More Bind problems. Cache not updating

ACDII · 07-21-2011, 02:53 PM

Have a Master/Slave combo, the slave I believe gets its updates for external domains from the master. The master is not refreshing a zone that we know has changed. I did a reload of named, did not help, and in order to restart it, the server has to be rebooted. I don't know how it was setup, but named will not stop restart, it errors when you try to restart it.

Is there anything else I can do to find out why the zone isn't updating? A dig on the server shows the old nameservers for that domain, and nslookup on my PC to 4.2.2.1 shows the correct NS. What would prevent the server from obtaining the new records? The TTL has long since expired, and since this is a production server, I am reluctant to reboot it.

Hi,

What you mean by that? A slave gets updates from master for the zones it's authoritative for.

It could help if you mention the distro and the output of

Code:

ps -ef|grep named

To reload configuration without rebooting, you can try

Code:

killall -HUP named
or
kill -HUP <named pid>

You can check the logs in both master and slave. Also check the zone in question here
