## ping

    $p->ping(host[, timeout])

Pings remote host and waits for a response. Takes the following arguments:

host

  Specified as either the hostname or the IP number of the remote host.

timeout

  Optional, must be greater than 0 seconds if specified. Defaults to whatever was specified when the ping object was created.

If host cannot be found or there is a problem with the IP number, returns `undef`. Otherwise, returns `1` if the host is reachable and `0` if it is not.
