Source Engine Query Cacher

Downloads

High-Performance Source Engine Query Cacher for caching and responding A2S_INFO and A2S_PLAYER packets.

Features:

  1. Built on top of Netty.
  2. Uses Direct Buffers to minimize memory copy and garbage creation in JVM.
  3. Truely Asynchronous.
  4. Uses native Epoll Transport.
  5. In-Memory Cache for storing A2S_PLAYER challenge codes.
  6. Multi-threaded with configurable thread count for maximum performance
  7. Highly configurable using Configuration file or Process arguments.

Requirements:

Java 11 and Linux Kernel 3.9+.

How to run:

  1. Download and Install Java 11.
  2. Download Source Engine Query Cacher Binary.
  3. Execute the following command: java -jar SourceEngineQueryCacher-1.6.6.jar
  4. Source Engine Query Cacher will start and display 'Server Started on Socket: IP:PORT'.
  5. Configure IPTables for routing Query Packets and everything is done.

Redirect Query Packets to Query Cacher in Linux using IPTables

iptables -t nat -A PREROUTING -p udp --dport 27015 --match string --algo kmp --hex-string '|FFFFFFFF54|' -j REDIRECT --to-ports 9110
iptables -t nat -A PREROUTING -p udp --dport 27015 --match string --algo kmp --hex-string '|FFFFFFFF55|' -j REDIRECT --to-ports 9110
iptables -t nat -A PREROUTING -p udp --dport 27015 --match string --algo kmp --hex-string '|FFFFFFFF41|' -j REDIRECT --to-ports 9110
