ie: named is a server which looks up hostnames and nscd is a cacheing
daemon which remembers reciently used hostnames->ip_addresses (I would
think similarly to /etc/host where you could put frequently used
addresses).

But, and that's why I pointed to the configuration file, it's used only
for the passwd, group, and hosts files, nothing more. It does not caches
internet names, unless listed in the hosts file.

The name of the nscd is missleading. In fact, the man page says as much in
the second paragraph:

Nscd provides cacheing for accesses of the passwd(5), group(5), and
hosts(5) databases through standard libc interfaces, such as
getpwnam(3), getpwuid(3), getgrnam(3), getgrgid(3),
gethostbyname(3), and others.

man pages are, lets say, mandatory reading, but not easy reading, IMO.
They are more like a quick way to remember what one already knows but
needs refreshing.


Thus, for a real internet name cache thing, we need named from bind. As it
comes in the rpm, without doing anything, it already works in that manner.
We only need to edit /etc/named.conf, find the "forwarders" line, and put
there our ISP DNSs.
