[opensuse-arm] LAN: DHCP vs. fixed addr.
After I install openSUSE-Leap-15.1-ARM-XFCE-raspberrypi3.aarch64-2019.05.17-Snapshot1.18.raw.xz to a RasPi I get a IP via DHCP during the first boot. Then I configure a fix IP via YaST. But this fix IP is configured as secondary IP. Even if I remove the interface configuration and renew it with the fix IP - after the YaST config runs throught, there are a interface with a primary addess from DHCP and a additional secondary IP from the fixed config. Where i can change this tricky behavior? Bernd -- To unsubscribe, e-mail: opensuse-arm+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-arm+owner@opensuse.org

Bernd How do you configure it? Looks like you added a connection instead of editing

It seems that I found the trick. Ootb the NetworkManager is active. But if you enter the YaST lan part you did not get an hint as in openSUSE for x86_64. So two configs fight each other. I remove the NetworkManager (zypper rm -u Networkmanager) and now it get only my configured address without an additional IP from DHCP.

IIRC, Network manager is the default on XFCE images, but YaST should warn about it. Could you open a bug report for that, and cc me, please? Thanks, Guillaume
