Hi -- I'm just getting started with pdns on ubuntu edgy. I installed it using synaptic, which also starts the daemon. I tried a bunch of stuff, e.g. using firefox to visit several websites, then stopped firefox, lauched it again and did the same thing again. Finally, I did this:
pkill -SIGUSR1 pdns After doing so, the output of tail /var/log/syslog is: Jan 18 11:42:25 localhost pdns_recursor[9264]: stats: 3 questions, 41 cache entries, 2 negative entries, 0% cache hits Jan 18 11:42:25 localhost pdns_recursor[9264]: stats: throttle map: 0, ns speeds: 0 Jan 18 11:42:25 localhost pdns_recursor[9264]: stats: outpacket/query ratio 225%, 0% throttled, 0 no-delegation drops Jan 18 11:42:25 localhost pdns_recursor[9264]: stats: 0 outgoing tcp connections, 0 queries running, 0 outgoing timeouts So I guess it is not really working, since there are no cache hits. Naturally I want to get it to work, so I'm wondering: 1. Where is the cache stored? Can I vew it? 2. Why am I not getting any cache hits?
