I installed time ago unbound. After having done some adjustment (the dns resolution would be disturbed by settings of "automatic" in /etc/sysconfig "DNS Policy" (which i did set to "", and since then the "outages" I experience with unbound were gone) all was fine. Still rarely(!) it happens that something that seems "unrelated" to unbound "crashes". No error in unbound log, clean connection with the wlan, but no name resolution. A complete system restart does help. Only restarting unbound as service does not. So something that is in the middle between unbound and network does not function as it should (or at least I do not know how to restart it when it blocks). Normally I did sudo rcnetwork restart and that would restart the network. Now it appears that, although the network is restarted, the problem is not solved. Not even restarting unbound and rcnetwork. So what do I have to restart, some systemd thing? Last question: For what is /etc/sysconfig/"netconfig modules", with unbound, what should I insert there in yast, edit /etc/sysconfig as value for unbound? I guess: dns-resolver -dns-bind -dns-dnsmasq nis ntp-runtime (should do) but do I also "-" dns-resolver so all is done by unbound? or does the dns-resolver relies on unbound? What is the value to be set for unbound module: dns-unbound? (if anybody knows). Currently it is simply started by system services at startup, so maybe no extra value for it in etc/sysconfig is needed at all? Thanks in advance.
