More DRb Fun

I'm not sure why I'm having so much fun with DRb, really:

kevin@itzamna:~/drb$ ./server.rb
/usr/lib/ruby/1.8/drb/drb.rb:837:in `getaddrinfo': getaddrinfo: Name
or service not known (SocketError)
        from /usr/lib/ruby/1.8/drb/drb.rb:837:in `open_server_inaddr_any'
        from /usr/lib/ruby/1.8/drb/drb.rb:860:in `open_server'
        from /usr/lib/ruby/1.8/drb/drb.rb:756:in `open_server'
        from /usr/lib/ruby/1.8/drb/drb.rb:754:in `each'
        from /usr/lib/ruby/1.8/drb/drb.rb:754:in `open_server'
        from /usr/lib/ruby/1.8/drb/drb.rb:1335:in `initialize'
        from /usr/lib/ruby/1.8/drb/drb.rb:1624:in `new'
        from /usr/lib/ruby/1.8/drb/drb.rb:1624:in `start_service'
        from ./server.rb:9
kevin@itzamna:~/drb$ cat server.rb
#!/usr/bin/env ruby
# simple_service.rb
# A simple DRb service

# load DRb
require 'drb'

# start up the DRb service
DRb.start_service nil, []

# We need the uri of the service to connect a client
puts DRb.uri

# wait for the DRb service to finish before exiting
DRb.thread.join

This is on a fresh install of Debian Sarge, and I'm pretty sure I've
grabbed all the Debian Ruby portions off of apt-get...

Any ideas why I'm having this trouble?

Here I go solving my own problems again.

The thing that threw me was the error message. Turns out the problem
was that the wrong hostname was in the top line of /etc/hosts, so the
host name of the machine wasn't mapping to 127.0.0.1.
