Functions ¶

func GetMaxFD ¶

func GetMaxFD() (int, error)

GetMaxFD returns the maximum number of open file descriptors.

func SuggestTimeout ¶

func SuggestTimeout(n int) time.Duration

SuggestTimeout suggests a global timeout based on the number of ports

Types ¶

type Port ¶

type Port struct {
	Port  int
	State State
}

type Result ¶

type Result []Port

func ConnectScan ¶

func ConnectScan(address string, ports []int, timeout time.Duration) (Result, []error)

ConnectScan uses the basic connect() method to determine if ports are open. address can be a hostname, not limited to IP address. ConnectScan retries the FILTERED ports for once again.

func StealthScan ¶

func StealthScan(ip string, ports []int, global, read time.Duration) (Result, []error)

ip must be a valid IPv4/IPv6 address, not a domain. StealthScan retries the FILTERED ports for once again. StealthScan has two timeout: One is the global timeout, which is set to stop reading packets after X time. Second is the read timeout, which is set to terminate reading from socket after X time, if no packe read. Read timeout is useful if (for example) the global timeout is 10 sec, but no packet arrive after 2 sec, so you dont have to wait for the remaining 8 sec.

func (*Result) GetPorts ¶

func (r *Result) GetPorts(s State) []Port

func (*Result) GetPortsInt ¶

func (r *Result) GetPortsInt(s State) []int

GetPorts returns the ports from r with state s.

func (*Result) Len ¶

func (r *Result) Len(s State) int

type State ¶

type State uint8

const (
	OPEN State = iota
	CLOSED
	FILTERED
)

func (State) String ¶

func (s State) String() string
