Rails - Mar 2006 - breakpointer socket errors?

I''m not sure what has changed that could have caused this, but lately, 
I''m unable to run the script/breakpointer script with my application. 
The application is just loaded up as webrick like:

=> Booting WEBrick...
=> Rails application started on http://0.0.0.0:3000
=> Ctrl-C to shutdown server; call with --help for options
[2006-03-20 12:42:48] INFO  WEBrick 1.3.1
[2006-03-20 12:42:48] INFO  ruby 1.8.4 (2005-12-24) [i386-linux]
[2006-03-20 12:42:48] INFO  WEBrick::HTTPServer#start: pid=5864 
port=3000

And running script/breakpointer:

/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 `open_server''
        from /usr/lib/ruby/1.8/drb/drb.rb:1336:in `initialize''
        from /usr/lib/ruby/1.8/drb/drb.rb:1624:in `start_service''
        from 
/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/breakpoint_client.rb:146
        from 
/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/breakpoint_client.rb:145
        from /usr/lib/site_ruby/1.8/rubygems/custom_require.rb:21:in 
`require''
        from 
/usr/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active_support/dependencies.rb:214:in
`require''
        from 
/usr/lib/ruby/gems/1.8/gems/rails-1.0.0/lib/commands/breakpointer.rb:1
        from /usr/lib/site_ruby/1.8/rubygems/custom_require.rb:21:in 
`require''
        from 
/usr/lib/ruby/gems/1.8/gems/activesupport-1.2.5/lib/active_support/dependencies.rb:214:in
`require''
        from script/breakpointer:3

Any clues where to start looking for what is wrong?  I get a connection 
refused trying to just telnet to the 42531 port on localhost.

0.0.0.0? you may like to check your /etc/hosts if on a *nix. Things tend 
to go better with the followings in it...

[user@localhost]$ cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1               localhost.localdomain localhost

IIRC 0.0.0.0 tells the server to listen on all interfaces.

It doesn''t mean that you point your browser at 0.0.0.0 - you still use 
localhost, 127.0.0.1, or the real IP address of the machine in your URL.
