Slave zone for caching.
I just thought that creating a slave zone on my server for popular sites like google.com could save me bandwidth and improve the speed.
So I tried to create a slave zone using the system-config-bind tool
I first asked for the creation of a zone.
Specified it as class IN -> OK
Forwards -> OK
zone name -> google.com.
Then I specified the parameters for master zone servers as the IP addresses of ns1.google.com through ns4.google.com
Saved and service named restart.
And LO! google.com stopped working.
When I tried to preview the slave zone file, it was clean and empty. I tried to set the refresh time to a few seconds and restarted named in the hope that the slave would update from master in vain.
So I ultimately pruned the slave zone record to get google.com back.
Where could I have gone wrong?
Please help me.
