Description Hendrik Woltersdorf 2017-07-02 18:10:45 UTC

After the update to Tumbleweed 20170630 the networkmanager does not write the ipv4 nameserver entry, it gets via dhcp, into /etc/resolv.conf.

My resolv.conf bevor the update:

search schlepptop.site
nameserver 192.168.0.2
nameserver fe80::ba27:ebff:fe32:1832%wlp6s5
nameserver fd89:be49:2148:1584::2

after the update:

search schlepptop.site
nameserver fe80::ba27:ebff:fe32:1832%wlp6s5
nameserver fd89:be49:2148:1584::2


All those addresses, ipv4 and ipv6, point to the same machine.

software versions:
NetworkManager-1.8.0-1.1.i586
NetworkManager-branding-openSUSE-42.1-1.10.noarch
NetworkManager-vpnc-1.2.4-2.2.i586
NetworkManager-pptp-1.2.4-1.3.i586
NetworkManager-applet-1.8.2-1.1.i586
libKF5NetworkManagerQt6-5.34.0-1.2.i586
NetworkManager-connection-editor-1.8.2-1.1.i586
NetworkManager-openvpn-1.2.10-1.1.i586

dhcp-client-4.3.3.P1-5.2.i586
dhcp-4.3.3.P1-5.2.i586

This forum post suggest that NM may fail to merge multiple responses from DHCP server:

Comment 2 Hendrik Woltersdorf 2017-07-02 18:28:22 UTC

Confirmed. If I put all options in /etc/dhclient.conf after "request" on one line, it works.

Works for me. Thanks for letting us know.
