Symptoms

DNS zones are not synchronized between OBAS and an SSH-manageable name server. The server has Installed status, synchronization between OBAS and the name server can be performed successfully.

Nevertheless, all attempts to get a list of DNS records for some domain from the DNS server in question return empty response, like:

#dig @slave-dns.com domain.tld any
; <<>> DiG 9.8.2rc1-RedHat-9.8.2-0.30.rc1.el6_6.3 <<>>  @slave-dns.com domain.tld any
; (1 server found)
;; global options: +cmd
;; Got answer:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 60693
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 0, ADDITIONAL: 0

;; QUESTION SECTION:
;domain.tld.                         IN      ANY

Cause

OBAS server IP address is unreachable from the name server.

For each domain hosted on a name server registered in OBAS there is a record in the named.zones file on that server, for instance

#less /var/named/named.zones
....
zone "domain.tld" IN {
        type slave;
        masters { 192.0.2.2; };
        file "domain.tld.zone";
};
...

masters field contains a list of master name servers for a corresponding domain. For domains registered via OBAS there will be by default an IP address of the OBAS server taken from the SERVER_IP value stored in /etc/hspc/hspc.conf on the OBAS server.

If that address is unreachable from the name server in question due to network or firewall configuration or some other reason, DNS records will not propagate from OBAS to the name server.

Resolution

There are two ways to fix the issue:

  1. Make OBAS IP address reachable from the name server.

  2. Change the IP address of the OBAS server.
