Anyone got a better idea ?

For servers that run from inetd, just edit inetd.conf and either `/etc/init.d/inetd restart` (or `killall -HUP inetd`) to make inetd reread its configuration. No reboot is necessary. For standalone servers, `/etc/init.d/ stop` will shut it down until the next reboot (or runlevel change). Follow that up with update-rc.d (read the man page) if you want to disable it semi-permanently. -- SGI products are used to create the 'Bugs' that entertain us in theatres and at home. - SGI job posting Geek Code 3.1: GCS d? s+: a- C++ UL++$ P++>+++ L+++> E- W--(++) N+ o+ !K w---$ O M- V?

You'll have to save the original non- default runlevels and two-digit sequence code used by init to decide which order to run the scripts in. When defaults is used the service starts in runlevels 2345 and stops in 016 and the links will have sequence code 20. You will need to explicitly specify anything that does not have these default values.

This prevents them from being loaded. Essentially the same thing as you do, but I think that this way the script is going to be deleted if the package it belongs to is removed. -- Arcady Genkin Don't read everything you believe.

Why don't you do (as root) "update-rc.d -f service-name remove" and later, when you want to enable it again, do a "update-rc.d service-name defaults"?

Try finding the line in the file /etc/inet.conf and comment it out for the
services that you don't want to run. You may have to reboot then, or try
restarting the internet superserver - try a "/etc/init.d/inetd restart". You
might have to kill a few other processes or just stop them using their scripts
in /etc/init.d/.
Hope this helps

Turning off services SOLVED
At various times I have wanted to turn off certain daemons without
uninstalling their packages. I couldn't find any good way to do this,
so I wrote a little script. I'm making it available under the GPL.
I've since discovered that the some packages also create a bunch of
crontab jobs, and they are still cluttering things up a bit.
If there's a better way to do this, I'd love to hear it.
