OK, here goes:
"nscd" is the glibc nameservice caching daemon, used almost entirely in
NIS-based networks to ease network performance problems on account of
the nameservice overhead. Unless you're running a very
performance-sapping network nameservice such as NIS, NIS+, or LDAP, you
should turn this _off_.
Even if you elect to leave it turned on, you should disable its caching
of DNS information, because it has a habit of caching DNS data past its
time-to-live expiration.
"portmap" is the Sun Microsystems RPC portmapper, a network service used
primarily as a transport for NIS and NFS on the server end (only). If
your machine isn't functioning as an NFS or NIS server, then turn it
off.
"syslogd" and "klogd" are important system logging daemons. Leave them
on.
"mingetty" (minimum-sized get TTY service) is what provides you with
your six virtual consoles, the ones you can switch among using
Ctrl-Alt-F1, Ctrl-Alt-F2, etc. You probably don't need six, and can
save some RAM by commenting out four of the lines in /etc/inittab, the
ones that look like this:
1:2345:respawn:/sbin/getty 38400 tty1
2:23:respawn:/sbin/getty 38400 tty2
3:23:respawn:/sbin/getty 38400 tty3
4:23:respawn:/sbin/getty 38400 tty4
5:23:respawn:/sbin/getty 38400 tty5
6:23:respawn:/sbin/getty 38400 tty6
Put a "#" character in front of the lines starting with 3 through 6.
Next time you enter your default runlevel, you'll have only two copies
of mingetty running.
All those processes at the end of the list starting with "k" are KDE
pieces. If I were you, I simply wouldn't run those or any X11 stuff on
a server at all. Change your configuration (using YaST2 or whatever) to
just not start up XFree86. That will save a whole lot of RAM.
