Website can not be accessed without www

In the linode DNS manager, make sure that the zone itself is example.com, and you have A records for (blank) and www hostnames pointed at your node's IP.

Then ensure that your webserver's configs are set to serve content for both example.com and www.example.com. In apache, this means you should have a "ServerName www.example.com" and a "ServerAlias example.com" line

Thanks a lot. Exactly what I needed.
