# Configuration Settings

802-1x setting

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    name
    string
    802-1x
| 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.
    eap
    array of string
    []
| The allowed EAP method to be used when authenticating to the network with 802.1x. Valid methods are: 'leap', 'md5', 'tls', 'peap', 'ttls', and 'fast'. Each method requires different configuration using the properties of this setting; refer to wpa_supplicant documentation for the allowed combinations.
    identity
    string
| Identity string for EAP authentication methods. Often the user's user or login name.
    anonymous-identity
    string
| Anonymous identity string for EAP authentication methods. Used as the unencrypted identity with EAP types that support different tunneled identity like EAP-TTLS.

When using the blob scheme (which is backwards compatible with NM 0.7.x) this property should be set to the certificate's DER encoded data. When using the path scheme, this property should be set to the full UTF-8 encoded path of the certificate, prefixed with the string 'file://' and ending with a terminating NULL byte. This property can be unset even if the EAP method supports CA certificates, but this allows man-in-the-middle attacks and is NOT recommended.
    ca-path
    string
| UTF-8 encoded path to a directory containing PEM or DER formatted certificates to be added to the verification chain in addition to the certificate specified in the 'ca-cert' property.
    subject-match

When using the path scheme, this property should be set to the full UTF-8 encoded path of the certificate, prefixed with the string 'file://' and ending with a terminating NULL byte.
    phase1-peapver
    string
| Forces which PEAP version is used when PEAP is set as the EAP method in 'eap' property. When unset, the version reported by the server will be used. Sometimes when using older RADIUS servers, it is necessary to force the client to use a particular PEAP version. To do so, this property may be set to '0' or '1' to force that specific PEAP version.
    phase1-peaplabel
    string
| Forces use of the new PEAP label during key derivation. Some RADIUS servers may require forcing the new PEAP label to interoperate with PEAPv1. Set to '1' to force use of the new PEAP label. See the wpa_supplicant documentation for more details.
    phase1-fast-provisioning
    string
| Enables or disables in-line provisioning of EAP-FAST credentials when FAST is specified as the EAP method in the #NMSetting8021x:eap property.

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. 'disabled' means IPv4 will not be used on this 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', 'link-local', or 'disabled' methods as there is no upstream 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', 'link-local', or 'disabled' methods as there is no upstream network.

    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', 'link-local', or 'disabled' methods as addressing is either automatic or disabled 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', 'link-local', or 'disabled', methods as there is no upstream network.

| 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 nameservers and search domains specified in the 'dns' and 'dns-search' properties, if any, are used.

    string
| A string sent to the DHCP server to identify the local machine which the DHCP server may use to customize the DHCP lease and options.
    dhcp-send-hostname
    boolean
    TRUE
| If TRUE, a hostname is 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. If the 'dhcp-hostname' property is empty and this property is TRUE, the current persistent hostname of the computer is sent.
    dhcp-hostname
    string
| If the 'dhcp-send-hostname' property is TRUE, then the specified name will be sent to the DHCP server when acquiring a lease.
    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.
    may-fail
    boolean
    TRUE
| If TRUE, allow overall network configuration to proceed even if IPv4 configuration times out. Note that at least one IP configuration must succeed or overall network configuration will still fail. For example, in IPv6-only networks, setting this property to TRUE allows the overall network configuration to succeed if IPv4 configuration fails but IPv6 configuration completes successfully.

    []
| 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 (byte array, uint32, byte array)
    []
| Array of IPv6 address structures. Each IPv6 address structure is composed of 3 members, the first being a byte array containing the IPv6 address (network byte order), the second a 32-bit integer containing the IPv6 address prefix, and the third a byte array containing the IPv6 address (network byte order) of the gateway associated with this address, if any. If no gateway is given, the third element should be given as all zeros. 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.

    array of (byte array, uint32, byte array, uint32)
    []
| Array of IPv6 route structures. Each IPv6 route structure is composed of 4 members; the first being the destination IPv6 network or address (network byte order) as a byte array, the second the destination network or address IPv6 prefix, the third being the next-hop IPv6 address (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 because there is no upstream network.
    ignore-auto-routes
    boolean
    FALSE

| When the method is set to 'auto' or 'dhcp' and this property is set to TRUE, automatically configured nameservers and search domains are ignored and only nameservers and search domains specified in the 'dns' and 'dns-search' properties, if any, are used.
    never-default
    boolean
    FALSE
| If TRUE, this connection will never be the default IPv6 connection, meaning it will never be assigned the default IPv6 route by NetworkManager.
    may-fail
    boolean
    TRUE
| If TRUE, allow overall network configuration to proceed even if IPv6 configuration times out. Note that at least one IP configuration must succeed or overall network configuration will still fail. For example, in IPv4-only networks, setting this property to TRUE allows the overall network configuration to succeed if IPv6 configuration fails but IPv4 configuration completes successfully.
    ip6-privacy
    int32
    -1
| Configure IPv6 Privacy Extensions for SLAAC, described in RFC4941. If enabled, it makes the kernel generate a temporary IPv6 address in addition to the public one generated from MAC address via modified EUI-64. This enhances privacy, but could cause problems in some applications, on the other hand. The permitted values are: 0: disabled, 1: enabled (prefer public address), 2: enabled (prefer temporary addresses).

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.

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.
    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.
