RingyDingy

RingyDingy is a little boat that keeps your DRb service afloat! RingyDingy automatically registers a service with a RingServer. If communication between the RingServer and the RingyDingy is lost, RingyDingy will re-register its service with the RingServer when it reappears. Similarly, the RingServer will automatically drop registrations by a RingyDingy that it can't communicate with after a short timeout. RingyDingy also includes a RingServer wrapper that adds verbose mode to see what services as they register and expire and an option to list all available services on the network.
