Using that is basically the same as +using method 1: you still have to put a server at a static IP that gives +you off the dynamic IP. + +><i> > 2: The client submits its login, password, and system capabilities. +</I>><i> +</I>><i> In plaintext ? +</I> +If we assume the link has a crypt method in it, why not. + +Three possible methods for password submission + +1) Plaintext, assuming the connection has a form of crypt in place +2) MD5/crypt password. Spoofable, since: + a) You can capture the MD5/crypt string + b) You have the client source, so can hack it to send the static + crypted password instead of crypting the - unknown - plaintext +3) MD5 for a dynamic challenge. A good example: the server sends you the + current date when you connect, and you use that date as the first + bytes of the MD5 digest. + +><i> > 4: The client selects the world it wants to log on, and submits the IP address +</I>><i> > of its world service to the LS. +</I>><i> +</I>><i> Would it be good if the client could select several worlds ? +</I>><i> (then the negociation following could use this to get a good WS) +</I> +Not good. Typically, the client will connect to the world the player has +a character he wants to play today :) + +However, the client may use the IP addresses of the WS to ping them and +figure out which connection is better (when selecting its first world). + +><i> So the WS is (or can be?) a load-balancer to all the FES in a given world ? +</I>><i> -- the balancing being done at network level, not process level -- +</I> +The WS *is* the load balancing mechanism. Since he's aware of all FES +up and running, and knows their load right now, he's best suited to +determine which FES can afford to manage a new character. + +><i> I wonder if it couldn't be more interesting if the client disconnects from LS +</I>><i> _after_ having initiated the connection to the FES.
