[Pdns-users] pdns as a resolver

[Jan Gyselinck]

Hi,

I'm currently looking at pdns as a resolver to see how good
and performant it is.  However, I didn't get very far.

The compilation of the recursor failed with this error:

g++ -DHAVE_CONFIG_H -I. -I. -I..   -Ibackends/bind
-DSYSCONFDIR=\"/prod/pdns/etc\" -DLIBDIR=\"/prod/pdns/lib\"
-DLOCALSTATEDIR=\"/var/run\" -Ibackends/bind -D_REENTRANT -mcpu=v9

   EventVal>::makeThread(void (*)(void*), void*) [with EventKey = PacketID,

(compiled with gcc 3.3 on Solaris 8)

My knowledge of c++ is very limited so I didn't see how I could fix
this.  I reran configure, disabled the recursor, and the compile worked.

So then I wondered what pdns would give for performance if I used
with BIND 8 as a backend recursor.  But then I hit another wall,
apparently.  Pdns seems to refuse to answer to my queries, but I
do see it querying my BIND resolver, I do see it answering, but
then I see this in the logs:

How do I fix this, am I doing something wrong?
