# Network Configuration Setting Specification

This part documents the properties and value types of each "Setting" object that composes the basic unit of NetworkManager configuration, the "Connection". Each Connection object is simply a dictionary mapping setting names (like "wimax" or "bluetooth") to a dictionary of key/value pairs that represents each itself.

## Configuration Settings

Table 1. 802-1x setting

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    altsubject-matches
    array of string
    []
| List of strings to be matched against the altSubjectName of the certificate presented by the authentication server. If the list is empty, no verification of the server certificate's altSubjectName is performed.
    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.
    ca-cert
    byte array
| Contains the CA certificate if used by the EAP method specified in the "eap" property. Certificate data is specified using a "scheme"; two are currently supported: blob and path. 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 NUL 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.
    client-cert
    byte array
| Contains the client certificate if used by the EAP method specified in the "eap" property. Certificate data is specified using a "scheme"; two are currently supported: blob and path. 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 NUL byte.

See the wpa_supplicant documentation for more details.
    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-peapver
    string
| Forces which PEAP version is used when PEAP is set as the EAP method in the "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.
    phase2-altsubject-matches
    array of string
    []

Certificate data is specified using a "scheme"; two are currently supported: blob and path. 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 NUL 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.
    phase2-private-key
    byte array
| Contains the "phase 2" inner private key when the "phase2-auth" or "phase2-autheap" property is set to "tls". Key data is specified using a "scheme"; two are currently supported: blob and path. When using the blob scheme and private keys, this property should be set to the key's encrypted PEM encoded data. When using private keys with the path scheme, this property should be set to the full UTF-8 encoded path of the key, prefixed with the string "file://" and ending with a terminating NUL byte. When using PKCS#12 format private keys and the blob scheme, this property should be set to the PKCS#12 data and the "phase2-private-key-password" property must be set to password used to decrypt the PKCS#12 certificate and key. When using PKCS#12 files and the path scheme, this property should be set to the full UTF-8 encoded path of the key, prefixed with the string "file://" and and ending with a terminating NUL byte, and as with the blob scheme the "phase2-private-key-password" property must be set to the password used to decode the PKCS#12 private key and certificate.
    phase2-private-key-password
    string
| The password used to decrypt the "phase 2" private key specified in the "phase2-private-key" property when the private key either uses the path scheme, or is a PKCS#12 format key.

When using the blob scheme and private keys, this property should be set to the key's encrypted PEM encoded data. When using private keys with the path scheme, this property should be set to the full UTF-8 encoded path of the key, prefixed with the string "file://" and ending with a terminating NUL byte. When using PKCS#12 format private keys and the blob scheme, this property should be set to the PKCS#12 data and the "private-key-password" property must be set to password used to decrypt the PKCS#12 certificate and key. When using PKCS#12 files and the path scheme, this property should be set to the full UTF-8 encoded path of the key, prefixed with the string "file://" and and ending with a terminating NUL byte, and as with the blob scheme the "private-key-password" property must be set to the password used to decode the PKCS#12 private key and certificate. WARNING: "private-key" is not a "secret" property, and thus unencrypted private key data using the BLOB scheme may be readable by unprivileged users. Private keys should always be encrypted with a private key password to prevent unauthorized access to unencrypted private key data.
    private-key-password
    string
| The password used to decrypt the private key specified in the "private-key" property when the private key either uses the path scheme, or if the private key is a PKCS#12 format key.

    system-ca-certs
    boolean
    FALSE
| When TRUE, overrides the "ca-path" and "phase2-ca-path" properties using the system CA directory specified at configure time with the --system-ca-path switch. The certificates in this directory are added to the verification chain in addition to any certificates specified by the "ca-cert" and "phase2-ca-cert" properties. If the path provided with --system-ca-path is rather a file name (bundle of trusted CA certificates), it overrides "ca-cert" and "phase2-ca-cert" properties instead (sets ca_cert/ca_cert2 options for wpa_supplicant).

    autoconnect-slaves
    NMSettingConnectionAutoconnectSlaves (int32)
| Whether or not slaves of this connection should be automatically brought up when NetworkManager activates this connection. This only has a real effect for master connections. The permitted values are: 0: leave slave connections untouched, 1: activate all the slave connections with this connection, -1: default. If -1 (default) is set, global connection.autoconnect-slaves is read to determine the real value. If it is default as well, this fallbacks to 0.

| The name of the network interface this connection is bound to. If not set, then the connection can be attached to any interface of the appropriate type (subject to restrictions imposed by other settings). For software devices this specifies the name of the created device. For connection types where interface names cannot easily be made persistent (e.g. mobile broadband or USB Ethernet), this property should not be used. Setting this property restricts the interfaces a connection can be used with, and if interface names change or are reordered the connection may be applied to the wrong interface.

Otherwise a user is allowed to access this connection if and only if they are in this list. Each entry is of the form "[type]:[id]:[reserved]"; for example, "user:dcbw:blah". At this time only the "user" [type] is allowed. Any other values are ignored and reserved for future use. [id] is the username that this permission refers to, which may not contain the ":" character. Any [reserved] information present must be ignored and is reserved for future use. All of [type], [id], and [reserved] must be valid UTF-8.
    read-only
    boolean
    FALSE
| FALSE if the connection can be modified using the provided settings service's D-Bus interface with the right privileges, or TRUE if the connection is read-only and cannot be modified.

    timestamp
    uint64
    0
| The time, in seconds since the Unix Epoch, that the connection was last _successfully_ fully activated. NetworkManager updates the connection timestamp periodically when the connection is active to ensure that an active connection has the latest timestamp. The property is only meant for reading (changes to this property will not be preserved).
    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).
    uuid
    string
| A universally unique identifier for the connection, for example generated with libuuid. It should be assigned when the connection is created, and never changed as long as the connection still applies to the same network. For example, it should not be changed when the "id" property or NMSettingIP4Config changes, but might need to be re-created when the Wi-Fi SSID, mobile broadband network provider, or "type" property changes. The UUID must be in the format "2815492f-7e56-435e-b2e9-246bd7cdc664" (ie, contains only hexadecimal characters and "-").
    zone
    string
| The trust level of a the connection. Free form case-insensitive string (for example "Home", "Work", "Public"). NULL or unspecified zone means the connection will be placed in the default zone as defined by the firewall.

This can be used to ensure that the device does not roam when direct roaming control of the device is not otherwise possible.
    number
    string
| Number to dial when establishing a PPP data session with the GSM-based mobile broadband network. Many modems do not require PPP for connections to the mobile network and thus this property should be left blank, which allows NetworkManager to select the appropriate settings automatically.
    password
    string
| The password used to authenticate with the network, if required. Many providers do not require a password, or accept any password. But if a password is required, it is specified here.
    password-flags
    NMSettingSecretFlags (uint32)
| Flags indicating how to handle the "password" property.
    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.
    pin-flags
    NMSettingSecretFlags (uint32)
| Flags indicating how to handle the "pin" property.

Table 12. infiniband setting

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    mac-address
    byte array
| If specified, this connection will only apply to the IPoIB device whose permanent MAC address matches. This property does not change the MAC address of the device (i.e. MAC spoofing).
    mtu
    uint32
    0
| If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple frames.
    name
    string
    infiniband
| The setting's name, which uniquely identifies the setting within the connection. Each setting type has a name unique to that type, for example "ppp" or "wireless" or "wired".
    p-key
    int32
    -1
| The InfiniBand P_Key to use for this device. A value of -1 means to use the default P_Key (aka "the P_Key at index 0"). Otherwise it is a 16-bit unsigned integer, whose high bit is set if it is a "full membership" P_Key.
    parent
    string
| The interface name of the parent device of this device. Normally NULL, but if the "p_key" property is set, then you must specify the base device by setting either this property or "mac-address".
    transport-mode
    string
| The IP-over-InfiniBand transport mode. Either "datagram" or "connected".

Table 13. ipv4 setting

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    address-data
    array of vardict
| Array of IPv4 addresses. Each address dictionary contains at least 'address' and 'prefix' entries, containing the IP address as a string, and the prefix length as a uint32. Additional attributes may also exist on some addresses.
    addresses
    array of array of uint32
    []
| Deprecated in favor of the 'address-data' and 'gateway' properties, but this can be used for backward-compatibility with older daemons. Note that if you send this property the daemon will ignore 'address-data' and 'gateway'. 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.
    dhcp-client-id
    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-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.
    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 NULL and this property is TRUE, the current persistent hostname of the computer is sent.
    dns
    array of uint32
    []
| Array of IP addresses of DNS servers (as network-byte-order integers)
    dns-search
    array of string
    []
| Array of DNS search domains.
    gateway
    string
| The gateway associated with this configuration. This is only meaningful if "addresses" is also set.
    ignore-auto-dns
    boolean
    FALSE
| When "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.
    ignore-auto-routes
    boolean
    FALSE
| When "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.
    may-fail
    boolean
    TRUE
| If TRUE, allow overall network configuration to proceed even if the configuration specified by this property 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 on the NMSettingIP4Config allows the overall network configuration to succeed if IPv4 configuration fails but IPv6 configuration completes successfully.
    method
    string
| IP configuration method. NMSettingIP4Config and NMSettingIP6Config both support "auto", "manual", and "link-local". See the subclass-specific documentation for other values. In general, for the "auto" method, properties such as "dns" and "routes" specify information that is added on to the information returned from automatic configuration. The "ignore-auto-routes" and "ignore-auto-dns" properties modify this behavior. For methods that imply no upstream network, such as "shared" or "link-local", these properties must be empty.
    name
    string
    ipv4
| The setting's name, which uniquely identifies the setting within the connection. Each setting type has a name unique to that type, for example "ppp" or "wireless" or "wired".
    never-default
    boolean
    FALSE
| If TRUE, this connection will never be the default connection for this IP type, meaning it will never be assigned the default route by NetworkManager.
    route-data
    array of vardict
| Array of IPv4 routes. Each route dictionary contains at least 'dest' and 'prefix' entries, containing the destination IP address as a string, and the prefix length as a uint32. Most routes will also have a 'gateway' entry, containing the gateway IP address as a string. If the route has a 'metric' entry (containing a uint32), that will be used as the metric for the route (otherwise NM will pick a default value appropriate to the device). Additional attributes may also exist on some routes.
    route-metric
    int64
    -1
| The default metric for routes that don't explicitly specify a metric. The default value -1 means that the metric is choosen automatically based on the device type. The metric applies to dynamic routes, manual (static) routes that don't have an explicit metric setting, address prefix routes, and the default route. Note that for IPv6, the kernel accepts zero (0) but coerces it to 1024 (user default). Hence, setting this property to zero effectively mean setting it to 1024. For IPv4, zero is a regular value for the metric.
    routes
    array of array of uint32
    []
| Deprecated in favor of the 'route-data' property, but this can be used for backward-compatibility with older daemons. Note that if you send this property the daemon will ignore 'route-data'. 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. If the metric is 0, NM will choose an appropriate default metric for the device. (There is no way to explicitly specify an actual metric of 0 with this property.)

Table 14. ipv6 setting

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    address-data
    array of vardict
| Array of IPv6 addresses. Each address dictionary contains at least 'address' and 'prefix' entries, containing the IP address as a string, and the prefix length as a uint32. Additional attributes may also exist on some addresses.
    addresses
    array of legacy IPv6 address struct (a(ayuay))
    []
| Deprecated in favor of the 'address-data' and 'gateway' properties, but this can be used for backward-compatibility with older daemons. Note that if you send this property the daemon will ignore 'address-data' and 'gateway'. Array of IPv6 address structures. Each IPv6 address structure is composed of an IPv6 address, a prefix length (1 - 128), and an IPv6 gateway address. The gateway may be zeroed out if no gateway exists for that subnet.
    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.
    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 NULL and this property is TRUE, the current persistent hostname of the computer is sent.
    dns
    array of byte array
    []
| Array of IP addresses of DNS servers (in network byte order)
    dns-search
    array of string
    []
| Array of DNS search domains.
    gateway
    string
| The gateway associated with this configuration. This is only meaningful if "addresses" is also set.
    ignore-auto-dns
    boolean
    FALSE
| When "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.
    ignore-auto-routes
    boolean
    FALSE
| When "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.
    ip6-privacy
    NMSettingIP6ConfigPrivacy (int32)
| 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: -1: unknown, 0: disabled, 1: enabled (prefer public address), 2: enabled (prefer temporary addresses). Having a per-connection setting set to "-1" (unknown) means fallback to global configuration "ipv6.ip6-privacy". If also global configuration is unspecified or set to "-1", fallback to read "/proc/sys/net/ipv6/conf/default/use_tempaddr".
    may-fail
    boolean
    TRUE
| If TRUE, allow overall network configuration to proceed even if the configuration specified by this property 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 on the NMSettingIP4Config allows the overall network configuration to succeed if IPv4 configuration fails but IPv6 configuration completes successfully.
    method
    string
| IP configuration method. NMSettingIP4Config and NMSettingIP6Config both support "auto", "manual", and "link-local". See the subclass-specific documentation for other values. In general, for the "auto" method, properties such as "dns" and "routes" specify information that is added on to the information returned from automatic configuration. The "ignore-auto-routes" and "ignore-auto-dns" properties modify this behavior. For methods that imply no upstream network, such as "shared" or "link-local", these properties must be empty.
    name
    string
    ipv6
| The setting's name, which uniquely identifies the setting within the connection. Each setting type has a name unique to that type, for example "ppp" or "wireless" or "wired".
    never-default
    boolean
    FALSE
| If TRUE, this connection will never be the default connection for this IP type, meaning it will never be assigned the default route by NetworkManager.
    route-data
    array of vardict
| Array of IPv6 routes. Each route dictionary contains at least 'dest' and 'prefix' entries, containing the destination IP address as a string, and the prefix length as a uint32. Most routes will also have a 'next-hop' entry, containing the next hop IP address as a string. If the route has a 'metric' entry (containing a uint32), that will be used as the metric for the route (otherwise NM will pick a default value appropriate to the device). Additional attributes may also exist on some routes.
    route-metric
    int64
    -1
| The default metric for routes that don't explicitly specify a metric. The default value -1 means that the metric is choosen automatically based on the device type. The metric applies to dynamic routes, manual (static) routes that don't have an explicit metric setting, address prefix routes, and the default route. Note that for IPv6, the kernel accepts zero (0) but coerces it to 1024 (user default). Hence, setting this property to zero effectively mean setting it to 1024. For IPv4, zero is a regular value for the metric.
    routes
    array of legacy IPv6 route struct (a(ayuayu))
    []
| Deprecated in favor of the 'route-data' property, but this can be used for backward-compatibility with older daemons. Note that if you send this property the daemon will ignore 'route-data'. Array of IPv6 route structures. Each IPv6 route structure is composed of an IPv6 address, a prefix length (1 - 128), an IPv6 next hop address (which may be zeroed out if there is no next hop), and a metric. If the metric is 0, NM will choose an appropriate default metric for the device.

Table 25. 802-11-wireless setting

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    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 Wi-Fi 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.
    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.
    channel
    uint32
    0
| Wireless channel to use for the Wi-Fi connection. The device will only join (or create for Ad-Hoc networks) a Wi-Fi network on the specified channel. Because channel numbers overlap between bands, this property also requires the "band" property to be set.
    cloned-mac-address
    byte array
| If specified, request that the Wi-Fi device use this MAC address instead of its permanent MAC address. This is known as MAC cloning or spoofing.
    hidden
    boolean
    FALSE
| If TRUE, indicates this network is a non-broadcasting network that hides its SSID. In this case various workarounds may take place, such as probe-scanning the SSID for more reliable network discovery. However, these workarounds expose inherent insecurities with hidden SSID networks, and thus hidden SSID networks should be used with caution.
    mac-address
    byte array
| If specified, this connection will only apply to the Wi-Fi device whose permanent MAC address matches. This property does not change the MAC address of the device (i.e. MAC spoofing).
    mac-address-blacklist
    array of string
    []
| A list of permanent MAC addresses of Wi-Fi devices to which this connection should never apply. Each MAC address should be given in the standard hex-digits-and-colons notation (eg "00:11:22:33:44:55").
    mode
    string
| Wi-Fi network mode; one of "infrastructure", "adhoc" or "ap". If blank, infrastructure is assumed.
    mtu
    uint32
    0
| If non-zero, only transmit packets of the specified size or smaller, breaking larger packets up into multiple Ethernet frames.
    name
    string
    802-11-wireless
| The setting's name, which uniquely identifies the setting within the connection. Each setting type has a name unique to that type, for example "ppp" or "wireless" or "wired".
    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.
    security
    None
| This property is deprecated, but can be set to the value '802-11-wireless-security' when a wireless security setting is also present in the connection dictionary, for compatibility with very old NetworkManager daemons.
    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 Wi-Fi network. NetworkManager internally tracks previously seen BSSIDs. The property is only meant for reading and reflects the BSSID list of NetworkManager. The changes you make to this property will not be preserved.
    ssid
    byte array
| SSID of the Wi-Fi network. Must be specified.
    tx-power
    uint32
    0
| If non-zero, directs the device to use the specified transmit power. Units are dBm. This property is highly driver dependent and not all devices support setting a static transmit power.

Table 26. 802-11-wireless-security setting

Key Name | Value Type | Default Value | Value Description
--- | --- | --- | ---
    auth-alg
    string
| When WEP is used (ie, key-mgmt = "none" or "ieee8021x") indicate the 802.11 authentication algorithm required by the AP here. 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.
    group
    array of string
    []
| A list of group/broadcast encryption algorithms which prevents connections to Wi-Fi networks that do not utilize one of the algorithms in the list. For maximum compatibility leave this property empty. Each list element may be one of "wep40", "wep104", "tkip", or "ccmp".
    key-mgmt
    string
| Key management used for the connection. One of "none" (WEP), "ieee8021x" (Dynamic WEP), "wpa-none" (Ad-Hoc WPA-PSK), "wpa-psk" (infrastructure WPA-PSK), or "wpa-eap" (WPA-Enterprise). This property must be set for any Wi-Fi connection that uses security.
    leap-password
    string
| The login password for legacy LEAP connections (ie, key-mgmt = "ieee8021x" and auth-alg = "leap").
    leap-password-flags
    NMSettingSecretFlags (uint32)
| Flags indicating how to handle the "leap-password" property.
    leap-username
    string
| The login username for legacy LEAP connections (ie, key-mgmt = "ieee8021x" and auth-alg = "leap").
    name
    string
    802-11-wireless-security
| The setting's name, which uniquely identifies the setting within the connection. Each setting type has a name unique to that type, for example "ppp" or "wireless" or "wired".
    pairwise
    array of string
    []
| A list of pairwise encryption algorithms which prevents connections to Wi-Fi networks that do not utilize one of the algorithms in the list. For maximum compatibility leave this property empty. Each list element may be one of "tkip" or "ccmp".
    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 Wi-Fi network.
    psk-flags
    NMSettingSecretFlags (uint32)
| Flags indicating how to handle the "psk" property.
    wep-key-flags
    NMSettingSecretFlags (uint32)
| Flags indicating how to handle the "wep-key0", "wep-key1", "wep-key2", and "wep-key3" properties.
    wep-key-type
    NMWepKeyType (uint32)
| Controls the interpretation of WEP keys. Allowed values are NM_WEP_KEY_TYPE_KEY (1), in which case the key is either a 10- or 26-character hexadecimal string, or a 5- or 13-character ASCII password; or NM_WEP_KEY_TYPE_PASSPHRASE (2), in which case the passphrase is provided as a string and will be hashed using the de-facto MD5 method to derive the actual WEP key.
    wep-key0
    string
| Index 0 WEP key. This is the WEP key used in most networks. See the "wep-key-type" property for a description of how this key is interpreted.
    wep-key1
    string
| Index 1 WEP key. This WEP index is not used by most networks. See the "wep-key-type" property for a description of how this key is interpreted.
    wep-key2
    string
| Index 2 WEP key. This WEP index is not used by most networks. See the "wep-key-type" property for a description of how this key is interpreted.
    wep-key3
    string
| Index 3 WEP key. This WEP index is not used by most networks. See the "wep-key-type" property for a description of how this key is interpreted.
    wep-tx-keyidx
    uint32
    0
| When static WEP is used (ie, key-mgmt = "none") and a non-default WEP key index is used by the AP, put that WEP key index here. Valid values are 0 (default key) through 3. Note that some consumer access points (like the Linksys WRT54G) number the keys 1 - 4.
