Hi Bind Users, Any one familiar with the error we encountered on DNS BIND 9.18.2 Ubuntu for DNS Caching, below;
We are using RPZ for redirecting domains (porn sites) where we already have 20k+ entries. The domain (globem2m.com.ph) from below logs is not in the RPZ list but was processed for RPZ QNAME rewrite, based on the logs, and query to that domain results to SERVFAIL. The issue is isolated to several domains only including globem2m.com.ph, all other queries to different domains are successful. To resolve this issue, we have to flush cache or restart the BIND service. root@bind# nslookup globem2m.com.ph <server ip> ** server can't find globem2m.com.ph: SERVFAIL Trace logs: : query (cache) 'globem2m.com.ph/A/IN' approved : rpz QNAME rewrite globem2m.com.ph stop on qresult in rpz_rewrite(): failure : query failed (failure) for globem2m.com.ph/IN/A at query.c:7657 fetch completed at resolver.c:4053 for globem2m.com.ph/A in 0.000000: failure/success [domain:com.ph ,referral:0,restart:1,qrysent:0,timeout:0,lame:0,quota:0,neterr:0,badresp:0,adberr:2,findfail:0,valfail:0] : reset client : servfail cache hit globem2m.com.ph/A (CD=0) : query failed (SERVFAIL) for globem2m.com.ph/IN/A at query.c:6949 : reset client Thank you, Wil -- This e-mail message (including attachments, if any) is intended for the use of the individual or the entity to whom it is addressed and may contain information that is privileged, proprietary, confidential and exempt from disclosure.
