[Unbound-users] caching server only

[Christoph Kaminski]

Hi All

I want to setup a caching server only with unbound on each host what is
able to 'survive' some time without the forwarder. Forward und reverse
resolving should work. If it can reach the forwarder then it should ask
there for all records (@/A/PTR/CNAME/SRV). If it cant reach the forwarde,
then it should deliver the answers from cache. Is this config ok for this?

server:
cache-min-ttl: 0
cache-max-ttl: 86400
infra-host-ttl: 900
infra-cache-numhosts: 10000
do-ip4: yes
do-ip6: no
do-udp: yes
do-tcp: no
do-daemonize: yes
username: "unbound"
directory: "/etc/unbound"
use-syslog: yes
log-time-ascii: yes
log-queries: yes
pidfile: "/var/run/unbound/unbound.pid"
prefetch: yes
prefetch-key: yes
rrset-roundrobin: yes
minimal-responses: yes
