I'm not as adept at HP/UX before 10.20 (my first
experience with the OS),
but I understand 8.0 "fails over" to /etc/hosts if it has some issues with
DNS. Fine, but how can I get it to switch *back*? There's no
/etc/nsswitch.conf and I don't think this version supports it anyway.

Before HP-UX 10.10, you could only use nsswitch.conf to configure the
order of resolution for the hosts source. From 10.10 on, you can also
use nsswitch.conf to configure resolution order for the services,
networks, protocols, rpc, and netgroup sources. hosts: dns
[NOTFOUND=return] nis [NOTFOUND=return] files"
Appreciated, but from the same
resource,
"HP-UX 10.00 introduced Solaris's nsswitch.conf functionality"
so this won't apply to HP/UX 8.
