Functions

func ConnCloseRead

func ConnCloseRead(c net.Conn) error

ConnCloseRead calls c's CloseRead method. c is expected to be either a UnixConn or TCPConn as returned from this package.

func ConnCloseWrite

func ConnCloseWrite(c net.Conn) error

ConnCloseWrite calls c's CloseWrite method. c is expected to be either a UnixConn or TCPConn as returned from this package.

func Connect

func Connect(path string) (net.Conn, error)

Connect connects to tailscaled using a unix socket or named pipe.

func GOOSUsesPeerCreds

func GOOSUsesPeerCreds(goos string) bool

GOOSUsesPeerCreds is like PlatformUsesPeerCreds but takes a runtime.GOOS value instead of using the current one.

func Listen

func Listen(path string) (net.Listener, error)

Listen returns a listener either on Unix socket path (on Unix), or the NamedPipe path (on Windows).

func LocalTCPPortAndToken

func LocalTCPPortAndToken() (port int, token string, err error)

LocalTCPPortAndToken returns the port number and auth token to connect to the local Tailscale daemon. It's currently only applicable on macOS when tailscaled is being run in the Mac Sandbox from the App Store version of Tailscale.

func PlatformUsesPeerCreds

func PlatformUsesPeerCreds() bool

PlatformUsesPeerCreds reports whether the current platform uses peer credentials to authenticate connections.
