rheinfall is a packet forwarder / generator application for Redox.
It bypasses most of Redox's network stack by writing directly to the network: scheme, i.e. the network driver currently in charge.
rheinfall's goal is to give a rough performance assessment for Redox's drivers, especially its new 10 Gbit/s ixgbe driver.
To run rheinfall on Redox, create the directory cookbook/recipes/rheinfall.
Add a file recipe.sh to this directory with the following content:
GIT=https://github.com/ackxolotl/rheinfall.git
Open filesystem.toml and add a new entry for rheinfall under userutils = {}:
rheinfall = {}
Run one of Redox's build commands, e.g. make qemu.
To mirror all received packets back on the link, run
sudo rheinfall
To generate 1,500 Byte packets, run
sudo rheinfall --generate
The packet size can be modified with the --size flag:
sudo rheinfall --generate --size 60
rheinfall currently supports a size of 60 or 1,500 Byte packets.
