[Bug 1342400] Re: avahi-daemon constantly reporting "Invalid response packet from host"

[Louis]

Hi - thanks for response! I have become quite set (read obsessed) on
fixing this even though I only see the error every 40secs and I filter
blocked  it out from polluting my syslog file.

I installed from the avahi-0.6.32.tar.gz using :
./configure
make
sudo make install

also  make clean (between recompiles)

pi at raspberrypi:~ $ sudo which avahi-daemon
/usr/local/sbin/avahi-daemon
pi at raspberrypi:~ $ sudo dpkg -l avahi-daemon

rc  avahi-daemon   0.6.31-5     armhf        Avahi mDNS/DNS-SD daemon


Also, stranger still, is that I totally commented out the suspected offending log line in the server.c file and recompiled the project - so this could be more about my lack of compiling skills than avahi issue??

            /*avahi_log_debug("Invalid response packet from host %s.",
avahi_address_snprint(t, sizeof(t), src_address)); */

Title:
  avahi-daemon constantly reporting "Invalid response packet from host"

Status in avahi package in Ubuntu:
  Confirmed

Bug description:
  After installing Ubuntu 14.04 (Release: 14.04) and looking for other
  information in /var/log/syslog, I see that syslog is being flooded by
  "Invalid response packet from host" messages from avahi-daemon.

  I searched around to see why this might be and ran across the following avahi mailing list post along with a patch to fix it:
  http://lists.freedesktop.org/archives/avahi/2012-July/002171.html

  >>>
  I would say you can safely ignore it, since any machine on your
  network running a recent OSX version will cause these messages.
  Here's a patch with what we change to avoid these messages flooding
  syslog.
