Getting client IP from Ruby script through xinetd


How can I get the client IP Address from inside a Ruby script that is launched by xinetd through a stream socket? In PHP I would just use stream_socket_get_name(STDIN, true);

Thanks in advance!


Solution

  • After searching a lot for the solution, and even trying to ask on the #ruby channel on Freenode and being completely ignored, I've finally found the solution:

    def to_ip(addr)
      (4...8).map{|x|addr[x]}.join('.')
    end
    
    socket = Socket.for_fd(STDIN.fileno)
    ip = to_ip(socket.getpeername)
    

    Hope this helps someone!
