===Ping===

A ping is a message that is sent out at regular intervals - normally to a broadcast address((But can also go to a single IP))

They are generally used as a "keep alive" signal to establish that a particular network device is still connected.

See ''[[commands:network_commands:new_pingtarget]]'' for how to set a ping up

The command given for a given ping will pass through the system that interpolates variable [[concepts:variables:references]].
