func IsLocalAddress

func IsLocalAddress(host string) (bool, error)

IsLocalAddress checks whether a given host/IP is local

func ParseHostAndBrickPath

func ParseHostAndBrickPath(brickPath string) (string, string, error)

ParseHostAndBrickPath parses the host & brick path out of req.Bricks list

func ValidateBrickPathLength

func ValidateBrickPathLength(brickPath string) error

ValidateBrickPathLength validates the length of the brick path

func ValidateBrickPathStats
