Happy new year :-) I set up a new server (DHCO+DNS+NFS) to replace my old one. During the setup with yast2 tools. After starting the services. named isn't working with following error messages: # systemctl status named.service ● named.service - Berkeley Internet Name Domain (DNS) Loaded: loaded (/usr/lib/systemd/system/named.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Fri 2021-01-08 11:39:15 CET; 11s ago Process: 18809 ExecStart=/usr/sbin/named.init start (code=exited, status=6) Jan 08 11:39:15 server systemd[1]: Starting Berkeley Internet Name Domain (DNS)...

According "dnssec-keygen --help" , "rsasha512" is a valid algorithm. Anyway I change it to big letters (RSASHA512), still unchanged. # systemctl status named.service ● named.service - Berkeley Internet Name Domain (DNS) Loaded: loaded (/usr/lib/systemd/system/named.service; enabled; vendor preset: disabled) Active: failed (Result: exit-code) since Fri 2021-01-08 11:56:56 CET; 13s ago Process: 19544 ExecStart=/usr/sbin/named.init start (code=exited, status=6) Jan 08 11:56:56 server systemd[1]: Starting Berkeley Internet Name Domain (DNS)...
