Functions ¶

func GetBroadcastAddress ¶ added in v0.8.13

func GetBroadcastAddress(ip net.IP, netMask net.IPMask) net.IP

GetBroadcastAddress returns the broadcast address of the given IP and network mask. If a mixed IPv4/IPv6 input is given, it returns nil.

func IPPortFromAddr ¶ added in v1.4.6

func IPPortFromAddr(addr net.Addr) (ip net.IP, port uint16, err error)

IPPortFromAddr extracts or parses the IP address and port contained in the given address.

func IPsToRRs ¶ added in v0.4.12

func IPsToRRs(domain string, ips []net.IP) ([]dns.RR, error)

IPsToRRs transforms the given IPs to resource records.

func IsValidFqdn ¶

func IsValidFqdn(fqdn string) bool

IsValidFqdn returns whether the given string is a valid fqdn.

func ParseIPPort ¶ added in v1.4.6

func ParseIPPort(address string) (net.IP, uint16, error)

ParseIPPort parses a <ip>:port formatted address.

func ProtocolFromNetwork ¶ added in v1.4.6

func ProtocolFromNetwork(net string) (protocol packet.IPProtocol)

ProtocolFromNetwork returns the protocol from the given net, as used in the "net" golang stdlib.

Types ¶

type IPScope ¶ added in v0.6.7

type IPScope int8

IPScope is the scope of the IP address.

const (
	Invalid IPScope = iota - 1
	Undefined
	HostLocal
	LinkLocal
	SiteLocal
	Global
	LocalMulticast
	GlobalMulticast
)

Defined IP Scopes.

func ClassifyIP ¶

func ClassifyIP(ip net.IP) IPScope

ClassifyIP returns the network scope of the given IP address. Deprecated: Please use the new GetIPScope instead.

func GetIPScope ¶ added in v0.6.7

func GetIPScope(ip net.IP) IPScope

GetIPScope returns the network scope of the given IP address.

func (IPScope) IsGlobal ¶ added in v0.6.7

func (scope IPScope) IsGlobal() bool

IsGlobal returns true if the scope is global.

func (IPScope) IsLAN ¶ added in v0.6.7

func (scope IPScope) IsLAN() bool

IsLAN returns true if the scope is site-local or link-local.

func (IPScope) IsLocalhost ¶ added in v0.6.7

func (scope IPScope) IsLocalhost() bool

IsLocalhost returns whether the IP refers to the host itself.

type SimpleStreamAssembler ¶

type SimpleStreamAssembler struct {
	Cumulated    []byte
	CumulatedLen int
	Complete     bool
}

SimpleStreamAssembler is a simple assembler for github.com/google/gopacket/tcpassembly.

func NewSimpleStreamAssembler ¶

func NewSimpleStreamAssembler() *SimpleStreamAssembler

NewSimpleStreamAssembler returns a new SimpleStreamAssembler.

func (*SimpleStreamAssembler) Reassembled ¶

func (a *SimpleStreamAssembler) Reassembled(reassembly []tcpassembly.Reassembly)

Reassembled implements tcpassembly.Stream's Reassembled function.

func (*SimpleStreamAssembler) ReassemblyComplete ¶

func (a *SimpleStreamAssembler) ReassemblyComplete()

ReassemblyComplete implements tcpassembly.Stream's ReassemblyComplete function.

type SimpleStreamAssemblerManager ¶

type SimpleStreamAssemblerManager struct {
	InitLock sync.Mutex
	// contains filtered or unexported fields
}

SimpleStreamAssemblerManager is a simple manager for github.com/google/gopacket/tcpassembly.

func (*SimpleStreamAssemblerManager) GetLastAssembler ¶

func (m *SimpleStreamAssemblerManager) GetLastAssembler() *SimpleStreamAssembler

GetLastAssembler returns the newest created stream assembler.

func (*SimpleStreamAssemblerManager) New ¶

func (m *SimpleStreamAssemblerManager) New(net, transport gopacket.Flow) tcpassembly.Stream

New returns a new stream assembler.
