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...

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 08:03:04 2008] [warn] (101)Network is unreachable: connect to listener on [::]:443 [Tue Aug 19 08:03:05 2008] [warn] (101)Network is unreachable: connect to listener on [::]:443 [Tue Aug 19 08:03:06 2008] [warn] (101)Network is unreachable: connect to listener on [::]:443

What's the output of Code: ifconfig ? Can you try to restart the network on the command line? Do you get any errors then?

/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!
