News from 28 April 2009

ADSL update and server maintenance

As I wrote in News from 8 April 2009 Cybercity planed an update on the central we are connected to. The update would culminate on April 27 where the internet would be gone for most of the day.

The letter we received did mention that we would get a new IP, but the IP they listed as our new IP was the old one. So I just thought that we would continue with the old one.

But that part of the letter seems to have been a mistake. When configuring the router after the time when the update should be finished I noticed that we had gotten a new IP. A trip to MyIP (external link) confirmed it.

As I knew from past experiences that the IP update takes about a day before everyone has the new one, I choose the use this unwanted event to do maintenance on the server.

I was unhappy with the spamfilter I was using, but the one I used to use is not recommended by the authors if used with mbox mailfolders. The default IMAP server for slackware does not understand Maildir mailfolders so I wanted to replace it with dovecot.

And I really wanted to prevent image hotlinking or leeching of images on my server. I remembered that I had read somewhere that Lighttpd could do this easily internally. And I did not feel confident that sendmail was the best choice for mail server.

These things made me backup the server and start fresh to erase all traces of sendmail from it, etc.

Well, a long story short. In the search for the hotlinking prevention instructions for lighttpd I found an easier and more straightforward approach for Apache and so I just installed almost the same system all over again. I could have saved me some time just replacing uw-imap with dovecot. But that is easy to say now...

The server should be back to normal operation some time today.
