Most of the LibreMesh configuration is handled by a unified configuration file placed on /etc/config/lime.
This file is part of the UCI database which unifies also most of the OpenWRT/LEDE configuration files.
The main configuration script of libremesh is named lime-config and can be invoked typing lime-config in the node’s root terminal.
In addition to /etc/config/lime there exist also /etc/config/lime-defaults.
If a configuration option is not found in config/lime, the config/lime-defaults one will be used when running the lime-config command.
lime config file
The idea behind this structure is that the user only modifies /etc/config/lime but never /etc/config/lime-defaults.
Once the file is modified the command lime-config must be run. To enable the changes you might reboot the node (reboot command) or execute reload_config.
For a detailed view of the config file options see config.
The networking options of config/lime are defined in two different blocks.
