<p class=MsoNormal>Hello all,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><span lang=EN-US>We are successfully using powerdns since some
years as secondary name server on a Debian Server, Version 2.9.17 .<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>It has done a great job so far. However recently
a problem occurred when our master dns server was updated. Since this update,
our master dns server is sending so called glue records along with dns zone
transfers.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>To explain the problem I will use the
following sample values: <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>ns.nameserver.com = Nameservername for my
zone<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>somedomain.com = My dns zone I want to
transfer to pdns from the master<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>PowerDNS blocks the zone transfer with the
following reason: <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>May 09 14:13:10 Domain somedomain.com is
stale, master serial 2007050913, our serial 2007050911<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>May 09 14:13:10 AXFR started for ' somedomain.com',
transaction started<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>May 09 14:13:10 Remote 172.16.0.164 sneaked
in out-of-zone data 'ns.nameserver.com' during AXFR of zone ' somedomain.com'<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>I have been in contact with the vendor of
our primary DNS Server, and we came to the result that powerdns may not support
</span><span lang=EN-US style='font-size:10.0pt;font-family:"Verdana","sans-serif"'>glue
records in DNS zone transfer. </span><span lang=EN-US><o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>So my question to the mailing list is, are
there any chances to get this problem fixed? I understand that this behavior is
wanted to prevent dns injection, but A records for DNS Server records should be
allowed, or maybe an option be added to allow it. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Currently we rolled back the update on our
master dns server, but we can’t leave it in this state forever. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>--<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Thank you and best regards,<o:p></o:p></span></p>
