpd.pid
overwritten -- Unclean shutdown of previous Apache run?


Would that time match the "network" crash of your provider? If yes, sure that it was only the network not the powerline? Maybe a power loss on your server caused a demage on your filesystem destroying any certs?
Or just take a look at you uptime to see if your server was rebooted withoud you knowledge...

[Esuk]

I re-generated the server cert as described by falko in this thread http://www.howtoforge.com/forums/showpost.php?p=358&postcount=4 and after restarting ISPConfig the problem was solved.
(I can now access the admin interface and I got ISPConfig listening on port 81)

netstat -tap
tcp 0 0 *:81 *:* LISTEN 22042/ispconfig_htt

Thank you all for your help, I don't regret changing from "the Pleskvirus" to ISPConfig, my best decission ever!
