You can use Ping from the Ruby standard library.

require 'ping'
Ping.pingecho "google.com", <timeout>, <port>

Where timeout is the number of seconds to wait for a reply (defaults to 
5) and port is the port to use (defaults to the 'echo' port)


Unless you have something more specific you are trying to do this ought 
to work.
