Hi Yesteday we lost connection to internet. I supposed that dns would be ok for our internal hosts. But unbound became very slow, sometimes did not respond at all. We use nsd and unbound.
What can I do to prevent this in the future? /etc/unbound/unbound.conf.d/ contains tree files: KSPT.conf qname-minimisation.conf root-auto-trust-anchor-file.conf KSPT.conf: server: verbosity: 1 interface: 0.0.0.0 access-control: 192.168.0.0/16 allow access-control: 10.0.0.0/8 allow access-control: 127.0.0.0/8 allow port: 53 do-ip4: yes do-ip6: no root-hints: "/etc/unbound/root.hints" cache-min-ttl: 300 cache-max-ttl: 86400 prefetch: yes num-threads: 1 minimal-responses: yes prefetch: no do-not-query-localhost: no local-zone: "domain.no" nodefault local-zone: "168.192.in-addr.arpa" nodefault local-zone: "10.in-addr.arpa" nodefault domain-insecure: "domain.no" domain-insecure: "168.192.in-addr.arpa" domain-insecure: "10.in-addr.arpa" private-domain: "domain.no" stub-zone: name: "168.192.in-addr.arpa." stub-addr: 127.0.0.1@1053 stub-zone: name: "10.in-addr.arpa." stub-addr: 127.0.0.1@1053 stub-zone: name: "spacetec.no" stub-addr: 127.0.0.1@1053 remote-control: control-enable: yes qname-minimisation.conf: server: # Send minimum amount of information to upstream servers to enhance # privacy.
