NM-SETTINGS-IFCFG-RH(5) Configuration NM-SETTINGS-IFCFG-RH(5)
NAME
nm-settings-ifcfg-rh - Description of ifcfg-rh settings plugin
DESCRIPTION
NetworkManager is based on the concept of connection profiles that
contain network configuration (see nm-settings-nmcli(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).
FILE FORMAT
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 (for example via 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.
DIFFERENCES AGAINST INITSCRIPTS
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 and differences
NetworkManager changes the semantics for a few variables and there
are other behavioral differences.
o PEERDNS - initscripts interpret PEERDNS=no to mean "never touch
resolv.conf". NetworkManager interprets it to say "never add
automatic (DHCP, PPP, VPN, etc.) nameservers to resolv.conf".
o ONBOOT - initscripts use ONBOOT=yes to mark the devices that
are to be activated during boot. NetworkManager extends this to
also mean that this profile can be used for auto-connecting at
any time.
o BOOTPROTO - NetworkManager supports traditional values none
(static), dhcp. But it also allows additional values to enable
new addressing methods. They are autoip for IPv4 link-local
addressing using Avahi daemon and shared for connection
sharing. When shared is used, NetworkManager assigns the
interface 10.42.0.1, or it uses the first static address, if
configured.
o HWADDR - initscripts compare the currently set hardware address
of a device, while NetworkManager considers the permanent one.
o NOZEROCONF - initscripts add an on-link route to 169.254.0.0/16
for ethernet profiles that don't explicitly opt-out by setting
NOZEROCONF variable. NetworkManager does not do that. Instead a
static, manual route with scope=253 (link) should be added to
get that behavior.
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.

|mac-address | HWADDR | | IBoIP 20-byte |
| | | | hardware address |
| | | | of the device |
| | | | (in traditional |
| | | | hex-digits-and-colons |
| | | | notation). Note |
| | | | that for |
| | | | initscripts this |
| | | | is the current |
| | | | MAC address of |
| | | | the device as |
| | | | found during |
| | | | ifup. For |

| | | | permanent MAC |
| | | | address exists, |
| | | | the MAC address |
| | | | initially |
| | | | configured on |
| | | | the device. |

|p-key | PKEY_ID or | PKEY=no | InfiniBand P_Key. The value can be a hex number prefixed with "0x" |

| | (requires | | specified. Note that ifcfg-rh format will always automatically set |
| | PKEY=yes) | | the full membership flag 0x8000 for the PKEY_ID variable. To |
| | | | express IDs without the full membership flag, use PKEY_ID_NM. Note |
| | | | that kernel internally treats the interface as having the full |
| | | | membership flag set, this mainly affects the interface name. For |
| | | | the ifcfg file to be supported by initscripts' ifup-ib, the |
| | | | DEVICE= must always be set. NetworkManager does not require that. |

|data | NM_USER_* | | each key/value |

| | | | name composed by |
| | | | concatenating |
| | | | NM_USER_ with |
| | | | the encoded key. |
| | | | The key is |
| | | | encoded by |
| | | | substituting |
| | | | lowercase |
| | | | letters with |
| | | | uppercase and |
| | | | prepending |
| | | | uppercase |

| | | | If VLAN_ID is |
| | | | not set, it is |
| | | | attempted to be |
| | | | detected from |
| | | | the suffix of |
| | | | DEVICE=. Note |
| | | | that older |
| | | | versions of |
| | | | NetworkManager |
| | | | had a bug where |
| | | | they would |
| | | | prefer the |
| | | | detected ID from |
| | | | the DEVICE over |
| | | | VLAN_ID. |
+---------------------+---------------------------+---------+--------------------------------------+
|flags | GVRP, MVRP, | | VLAN flags. |
| | VLAN_FLAGS | | |

| | | | Example: |
| | | | VLAN_EGRESS_PRIORITY_MAP=5:4,4:1,3:7 |
+---------------------+---------------------------+---------+--------------------------------------+
|interface-name | PHYSDEV and VLAN_ID, or | | VLAN interface name. If all |
| | DEVICE | | variables are set, parent device |
| | | | from PHYSDEV takes precedence over |
| | | | DEVICE, but VLAN id from DEVICE |
| | | | takes precedence over VLAN_ID. |
| | | | |
| | | | Example: PHYSDEV=eth0, VLAN_ID=12; |
| | | | or DEVICE=eth0.12 |

Secret flags
Each secret property in a NetworkManager setting has an associated
flags property that describes how to handle that secret. In the
ifcfg-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.
o 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.
o ask - the associated password is not saved but it will be requested
from the user each time it is required.
o 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.
