linux manual

Actions

name description
list List address labels.
add Add an address label.
delete Delete an address label
flush Flush all address labels in the kernel

List

List the current address label entries in the kernel.

Result

Returns an array of IPAddressLabel structs.

IPAddressLabel Fields

Field Type Description
address string (IPv4 or IPv6) address attached to a network device.
prefixlen integer The number of bits in the netmask
label integer The label for the prefix.

Example

host.ip('addrlabel', 'list').to_a
[
  [0] #<Struct:Kanrisuru::Core::IP::IPAddressLabel:0x000006e0
    address = "::1",
    label = 0,
    prefix_length = 128
  >,
  [1] #<Struct:Kanrisuru::Core::IP::IPAddressLabel:0x00000730
    address = "::",
    label = 3,
    prefix_length = 96
  >,
  [2] #<Struct:Kanrisuru::Core::IP::IPAddressLabel:0x00000780
    address = "::ffff:0.0.0.0",
    label = 4,
    prefix_length = 96
  >,
  [3] .. [6],
  [7] #<Struct:Kanrisuru::Core::IP::IPAddressLabel:0x00000910
    address = "fec0::",
    label = 11,
    prefix_length = 10
  >,
  [8] #<Struct:Kanrisuru::Core::IP::IPAddressLabel:0x00000960
    address = "fc00::",
    label = 5,
    prefix_length = 7
  >,
  [9] #<Struct:Kanrisuru::Core::IP::IPAddressLabel:0x000009b0
    address = "::",
    label = 1,
    prefix_length = 0
  >
]

Add

Add an address label entry to the kernel.

This command needs escalated privileges to make changes to certain files and directory ownership.

Parameters

Field Type Description
prefix string
 		The IP prefix identifies the number of significant bits used to identify a network.
dev string
 		The outbound interface.
label integer
 		Numeric label for the prefix.

Result

No explicit data struct returned, only option is success?, failure?, and status to see if the program exited properly.

Example

host.su('root')
result = host.ip('addrlabel', 'add', dev: 'ens3', prefix: '2001:6f8:12d8:2::/64', label: 200)
result.success?
true

Delete

Delete an address label entry from the kernel.

This command needs escalated privileges to make changes to certain files and directory ownership.

Parameters

Coincide with the arguments of add but the label is not required.

Result

No explicit data struct returned, only option is success?, failure?, and status to see if the program exited properly.

Example

host.su('root')
result = host.ip('addrlabel', 'del', dev: 'ens3', prefix: '2001:6f8:12d8:2::/64')
result.success?
true

Flush

Flush all address labels in the kernel. This does not restore any default settings.

Result

No explicit data struct returned, only option is success?, failure?, and status to see if the program exited properly.

Example

host.su('root')
result = host.ip('addrlabel', 'flush')
result.success?
true
