COMPILING
---------
+$ ./configure
+$ make or gmake
+
The only dependency is Boost, http://boost.org/
You only need to download it, there is no need to compile.
3) Compile the PowerDNS recursor using:
-$ CXXFLAGS=-I./boost_1_33_1/ make
+$ CXXFLAGS=-I./boost_1_33_1/ ./configure
+$ CXXFLAGS=-I./boost_1_33_1/ make clean
+$ CXXFLAGS=-I./boost_1_33_1/ make all
+(the 'clean' is needed to have make pick up the new boost)
4) Run ./pdns_recursor and you should be set!
+5) (g)make install
+
PERFORMANCE
-----------
------------------------------
To prevent hassles with g++ 4.1 dependencies, you can build like this:
$ STATIC=semi make all
-or even
- $ STATIC=full make all

+ <itemizedlist>
+ <listitem>
<para>
- Verisign backed off, this feature is no longer needed (for now).
+ Limit the size of the cache to a sensible value. Cache hit rate does not improve meaningfully beyond 4 million <command>max-cache-entries</command>,
+ reducing the memory footprint reduces CPU cache misses.
</para>
- </note>
- </para>
- <para>
- Verisign, the current operator of the COM and NET zones, decided to add a wildcard record so as to draw all queries for non-existing
- domains to their own page, which lists domains you might want to visist instead.
- </para>
- <para>
- To reinstate old behaviour, add <command>delegation-only=com,net</command> to your recursor configuration.
- </para>
- <para>
- What this does is reject all authoritative answers from the COM and NET servers. ISC, the current maintainers of BIND, have
- implemented this feature first, PowerDNS has mostly copied their algorithm. Thanks!
- </para>
- <para>
- Verisign might decide to evade our tactic with wildcard NS records, by which time other measures will be needed to restore the
- old behaviour.
