[Pdns-users] Help with Pipe Backend

[pdns at nodice.us]

Hello everyone. I'm having a problem using the Pipe backend.



What I'm trying to do is have all queries that come in get answered with a
specific ip. To do this, I'm trying out the Pipe backend using a basic
perl script.



pdns.conf (authritative server version 3.3):

launch=pipe

pipe-command=/etc/pdns/example.pl

local-address=127.0.0.1

default-soa-name=billy.com
-----------------------------

perl script:

#!/usr/bin/perl



use warnings;

use strict;



$|=1;Â Â  Â Â Â  Â Â Â  Â Â Â 
     # no buffering



my $line=<>;

chomp($line);



unless($line eq "HELO\t1") {

    print "FAIL\n";

    print STDERR "Received '$line'\n";

    <>;

    exit;

}

print "OKÂ Â  Â Pipe backend firing
up\n";Â Â  Â # print our banner



while(<>)

{

    print STDERR "$$ Received: $_";

    chomp();

    my @arr=split(/\t/);

    if(@arr<6) {

        print "LOG  
 PowerDNS sent unparseable line\n";

        print "FAIL\n";

        next;

    }



    my
($type,$qname,$qclass,$qtype,$id,$ip)=split(/\t/);



    if ($qtype eq "A" || $qtype eq
"ANY") {

        print STDERR "$$ Sent A
records\n";

        print "DATA  
 $qname    $qclass    A  
 3600    -1    192.168.1.69\n";

    }



    print STDERR "$$ End of data\n";

    print "END\n";

}


-----------------------------

pdns monitor:

Aug 16 17:30:48 Remote 127.0.0.1 wants 'billy.com|A', do = 0, bufsize =
512: packetcache MISS

29715 Received: Q    billy.com  
 IN    SOA    -1  
 127.0.0.1

29715 End of data



Looks like it queries for an SOA record first, doesn't find anything and
just returns an empty response. I tried adding default-soa-name in the
conf, but that doesn't seem to work as I anticipated either.



Any help would be appreciated.
Thanks,
Billy
