I got NIS working except one Radius server won’t bind to them and I can’t login remotely to fix it as it is a physical machine and not a virtual.  I would like to fix this but so far have not been able to get the modern Radius to work.  Documentation says it will read the old style configuration files but I’ve not been able to get it to function.  The examples they give are unfortunately much simpler than the insanely messy setup we have here which is mostly the result of dealing with a large number of dial-up and DSL providers in the past (now only a handful remain).
