this example is grabbed from the help.
in order for socketting to work the server side must reply with a policy file

and here is a simple ruby script that talks with my as socket, not going to explain it to much, google on policy files there is someone that has already written a policy file server
#ruby
require 'socket'
include Socket::Constants
socket = Socket.new( AF_INET, SOCK_STREAM, 0 )
sockaddr = Socket.pack_sockaddr_in( 843, 'localhost' )
socket.bind( sockaddr )
socket.listen( 5 )
client_fd, client_sockaddr = socket.sysaccept
client_socket = Socket.for_fd( client_fd )
pf = "<?xml version=\"1.0\"?>
<!DOCTYPE cross-domain-policy SYSTEM \"/xml/dtds/cross-domain-policy.dtd\">
<cross-domain-policy>
<site-control permitted-cross-domain-policies=\"master-only\"/>
<allow-access-from domain=\"localhost\" to-ports=\"2929,843\" />
</cross-domain-policy>\0"
puts "The client said #{ client_socket.readline.chomp }"
puts (client_socket.write pf )
puts "The client said #{ client_socket.readline.chomp }"
puts ( client_socket.write "hello\0" )
socket.close
