Hi!

My DRB server should print a message if a new client has connected,  
maybe also with some details of this new client (IP or something like  
this). Is there a function that could help my with this problem?

ALEX

That should go in your front object, the one you pass to  
DRb.start\_server

$ cat c.rb  
require ‘drb’

client = Object.new  
def client.name() ‘Jimmy’ end

DRb.start\_service  
server = DRbObject.new nil, ARGV.shift  
server.connect client

$ cat s.rb  
require ‘drb’

front = Object.new  
def front.connect(client)  
puts “client #{client.name} connected!”  
end

DRb.start\_service nil, front  
puts DRb.uri  
DRb.thread.join

$ ruby s.rb &  
[1] 22125  
druby://kaa.coop.robotcoop.com:53485  
$ ruby c.rb druby://kaa.coop.robotcoop.com:53485  
client Jimmy connected!
