All, Have two servers. One has BIND8, the other BIND9.
Copied over the zone files from the BIND8 server to the BIND9 server, so they are identical. Updated the /etc/resolv.conf file and the named.conf file. When I do an nslookup (from a third server) pointing to the BIND8 server, it works fine: # nslookup > server 10.179.193.6 Default server: 10.179.193.6 Address: 10.179.193.6#53 > set debug=all > 10.16.42.61 Server: 10.179.193.6 Address: 10.179.193.6#53 ------------ QUESTIONS: 61.42.16.10.in-addr.arpa, type = PTR, class = IN ANSWERS: -> 61.42.16.10.in-addr.arpa name = ama552D.example.com. ttl = 86400 AUTHORITY RECORDS: -> 42.16.10.in-addr.arpa nameserver = abby.example.com. ttl = 86400 ADDITIONAL RECORDS: -> abby.example.com internet address = 10.179.193.6 ttl = 86400 ------------ 61.42.16.10.in-addr.arpa name = ama552D.example.com. # When I do the same pointing to the BIND9 server, it doesn't work: # nslookup > server 10.179.221.13 Default server: 10.179.221.13 Address: 10.179.221.13#53 > set debug=all > 10.16.42.61 Server: 10.179.221.13 Address: 10.179.221.13#53 ------------ QUESTIONS: 61.42.16.10.in-addr.arpa, type = PTR, class = IN ANSWERS: AUTHORITY RECORDS: -> 16.10.in-addr.arpa origin = prisoner.abc.org mail addr = hostmaster.root-servers.org serial = 2002040800 refresh = 1800 retry = 900 expire = 604800 minimum = 604800 ttl = 10608 ADDITIONAL RECORDS: ------------ ** server can't find 61.42.16.10.in-addr.arpa.: NXDOMAIN Server: 10.179.221.13 Address: 10.179.221.13#53 ------------ QUESTIONS: 61.42.16.10.in-addr.arpa, type = PTR, class = IN ANSWERS: AUTHORITY RECORDS: -> 16.10.in-addr.arpa origin = prisoner.abc.org mail addr = hostmaster.root-servers.org serial = 2002040800 refresh = 1800 retry = 900 expire = 604800 minimum = 604800 ttl = 10608 ADDITIONAL RECORDS: ------------ ** server can't find 61.42.16.10.in-addr.arpa.: NXDOMAIN > ama552d.example.com Server: 10.179.221.13 Address: 10.179.221.13#53 ------------ QUESTIONS: ama552d.example.com, type = A, class = IN ANSWERS: AUTHORITY RECORDS: -> example.com origin = monty.example.com mail addr = admin.example.com serial = 134 refresh = 900 retry = 600 expire = 86400 minimum = 3600 ttl = 2991 ADDITIONAL RECORDS: ------------ ** server can't find ama552d.example.com: NXDOMAIN Server: 10.179.221.13 Address: 10.179.221.13#53 ------------ QUESTIONS: ama552d.example.com.example.com, type = A, class = IN ANSWERS: AUTHORITY RECORDS: -> example.com origin = monty.example.com mail addr = admin.example.com serial = 134 refresh = 900 retry = 600 expire = 86400 minimum = 3600 ttl = 3558 ADDITIONAL RECORDS: ------------ ** server can't find ama552d.example.com: NXDOMAIN Also did a dig pointing to the BIND8 server: # dig @10.179.193.6 ama552d.example.com ; (1 server found) ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 44601 ;; flags: qr aa rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUESTION SECTION: ;ama552d.example.com.
