Hi, I have some strange cached TTL on my pdns-recursor ( version 3.2-4 under debian ). When I query my recursor the TTL doesn't decrease by 1 second. Moreover the TTL never goes to 0 so the zone never expire in cache. As an example:
root@BBK2NS:~# dig soa google.com @89.2.0.1 ;; ANSWER SECTION: google.com. 569 IN SOA ns1.google.com. dns-admin.google.com. 1472387 7200 1800 1209600 300 ;; Query time: 0 msec ;; SERVER: 89.2.0.1#53(89.2.0.1) ;; WHEN: Thu Dec 29 10:02:46 2011 ;; MSG SIZE rcvd: 78 root@BBK2NS:~# dig soa google.com @89.2.0.1 ;; ANSWER SECTION: google.com. 40 IN SOA ns1.google.com. dns-admin.google.com. 1472388 7200 1800 1209600 300 ;; Query time: 0 msec ;; SERVER: 89.2.0.1#53(89.2.0.1) ;; WHEN: Thu Dec 29 10:02:47 2011 ;; MSG SIZE rcvd: 78 root@BBK2NS:~# dig soa google.com @89.2.0.1 ;; ANSWER SECTION: google.com. 562 IN SOA ns1.google.com. dns-admin.google.com. 1472388 7200 1800 1209600 300 ;; Query time: 0 msec ;; SERVER: 89.2.0.1#53(89.2.0.1) ;; WHEN: Thu Dec 29 10:04:08 2011 ;; MSG SIZE rcvd: 78 Is this a known bug on the recursor? Kind Regards Michael
