[server] automatically bring ethernet connection back up when router is rebooted

Hi everyone :slight_smile:

I’ve been using Debian based distros on my server and laptop for a few years now but I’m very new to opensuse, so please forgive me if I’m asking silly questions.

I installed opensuse 13.2 on my backup server a couple of months ago, which is an Intel NUC connected to a home router with an ethernet cable.

The problem is that if the router is rebooted or the connection drops, the ethernet connection doesn’t automatically reconnect.

I originally configured the ethernet adapter in Yast. Exploring Yast further, it seems that all the network settings are handled by Wicked.

Am I right in thinking that all I need to do is:

sudo cp /etc/wicked/common.xml /etc/wicked/local.xml

…and then in the new file, change




…and then

sudo wicked ifup all


I want to be sure because I don’t have physical access to the server right now, so if I mess it up I’ll be stuck.

Also, where are the actual configuration files for the ethernet adapter I configured in Yast? E.g. with NetworkManager they would be in /etc/network/interfaces ?


AFAIK, all you need to do is change the use-nanny option in common.xml and ensure the wickedd-nanny service is enabled and running…

To see theethernet info use;

wicked show all

Thanks! I’ll give it a shot.

I have another related question…

My first instinct was to install NetworkManager because I know it handles reconnection fine, but it seems I can’t do that because one of the dependencies conflicts with the minimal installation. I don’t want to install a whole DE on the server.

If I did choose to install NetworkManager, how could I solve the NM dependency problem without installing a whole DE (I’d like to understand how to work around problems like this one even if it’s not required right now).


For the record, if you create local.xml by copying common.xml, you need to remove the self-reference at the bottom of the file (this part):

<include name="local.xml" optional="true" />

Probably easier to just create the file from scratch and fill it with:


For your specific scenario
I’d recommend (untried!)

Installing the MinimalX “Desktop.”

The Minimal X (aka IceWM) is hardly more than the text-only “server” option but is less adamant about that “patterns-openSUSE-minimal_base-conflicts” which is a problem you might run into often without any Desktop.

You won’t get a bloated Desktop, in fact you’ll find that if you do log in to the Minimal X desktop you won’t find much of anything installed by default… mainly a window manager and a console and nothing more.


Thanks, I hadn’t considered doing something like that!

If I install Minimal X, I guess I can also run programs like Firefox with SSH + X forwarding? That might just be the perfect balance!
