Project Update

This project is no longer maintained and has been archived. It remains available for reference but will not receive further updates.

<p> High-Performance Source Engine Query Cacher for caching and responding A2S_INFO and A2S_PLAYER packets. </p> <p> Features: <ol> <li> Built on top of Netty. </li> <li> Uses Direct Buffers to minimize memory copy and garbage creation in JVM. </li> <li> Truely Asynchronous. </li> <li> Uses native Epoll Transport. </li> <li> In-Memory Cache for storing A2S_PLAYER challenge codes. </li> <li> Multi-threaded with configurable thread count for maximum performance </li> <li> Highly configurable using Configuration file or Process arguments. </li> </ol> </p>

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
