Many thanks for continuing to improve my understanding on this!

Here's the items ending in 'd' from 'ps -ax' (others removed):
==============
PID TTY STAT TIME COMMAND
2 ? SW 0:00 [keventd]
3 ? SWN 0:00 [ksoftirqd_CPU0]
4 ? SW 0:00 [kswapd]
5 ? SW 0:00 [kreclaimd]
6 ? SW 0:00 [bdflush]
7 ? SW 0:00 [kupdated]
51 ? SW 0:00 [khubd]
76 ? S 0:00 /usr/sbin/syslogd
79 ? S 0:00 /usr/sbin/klogd -c 3
81 ? S 0:00 /usr/sbin/inetd
84 ? S 0:02 /usr/sbin/sshd
89 ? S 0:00 /usr/sbin/lpd
91 ? S 0:00 /usr/sbin/crond -l10
95 ? S 0:00 /usr/sbin/atd -b 15 -l 1
==============
With the exception of 'lpd', I'm not at all sure I know what the
others are about.

Lines without # in inetd.conf are:
==============
time stream tcp nowait root internal
time dgram udp wait root internal
ftp stream tcp nowait root /usr/sbin/tcpd proftpd
telnet stream tcp nowait root /usr/sbin/tcpd in.telnetd
comsat dgram udp wait root /usr/sbin/tcpd in.comsat
shell stream tcp nowait root /usr/sbin/tcpd in.rshd -L
login stream tcp nowait root /usr/sbin/tcpd in.rlogind
ntalk dgram udp wait root /usr/sbin/tcpd in.talkd
finger stream tcp nowait nobody /usr/sbin/tcpd in.fingerd -u
auth stream tcp wait nobody /usr/sbin/in.identd in.identd -P/dev/null
netbios-ssn stream tcp nowait root /usr/sbin/smbd smbd
netbios-ns dgram udp wait root /usr/sbin/nmbd nmbd
# End of inetd.conf.
==============
So - should I be changing (removing, deleting...) anything, based on
what you can see here? Also, where could I read more (generally) about
what all these items are?
As always, thanks for your input.
Gerald.
