However, most of the hacking problems I've seen these days +on MMOGs do not involve a spoofed server or anything else. They're all +revolving around: + +1) A scam aimed at getting your login and password + (we have this incredible powerleveling service. Send us $30 and + your password and we'll have you level 50 in a month) + +2) A trojan (last one on EQ pretending to be an 'undetectable macro + program') that intercept the login/password pair when you *type them*. + +Still, it doesn't hurt to make a MD5 challenge. If someone can spoof +you into believing you're talking to the server, the usual crypto layer +that protects your connection against sniffing will not protect your +password (something some web designers conveniently forget, saying that +once you're using https:// urls, you can send you password in clear to +the web). + +><i> >serves as authentification, and the WS then updates the LS with its state, +</I>><i> >name and IP address.

But when you +start talking multiple OC12 links for your bandwidth consumption, you +quickly have limits on where you can locate your worlds. It is a lot easier +to negociate several locations with OC4 for each than say "I need a place +with two OC12". + +Lag is another one. All the world is not the states... tell it to the Aussies +who ranted and screamed till they finally got one Ultima Online server +down under. We're doing our best to make lag irrelevant, but given the +choice of playing on a server with 500 ms ping and a server with 100 ms +ping times... The experience with the latter will always be a *lot* +smoother. + +And finally security. Not network security, I'm talking real security. +Despite every premium paid, what happens if your server room catches +fire, and despite generous smothering of Halon, all your servers are +burnt to a nice crispy taste? Sure, the insurance will pay you lots of +money. But your players will no longer be there. + +Spreading your servers around makes sense on several points. + +-- +Vincent Archer Email: <A HREF="mailto:archer@nevrax.com">archer@nevrax.com</A> + +Nevrax France.
