    Question about the avahi-daemon

    .
    I note on syslog, using Knoppix 7.2 LiveUSB, there is always a time-out at boot,
    waiting for avahi to do something.

    Also, there's this note which seems tempting:
    http://askubuntu.com/questions/40292...e-avahi-daemon

    Is there any reason NOT to disable the avahi-daemon if one doesnt need
    to access network services?

    Within Knoppix 7.2 avahi-daemon isn't enabled per default.

    With "/etc/init.d/avahi-daemon status" you'll get the message:
    Avahi mDNS/DNS-SD Daemon is not running

    (from the link in post #1)
    dbus[991]: [system] Failed to activate service 'org.freedesktop.Avahi': timed out

    This means that it failed to connect to the service since it's not running. The 30 seconds you spend waiting is not because the service is starting, is because another process expects the service to be running when dbus tries to access the key. If you want to really stop Avahi you should instead remove the package:

    sudo apt-get remove avahi-daemon

    There isn't a sane way to deactivate the daemon without messing with other networking services.

    Similar to my situation.

    Perhaps here are more clues (typical syslog beginining at end of startup and getting on-line):

    I've read the link you've posted; but the question there has been, how to deactivate avahi-daemon. In Knoppix the daemon isn't active.

    But it isn't worth to wail over avahi. In my example of syslog you can see the last successfull action of dbus at 17:24:32. Many things happen in the intervall from 17:24:32 to 17:24:49. (There is no printer connected to Knoppix.)

    At 17:25:03 I get the "failed" message from dbus. Therefore the "lost" time is about 14 seconds for me.

    Code:
    Jun 30 17:23:59 Microknoppix syslogd 1.5.0#6.2: restart.

    Greetings, Werner.

    Thanks for your comments.

    I have to admit my boot time now takes (only) 71 seconds,
    but IIRC, when my LiveUSB was 'new' it only took 50 seconds.

    71 seconds is only considerable when compared to my Win7
    which still gets online in 50 seconds.

    The reference suggests maybe 30 seconds are lost on an avahi timeout.

    I'm not aware what I've done to add 21 seconds,
    but it looks like perhaps I'm not handling avahi correctly.
    Maybe it should be ON by default in my case.

    This times are of no use. You have to messure the time from booting Windows7 or Knoppix up to the time you can really work with an OS: for example the end of start and stop of notepad within Windows or leafpad within Knoppix. And you have to differ,if you ar booting an OS from HD or USB-srick.
    Code:
    Jun 30 06:39:27 Microknoppix NetworkManager[2616]: <info>  Activation (wlan0) Stage 4 of 5 (IPv6 Configure Timeout) complete.
    Jun 30 06:39:45 Microknoppix dbus[2492]: [system] Failed to activate service 'org.freedesktop.Avahi': timed out
    In your example I see a delay time of about 18 seconds.

    In the meantime I did some measurings using my laptop, always from boot the OS to stop of the editor:

    Knoppix 7.2 on USB stick 8GB => 44 sec.
    Knoppix 7.3 on USB stick 8GB => 36 sec
    Knoppix 7.2 HD install => 34 sec.
    Windows 7 => 57 sec.

    Knoppix 7.3 is optimized with its boottime In comparison with 7.2. And what I've seen: within 7.3 avahi-daemon is also not running, but dbus doesn't look and wait for avahi. But don't ask me, if we also can have this behaviour in 7.2.

    Thanks again, Werner.
    Perhaps 7.4 will improve things a little for me.
