Is there a Ping Module? I'm creating a support site for a hosting company in D7 and one of the features that they have asked for is for drupal to ping each of the servers, (I have a content type called Server which has ipaddresses attached to it) and report back the status.  I want to set it up as cron job.  Is there a module for Drupal that I can add that gives me this feature?  if not can you give me any pointers how to get started on building one?

Thanks

The multiping module will provide this feature in Drupal 7, since the ping module is not part of core anymore. The D7 branch hasn't been started, but there is a patch that you can test that ports the module to Drupal 7. If you test it and it works for you, please comment on that issue, the more people that review that patch the closer the module will get to a full D7 release.
