Getaddrinfo: Name or service not known

[Kikanny]

Hi. I'm using puppet 2.6.1 on ubuntu lucid. I'm running puppetd and
puppetmasterd on the same machine. When I try to run the puppet agent,
I get the following error:

err: Could not retrieve catalog from remote server: getaddrinfo: Name
or service not known
err: Could not retrieve catalog; skipping run

I am completely clueless on what this means. Any help would be
appreciated! Thanks!

Got this fixed with Patrick's help. I had to add puppet as an alias in
the /etc/hosts file. For more info:
