[Vivekdubey]

I have a problem in rhel5 dns configuration:
I have done dns configuration succesfully .
I have problem in only the updation of slave dns that i configure slave and in master dns i entered the allow update(ip;);
but the slave not updating
Please any one give me the reason that why the salve cannot updating
I configure both the both master and slave dns correctly and i have checked it by named-checkconf and named-checkzone

check  your named.config  file :

> Master:
>
> options {
>
>         directory "/var/named";
>
>         pid-file "/etc/named.pid";
>
>         allow-query { any; };
>
>         allow-transfer {xx.xx.xx.xx ; }; //Slave DNS IP
>
>         notify yes;
>         also-notify {xx.xx.xx.xx; } //Slave DNS IP

You shouldn't need this if the slave is already listed in the NS
records.  This is only supposed to be fore additional slaves that aren't
listed.
