prime Posted September 26, 2007 Share Posted September 26, 2007 Is there a way to tell if 2 separate people are actually the same computer rather than just say using a router reason I'm asking is, there is a game I have been playing called travian, and here is their rule, and this actually makes me quite curious * §2.2 Same pc usage If there are two or more players using the same computer and playing on the same game world, all affected accounts must be listed in the profile by using the "PC use with another player" function of Travian. Abuse of this function is punishable. Playering on different computers on the same network does not qualify as "same pc usage". Players using the same computer and wanting to access each other's account must use the sitter function. Read §3.2 for details about limitations for resource transfers. I know you can check remote address and browser type, but it just seems to me like an idea like this would be catching people using routers as well, or is there another way to do this that I'm not seeing.

prime Posted September 26, 2007 Author Share Posted September 26, 2007 then wouldn't that just be easily beaten by using different browsers? since each browser stores the cookies in separate locations. Quote Link to comment Share on other sites More sharing options...
Psycho Posted September 26, 2007 Share Posted September 26, 2007 True, but that was just one thought. They could be using some client-side script to populate a hidden field that is getting posted to the site. Quote Link to comment Share on other sites More sharing options...
rarebit Posted September 26, 2007 Share Posted September 26, 2007 If their on the same internal network, then they should have differing MAC address's (but can be spoofed), I think there's a PEAR package for getting MAC address's, but i've not tried with php!

prime Posted September 26, 2007 Author Share Posted September 26, 2007 you mean the MAC-address validator (Net-MAC), only works over a local network though doesn't it? since the mac address isn't sent over the headers Quote Link to comment Share on other sites More sharing options...
