New CeroWrt Router scripts

I posted a set of scripts that people can use to test, configure and debug their CeroWrt router installations. CeroWrt router firmware is a test bed for learning about and eliminating bufferbloat.

The scripts are available on Github at https://github.com/richb-hanover/CeroWrtScripts. They include:

  • betterspeedtest.sh – a script that emulates the famous (but limited) speedtest.net. This script is better because it measures ping latency during the download and upload, and tells you how bad (or not) the bloat is in your network/router.

  • netperfrunner.sh – a script that emulates the RRUL test suite. It runs on the CeroWrt router (or your laptop) to measure the latency under heavy load.

  • config-cerowrt.sh and tunnelbroker.sh – two scripts for configuring a CeroWrt router to a consistent state after flashing new firmware.

  • cerostats.sh – a script that collects a number of configuration and operational stats that is useful for debugging.
