    126128If server has something to send, it will send a downstream data packet,  
    127129prefixed with 2 bytes header as shown above.

     1332. Raw UDP protocol 
     134====================================================== 
     135 
     136All Raw UDP protcol messages start with a 3 byte header: 0x10d19e 
     137This is not the start of a valid DNS message so it is easy to identify. 
     138The fourth byte contains the command and the user id.

     145Login message (command = 1): 
     146The header is followed by a MD5 hash with the same password as in the DNS 
     147login. The client starts the raw mode by sending this message, and uses 
     148the login challenge +1, and the server responds using the login challenge -1. 
     149After the login message has been exchanged, both the server and the client 
     150switch to raw udp mode for the rest of the connection. 
     151 
     152Data message (command = 2): 
     153After the header comes the payload data, which may be compressed. 
     154 
     155Ping message (command = 3): 
     156Sent from client to server and back to keep session open. Has no payload.
