Constants ¶
const DHCPv6ClientPort = 546
const DHCPv6ServerPort = 547
const MinPackSizeDHCPv6 = 10*4 + 2*4 + 2*4 // minimal DHCPv6 header size
This is the aprox. minimal size of a DHCP packet
const MinPackSizeMLDv6 = 48

Functions ¶
func CheckIANA ¶
func CheckIANA(iana IANontemporaryAddress, clientInfo ClientInfoV6) bool
checkIANAs returns true if all addresses of the given IANA option are also in the clientInfo
func EncodeOptions ¶
func EncodeOptions(iaid IAID, info ClientInfoV6) ([]byte, error)
EncodeOptions encodes the IP
Types ¶
type ClientInfoV6 ¶
type ClientInfoV6 struct {
Temporary bool
IPAddrs []net.IP
//NextServer net.IP
//BootFileName string
Timeouts struct {
ValidLifetime time.Duration
PreferredLifetime time.Duration
T1RenewalTime time.Duration
T2RebindingTime time.Duration
}
Options struct {
HostName string
DomainName string
DomainNameServers []net.IP
NTPServers []net.IP
}
}
type DHCPV6Conn ¶
type DHCPV6Conn struct {
// contains filtered or unexported fields
}
func ListenDHCPv6 ¶
ListenDHCPv6 creates a connection that listens on the given interface for dhcpv6 traffic destined to the given address daddr, and sends replies from the given address laddr.
daddr may be a multicast address (or any other valid IPv6 address). If daddr is ::0, then we'll listen to all DHCPv6 message on the interface.
laddr must not be a multicast address, but may be any other valid IPv6 address (e.g. unicast or link-local address).
func (*DHCPV6Conn) Close ¶
func (c *DHCPV6Conn) Close() error
func (*DHCPV6Conn) ReadFrom ¶
func (c *DHCPV6Conn) ReadFrom() (layers.DHCPv6, net.IP, net.HardwareAddr, error)
ReadFrom returns the parsed packet, source IP, source MAC, error
func (*DHCPV6Conn) WriteTo ¶
func (c *DHCPV6Conn) WriteTo(pack layers.DHCPv6, dstIP net.IP, dstMAC net.HardwareAddr) error
type IANontemporaryAddress ¶
type IANontemporaryAddress struct {
IAID IAID
T1 uint32
T2 uint32
AddressOptions iaAddresses
StatusCodeOption statusCodeOption
OtherOptions iaOptions
}
func ParseIANAOption ¶
func ParseIANAOption(ianaOpt layers.DHCPv6Option) IANontemporaryAddress
parseIANAOptions parses an IA Non-Temporary Address DHCPv6 Option
type MLDv2Filter ¶
type MLDv2Filter uint8
const ( MLDv2Include MLDv2Filter = 0 MLDv2Exclude MLDv2Filter = 1 )
func (MLDv2Filter) String ¶
func (m MLDv2Filter) String() string
type MulticastV6Conn ¶
type MulticastV6Conn struct {
// contains filtered or unexported fields
}
func (*MulticastV6Conn) JoinMulticast ¶
func (c *MulticastV6Conn) JoinMulticast(multicastAddr net.IP)
join a multicast group
func (*MulticastV6Conn) LeaveMulticast ¶
func (c *MulticastV6Conn) LeaveMulticast(multicastAddr net.IP)
leave a multicast group
