Slave Question

Hi:

I have a question about slave DNS server, The slave dns server continue working when the master dns server is down.

I configure the master and it work fine named version 8. and the slave is 9.0

The error is:
nslookup
*** Can't find server name for address 7.10.6.24: No response from server
*** Can't find server name for address 7.10.6.25: Non-existent domain
*** Default servers are not available
Using /etc/hosts on: server03

The error is when the master dns server is down.

Thank you!!

I've never tried running master and slave DNS servers at different releases but this shouldn't be a DNS server issue but rather a DNS client problem. You appear to have problems with reverse lookups. Are your secondary DNS servers listed in this client's /etc/resolv.conf file?

Also - are your slaves configured to transfer the reverse zones?

Not too sure if your last post was a question or not...

On the master, in /etc/named.conf, there should be a "allow-transfer" under the reverse zone(s) for the ip's of those slaves (or a range)...

Then on the slaves, you should see the reverse zone files in /etc/namedb (r what have you in /etc/named.conf for directory "/etc/namedb";).
