minecraft bot prevention

[will01mack]

So this one (or might have been multiple) botter has been on my mc server a few times in the past month or 2 and I need to stop them. Does anyone know of a plugin or something that I can use? Maybe some sort of verification system to join the server.

If the attack is small, an antibot such as JH_Antibot (created by a person that runs a bot attack platform) is enough. If you want to be able to resist large amounts of connections, I suggest using a Layer 7 firewall in order to limit syn connections.

I have such a firewall implementation done already. You can access it here. It's open-sourced:

If you're looking for something more advanced, you'd be looking at automatic whitelisting of verified players and potentially a queue system to block volumetric attacks from happening.

Thank you. How do I use the firewall on my server?

It's open source. Check the system, compile the plugin (optional) and run the script.

Ok, thank you.

I’d recommend that you start with at least an anti vpn as this will block simple spam attacks, after that if the problem is still occurring you may want to get a plug-in as suggested.
Even something as simple as not allowing players to type without moving can be a prevention for this but the bots will still be active on the server.
