var ( BroadcastMAC = net.HardwareAddr{0xff, 0xff, 0xff, 0xff, 0xff, 0xff} LoopbackMAC = net.HardwareAddr{0x00, 0x00, 0x00, 0x00, 0x00, 0x00} )
Functions ¶
func AddrEqual ¶ added in v0.0.14
AddrEqual compares two address strings and returns true if they are equal.
It treats loopback and unspecified IPs as equivalent. Returns false in case of inequality or error.
func DisplayInterfaces ¶
func GetDefaultGatewayIPv4 ¶
func GetDefaultInterface ¶
func InterfaceByName ¶
InterfaceByName returns the interface specified by name.
func IsLocalAddress ¶ added in v0.0.10
func ListenPacket ¶ added in v0.0.14
func ListenPacket(conf *ListenConfig) (*packet.Conn, error)
Types ¶
type ListenConfig ¶ added in v0.0.14
type ListenConfig struct {
Device *net.Interface // network interface which to bind to, if not specified default interface is used
Protocol int // network protocol, defaults to ETH_P_ALL
Promiscuous *bool // enable or disable promiscuous mode
FilterExpr string // packet filter expression like in tcpdump
}
