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.

Pages: Instructions || Permissions || Key Numbers || Jenkins


  • Highly Configurable
  • Random security keys
  • Multiples clients
  • Force player to use a defined client
  • Permissions to each client
  • Download files from the server
  • Permanent ban by MAC address
  • more


FLockClient.DebugReceive in-game debug messages
FLockClient.F3Access access to the "F3" menu
FLockClient.TextureAbility to bypass the texture pack lock
FLockClient.hash.<client>Access to the <client> defined
FLockClient.Gui.DebugShow debug information on download
FLockClient.ByEmptyJoin the server without the client


  • /lc ban - Ban the player MAC address
  • /lc unban - unBan the player MAC address
  • /lc info - Show information about a client
  • /lc list - List players using any authorized client
  • /lc reload - Reload the configuration
  • /lc unex - Re-enable the anti-cheat protection


This plugin is made to work with a client mode that is available here, if you don't use the mod, the server will not recognise you!

    In its update I would like to give an idea to put some commands use only for those who have the client installed server. Thus have more people using this plugin for example people do not like having to download to enter the server but would have benefits like lowering /arena anticheat and /kit anticheat.

    Well, I finally bought myself a new notebook, it's been a while since the last time I used the internet :D, now I just need to get my shit together and get back to work.

    I see that some people started some similar projects, depending on how they are going I'll prioritise other projects and update this one later (they are easier to update, wont take much time as this one will) or perhaps just help them out and shutdown this one, dont know, lets see...

    yeah yeah I copy pasted some stuff, my english is rusty D:

    @AT_HE: Go

    Well, this is embracing... btw, i have talked with Furmiga before 2013's ending and his notebook is still not working for recover 1.6+ source-files. I'm developing another solution for my server now (A ControlPanel for players with stats, cash, bans.. in asp.NET), but saki2fifty will have my total support for translating the plugin to PT-BR language, or a minimal dev helping (but i think he can develop better than I haha)

    HINT: Furmiga has tried to make MAC Address on MySQL Table, and i think this is a very useful feature! xD
