Hello,
One of my users, from whom I take an AXFR, has been experimenting
with DNS Service Discovery (http://www.dns-sd.org/).
Into his BIND zone file he put the following:
$ORIGIN _tcp.atomic-x.co.uk.
_autodiscover SRV 0 0 443 atomic-x.co.uk.
_http PTR atomic-x\.co\.uk\032Webmail._http
PTR atomic-x\.co\.uk\032Homepage._http
and on one of my BIND slaves, it appears the same as above. My PDNS
servers (using sqlite) took an AXFR of this and ended up storing the
following in the DB:
sqlite> select * from records where domain_id=70 and type="PTR";
180258|70|_http._tcp.atomic-x.co.uk|PTR|atomic-x\\.co\\.uk\\
Webmail._http._tcp.atomic-x.co.uk.|1800|0|
180259|70|_http._tcp.atomic-x.co.uk|PTR|atomic-x\\.co\\.uk\\
Homepage._http._tcp.atomic-x.co.uk.|1800|0|
180264|70|b._dns-sd._udp.atomic-x.co.uk|PTR|atomic-x.co.uk.|1800|0|
180265|70|lb._dns-sd._udp.atomic-x.co.uk|PTR|atomic-x.co.uk.|1800|0|
The backslash-escaped space there does not look correct.
When I query a bind9 server, I get the expected response:
$ dig +noall +answer -t ptr _http._tcp.atomic-x.co.uk @a.authns.bitfolk.com.
_http._tcp.atomic-x.co.uk. 1800 IN PTR
atomic-x\.co\.uk\032Homepage._http._tcp.atomic-x.co.uk.
_http._tcp.atomic-x.co.uk. 1800 IN PTR
atomic-x\.co\.uk\032Webmail._http._tcp.atomic-x.co.uk.
The same towards one of the PDNS servers:
$ dig +noall +answer -t ptr _http._tcp.atomic-x.co.uk @b.authns.bitfolk.com.
_http._tcp.atomic-x.co.uk. 1800 IN PTR atomic-x\.co\.uk\\\000.
_http._tcp.atomic-x.co.uk. 1800 IN PTR atomic-x\.co\.uk\\\000.
Is this a bug? Any workaround here?
pdns-backend-sqlite / pdns-server 2.9.21.2-1, Debian Lenny.
Cheers,
Andy
