DNS refresh replication

[carlos123]

Hi all,

I have a DNS CentOs 7 with Bind. Nothing else, just for testing purposes. The domain worldculturesweek.com has the glue ns1 and ns2 records pointing to my server IP wich is not behind NAT. All this is working fine.

The /var/named/worldculturesweek.com file contains:

Code: Select all

$ttl 1800
@       IN      SOA     worldculturesweek.com. hostmaster.worldculturesweek.com. (
                        2017071401      ;Serial, todays date + todays serial #
                        1H              ;Refresh
                        1H              ;Retry
                        1W              ;Expire
                        1H              ;Minimum
)
;Nameservers
         IN     NS              ns1.worldculturesweek.com.
         IN     NS              ns2.worldculturesweek.com.

;Resolve Nameserver IPs
ns1     IN      A       82.163.78.33

;Define hosts resolutions

mail    IN      A       82.163.78.33

MX records
worldculturesweek.com.     IN      MX      10      mail.worldculturesweek.com.

;CNAMEs
www     IN      CNAME   @

My issue is if I make any change and I also change the serial and run the command "rndc reload worldculturesweek.com" or "systemctl start named" and I run "dig worldculturesweek.com" I see the initial serial (2017071301).

Heres the output of the dig command:

It's like the named service doesn't reads the modified file. I know it is the right one because before it starts working I had a syntax issue and I edited this same file.

Any clues?. Thanks.
