When i add a DNS zone in ISPConfig, it get added, but domain did not resolve.

When i check the /var/named folder, i see the domain name with .err extension

[root@server named]# ll

drwxrwx---. 2 named named 4096 Dec 6 00:22 data

This is because ISPConfig check DNS zones with named-checkzone command. If it fail the check, it do not add the DNS zone, instead save the domain with .err extension.

[root@server named]# named-checkzone furu-anime.com /var/named/pri.furu-anime.com.err
zone furu-anime.com/IN: NS 'ns1.furu-anime.com' has no address records (A or AAAA)
zone furu-anime.com/IN: NS 'ns2.furu-anime.com' has no address records (A or AAAA)
zone furu-anime.com/IN: not loaded due to errors.
[root@server named]#


This in cause the DNS Zone file is missing entry for

ns1.furu-anime.com
ns2.furu-anime.com


To fix the problem, Go add A records for ns1 and ns2 in ISPConfig.

This happens when you add a domain name, that use its own name servers like ns1.yourdomain.com and ns2.yourdomain.com

Once you update DNS entry in ISPConfig, it take few minutes for DNS Zone to to recreate. This is done by cronjob, that run every minute.

[root@server ~]# crontab -l
* * * * * /usr/local/ispconfig/server/server.sh 2>&1 | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done
* * * * * /usr/local/ispconfig/server/cron.sh 2>&1 | while read line; do echo `/bin/date` "$line" >> /var/log/ispconfig/cron.log; done
[root@server ~]#

Once the error is fixed, zones file get named properly.

[root@server ~]# ls -l /var/named
