Hello Ryan,

this works, but maybe drb is better suited for your needs:

bschroed@black:~/svn/projekte/yamlserver$ cat server.rb
require 'socket'
require 'yaml'

server = TCPServer.new('127.0.0.1', 8585)

while (session = server.accept)
  Thread.new(session) do | s |
    p YAML::load(s)
    s.close
  end
end
bschroed@black:~/svn/projekte/yamlserver$ cat client.rb
require 'socket'
require 'yaml'

hash = { 'one'=>'1', 'two'=>'2'}

client = TCPSocket.new('127.0.0.1', 8585)
client.puts hash.to_yaml
client.close

regards,

Brian
