Hi Grant,<br />I'm not sure what you mean by having an in-addr.arpa entry added when create a new forward zone?<br />Webmin doesn't do anything like this ... instead, it only adds in-addr.arpa PTR records when you create a new forward A record.<br /><br />=A0- Jamie<br /><br />On 11/Dec/2006 07:53 Grant Peel wrote ..

<div><br /></div>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

Re: [webmin-l] Cluster DNS</div>
<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-

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

forward and reverse zones..<br /><br />=A0- Jamie<br /><br />On
