View Full Version : Knoppix 7.4 DNS process acting peculiar.

I find that IceWeasel 32.0.3 browser in Knoppix 7.4.2 LiveUSBs often appears to
get confused on doing DNS translations, and needs a wifi disconnect and re-connect
to get surfing going smoothly again.

These re-connects go pretty fast, but I don't remember having to keep tweaking
the system this way with 7.2 and earlier Knoppixes.

Is anyone else having similar symptoms?
Any ideas about what might be going on here would be appreciated.

I gather that perhaps enabling NetworkManager-wait-online.service
may be what's missing in the current systemd set-up for Knoppix.
See for example:
https://wiki.archlinux.org/index.php/NetworkManager#Enable_NetworkManager_Wait_Online

To see how this might be done, see for example:
http://unix.stackexchange.com/questions/106656/how-do-services-in-debian-work-and-how-can-i-manage-them

So, as root, I entered:


root@Microknoppix:/home/knoppix# systemctl list-unit-files | grep wait-online
and I got:
NetworkManager-wait-online.service disabled
systemd-networkd-wait-online.service disabled

Then I entered:
root@Microknoppix:/home/knoppix# systemctl enable NetworkManager-wait-online.service
root@Microknoppix:/home/knoppix# systemctl list-unit-files | grep wait-online
and then I got:
NetworkManager-wait-online.service enabled
systemd-networkd-wait-online.service disabled


We'll give this a try and see if this helps the situation.

It turns out the 'NetworkManager' in Knoppix is really knoppix-networkmanager,
and there is no 'wait-online' aspect in its definition.
Whether this approach might work with an 'all-up' NetworkManager is moot.

Wicd is mentioned in some places as an alternative to NetworkManager which
solves some problems, not clearly the one at hand. That alternative would
require removal of any current 'NetworkManager' and installation of Wicd as
its replacement. Whether that might solve the problem at hand is also unknown.

It may just be the case that systemd and knoppix-networkmanager have this
small problem which at present either doesn't occur for many other users,
or occurs at such a rate as not to be a problem worth addressing. Something
on the order of the disappearance of frame controls allegedly caused by a
minor incompatibility of Compiz and some aspect of LXDE.
