158 Issue the following commands to run the complete suite of tests.
159 First, as the <systemitem class="username">root</systemitem> user, set up
160 some test interfaces:
161 </para>
162
163 <note>
164 <para>
165 If IPv6 is not enabled in the kernel, there will be several
166 error messages: "RTNETLINK answers: Operation not permitted". These
167 messages do not affect the tests.

175 The test suite may indicate some skipped tests depending on
176 what configuration options are used. Some tests are marked
177 <quote>UNTESTED</quote> if <xref linkend="perl-net-dns"/> is not
178 installed. One test, <quote>CPU</quote>, is known to fail.
179 To run the tests, as an unprivileged user, execute:
180 </para>
181
182<screen remap="test"><userinput>make -k check</userinput></screen>
183
184 <para>

231
232 <para>

534 Test out the new <application>BIND</application> 9 installation.
535 First query the local host address with <command>dig</command>:

537
538<screen><userinput>dig -x 127.0.0.1</userinput></screen>
539
540 <para>
541 Now try an external name lookup, taking note of the speed
542 difference in repeated lookups due to the caching. Run the
543 <command>dig</command> command twice on the same address:

550 You can see almost instantaneous results with the named caching
551 lookups. Consult the <application>BIND</application> Administrator
