number string Number to dial when establishing a PPP data session with the CDMA-based mobile broadband network. If not specified, the default number (#777) is used when required.
username string Username used to authenticate with the network, if required. Note that many providers do not require a username or accept any username.
password string Password used to authenticate with the network, if required. Note that many providers do not require a password or accept any password.

Setting name: 'connection'

Key Name Value Type Default Value Value Description
name string connection The setting's name; these names are defined by the specification and cannot be changed after the object has been created. Each setting class has a name, and all objects of that class share the same name.
id string User-readable connection identifier/name. Must be one or more characters and may change over the lifetime of the connection if the user decides to rename it.
uuid string Universally unique connection identifier. Must be in the format '2815492f-7e56-435e-b2e9-246bd7cdc664' (ie, contains only hexadecimal characters and '-'). The UUID should be assigned when the connection is created and never changed as long as the connection stilla pplies to the same network. For example, it should not be changed when the user changes the connection's 'id', but should be recreated when the WiFi SSID, mobile broadband network provider, or the connection type changes.
type string Base type of the connection. For hardware-dependent connections, should contain the setting name of the hardware-type specific setting (ie, '802-3-ethernet' or '802-11-wireless' or 'bluetooth', etc), and for non-hardware dependent connections like VPN or otherwise, should contain the setting name of that setting type (ie, 'vpn' or 'bridge', etc).
autoconnect boolean FALSE If TRUE, NetworkManager will activate this connection when its network resources are available. If FALSE, the connection must be manually activated by the user or some other mechanism.
timestamp uint64 0 Timestamp (in seconds since the Unix Epoch) that the connection was last successfully activated. Settings services should update the connection timestamp periodically when the connection is active to ensure that an active connection has the latest timestamp.
read-only boolean FALSE If TRUE, the connection is read-only and cannot be changed by the user or any other mechanism. This is normally set for system connections whose plugin cannot yet write updated connections back out.

Setting name: 'gsm'

Key Name Value Type Default Value Value Description
name string gsm The setting's name; these names are defined by the specification and cannot be changed after the object has been created. Each setting class has a name, and all objects of that class share the same name.

username string Username used to authenticate with the network, if required. Note that many providers do not require a username or accept any username.
password string Password used to authenticate with the network, if required. Note that many providers do not require a password or accept any password.
apn string The GPRS Access Point Name specifying the APN used when establishing a data session with the GSM-based network. The APN often determines how the user will be billed for their network usage and whether the user has access to the Internet or just a provider-specific walled-garden, so it is important to use the correct APN for the user's mobile broadband plan.
network-id string The Network ID (GSM LAI format, ie MCC-MNC) to force specific network registration. If the Network ID is specified, NetworkManager will attempt to force the device to register only on the specified network. This can be used to ensure that the device does not roam when direct roaming control of the device is not otherwise possible.
network-type int32 0 Network preference to force the device to only use specific network technologies. The permitted values are: -1: any, 0: 3G only, 1: GPRS/EDGE only, 2: prefer 3G, and 3: prefer 2G. Note that not all devices allow network preference control.
band int32 0 Band (currently unused)
pin string If the SIM is locked with a PIN it must be unlocked before any other operations are requested. Specify the PIN here to allow operation of the device.
puk string If the PIN is incorrectly entered too many times, the PUK (PIN Unlock Code) is required before the device becomes operational. It's usually best not to enter the PUK due to the risk of completely locking your SIM by entering a wrong PUK too many times.

Setting name: 'ipv4'

Key Name Value Type Default Value Value Description
name string ipv4 The setting's name; these names are defined by the specification and cannot be changed after the object has been created. Each setting class has a name, and all objects of that class share the same name.
method string IPv4 configuration method. If 'auto' is specified then the appropriate automatic method (DHCP, PPP, etc) is used for the interface and most other properties can be left unset. If 'link-local' is specified, then a link-local address in the 169.254/16 range will be assigned to the interface. If 'manual' is specified, static IP addressing is used and at least one IP address must be given in the 'addresses' property. If 'shared' is specified (indicating that this connection will provide network access to other computers) then the interface is assigned an address in the 10.42.x.1/24 range and a DHCP and forwarding DNS server are started, and the interface is NAT-ed to the current default network connection. This property must be set.
dns array of uint32 List of DNS servers (network byte order). For the 'auto' method, these DNS servers are appended to those (if any) returned by automatic configuration. DNS servers cannot be used with the 'shared' or 'link-local' methods as there is no usptream network. In all other methods, these DNS servers are used as the only DNS servers for this connection.
dns-search array of string List of DNS search domains. For the 'auto' method, these search domains are appended to those returned by automatic configuration. Search domains cannot be used with the 'shared' or 'link-local' methods as there is no upstream network. In all other methods, these search domains are used as the only search domains for this connection.
addresses array of array of uint32 Array of IPv4 address structures. Each IPv4 address structure is composed of 3 32-bit values; the first being the IPv4 address (network byte order), the second the prefix (1 - 32), and last the IPv4 gateway (network byte order). The gateway may be left as 0 if no gateway exists for that subnet. For the 'auto' method, given IP addresses are appended to those returned by automatic configuration. Addresses cannot be used with the 'shared' or 'link-local' methods as the interface is automatically assigned an address with these methods.
routes array of array of uint32 Array of IPv4 route structures. Each IPv4 route structure is composed of 4 32-bit values; the first being the destination IPv4 network or address (network byte order), the second the destination network or address prefix (1 - 32), the third being the next-hop (network byte order) if any, and the fourth being the route metric. For the 'auto' method, given IP routes are appended to those returned by automatic configuration. Routes cannot be used with the 'shared' or 'link-local' methods as there is no upstream network.
ignore-auto-routes boolean FALSE When the method is set to 'auto' and this property to TRUE, automatically configured routes are ignored and only routes specified in the 'routes' property, if any, are used.
ignore-auto-dns boolean FALSE When the method is set to 'auto' and this property to TRUE, automatically configured nameservers and search domains are ignored and only namservers and search domains specified in the 'dns' and 'dns-search' properties, if any, are used.
dhcp-client-id string A string sent to the DHCP server to identify the local machine which the DHCP server may use to cusomize the DHCP lease and options.
dhcp-hostname string A hostname to be sent to the DHCP server when acquiring a lease. Some DHCP servers use this hostname to update DNS databases, essentially providing a static hostname for the computer.
never-default boolean FALSE If TRUE, this connection will never be the default IPv4 connection, meaning it will never be assigned the default route by NetworkManager.

require-mppe boolean FALSE If TRUE, MPPE (Microsoft Point-to-Point Encrpytion) will be required for the PPP session. If either 64-bit or 128-bit MPPE is not available the session will fail. Note that MPPE is not used on mobile broadband connections.
require-mppe-128 boolean FALSE If TRUE, 128-bit MPPE (Microsoft Point-to-Point Encrpytion) will be required for the PPP session, and the 'require-mppe' property must also be set to TRUE. If 128-bit MPPE is not available the session will fail.
mppe-stateful boolean FALSE If TRUE, stateful MPPE is used. See pppd documentation for more information on stateful MPPE.
crtscts boolean FALSE If TRUE, specify that pppd should set the serial port to use hardware flow control with RTS and CTS signals. This value should normally be set to FALSE.
baud uint32 0 If non-zero, instruct pppd to set the serial port to the specified baudrate. This value should normally be left as 0 to automatically choose the speed.
mru uint32 0 If non-zero, instruct pppd to request that the peer send packets no larger than the specified size. If non-zero, the MRU should be between 128 and 16384.

band string 802.11 frequency band of the network. One of 'a' for 5GHz 802.11a or 'bg' for 2.4GHz 802.11. This will lock associations to the WiFi network to the specific band, i.e. if 'a' is specified, the device will not associate with the same network in the 2.4GHz band even if the network's settings are compatible. This setting depends on specific driver capability and may not work with all drivers.
channel uint32 0 Wireless channel to use for the WiFi connection. The device will only join (or create for Ad-Hoc networks) a WiFi network on the specified channel. Because channel numbers overlap between bands, this property also requires the 'band' property to be set.
bssid byte array If specified, directs the device to only associate with the given access point. This capability is highly driver dependent and not supported by all devices. Note: this property does not control the BSSID used when creating an Ad-Hoc network and is unlikely to in the future.
rate uint32 0 If non-zero, directs the device to only use the specified bitrate for communication with the access point. Units are in Kb/s, ie 5500 = 5.5 Mbit/s. This property is highly driver dependent and not all devices support setting a static bitrate.

mac-address byte array If specified, this connection will only apply to the WiFi device whose MAC address matches. This property does not change the MAC address of the device (known as MAC spoofing).
mtu uint32 0 If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple Ethernet frames.
seen-bssids array of string A list of BSSIDs (each BSSID formatted as a MAC address like '00:11:22:33:44:55') that have been detected as part of the WiFI network. The settings service will usually populate this property by periodically asking NetworkManager what the device's current AP is while connected to the network (or monitoring the device's 'active-ap' property) and adding the current AP's BSSID to this list. This list helps NetworkManager find hidden APs by matching up scan results with the BSSIDs in this list.
security string If the wireless connection has any security restrictions, like 802.1x, WEP, or WPA, set this property to '802-11-wireless-security' and ensure the connection contains a valid 802-11-wireless-security setting.

One of 'open' for Open System, 'shared' for Shared Key, or 'leap' for Cisco LEAP. When using Cisco LEAP (ie, key-mgmt = 'ieee8021x' and auth-alg = 'leap') the 'leap-username' and 'leap-password' properties must be specified.
proto array of string List of strings specifying the allowed WPA protocol versions to use. Each element may be one 'wpa' (allow WPA) or 'rsn' (allow WPA2/RSN). If not specified, both WPA and RSN connections are allowed.

psk string Pre-Shared-Key for WPA networks. If the key is 64-characters long, it must contain only hexadecimal characters and is interpreted as a hexadecimal WPA key. Otherwise, the key must be between 8 and 63 ASCII characters (as specified in the 802.11i standard) and is interpreted as a WPA passphrase, and is hashed to derive the actual WPA-PSK used when connecting to the WiFi network.
leap-password string The login password for legacy LEAP connections (ie, key-mgmt = 'ieee8021x' and auth-alg = 'leap').
wep-key-type uint32 0 Controls the interpretation of WEP keys. Allowed values are 1 (interpret WEP keys as hexadecimal or ASCII keys) or 2 (interpret WEP keys as WEP Passphrases). If set to 1 and the keys are hexadecimal, they must be either 10 or 26 characters in length. If set to 1 and the keys are ASCII keys, they must be either 5 or 13 characters in length. If set to 2, the passphrase is hashed using the de-facto MD5 method to derive the actual WEP key.
