dumdumd

High performance UDP/TCP server that... just drops/reflects everything you send to it

Requirements

dumdumd requires a couple of libraries beside a normal C compiling environment with autoconf, automake, libtool and pkgconfig.

  • libev-dev || libuv1-dev
  • libssl-dev
  • libevent-dev
  • libnghttp2-dev

Build

sh autogen.sh
./configure
make

Usage

src/dumdumd -h

Docker usage

docker build -t dumdumd .
docker run -ti --init --network=host dumdumd -h

Optional parameter --network=host disables Docker networking. This improves performance when testing over physical network interfaces.

Optional parameters -ti --init make terminal work as you would expect, namely SIGINT from Control+C gets propagated to dumdumd.
