9**Preparation**
10
11Note: The examples provided below use hardcoded paths (here to: _/home/jagger/_). These will have to be modified, so they reflect your actual build environment.
12
131. Compile honggfuzz
142. Download and unpack bind-9.11.\*.tgz
153. Patch ISC BIND
16 ```
17$ cd bind-9.11.1-P3
18$ patch -p1 < honggfuzz/examples/bind/patch-bind-9.11.1-P3
19 ```
20
214. Configure, compile and install ISC BIND
22
23* edit _compile.sh_, so it contains correct dist path
24 ```
25$ ./compile.sh
26$ make install
27 ```
28
295. Copy the custom configuration files to ```/home/jagger/fuzz/bind/dist/etc/named.conf``` (i.e. to your bind/named dist directory)
30
31```
32$ cp honggfuzz/examples/bind/named.conf /home/jagger/fuzz/bind/dist/etc/
33$ cp honggfuzz/examples/bind/test.zone /home/jagger/fuzz/bind/dist/etc/
34 ```
35
366. **Go**
37
38```
39$ honggfuzz/honggfuzz -f IN.req-response/ -z -P -- ./dist/sbin/named -c /home/jagger/fuzz/bind/dist/etc/named.conf -g
