Re: Re: net::dns::update and in-addr.arpa ??

[Anonymous Monk]

Hi, thanks so far - but i think I have to explain my problem in more detail:
I use the examples from net::dns::update. Adding or deleting A records works great!
But there are no examples how to write PTR records to in-addr.arpa zones.
i have tried syntax like those from "nsupdate" :
update: {add} 13.13.168.192.in-addr.arpa. 86400 IN PTR testhost.foo.com.
but with no success ! (NOTZONE RETURN CODE from DNS-Server)

here is my example without variables:

.
my $update = Net::DNS::Update->new(foo.com);
$update->push("pre", nxrrset("3.13.168.192.in-addr.arpa. PTR testhost.
+foo.com."));
$update->push("update", rr_add("$3.13.168.192.in-addr.arpa. 86400 IN P
+TR testhost.foo.com."));

my $res = Net::DNS::Resolver->new;
$res->nameservers(nameserver.foo.com);
my $reply = $res->send($update);
.

answers to the questions:
as far as i know there shold be a "dot" after the domain name (testhost.foo.com.)
Net::DNS::Update->new should refer to den DNS domain
there are no right problems...

I now believe that the issue is what I mentioned, you are not updating foo.com; you are updating in-addr.arpa. Try making that the arg to new. Also I presume the $ before the IP is a typo?

10 years later and I have this exact same problem. Can't figure out how to add a PTR record using Net::DNS. I wonder if OP ever figured this out...

The syntax of my rr_add is: rr_add(X.XXX.XXX.XX.in-addr.arpa 3600 PTR hostname.mydomain.com.)

Is this correct? Thanks in advance...

   # Create the update packet:
   my $update = Net::DNS::Update->new($OURDOMAIN);

   #  Add the PTR record:
   $update->push(update => rr_add("$rev 3600 PTR $hst"));

   # Send the update to the zone's primary master.
   my $res = Net::DNS::Resolver->new;
   $res->nameservers("$OURNMSERV");

   my $reply = $res->send($update);

Resolved. Do a 'dig -x' on a valid IP address on the network. The "AUTHORITY SECTION" shows the in-addr.arpa zone to use for the 'new Net::DNS::Update' parameter.
