How to prevent avahi-daemon from starting

rng · 01-04-2014, 02:57 AM

I am running kubuntu-13.10 which is otherwise working well. I want to stop/remove avahi-daemon and I tried command: /etc/init.d/avahi-daemon stop . However, it remains active as I see it with the command 'netstat -apute'. How can I stop it from running at startup? I do not see it in system-settings > serviceManager listed daemons. I tried to remove it but it wants to take cups etc with it and I suspect the printer will not function after that.

Thanks for your help.

Code:

(sudo) /etc/init.d/avahi-daemon stop

if file exists would only stop the service this session

what you are looking for is a way to stop it completely?

does that mean you don't need wireless discovery or printer network discovery?

in Debian the gui package =bum can stop start ups or if you like commands install the package= sysv-rc-conf

but me thinks *buntu now use systemd?

I want to disable avahi-daemon so that it does not start at startup. My desktop is connected through usb to a local printer+scanner and I do not need to search for printers etc on any network. I tried following but none of them work:
* sudo gedit /etc/default/avahi-daemon ; Change the line: AVAHI_DAEMON_START = 1 to: AVAHI_DAEMON_START = 0 ; Reboot your system
* /etc/init.d/avahi-daemon stop (in rc.local)
* service avahi-daemon stop (in rc.local)
* sudo update-rc.d -f avahi-daemon remove
* sudo gedit /etc/avahi/avahi-daemon.conf ; change use-ipv4=yes to: use-ipv4=no ; then: sudo /etc/init.d/avahi-daemon restart
* avahi-daemon is already unselected in rcconf application

The kubuntu 13.10 does not have systemctl command so I presume it does not have systemd.

does it have packages?
bum
sysv-rc-conf

'bum' package was not installed but I installed it. It shows an avahi-daemon entry. The activate checkbox on left is not ticked. Under the 'Running' status column, there is a white bulb present (rather than '-' or black bulb). On right clicking there are 2 options: 'Activate & apply now' and 'Stop now'. I stopped it but its status remained the same and the commands 'netstat -apute' and 'ps aux | grep avahi' both show that avahi-daemon is still running.

I have not yet tried sysv-rc-conf.

don't forget to run it as root or sudo

Running bum with sudo did not make any difference. I then installed and ran with sudo the sysv-rc-conf command. Avahi-daemon is not selected for any runlevel. I stopped it with '-' key. However, avahi-daemon is still running as seen on 'netstat -apute' command.

you do not stop it pls

you unselect it by pressing space bar where ever it appears as a check

as per attached image

then reboot to check its no longer loading for your run level (most likely level 5)

rng · 01-05-2014, 07:22 PM

As I mentioned earlier, it is not checked in any runlevel (see attached screenshots). Also, cups and networking are not checked but they are all running. So all these must be getting loaded later.

do you have a wifi device?

rfkill might run to enable avahi-daemon

you could try booting up and running

top or htop to find the daemon is not running and then do something and it might start

lsof command might show it?

rng · 01-06-2014, 12:36 AM

I do not have a wifi device. 'top' command does not show avahi-daemon to be there, though it is present on 'ps aux | grep avahi', 'netstat -apute' as well as 'lsof' commands.

If I try to purge/remove avahi-daemon (that seems to be the only way to stop it), it wants to take away following packages also:

Code:

bluez-cups* cups* cups-browsed* cups-daemon* hplip* libnss-mdns* printer-driver-gutenprint* printer-driver-hpcups* printer-driver-postscript-hp* telepathy-salut*

I suspect I will not be able to use my HP PSC 1410 printer-scanner which is connected with usb to this desktop. Is there any way I can use the printer after removing above packages?

cups-browsed uses avahi-daemon EDIT but it looks like

for the moment try removing all saned* from your runlevels using sysv-rc-conf
full reboot and report

good luck

do not delete the packages.....you can manually start a daemon when you need to scan

rng · 01-06-2014, 01:34 AM

As shown in my attachments above, both cups and cups-brow$ are already unselected from all runlevels.

aus9 · 01-06-2014, 03:44 AM

yes I can see that thanks I editted to suggest saned
but avahi is normal to have for cups now a days...when you want it

2) Do you have a NFS share setup

3) do you have anything inside rc.local?

aus9 · 01-06-2014, 03:47 AM

just found a way thru google to see what depends on it....YMMV

Code:

deborphan -a avahi-daemon 
avahi-daemon (main/net)
      sane-utils
      libsane
      pulseaudio-module-zeroconf
      cups-daemon
      hplip
      cups

I bet when you play sound......pulseaudio wakes up and starts it
