*Not* starting services at bootup
Posted by Utumno on Tue 15 Aug 2006 at 09:50
Tags: none.
I've got a couple of services ( most notably Samba, mldonkey-server ) which I do not want to start at system bootup. So I 'update-rc.d -f XXXX remove' those services from the initscripts.

The annoyance: every time I 'apt-get upgrade' the system and a given service gets upgraded, it adds itself back to the initscripts. Anyone knows how to prevent that?

This might help.

Ok, seems like changing all the 'S' links to 'K' ( rather than removing them altogether with update-rc.d remove ) will solve my problem. Thanks.

**pining for BSD-style initscripts***

Always works: just do `chmod -x /etc/init.d/service-name` - no need to change the default installation ;-)...

that does not work *always*... Does not work in my situation, for one.

The reason I do not want to have Samba started at bootup is that the laptop we are talking about is typically run in two places ( my office and my house ) and in my house I do not need nor want to run it. The network there is very hostile and filled up to the brim with script-kiddies - after a week of running samba there ( accidental, that was after an 'apt-get upgrade' and my failure to notice that this re-adds samba to initscripts ) my /var/log/samba/* directory was over 100 MB of breakin attempt logs.

So I had to write a script which first detects where I am and only if I am in the office it brings samba up with a '/etc/init.d/samba start'. So no, a 'chmod -x' wont do.

Surely in that situation you're fine:

  • The bootup script is non-executable.
  • You run your "where am I script" which either:
    • 1. Identifies it needs to start samba and runs "chmod +x ; start; chmod -x"
    • 2. Realises nothing needs to happen so does nothing.

The only extra complication I see is that once you've identified that you need to enable Samba you must start it, but remove the -x permission so that at reboot time it doesn't come back up unless your identification script detects that this is required.

Well, yeah, but... What about other services then, like mldonkey-server, which I only want to start manually? with this solution I would have to write a wrapper-script to start it the 'chmod +x;start;chmod -x' way. The same for all the other services which I do not want to start on bootup. This is of course perfectly doable, but I was hoping for some more generic solution.

I guess the real question is the following: why is that an upgrade re-adds a service to initscripts anyway? Seems like if a service is installed, and if the default behavior is to start it on bootup *but* during the upgrade it turns out this service is currently set *not* to be started on bootup , it can only mean one thing: the administrator of this machine must have update-rc.d remove'd it, and he must have done it on purpose. So why the forceful override of administrator's choice?

What about doing:

sh /etc/init.d/<service-name> start

?

That should work for those services that you want to start manually -- if you go with the non-executable scheme that is.

Cheers.

What I did on my laptop and what works great is the following : 
# update-rc.d samba stop 0 1 2 3 4 5 6 .

This is exactly what was suggested in this debian-user post pointed at by Steve: changing all the 'S' links to 'K' links. I did exactly that and so far it seems to work :)

I went round and round with this on debian-user a year or so ago. My final solution was to use John Hasler's tool sysvconfig to administer init scripts.

Oh, in case of mldonkey, best is to simply edit /etc/default/mldonkey-server and set 'LAUNCH_AT_STARTUP' to false... No such file for Samba, though.
