Hello,

My local IP address is 10.8.8.41. I could not figure out why when I  
use 127.0.0.1 the code works but fails when I use my IP address. The  
error is "druby://10.8.8.41:6438 - #\<Errno::EBADF: Bad file descriptor

- connect(2)"

require ‘rubygems’  
require ‘reliable-msg’

manager = ReliableMsg::QueueManager.new  
manager.start

queue = ReliableMsg::Queue.new ‘my-queue’, :drb\_uri =\> ‘druby://  
127.0.0.1:6438’  
#queue = ReliableMsg::Queue.new ‘my-queue’, :drb\_uri =\> ‘druby://  
10.8.8.41:6438’  
queue.put “This is a test object”

msg = queue.get  
p msg

manager.stop

Thanks
