Automated Configuration of CeroWrt

CeroWrt uses the LuCi GUI (from OpenWrt) to make it easy to tweak most every part of the CeroWrt configuration.

However, when testing the software, it’s convenient to have a script that will issue the same set of configuration commands so that a fresh firmware installation can be brought to a consistent state in a single step. The following script will configure a number of interesting aspects of CeroWrt, including:

  • Set up the ge00/WAN interface to connect to your provider
  • Update the software packages
  • Update the root password
  • Set the time zone
  • Enable SNMP for traffic monitoring and measurements
  • Enable NetFlow export for traffic analysis
  • Enable mDNS/ZeroConf on the ge00 (WAN) interface
  • Change default IP addresses and subnets for interfaces
  • Change default DNS names
  • Set the SQM (Smart Queue Management) parameters
  • Set the radio channels
  • Set wireless SSID names
  • Set the wireless security credentials

The script has a set of lines for each task. They’re all optional, because they’re all commented out. If you wish to perform one of these, fill in any of the values, then uncomment the affected lines.

How can I get this script?

The config-cerowrt.sh script is now part of the CeroWrtScripts bundle. A direct link to the script is: https://github.com/richb-hanover/CeroWrtScripts/blob/master/config-cerowrt.sh But it’s easier to use the script if you git clone it to your router as described on the CeroWrtScripts page.
