Match settings

§Properties

§driver

A list of driver names to match. Each element is a shell wildcard pattern.

See NMSettingMatch:interface-name for how special characters ‘|’, ‘&’, ‘!’ and ‘\’ are used for optional and mandatory matches and inverting the pattern.

Readable | Writeable

§interface-name

A list of interface names to match. Each element is a shell wildcard pattern.

An element can be prefixed with a pipe symbol (|) or an ampersand (&). The former means that the element is optional and the latter means that it is mandatory. If there are any optional elements, than the match evaluates to true if at least one of the optional element matches (logical OR). If there are any mandatory elements, then they all must match (logical AND). By default, an element is optional. This means that an element “foo” behaves the same as “|foo”. An element can also be inverted with exclamation mark (!) between the pipe symbol (or the ampersand) and before the pattern. Note that “!foo” is a shortcut for the mandatory match “&!foo”. Finally, a backslash can be used at the beginning of the element (after the optional special characters) to escape the start of the pattern. For example, “&\!a” is an mandatory match for literally “!a”.

Readable | Writeable

§kernel-command-line

A list of kernel command line arguments to match. This may be used to check whether a specific kernel command line option is set (or unset, if prefixed with the exclamation mark). The argument must either be a single word, or an assignment (i.e. two words, joined by “=”). In the former case the kernel command line is searched for the word appearing as is, or as left hand side of an assignment. In the latter case, the exact assignment is looked for with right and left hand side matching. Wildcard patterns are not supported.

See NMSettingMatch:interface-name for how special characters ‘|’, ‘&’, ‘!’ and ‘\’ are used for optional and mandatory matches and inverting the match.

Readable | Writeable

§path

A list of paths to match against the ID_PATH udev property of devices. ID_PATH represents the topological persistent path of a device. It typically contains a subsystem string (pci, usb, platform, etc.) and a subsystem-specific identifier.

For PCI devices the path has the form “pci-$domain:$bus:$device.$function”, where each variable is an hexadecimal value; for example “pci-0000:0a:00.0”.

The path of a device can be obtained with “udevadm info /sys/class/net/$dev | grep ID_PATH=” or by looking at the “path” property exported by NetworkManager (“nmcli -f general.path device show $dev”).

Each element of the list is a shell wildcard pattern.

See NMSettingMatch:interface-name for how special characters ‘|’, ‘&’, ‘!’ and ‘\’ are used for optional and mandatory matches and inverting the pattern.

Readable | Writeable

Setting

§name

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 “802-11-wireless” or “802-3-ethernet”.

Readable

§Implements

SettingExt

GLib type: GObject with reference counted clone semantics.

Implementations§

Source§

impl SettingMatch

Source

Source

pub fn interface_name(&self, idx: i32) -> GString

Since 1.46, access at index “len” is allowed and returns NULL.

index number of the DNS search domain to return

§Returns

the interface name at index @idx

Source

pub fn interface_names(&self) -> Vec<GString>

§interface_name

the interface name to remove

§Returns

true if the interface name was found and removed; false if it was not.

Source

pub fn set_interface_name(&self, interface_name: &[&str])

A list of interface names to match. Each element is a shell wildcard pattern.

An element can be prefixed with a pipe symbol (|) or an ampersand (&). The former means that the element is optional and the latter means that it is mandatory. If there are any optional elements, than the match evaluates to true if at least one of the optional element matches (logical OR). If there are any mandatory elements, then they all must match (logical AND). By default, an element is optional. This means that an element “foo” behaves the same as “|foo”. An element can also be inverted with exclamation mark (!) between the pipe symbol (or the ampersand) and before the pattern. Note that “!foo” is a shortcut for the mandatory match “&!foo”. Finally, a backslash can be used at the beginning of the element (after the optional special characters) to escape the start of the pattern. For example, “&\!a” is an mandatory match for literally “!a”.
