Hello,

I am trying to get DRb to work between two different hosts, but I am unable 
to.

I have followed the PickAxe and the introductory course in 
http://segment7.net/projects/ruby/drb/introduction.html. For example, this 
code:

== server.rb ==
require 'drb'

class TestServer
  def add(*args)
    args.inject{ |n,v| n + v }
  end
end

server = TestServer.new
DRb.start_service('druby://localhost:9000', server)
DRb.thread.join
==========

== client.rb ==
require 'drb'

DRb.start_service()
obj = DRbObject.new(nil, 'druby://localhost:9000')
puts "Sum is: #{obj.add(1,2,3)}"
==========

It works fine if I start both the client and the server in the same computer, 
but if I start the server in host A and the client in host B (replacing 
druby://localhost:9000 with druby://hostA:9000), it does not work. 

Host A and host B are able to ping each other, they do not have any firewall 
installed and host A's IP and host B's IP are both resolvable (via hosts 
file) in both machines. I have also tried using the IP instead of host A's 
name.

Any tip? Do I need to make the server observable or something like?

Thank you.
