Host reverse resoling does not seem to right. I have: Zone name: whale.private. Active zone: TRUE Authoritative nameserver: work1.whale.private. Administrator e-mail address: hostmaster.whale.private. SOA serial: 1485797688 SOA refresh: 3600 SOA retry: 900 SOA expire: 1209600 SOA minimum: 3600 Allow query: any; Allow transfer: none; Zone name: 28/48.10.5.10.in-addr.arpa. <= this here is like non-usual, I understand it's how such a reverse subnet should be defined, but not 100% sure. Active zone: TRUE Authoritative nameserver: work1.whale.private. Administrator e-mail address: hostmaster SOA serial: 1485790340 SOA refresh: 3600 SOA retry: 900 SOA expire: 1209600 SOA minimum: 3600 Allow query: any; Allow transfer: none; but: ~]$ host 10.5.10.55 Host 55.10.5.10.in-addr.arpa. not found: 3(NXDOMAIN) and when I try to install a replica: ~]$ ipa-replica-install --setup-dns --no-forwarders --setup-ca Password for <a class="moz-txt-link-abbreviated" href="mailto:admin@WHALE.PRIVATE">admin@WHALE.PRIVATE</a>: ipa : ERROR Reverse DNS resolution of address 10.5.10.55 (work1.whale.private) failed. Clients may not function properly. Please check your DNS setup. (Note that this check queries IPA DNS directly and ignores /etc/hosts.) I understand it's all in DNS, so.. how to tweak it, to fix it? many thank, L. </body> </html>
