Default avahi is killing my network connection from time to time

Hi,

I am using 8.10 on my laptop. When I plug in the cable of the network only
after system boot I have reproducably problems with my network connection. I
dies all 10 minutes.

During an outage I find the following entries in syslog:

I don't see anything there out of the ordinary. avahi starts up when
your machine no longer has a 'real' IP, then removes itself when a
real IP is set up again.

I think you're barking up the wrong tree.

Tell us more about the symptoms. It's kinda interesting that it's
.49, then .51 10 seconds later.

Hi,

thanks for your answer.

But why does my computer loose the "real" IP? Nothing suspicious before
avahi withdrawing the address record in th logs.

Any why does this happen every 8 to 10 minutes.? Very annoying during work

Michael.

Not an avahi expert by any means, but I would think that avahi just
reacts to the IP being lost. I would focus on the first part of your
question, "why does my computer loose the "real" IP?"

Could you please deactivate Avahi by editing /etc/default/avahi-daemon
and rebooting? Then see if you still lose the IP

So it happens when you are using the wired connection. Just at work?
or at home too? Cable ok?
