Functions

func NoopFilter

func NoopFilter(*SockTabEntry) bool

NoopFilter - a test function returning true for all elements

Types

type AcceptFn

type AcceptFn func(*SockTabEntry) bool

AcceptFn is used to filter socket entries. The value returned indicates whether the element is to be appended to the socket list.

type Process

type Process struct {
	// contains filtered or unexported fields
}

Process holds the PID and process name to which each socket belongs

func (*Process) String

func (p *Process) String() string

type SkState

type SkState uint8

SkState type represents socket connection state

func (SkState) String

func (s SkState) String() string

type SockAddr

type SockAddr struct {
	IP   net.IP
	Port uint16
}

SockAddr represents an ip:port pair

func (*SockAddr) KnownPort

func (s *SockAddr) KnownPort() string

func (*SockAddr) String

func (s *SockAddr) String() string

type SockTabEntry

type SockTabEntry struct {
	LocalAddr  *SockAddr
	RemoteAddr *SockAddr
	State      SkState
	UID        uint32
	Process    *Process
	// contains filtered or unexported fields
}

SockTabEntry type represents each line of the /proc/net/[tcp|udp]

func TCP6Socks

func TCP6Socks(accept AcceptFn) ([]SockTabEntry, error)

TCP6Socks returns a slice of active TCP IPv4 sockets containing only those elements that satisfy the accept function

func TCPSocks

func TCPSocks(accept AcceptFn) ([]SockTabEntry, error)

TCPSocks returns a slice of active TCP sockets containing only those elements that satisfy the accept function

func UDP6Socks

func UDP6Socks(accept AcceptFn) ([]SockTabEntry, error)

UDP6Socks returns a slice of active UDP IPv6 sockets containing only those elements that satisfy the accept function

func UDPSocks

func UDPSocks(accept AcceptFn) ([]SockTabEntry, error)

UDPSocks returns a slice of active UDP sockets containing only those elements that satisfy the accept function
