Default network pinger command uses -t argument for timeout

The network pinger uses a network timeout as an argument for -t in the ping command.

The man page for ping says -t sets TTL, which is "The TTL value of an IP packet represents the maximum number of IP routers that the packet can go through before being thrown away. In current practice you can expect each router in the Internet to decrement the TTL field by exactly one."

It looks like the intent was to use -W timeout, Time to wait for a response, in seconds.
