--- Comment #3 from Tambet Ingo tambet@novell.com 2009-10-05 00:44:06 MDT --- I accidentally broke it - When netconfig doesn't exit successfully (doesn't return 0) NM now writes /etc/resolv.conf. That usually happens if you have manually changed /etc/resolv.conf and netconfig refuses to change it, as described in the comments.

I'll revert that change.

--- Comment #4 from Marius Tomaschewski mt@novell.com 2009-10-05 01:32:09 MDT --- This is a very bad idea to write it yourself when netconfig reports != 0. First, because you break netconfig, second, because you overwrite manual user setting. Complaining to the user would be much better here.

See also feature #306274: Implement <dns|nis|ntp> filter for netconfig update and use it in yast2

it has been rejected for 11.2 because of not enough time/resources, but I'll implement it this week for SLE-11 SP1 anyway and if Stephan agrees, we can apply this change to 11.2, to improve this scenario.

Basically, "netconfig update -m dns -f" will force DNS setting update. When "netconfig update" - or better "netconfig update -m dns" - fails, the GUI can inform the user about and ask if he/she wants to force to overwrite the current (manual) DNS settings. When the user gives his OK, the GUI can call the above command incl. -f.

Currently, the way to go would be e.g.: cp /dev/null /etc/resolv.conf ; netconfig update but it does not work properly e.g. in NETCONFIG_DNS_FORWARDER=bind or dnsmasq mode, because the resolv.conf is not the only file written then... So at the moment the GUI can only use "netconfig update -f", what may throw away e.g. user's manually configured NIS settings...

Added Stephan to Cc. Tamber, please set NEEDINFO to Stephan when this feature would be helpful here.

Problem with loosing user settings can be worked around if netconfig creates backup of resolv.conf before writing new, so that user can combine both. Not a solution, but better then starting from scratch.

This bug was not about loosing user settings because netconfig would overwrite it, but about NM writing the resolv.conf directly without to use netconfig and ignoring the (user) policy for resolv.conf updates.

Netconfig does not overwrite any user settings /etc/resolv.conf, there is no work around/backup needed. It generates resolv.conf.netconfig in such cases.

Generally, user settings should go to the yast2 network module and then to network/config or NetworkManager GUI to some place where NM stores them. The backup of all sysconfig files is created at /var/adm/backup/sysconfig. Alternatively, the user can set NETCONFIG_DNS_POLICY='' and maintain the resolv.conf and related files himself.

--- Comment #12 from Tambet Ingo tambet@novell.com 2009-10-16 00:41:49 MDT --- Did you upgrade to RC1 or did you perform a clean install? The problem with upgrading is that you have the /etc/resolv.conf created by NetworkManager and netconfig refuses to touch it. This problem existed only in one milestone and won't affect people who will upgrade from 11.1 to 11.2. This problem can be fixed by running 'sudo /sbin/netconfig update -f' once. Can you confirm this fixes your problem?

Marius, the man page for netconfig does not mention resolv.conf.netconfig. How about adding a note like:

"In some cases, netconfig will not overwrite foo.conf and will save the data to foo.conf.netconfig instead. Use netconfig update -f to overwrite foo.conf." (FIXME: would simply "mv foo.conf.netconfig foo.conf" work? If not, why?)

--- Comment #18 from Rajko Matovic rajko@opensuse.org 2009-10-18 07:16:03 MDT --- It is not the same issue.

This one was about NetworkManager writing /etc/resolv.conf which goes against policy to use netconfig.

The other 546213 is about NetworkManager update not taking care of the problem created with this bug. NM version of /etc/resolv.conf was still in place and netconfig refused to change it.

Marius, the man page for netconfig does not mention resolv.conf.netconfig. How about adding a note like:

"In some cases, netconfig will not overwrite foo.conf and will save the data to foo.conf.netconfig instead. Use netconfig update -f to overwrite foo.conf." (FIXME: would simply "mv foo.conf.netconfig foo.conf" work? If not, why?)

Yes, it should be added to the man page.

Yes, basically the "mv foo.conf.netconfig foo.conf" just works. Problem is to know which "foo" :-) In case of DNS, this could be the /etc/resolv.conf or /etc/resolv.conf and /etc/named.d/forwarders.conf.

So "netconfig update -f" is the better.

The feature #306274 (comment #4) will allow to select/filter the operation scope by (module name or) module group basis:

netconfig update -m dns -f

will "make the mv" for all currently required files without to touch e.g. NIS where the user maybe wants to keep his manual adjustments.
