Types ¶

type Addr ¶

type Addr netlink.Addr

An Addr represents an IP address and its associated routing prefix.

func ParseCIDR ¶

func ParseCIDR(s string) (*Addr, error)

ParseCIDR parses s as a CIDR notation IP address and prefix length.

func (*Addr) Network ¶

func (addr *Addr) Network() string

Network returns the network name, "ip+net".

func (*Addr) String ¶

func (addr *Addr) String() string

String returns the CIDR notation of the address.

type Device ¶

type Device struct {
	Index int
	Type  int
	io.ReadWriteCloser
}

Device represents a TUN/TAP device.

func New ¶

func New(devType int) (*Device, error)

New creates a new TUN/TAP device.

func NewTAP ¶

func NewTAP() (*Device, error)

NewTAP creates a new TAP device.

func NewTUN ¶

func NewTUN() (*Device, error)

NewTUN creates a new TUN device.

func (*Device) AddAddr ¶

func (dev *Device) AddAddr(addr *Addr) error

AddAddr adds the specified IP address to the interface.

func (*Device) Addrs ¶

func (dev *Device) Addrs() ([]*Addr, error)

Addrs returns all IPv4 and IPv6 addresses assigned to the interface.

func (*Device) Attrs ¶

func (dev *Device) Attrs() *netlink.LinkAttrs

Attrs returns the link attributes.

func (*Device) DelAddr ¶

func (dev *Device) DelAddr(addr *Addr) error

DelAddr removes the specified IP address from the interface.

func (*Device) Down ¶

func (dev *Device) Down() error

Down changes the state of the interface to DOWN.

func (*Device) SetMTU ¶

func (dev *Device) SetMTU(mtu int) error

SetMTU sets the maximum transmission unit of the device.

func (*Device) Up ¶
