Functions

func DeviceType

func DeviceType(openPorts []int) string

DeviceType attempts to classify the device type based on open ports.

Types

type OSGuess

type OSGuess struct {
	OS         string
	Confidence int // 0-100
	TTL        int
	Method     string
}

OSGuess represents an OS detection result.

func DetectByTTL

func DetectByTTL(host string, timeout time.Duration) (*OSGuess, error)

DetectByTTL performs basic OS detection by analyzing the initial TTL value. This is a passive/lightweight approach based on the ICMP or TCP response TTL.
