Unneeded services for server edition

[howard chen]

Hello,

I have installed UBuntu 9.04 (Jaunty) server edition, by default, it
auto started with the following services:

apparmor
atd
bootlogs.sh
console-setup
cron
dbus
keyboard-setup
klogd
linux-restricted-modules-common
module-init-tools
ondemand
pppd-dns
procps
rsync
sysklogd
udev
udev-finish
x11-common
acpid
avahi-daemon

but are they all needed?

at least, I think avahi-daemon, x11-common, rsync should be disabled
for standard server (e.g. apache, mysql etc)

Any comments?

Thanks.
