:^), I'm not Carlos, but:

named

is a Domain Name System (DNS) server, part of the BIND 9
distribution from ISC. For more information on the DNS, see RFCs
1033, 1034, and 1035.

NAME
/usr/sbin/nscd - name service cache daemon
DESCRIPTION
Nscd is a daemon that provides a cache for the most common name
service requests. The default configuration file, /etc/nscd.conf,
determines the behavior of the cache daemon. See nscd.conf(5).

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).

:^) at least as I read ....

Thanks, Patrick!

Sometimes it takes just a 'nudge' to get over these humps. I was overlooking
the proactive query component of the DNS "server" which is, at least
contextually a 'client' of sorts.

regards,

Carl
