:^), 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
