Mostly OK? Besides the short timeouts, which are for testing and will be 
increased to reasonable values once the whole system functions 
correctly, and the combined internal/external name servers (which I 
fixed)  what's wrong?

No entries at all in named.log now that it's started not making dynamic 
updates at all. The named.log shows startup messages, and nothing else.

As to the name server, it would be pluto actually, not jupiter. Here's

I don't know what's up, but there's no update of DNS at all right now. 
I'm stumped. As far as I can tell, all is fine in the config. Maybe
