The profiles can be stored in various formats\&. NetworkManager uses plugins for reading and writing the data\&. The plugins can be configured in \fBNetworkManager.conf\fR(5)\&. .PP The \fIkeyfile\fR plugin is the generic plugin that supports all the connection types and capabilities that NetworkManager has\&. The files are in a \&.ini\-style format and located in /etc/NetworkManager/system\-connections/, /usr/lib/NetworkManager/system\-connections/ and /run/NetworkManager/system\-connections/\&. This plugin is always enabled and will automatically be used to store any connections that are not supported by any other active plugin\&. For security, it will ignore files that are readable or writable by any user other than \*(Aqroot\*(Aq since private keys and passphrases may be stored in plaintext inside the file\&. .SH "FILE FORMAT" .PP The \fIkeyfile\fR config format is a simple \&.ini\-style format\&. It consists of sections (groups) of key\-value pairs\&. Each section corresponds to a setting name as described in the settings specification (\fBnm-settings\fR(5))\&. Each configuration key/value pair in the section is one of the properties listed in the settings specification\&. The majority of properties of the specification is written in the same format into the \fIkeyfile\fR too\&. However some values are inconvenient for people to use\&. These are stored in the files in more readable ways\&. These properties are described below\&. An example could be IP addresses that are not written as integer arrays, but more reasonably as "1\&.2\&.3\&.4/12 1\&.2\&.3\&.254"\&. More information of the generic key file format can be found at \m[blue]\fBGLib key file format\fR\m[]\&\s-2\u[1]\d\s+2 (Lines beginning with a \*(Aq#\*(Aq are comments, lists are separated by character ; etc\&.)\&. .PP Users can create or modify the \fIkeyfile\fR 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 \fInmcli con (re)load\fR)\&. .PP \fBExamples of keyfile configuration\fR. .sp .if n \{\ .RS 4 .\} .nf \fBA sample configuration for an ethernet network:\fR [connection] id=Main eth0 uuid=27afa607\-ee36\-43f0\-b8c3\-9d245cdc4bb3 type=802\-3\-ethernet autoconnect=true [ipv4] method=auto [802\-3\-ethernet] mac\-address=00:23:5a:47:1f:71 .fi .if n \{\ .RE .\} .sp .if n \{\ .RS 4 .\} .nf \fBA sample configuration for WPA\-EAP (PEAP with MSCHAPv2) and always\-ask secret:\fR [connection] id=CompanyWIFI uuid=cdac6154\-a33b\-4b15\-9904\-666772cfa5ee type=wifi autoconnect=false [wifi] ssid=CorpWLAN mode=infrastructure security=802\-11\-wireless\-security [wifi\-security] key\-mgmt=wpa\-eap [ipv4] method=auto [ipv6] method=auto [802\-1x] eap=peap; identity=joe ca\-cert=/home/joe/\&.cert/corp\&.crt phase1\-peapver=1 phase2\-auth=mschapv2 password\-flags=2 .fi .if n \{\ .RE .\} .sp .if n \{\ .RS 4 .\} .nf \fBA sample configuration for openvpn:\fR [connection] id=RedHat\-openvpn uuid=7f9b3356\-b210\-4c0e\-8123\-bd116c9c280f type=vpn timestamp=1385401165 [vpn] service\-type=org\&.freedesktop\&.NetworkManager\&.openvpn connection\-type=password password\-flags=3 remote=ovpn\&.my\-company\&.com cipher=AES\-256\-CBC reneg\-seconds=0 port=443 username=joe ca=/etc/openvpn/ISCA\&.pem tls\-remote=ovpn\&.my\-company\&.com [ipv6] method=auto [ipv4] method=auto ignore\-auto\-dns=true never\-default=true .fi .if n \{\ .RE .\} .sp .if n \{\ .RS 4 .\} .nf \fBA sample configuration for a bridge and a bridge port:\fR [connection] [connection] id=MainBridge id=br\-port\-1 uuid=171ae855\-a0ab\-42b6\-bd0c\-60f5812eea9d uuid=d6e8ae98\-71f8\-4b3d\-9d2d\-2e26048fe794 interface\-name=MainBridge interface\-name=em1 type=bridge type=ethernet master=MainBridge [bridge] slave\-type=bridge interface\-name=MainBridge .fi .if n \{\ .RE .\} .sp .if n \{\ .RS 4 .\} .nf \fBA sample configuration for a VLAN:\fR [connection] id=VLAN for building 4A uuid=8ce1c9e0\-ce7a\-4d2c\-aa28\-077dda09dd7e interface\-name=VLAN\-4A type=vlan [vlan] interface\-name=VLAN\-4A parent=eth0 id=4 .fi .if n \{\ .RE .\} .SH "DETAILS" .PP \fIkeyfile\fR plugin variables for the majority of NetworkManager properties have one\-to\-one mapping\&. It means a NetworkManager property is stored in the keyfile as a variable of the same name and in the same format\&. There are several exceptions to this rule, mainly for making keyfile syntax easier for humans\&. The exceptions handled specially by \fIkeyfile\fR plugin are listed below\&. Refer to \fBnm-settings\fR(5) for all available settings and properties and their description\&. .PP \fBName aliases\fR. Some of the NetworkManager setting names are somewhat hard to type or remember\&. Therefore \fIkeyfile\fR introduces aliases that can be used instead of the names\&. .RS 4 \fIsetting name keyfile alias\fR .RE .RS 4 802\-3\-ethernet = ethernet .RE .RS 4 802\-11\-wireless = wifi .RE .RS 4 802\-11\-wireless\-security = wifi\-security .RE .sp .it 1 an-trap .nr an-no-space-flag 1 .nr an-break-flag 1 .br .B Table\ \&1.\ \&802\-11\-wireless setting (section) .TS allbox tab(:); lB lB lB lB.
