Where NetworkManager stores settings (SOLVED)

NetworkManager Configuration Files

NetworkManager supports various plug-ins that can define new locations for storing configuration information.

The main configuration file for NetworkManager, which is usually changed, is /etc/NetworkManager/NetworkManager.conf. You can view its contents with the following command:

cat /etc/NetworkManager/NetworkManager.conf

In addition to this file, NetworkManager settings can be saved in the /etc/NetworkManager/conf.d and /usr/lib/NetworkManager/conf.d directories.

For a list of all NetworkManager settings, taking into account all configuration files, run the command:

NetworkManager --print-config

Where NetworkManager stores network connection settings

NetworkManager stores the settings for each connection in separate text files with the .nmconnection extension. A typical storage location for configuration files is /var/run/NetworkManager/system-connections. In addition to it, files with connections can be located in other places defined by NetworkManager plugins, for example, settings for network connections via Bluetooth can be stored in the /etc/NetworkManager/NetworkManager.conf folder. The NetworkManager configuration file is /etc/NetworkManager/NetworkManager.conf. Besides these main locations, there may be other paths that are specific to Linux distributions.

To list all network connections and the location of their configuration files, run the command:

nmcli -f NAME,DEVICE,FILENAME connection show

All NetworkManager configuration files

So, the configuration files for NetworkManager are as follows:

• /etc/NetworkManager/NetworkManager.conf – main configuration file
• /etc/NetworkManager/conf.d – directory with configuration files
• /usr/lib/NetworkManager/conf.d – system directory with configuration files (for example, file /usr/lib/NetworkManager/conf.d/20-connectivity.conf)
• /var/lib/NetworkManager/NetworkManager-intern.conf – internal configuration file. This file is written and read by NetworkManager, and its configuration values are merged with the configuration from NetworkManager.conf. Changes made to this file will be overwritten
• /var/lib/NetworkManager/NetworkManager.state – file with a set of states
• /etc/NetworkManager/system-connections/ – directory where wired and wireless connections are stored
• /var/run/NetworkManager/system-connections/ – directory with some types of connections, for example, Internet via Bluetooth modem
• /var/lib/NetworkManager/
• /etc/NetworkManager/dispatcher.d/
• /etc/NetworkManager/dnsmasq.d/
• /etc/NetworkManager/dnsmasq-shared.d/
