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/squirrelmail/index.php

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

    Please advise...

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

    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

    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?

    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.
    
    --- 216.128.67.247 ping statistics ---

    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.

    Maybe it's a firewall problem. What's the output of
    Code:
    iptables -L
    ?
     
  9. FOBioPatel

    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)

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

    /etc/init.d/networking restart

    and my problem solved itself. I swear I did that 100 times before and even rebooted the server; but this time it did the trick.

    Thanks again!
