Hello,
I have host A (IP 192.168.1.3) and host B (IP 192.168.1.5), both of them
Linux
(KUbuntu 5.10) with no firewall. I am running ruby 1.8.4, installed from
KUbuntu packages.
If I run ringserver.rb, server.rb and client.rb in the same host, it
works
fine. (Source code is at the end of the message)
But if I go for the interesting case, i. e. running ringserver.rb (taken
straight from segment7.net) and server.rb in host A and client.rb in
host B,
it fails with a RingNotFound exception.
What am I doing wrong? Should I specify a port for Rinda? (I think the
broadcast list should be enough)
=== ringserver.rb ===
#!/usr/bin/env ruby -w
Start this one first.
ringserver.rb
Rinda RingServer
require ‘rinda/ring’
require ‘rinda/tuplespace’
start DRb
DRb.start_service
Create a TupleSpace to hold named services, and start running
Rinda::RingServer.new Rinda::TupleSpace.new
Wait until the user explicitly kills the server.
DRb.thread.join
=== server.rb ===
#!/usr/bin/env ruby -w
require ‘drb’
require ‘rinda/ring’
class TestServer
include DRbUndumped
def add(*args)
args.inject{ |n,v| n + v }
end
end
server = TestServer.new
DRb.start_service(‘druby://:9000’, server)
provider = Rinda::RingProvider.new :TestServer, server, “Test Server”
provider.provide
DRb.thread.join
==============
=== client.rb ===
#!/usr/bin/env ruby -w
require ‘drb’
require ‘rinda/ring’
DRb.start_service()
ringfinger = Rinda::RingFinger.new([‘192.168.1.3’,‘192.168.1.5’])
@ringserver = ringfinger.lookup_ring_any()
obj_tuple = @ringserver.take([:name, nil, nil, nil])
obj = obj_tuple[2]
puts “Sum is: #{obj.add(1,2,3,4)}”
Thank you.
