Re: [webmin-l] Cluster DNS

One 'bug' in Webmin at the moment is that when you add a record to a forward zone which triggers the addition of a corresponding record to reverse zone, <span style=3D"font-weight: bold;">both </span>zones need to be applied for the change to fully take effect. If you only click Apply in the forward zone, BIND will not reload the reverse zone.<br /><br />I am still working out a way to properly fix this ..<br /><br />=A0- Jamie<br /><br />On 10/Dec/2006 18:06 Grant Peel wrote ..

<div><br /></div>Webmin can do automatic reverse DNS entries in non-class-C
zones now .. it has been improved a lot since the book was written
:-)<br /><br />If your ISP delegates blocks smaller than a class C and you
have to use that PTR record trick for your reverse records, Webmin will
not automatically update them..<br /><br />=A0- Jamie<br /><br />On 9/Dec/2006

Re: [webmin-l] Cluster DNS</div>
<div><br /></div>Hi Grant,<br />You need to click the Apply Changes button
at the bottom of the main page in the BIND module after adding zone.
In a cluster setup, this will restart both the master and slave
servers, and so should trigger the transfer of both forward and
reverse zones..<br /><br />=A0- Jamie<br /><br />On 9/Dec/2006 06:25 Grant
