Introduction
The C3 recovery tool is meant to help engineers verify and reset the basic WAN, LAN and WIFI configurations of the C3 appliance.
The tool is started for the C3 command line interface and is comprised of 2 parts:
- A set of health checks
- A list of recovery options
This tool is available from software version 4.0.7 onwards until version 4.8.4. It is not available in version 5.0 and upwards.
How to use it
The access to the C3 command line interface can be carried out in one of 2 ways:
- Connecting a display (VGA or HDMI depending on the C3 model) and a USB keyboard to the C3
- Connecting either to the LAN port or WiFi to the C3 LAN IP (default is 172.16.0.1), using and SSH Client, such as putty.
Log in to the C3 using the administrator credentials (default is username: c3; password: root).
To start the recovery tool: sudo c3-recovery.
Choose option “1”, to diagnose any configuration problem.
The diagnose part of the utility will check:
- If the br0 interface exists, is up with an assigned IP address
- The C3 WIFI, if it exists, it will check if the hostapd service is alive and running
- Check for conficts between the WAN and LAN subnets
Press any key to go back and then press “2” to enter recovery mode:
Press the desired option, to restore the default settings for the Wan, Lan ports or WIFI configuration.
Please note that restoring WIFI settings will enable the C3 WIFI (if it was disabled) and restore the SSID and password to the default values (c3edu.online/mydemokey).
The tool is exited by going back to the initial menu and pressing “3”.
