FLockClient - Server


ATTENTION: At this time I'm not able to maintain this project. If any experienced developer wants to maintain this project while I can't, contact-me.

FLockClient is a small and simple tool to force players to use the server defined .jar, It might be useful to modded server and also can work to prevent hacked clients, forcing all the players to use a clean .jar. A client-side modification is required.
