Re: [Pdns-users] Differing (incorrect) behavior in 2.9.21 for AAAA records versus 2.9.20...
Hello I have this problem too. i try this patch http://wiki.powerdns.com/cgi-bin/trac.fcgi/changeset/1081 I'have download the last SVN 1097 compil and install on a new server, result is always a same. If i ask the server for a type he return the wildcard CNAME even if a A type exist. Is there someone who have resolv this bug.

Well it certainly seems to fix the problem (#125); the other bug that seems related is #124: http://wiki.powerdns.com/cgi-bin/trac.fcgi/ticket/124 This still exists, but I'm not sure this is a problem, I only know it is different then what BIND returns; mostly it probably depends on how the resolvers handle SERVFAILs. -- Augie Schwer-[EMAIL PROTECTED]-http://schwer.us Key fingerprint = 9815 AE19 AFD1 1FE7 5DEE 2AC3 CB99 2784 27B0 C072 ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users

[Pdns-users] Differing (incorrect) behavior in 2.9.21 for AAAA records versus 2.9.20...
In the presence of a *.domain.com CNAME, 2.9.21, when asked for a more specific A record responds appropriately with the A record when an A record exists, and NOERROR/no answer for an MX or whatever. However, when asked for an record, it will respond with the splat/*.domain.com CNAME instead. An example of this is barracuda.neit.edu, ns1.modwest.com is running 2.9.20, and ns2.modwest.com is running 2.9.21, ns2 responds incorrectly directing traffic to the wrong place. Any idea when I can see a fix for this behavior? -- Genius might be described as a supreme capacity for getting its possessors into trouble of all kinds. -- Samuel Butler ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users

Any idea when I can see a fix for this behavior? I submitted a bug on this a while back: http://wiki.powerdns.com/cgi-bin/trac.fcgi/ticket/125 And have been most recently lobbying (annoyingly at this point probably) for a fix, but demand drives change, and there isn't much demand to fix this bug yet. If there was a voting system for bugs, then I think some people would vote for this bug to be fixed, but as it stands maybe the best way to vote for a fix is to put a me too entry on the open ticket; that or fix it yourself, which I think is easier said then done as most likely the bug is in the DB backend code as it seems to be too greedy in what it grabs. -- Augie Schwer-[EMAIL PROTECTED]-http://schwer.us Key fingerprint = 9815 AE19 AFD1 1FE7 5DEE 2AC3 CB99 2784 27B0 C072 ___ Pdns-users mailing list Pdns-users@mailman.powerdns.com http://mailman.powerdns.com/mailman/listinfo/pdns-users

The place to fix this is in the packethandler.cc, and not in the backend. CNAME wildcards are complicated beasts and complicate the packethandler - you could probably tweak that code to do what you want easily enough, but you might then break other things if you don't tread very carefully. I'll have a brief look now, perhaps the fix is easy.

(yes just heh. I haven't looked at teh new backend code at all) In this case, the behaviour differs for matching wildcards versus partially matching wildcards, where the latter is of the right qname, but the wrong qtype. A fix is in svn, so I wonder if people can verify that it solves the problem.
