We have completely re-engineered the backend of our DNS Leak Test to handle extreme loads. Moving away from Python-based packet sniffing, the new engine uses 'tcpdump' for C-based kernel-level filtering. This stream is piped directly into a lightweight parser and stored in Redis via Unix Sockets. The result is a monitoring system that processes thousands of queries per second with virtually 0% CPU impact.
Major architectural shift for our DNS Leak Test. Now utilizing kernel-level packet capture (tcpdump) piped to Redis for zero-latency tracking.
Highlights
- Kernel-level capture via tcpdump
- Zero-latency I/O piping
- Redis Unix Socket storage
- 99% reduction in CPU overhead
