Untangling the dns hell
Tue Aug 11 19:16:29 +0200 2009
The site has been offline a few days now due to my dear friend Joel's flaky connection.
He's on a 10mbit host provided through a web-login which for some reason kept logging him out every now and then..
The simple solution was to add an auto-login script to the crontab; luckily this guy had already written a script for Joel's provider.
But a new problem appeared, sometimes the server received a new IPaddress from the provider and that sure caused quite alot of trouble.
We're having 4 different domains pointing to this address including their sub-domains and keeping all those in sync would become a manual labour since neither one.com or loopia.se provides commandline tools to update their entries (In a sense that is unnessecary since usually it's simply the wrong approach).
So this is how it's solved!
First register a free hostname at www.no-ip.org , in our case I registered warcamp.no-ip.org
Then install and configure their auto-update client. If you're on debian/ubuntu you can simply type: sudo apt-get install noip2
Once you have one dns synced with your server you can then simply point all other domains to that address using an CNAME entry; in my case pointing to warcamp.no-ip.org
Notice: Due to specification limitations you cannot use a CNAME entry for your root domain (e.g. .tonyivanov.se). A simple workaround is to create an CNAME record for www.yourdomain.com and then modify the root record to web-hop to www.yourdomain.com
Voilá! You have an automatic dns synchronization!
