Functions

func Ping

func Ping(network, address string, timeout time.Duration) error

Ping connects to the address on the named network, using net.DialTimeout, and immediately closes it. It returns the connection error. A nil value means success. For examples of valid values of network and address, see the documentation of net.Dial

func PingN

func PingN(network, address string, timeout time.Duration, count int, c chan<- error)

PingN calls Ping the specified number of times, and sends the results to the given channel.
