You can set the TOS flags with Socket.setsockopt passing IPPROTO_IP as the level, IP_TOS as the name of the option, and your desired value:

require 'socket'
s = TCPSocket.new('example.com', 80)
s.setsockopt(Socket::IPPROTO_IP, Socket::IP_TOS, YOUR_TOS_VAL)

This works on Linux. Thanks so far, but would there also be something similar for Windows? – Deadolus Jun 15 '09 at 11:26

Try Socket#setsockoption(). Its documented in Appendix A of the pickaxe book, or you can browse the source for interface details.
