initial DNS zone transfer too slow, too slow to update, any configuration to speed it up?
Clash Royale CLAN TAG#URR8PPP
I have configured a master/Slave zone, the initial zone transfer is too slow and no changes have happened over the course of 10 mins, the only update I have seen so far is 2 updates, this is in a test VMs and not production, there is hardly any data in it. Could it be a misconfiguration, I have changed TTL, refresh, retry to 100, yet nothing happens, tried bumping up the serial as well to get an update, no change. The first time I got it working it was quicker, now I repeated the same setup with a new IP and it's too slow. I have read this and have added it in my zone files as well, still it's dead slow.

Anything else I should do to speed up the initial update ?

It took about 30 minutes to complete the zone update, if someone could explain what happens in the background that takes this much time, that would be great..

It would help to say which dns software you are using. After that you should say what commands you run after you update the master to encourage the slave to get the updated data.

Sorry didnt realize that, I'm using the BIND v9, the command to update is named -u named -g -p 53 to get the Slave to update..
– Huud Rych
Dec 31 '18 at 23:15
named -u named -g -p 53runs the named command in the foreground. My understanding is these days you want to runrndcwhen you change the data, but I haven't usedbindin decades.

Did you change the serial number before you did the reload?

I found the problem to be ipv6 configuration which kept on attempting to update the zones as well, this was found in /var/log/messages log file, and since it was pre-configured in its default setting, it would keep on attempting to update zone right after ipv4 is updated thus no response was even received.
Removed all references of ipv6 from /etc/named.conf, and added the following options to /etc/sysonfig/named file.
RESOLVCONF=yes
OPTIONS=-4
Now it updates instantly.
