What do I need to do to make the following code write the input from  
each thread to all other active threads? I can’t figure out how to  
access the list of threads in GServer.

#Begin Test Server

require ‘GServer’

class TestServer \< GServer  
def initialize(port=4000, \*args)  
super(port, \*args)  
end #end initialize  
def serve(io)  
client\_info = Hash.new #Hash to contain connected client  
information.  
input = io.gets.strip #Input from client, stripped to  
remove newline.  
client\_info[‘name’] = input  
loop do  
str = io.gets  
io.write("#{client\_info[‘name’]}: #{str}")  
end #end loop  
end #end serve  
end #end TestServer

server = TestServer.new  
server.audit = true  
server.start  
server.join

You could keep a hash of connected clients (managed with  
TestServer#connected and TestServer#disconnected) and stow some  
information away in there, polling for it in your loop.
