I'm not sure what to search for on google for this, but something strange happened when I restarted apache2. I'm using an ubuntu server, 11.04, and got this message
apache2: Could not reliably determine the server's fully qualified domain name, using 18.104.22.168 for ServerName
A strange IP, not even close to the one I have. Could it be someone changed this? Is there a way to change it back to 127.0.0.1?
