How to do TOS/DSCP in ruby?

问题

How does one set the TOS flags/DSCP flags in Ruby on a UDP/TCP stream (preferably using the Ruby/Sockets library)?

回答1:

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)

回答2:

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