nm-settings-ifcfg-rhnm-settings-ifcfg-rh — Description of ifcfg-rh settings plugin |
NetworkManager is based on the concept of connection profiles that contain network configuration (see nm-settings(5) for details). The profiles can be stored in various formats. NetworkManager uses plugins for reading and writing the data. The plugins can be configured in NetworkManager.conf(5).
The ifcfg-rh plugin is used on the Fedora and Red Hat
Enterprise Linux distributions to read/write configuration from/to
the traditional /etc/sysconfig/network-scripts/ifcfg-* files.
Each NetworkManager connection maps to one ifcfg-* file, with
possible usage of keys-* for passwords, route-*
for static IPv4 routes and route6-* for static IPv6 routes.
The plugin currently supports reading and writing Ethernet, Wi-Fi, InfiniBand,
VLAN, Bond, Bridge, and Team connections. Unsupported connection types (such as
WWAN, PPPoE, VPN, or ADSL) are handled by keyfile plugin
(nm-settings-keyfile(5)).
The main reason for using ifcfg-rh plugin is the compatibility
with legacy configurations for ifup and ifdown
(initscripts).
The ifcfg-rh config format is a simple text file containing
VARIABLE="value" lines. The format is described in sysconfig.txt
of initscripts package. Note that the configuration files
may be sourced by initscripts, so they must be valid shell
scripts. That means, for instance, that # character can be used
for comments, strings with spaces must be quoted, special characters must be escaped,
etc.
Users can create or modify the ifcfg-rh connection files manually, even if that is not the recommended way of managing the profiles. However, if they choose to do that, they must inform NetworkManager about their changes (see monitor-connection-file in nm-settings(5), and nmcli con (re)load).

The UUID values in the config files must be unique. You can use uuidgen command line tool to generate such values. Alternatively, you can leave out UUID entirely. In that case NetworkManager will generate a UUID based on the file name.
The main differences of NetworkManager ifcfg-rh plugin and traditional initscripts are:
NM_CONTROLLED=yes|no |
NM_CONTROLLED is NetworkManager-specific variable used by NetworkManager for determining whether the device of the ifcfg file should be managed. NM_CONTROLLED=yes is supposed if the variable is not present in the file. Note that if you have more ifcfg files for a single device, NM_CONTROLLED=no in one of the files will cause the device not to be managed. The profile may not even be the active one. |
New variables |
NetworkManager has introduced some new variable, not present in initscripts, to be able to store data for its new features. The variables are marked as extensions in the tables below. |
Semantic change of variables |
NetworkManager had to slightly change the semantic for a few variables.
|
See the next section for detailed mapping of NetworkManager properties and ifcfg-rh variables. Variable names, format and usage differences in NetworkManager and initscripts are documented in the tables below.
ifcfg-rh plugin variables marked with (+) are NetworkManager specific extensions not understood by traditional initscripts.

The following settings are not supported by ifcfg-rh plugin:
adsl, bluetooth, ppp, pppoe, serial, generic, gsm, cdma, 802-11-olpc-mesh, wimax, vpn
Each secret property in a NetworkManager setting has an associated flags property that describes how to handle that secret. In the fcfg-rh plugin variables for secret flags have a _FLAGS suffix. The variables contain one or more of the following values (space separated). Missing (or empty) *_FLAGS variable means that the password is owned by NetworkManager.
user - a user-session secret agent is responsible for providing
and storing this secret; when it is required, agents will be asked to provide it.
ask - the associated password is not saved but it will be
requested from the user each time it is required.
unused - in some situations it cannot be automatically determined
that a secret is required or not. This flag hints that the secret is not required and should
not be requested from the user.
