<title>Installation of Net-tools</title>

<para>If you don't know what to answer to all the questions asked during the
<command>make config</command> phase below, then just accept the defaults.
This will be just fine in the majority of cases. What you're asked here is a
bunch of questions about which network protocols you've enabled in your
kernel. The default answers will enable the tools from this package to work
with the most common protocols: TCP, PPP, and several others. You still need
to actually enable these protocols in the kernel -- what you do here is merely
telling the package to include support for those protocols in its programs,
but it's up to the kernel to make the protocols available.</para>

<para>This package also has issues with being compiled by GCC 3.4, which we
fix by applying the following patch:</para>

<screen><userinput>patch -Np1 -i ../net-tools-&net-tools-version;-gcc34-2.patch</userinput></screen>

<para>Net-tools has issues with the Linux 2.6 kernel series - fix these issues
by applying the following patch:</para>

<screen><userinput>patch -Np1 -i ../net-tools-&net-tools-version;-kernel_headers-1.patch</userinput></screen>

<para>Now prepare Net-tools for compilation (if you intend to accept the
defaults, you can skip all the questions by running <userinput>yes "" |
make config</userinput> instead):</para>

<screen><userinput>make config</userinput></screen>

<para>Compile the package:</para>

<screen><userinput>make</userinput></screen>

<para>Now install it:</para>

<screen><userinput>make update</userinput></screen>
