Very good suggestion. In fact, my resolv.conf DID have an entry for my
system, but it was in reverse order. I.e., to use your example, it was:
I don't understand why the resolver didn't fall through to the second
nameserver, but it evidently did not. After I put the nameservers in the
order you suggest, everything seems to be working fine!

Another good suggestion. I had forgotten about the immutable attribute. I've
set it now. (It's a safe bet that in six months or so I'll be sending a note
to the list, whining about how I can't edit resolv.conf ;-)
Thanks for your help.
