Types ¶
type Handler4 ¶
type Handler4 struct {
// contains filtered or unexported fields
}
Handler4 maintains the underlying socket connection
func (*Handler4) ProcessPacket ¶
ProcessPacket parses an ICMP4 packet and log the frame.
This is a simple processor to common ICMP4 packets includin echo request/reply, destination unreacheable and redirect. It does not contain any logic beyond logging.
type Handler6 ¶
type Handler6 struct {
Router *Router
LANRouters map[netip.Addr]*Router
sync.Mutex
// contains filtered or unexported fields
}
Handler implements ICMPv6 Neighbor Discovery Protocol see: https://mdlayher.com/blog/network-protocol-breakdown-ndp-and-go/
func (*Handler6) Close ¶
Close releases underlying resources. The handler is not longer usable after calling Close().
func (*Handler6) PingAll ¶
PingAll sends an echo request to the IPv6 multicast address to encourage hosts to reply.
func (*Handler6) PrintTable ¶
func (h *Handler6) PrintTable()
PrintTable logs ICMP6 tables to standard out
func (*Handler6) ProcessPacket ¶
ProcessPacket handles icmp6 packets and executes neighbor advertising spoofing for target LLAs.
func (*Handler6) StartHunt ¶
StartHunt will actively poison the target IP with fake icmp6 NA to redirect all traffic to us. Poisoning will continue until StopHunt() is called.
The target IP must be a IPv6 LLA or nil. If IP is nil, we use unicast ethernet address but the multicast ip address to get the packet to the target host.
func (*Handler6) StartRADVS ¶
func (h *Handler6) StartRADVS(managed bool, other bool, prefixes []packet.PrefixInformation, rdnss *packet.RecursiveDNSServer) (*RADVS, error)
type Router ¶
type Router struct {
Addr packet.Addr
ManagedFlag bool // if true, hosts should get IP from DHCP, if false, use SLAAC IP
OtherCondigFlag bool // if true, hosts should get other info from DHCP
Preference byte
MTU uint32
ReacheableTime int // Must be no greater than 3,600,000 milliseconds (1hour)
RetransTimer int //
CurHopLimit uint8
DefaultLifetime time.Duration // A value of zero means the router is not to be used as a default router
Prefixes []packet.PrefixInformation
RDNSS *packet.RecursiveDNSServer // Pointer to facilitate comparison
Options packet.NewOptions
// contains filtered or unexported fields
}
Router holds a router identification and is useful to implement Router Advertisement Servers.
