More advanced Example
on server:
require 'findme'
Findme.cleanup
Findme.register "findme", 1337
on client -> client.rb:
require 'findme'
SERVICE = "findme"
services = Findme.discover
services.select{|s| s.service == "_#{SERVICE}._tcp"}.each{|s| puts "#{s.ip}:#{s.port}"}
on client discover latest and earliest -> client_earliest_latest.rb:
require 'findme'
require 'pp'
SERVICE = "findme"
h = Findme.discover_only_earliest
h.select{|k,s| s.service == "_#{SERVICE}._tcp"}.each{|k,s| puts "#{k}|#{s.ip}:#{s.port}:#{s.txt}"}
h = Findme.discover_only_latest
h.select{|k,s| s.service == "_#{SERVICE}._tcp"}.each{|k,s| puts "#{k}|#{s.ip}:#{s.port}:#{s.txt}"}
results on client.rb:
