在TCPServer(Ruby)中,如何从客户端获取IP / MAC？

我想在 Ruby中的TCPServer中获取客户端的IP地址.并且(如果可能的话)MAC地址.

例如,Ruby中的时间服务器,请参阅注释.

tcpserver = TCPServer.new("",80)
if tcpserver
 puts "Listening"
 loop do
  socket = tcpserver.accept
  if socket
   Thread.new do
    puts "Connected from" + # HERE! How can i get the IP Address from the client?
    socket.write(Time.now.to_s)
    socket.close
   end
  end
 end
end

非常感谢你！

>> fam,port,*addr = socket.getpeername.unpack('nnC4')
=> [4098,80,209,191,122,70]
>> addr
=> [209,70]
>> addr.join('.')
=> "209.191.122.70"

>> port,ip = Socket.unpack_sockaddr_in(socket.getpeerName)
=> [80,"209.191.122.70"]
>> ip
=> "209.191.122.70"
