Ah. Well our darn Cisco 1601 power supply went poof  :(. That's lame too
Would that be a FAQ? Or most people have working Net connections :).

I'd rather they just leave the trailing '.' in, but that's me wanting to
see everything, warts and all, but I guess certain apps may not like it.

Thanks! How'd I miss that option.. Doh :).
Whilst there I also saw allow-query in a new light...
Now gonna restrict allow-query (only let outsiders ask about my public
domains, and not others). Wonder if I'll need to restrict allow-recursion
then. Nev mind restrict first, just in case I screw up somewhere..
Woohoo, now I can set things up in my fav ultraparanoid outsider unfriendly

Still, they've been popping up a bit more often than I'd like. <sigh>.
Would what I'm doing help reduce the chances of cache poisoning? I'm
thinking that by restricting queries, the attacker cannot easily query my
server and make it get info from elsewhere. Only way then is if it stumbles
onto poison because of internal user queries.
Thanks very much again,
 The power LED goes on for a while, then goes off, and then I hear a
very high pitched whine which slowly drops in frequency and then off when I
cut the mains. After that, the power LED stays off, even when I turn the
mains back on. Grrr.
