Overview

Cassandra is the database used for KFF 6.3 and newer.  During the KFF/Cassandra installation, you are prompted to enter the DNS name of your machine.  Cassandra then binds itself to that name as the RPC (Remote Procedure Call) address, only accepting connections directed toward that name.

For example, if the RPC address is set to "WinMachine", you will only be able to connect to the KFF if you direct communication to "WinMachine", even if the product accessing the KFF (FTK, etc) is also installed on "WinMachine".  Directing communication to "localhost" will fail.
