What is Darkstat ?
darkstat is a network statistics gatherer.
Effectively, it’s a packet sniffer which runs as a background process on a
cable/DSL router, gathers all sorts of useless but interesting statistics,
and serves them over HTTP.
Tracks traffic per host.
Tracks traffic per TCP and UDP port for each host.
Embedded web-server with deflate compression.
Asynchronous reverse DNS resolution using a child process.
Small. Portable. Single-threaded. Efficient.
