power failure caused ISPConfig to start up with a weird problem
 
My services show the following:

Code:

Web-Server:          Offline
FTP-Server:        Offline
SMTP-Server:        Offline
POP3-Server:        Offline
BIND-Server:        Offline
mySQL-Server:        Online

The web server is working, despite showing that 'offline' status. I assume everything else is working as well, but my webmail has stopped working. Squirrelmail complains:

http://debian.responsiveweb.com:81/s...mail/index.php

Error connecting to IMAP server: localhost.
110 : Connection timed out

Please advise...

FOBioPatel 18th August 2008 23:18

and before someone asks me for a netsat -tap output:

Code:

Are there any errors in your logs?

FOBioPatel 19th August 2008 16:25

what is the path of the logfile you need to see? I am not sure what to look for...

I can't find any relevant errors in the apache error.log, or in the mail.err.0 logfile under /var/log/apache2 and /var/log

apache's error.log has many lines which read as follows:
Code:

[Tue Aug 19 09:24:41 2008] [error] an unknown filter was not added: PHP
This line appears about 2 to 3 times every second, which is troubling... and occassionally I see the following:

Code:

[Tue Aug 19 08:03:03 2008] [error] an unknown filter was not added: PHP
[Tue Aug 19 08:03:03 2008] [error] an unknown filter was not added: PHP

I am doing some more Google-ing and found the following:

What's the output of
Code:

ifconfig
?

Can you try to restart the network on the command line? Do you get any errors then?

FOBioPatel 20th August 2008 15:49

ifconfig output:

/etc/init.d/networking restart

Code:

debian:~# /etc/init.d/networking restart

done.

The GUI in Debian shows that I do not have network access, which is odd - I am online...

I tried to PING localhost and got impatient:

Code:

debian:~# ping localhost
PING localhost.localdomain (127.0.0.1) 56(84) bytes of data.

--- localhost.localdomain ping statistics ---
151 packets transmitted, 0 received, 100% packet loss, time 150008ms

I tried to PING the server using its hostname and IP:

Code:

debian:~# ping 216.128.67.247
PING 216.128.67.247 (216.128.67.247) 56(84) bytes of data.

--- debian.responsiveweb.com ping statistics ---
7 packets transmitted, 0 received, 100% packet loss, time 6000ms

I tried to ping a website I am running in ISPConfig (which is up, and working just fine, despite the ISPConfig webserver showing that it is 'offline')

Code:

debian:~# ping www.responsiveweb.com
PING www.responsiveweb.com (216.128.67.247) 56(84) bytes of data.

--- www.responsiveweb.com ping statistics ---
5 packets transmitted, 0 received, 100% packet loss, time 4000ms

And then of course; I had to PING google.com

Code:

debian:~# ping www.google.com
PING google.navigation.opendns.com (208.67.217.230) 56(84) bytes of data.
64 bytes from google.navigation.opendns.com (208.67.217.230): icmp_seq=1 ttl=56 time=1.37 ms

Maybe it's a firewall problem. What's the output of
Code:

iptables -L
?

FOBioPatel 21st August 2008 20:54

Code:

debian:~# iptables -L
Chain INPUT (policy ACCEPT)
target    prot opt source              destination

Chain FORWARD (policy ACCEPT)
target    prot opt source              destination

Chain OUTPUT (policy ACCEPT)
target    prot opt source              destination

Looks good. Maybe it's a hardware problem (RAM maybe)? You can check RAM with memtest.
