Anti Feed PVP

[Bleadd]

Hi everybody,

 

I use this anti feed pvp : http://www.maxcheaters.com/forum/index.php?topic=171893.0

 

But We can also feed when a player isn't in party, in clan and it's a friend with other ip.. So how can i put an awaiting time (approximately 10 sec) ?

 

Example : player 1 kill player 2 at 11 h 03 and he get reward.

He kill again player 2 at 11 h 03 and don't get reward

but when he kill player 2 at 11h04 he get reward again.

You need to store somewhere IP's from which players logged on account. Then compare all of them if same isnt there (and eg. time of when logged from it). That wont fully work too and will be pretty easy bypassable. You could store (except for host ip's) also traceroute hops to gateway + local pc ip for comparing to detect dynamic ip's changes. Then you could run through all players on the server and build dependencies (detect which accounts are of same person, or are shared between same group of ppl). Add evaluation of how tight each accounts are connected, then check for antifeed comparing strength of connection between accounts (when 1st check for "shared" connecting from same networks appear) and decide if that strength is enugh to pass antifeed or not (if u block all accounts between each other when u detect same person logged on them, then eg shared "clan buffer chars" that many different ppl log on, will spread connections between all players that used them, what we dont want to do - so u need some proper evaluation for that). In short pretty amount of work and code, then tests... ;)

 

Fully working and tested implementation of such system is available from me if you're interested ;) Has over 95% of sucessfullness in preventing eg. olympiad feeds, but same time very low chance of blocking players that in reality are not feeding, but only eg. shared same crafter char, or someone from their clans shared them etc.
