I checked about most of the daemons, but I still don't understand why I
have several "nscd" running. Man tells me it's the name server cache
daemon... why should it have 6 or 7 processes?
nscd is indeed the name service cache daemon. It not only caches
(if so configured) DNS lookups, but also authentication requests
(such as LDAP queries if you do authentication that way instead
of the usual /etc/passwd etc.). In /etc/nscd.conf you can configure
the number of processes to use (threads directive), which of course
can be tuned to suit your needs. Have a look at that configuration
file, it's enlightening :-)
As my recent experience with slapd and nscd on Debian stable showed
me, don't use nscd unless it's really needed to cut down the load
on the system. [we had *serious* trouble with the communication
between slapd and nscd breaking down, load going up, any services
needing authentication going down, and finally a system unresponsive
except for replying to pings].
In your case (for your desktop), stop it, you don't need it.
Greetings, Eric
