[Technology] gethostbyname failed

I was trying to set up a Festival speech synthesis server to work with Speech Dispatcher and a Rhythmbox plugin I'm working on. Speech Dispatcher couldn't connect to it. I tried connecting to the Festival server with the Festival client, and that didn't work either, instead giving me an error "gethostbyname failed". I investigated and saw it should be trying to connect to localhost at 1314. I verified that my firewall and selinux weren't involved. Then I finally peaked at my /etc/hosts file, and sure enough a change I made a couple weeks ago broke it. I reverted that, and now it works again. Yay!
