LPX
Avoid NettyCrashers, prevents netty threads to be blocked by exploits without using any ViaVersion fork;- AntiCheat-Fix blocks a few packets which cause anti-cheats to make the server use a lot of CPU;
- Dependency Free, doesn't require any dependency;
- Advanced Packet Injection, packets are analyzed and blocked before the server could decode them in a different way compared to any other anti-exploit;
- Highly configurable, easy, and detailed configuration anticheat-style;
- GUI for recent alerts;
- Packet logger with maximum files creation to avoid huge memory usage (toggleable);
- 1.8-1.18.2 Compatibility on paper and related forks;
- Frequent updates when a new exploit is detected;
- Printer/Schematica compatibility with API or semi-automatic system;
WHY LPX?
- UNIQUE FIX FOR NETTY CRASHERS, few rare clients, like GasClient, have NettyCrasher exploits, one type of exploit that doesn't affect the server's TPS but Netty's threads. A NettyCrasher makes Netty's threads busy when a packet gets decoded, so the server crashes and doesn't listen for any packet anymore. LPX is the only anti-exploit having this check without the use of any strange ViaVersion fork or Spigot fork.
- Custom Injection and no dependency required, LPX uses a unique way to inject compared to other anti-exploits, this guarantes high performance without the use of Reflections to read packets.
- Smooth Packet Limiter, Usually, anti-exploits don't encourage the use of packet limiters because it could cause issues with players having bad connections. LPX has an accurate way to count spam packets and has a fully working VL system to prevent false flags when players lag. If any false is detected, the config can be easily edited to fix false flags.
- Printer/Schematica Compatibility, usually packet limiters plugins causes incompatibility issues with this mods, LPX has a very useful automatic system that detects when a player started using printer mode and that guarantees no false kicks. There is also the option to use the API.
- Advanced Packet Logger, if your server is attacked with a packet exploit you can log every packet sent from any player to understand what type of exploit did he use and we can fix it in a few days. Packet Logger can be disabled, configured, and doesn't take too much memory because of automatic old file removal.
- Easy and detailed configuration, you can edit almost everything while you detect false-flags, you can choose to enable/disable kicks for every check, enable/disable specific checks and change EVERY VALUE used in the code.
