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...

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

Code:

debian:~# netstat -tap

Are there any errors in your logs?

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

[Tue Aug 19 08:03:06 2008] [warn] (101)Network is unreachable: connect to listener on [::]:443

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?

ifconfig output:

/etc/init.d/networking restart

Code:

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:~# ping debian.responsiveweb.com

PING debian.responsiveweb.com (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

64 bytes from google.navigation.opendns.com (208.67.217.230): icmp_seq=2 ttl=56 time=1.61 ms



--- google.navigation.opendns.com ping statistics ---

2 packets transmitted, 2 received, 0% packet loss, time 1003ms

rtt min/avg/max/mdev = 1.377/1.496/1.616/0.125 ms

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

Code:

iptables -L

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.
