I have a master NIS server (us.domain.net).
On it, everything looks and works just peachy: `ypwhich -m` returns the
master NIS server's name, I can do `ypcat -k hosts` etcetera.
In short, everything works the way it's supposed to.
Except for one small problem. Any other server I set up whether as a slave
or a client, can't talk to the NIS master.
Network connectivity is fine, I can ping the IP, traceroute, telnet... you
`rpcinfo nismaster` on any of the would-be clients/slave servers returns
back a ton of RPC services listening, including "ypbind" and the rest of the
gang. Except that their own ypbind can't bind to any of them.
