RingFinger is used by RingServer clients to discover the RingServer’s TupleSpace. Typically, all a client needs to do is call RingFinger.primary to retrieve the remote TupleSpace, which it can then begin using.

To find the first available remote TupleSpace:


To create a RingFinger that broadcasts to a custom list:

rf = Rinda::RingFinger.new  ['localhost', '']

Rinda::RingFinger also understands multicast addresses and sets them up properly. This allows you to run multiple RingServers on the same host:

rf = Rinda::RingFinger.new ['']

You can set the hop count (or TTL) for multicast searches using #multicast_hops.

If you use IPv6 multicast you may need to set both an address and the outbound interface index:

rf = Rinda::RingFinger.new ['ff02::1']
rf.multicast_interface = 1

At this time there is no easy way to get an interface index by name.
