Hi Bert,
I have a few that we've put on a bind server locally here. We were
providing secondary service for one domain that had WKS records (which
is how I ended up starting down this road).
Here are the WKS records that customer's nameserver was spitting out
towards us.
atlantica.us. 604800 IN WKS 173.16.9.10 6 22 25 42 53 80
113 443 6667 8008
atlantica.us. 604800 IN WKS 173.16.9.10 17 22 25 42 53 80
443 8008
*.atlantica.us. 604800 IN WKS 173.16.9.10 6 22 25 42 53 80 113 443 6667
8008
*.atlantica.us. 604800 IN WKS 173.16.9.10 17 22 25 42 53 80
443 8008
Ariel.atlantica.us. 604800 IN WKS 173.16.9.10 6 22 25 42 80 113 443 6667
8008
Ariel.atlantica.us. 604800 IN WKS 173.16.9.10 17 22 25 42 80 443
8008
It seems shorter versions of the WKS record will go in, but they cause
other issues. (see below)
For example: This record will actually work, and be entered into the
database without crashing the backend.

Garry,
"2.6.1 WKS WKS records are deprecated in [RFC 1123]. They serve no known
useful function, except internally among LISP machines"
Normally we'd whip up an implementation just to have the issue go away, but
it is a pretty weird record type too, containing a bitmap of protocols.
Unknown record type support might save us, but it is not quite there yet it
appears.
I struggle to find some WKS zone file examples btw, do you have any?

Hi Ken,
I just found your ticket from abut 4 years ago... Seems strange that
it's still a bug. We just ran a few tests and yep.. you were
completely correct, WKS records just piss off pdns something fierce.
I'll consolidate the test case down to something reasonable and
submit a bug report.

Ah, I hit the same problem. WKS records are not supported by
PDNS. On top of that, they are not really useful and have not
been for quite a while. Try nuking them and your zone should
transfer fine.

Simply removing the zone puts everything back in a happy state, so It's
not
a timeout issue. Are there any debugging options that can be turned on
for
the mysql backend? I didn't find any referenced in the documentation and
increasing the loglevel doesn't give me any additional information.
I've pulled down the zone and besides the laundry list of different
record
types, it looks fine. I can sanitize it an post it if that would help.
The pdns version is the static .deb package from the main download page.
Any help is appreciated.
Thanks,
Gary
Hi Gary,
Try enabling the MySQL query logging to see what command is being
received by the backend. You can also bump the logging level on the
PDNS system to see if it gives you more information. Have you changed
any of the default queries? What is your PDNS configuration, including
the backend chosen? At 27 entries, you could post the entire zone but
if the problem is a weird character, sanitizing it will make the
information useless. I would try bumping the debugging levels first.
I cannot help much on the MySQL side since we use PostgreSQL as the
backend database.
I already tried both of those. Increasing the loglevel didn't yield any
additional information and query log didn't include the query, I suspect
due to it's failure.
I've attached the zone. I've changed the hostnames and ip's. The remainder
of the zone is untouched.
Gary
Regards,
Ken
