In TCPServer (Ruby), how can I get an IP / MAC from a client?

I want to get the client IP address in TCPServer in Ruby. And (if possible) the MAC address.

For example, a time server in Ruby, see the comment.

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

Many thanks!

Ruby 1.8.7:

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

Ruby 1.9 makes it simpler:

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

Use socket.addr:

irb(main):011:0> socket.addr
=> ["AF_INET", 50000, "localhost", "127.0.0.1"]

It returns an array showing the type of socket, port, and host information.

MAC-, , , . MAC-, "" . MAC-, arp . , , , MAC- .
