Golang AuthExternal Examples

Example #1

File: dbus.go Project: 98pm/docker

func (c *Conn) initConnection() error {
	var err error
	c.conn, err = dbus.SystemBusPrivate()
	if err != nil {
		return err
	}

	// Only use EXTERNAL method, and hardcode the uid (not username)
	// to avoid a username lookup (which requires a dynamically linked
	// libc)
	methods := []dbus.Auth{dbus.AuthExternal(strconv.Itoa(os.Getuid()))}

	err = c.conn.Auth(methods)
	if err != nil {
