Socket Programming - Sending/Receiving hex and strings

Question

I have the following code in C#:

Console.WriteLine("Connecting to server...");
TcpClient client = new TcpClient("127.0.0.1", 25565);
client.Client.Send(BitConverter.GetBytes(0x02));
client.Client.Send(BitConverter.GetBytes(0x0005));
client.Client.Send(Encoding.UTF8.GetBytes("wedtm"));
Console.Write("{0:x2}", client.GetStream().ReadByte());

For the life of me, I can't figure out how to transpose this to ruby. Any help here?

This is what I have so far, but it's not working as expected:

require 'socket'
s = TCPSocket.open("127.0.0.1", 25565)
s.write(0x02)
s.write(0x0005)
s.write("wedtm".bytes)
response = s.recvfrom(2)
puts "Response Size #{response.size}: #{response.to_s}"

The response should be 0x02

EDIT:

I'm assuming I have to use String#unpack on this, however, I can't figure out how to get "wedtm" to output to the appropriate \x000\x000\x000\x000 format.
