+
+<h2><a name="overview">Overview</a></h2>
+
+<p><tt>nss-myhostname</tt> is a plugin for the GNU Name Service Switch
+(NSS) functionality of the GNU C Library (<tt>glibc</tt>) providing
+host name resolution for the locally configured system hostname as
+returned by <tt>gethostname(2)</tt>. Various software relies on an
+always resolvable local host name. When using dynamic hostnames this
+is usually achieved by patching <tt>/etc/hosts</tt> at the same time
+as changing the host name. This however is not ideal since it requires
+a writable <tt>/etc</tt> file system and is fragile because the file
+might be edited by the administrator at the same
+time. <tt>nss-myhostname</tt> simply returns all locally configure
+public IP addresses, or -- if none are configured -- the IPv4
+address <tt>127.0.0.2</tt> (wich is on the local loopback) and the
+IPv6 address <tt>::1</tt> (which is the local host) for whatever
+system hostname is configured locally. Patching <tt>/etc/hosts</tt>
+is thus no longer necessary.</p>
+
+<h2><a name="status">Current Status</a></h2>
+
+<p>It works!</p>
+
+<h2><a name="documentation">Documentation</a></h2>
+
+<p>After compiling and installing <tt>nss-myhostname</tt> you'll find a
+new NSS modules in <tt>/lib</tt>:</p>
+<ul>
+<li><tt>libnss_myhostname.so.2</tt></li>
+</ul>
+
+<p>To activate the NSS modules you have to edit
+<tt>/etc/nsswitch.conf</tt> and add <tt>myhostname</tt> to the
+line starting with "<tt>hosts:</tt>". On Debian this looks like
+this:</p>
+
+<pre># /etc/nsswitch.conf
+
+passwd:         compat
+group:          compat
+shadow:         compat
+
+hosts:          files dns <b>myhostname</b>
+networks:       files
+
+protocols:      db files
+services:       db files
+ethers:         db files
+rpc:            db files
+
+netgroup:       nis</pre>
+
+<p>That's it. You should now always be able to resolve your local
+system hostname. For a quick check
+use <tt>glibc</tt>'s <tt>getent</tt> tool:
+
+<pre>$ getent ahosts `hostname`
+::1             STREAM omega
+::1             DGRAM
+::1             RAW
+127.0.0.2       STREAM
+127.0.0.2       DGRAM
+127.0.0.2       RAW
+</pre>
+
+<p>In this case the local host name is <i>omega</i>.</p>
+
+<p>It is recommended to put <tt>myhostname</tt> last in
+the <tt>nsswitch.conf</tt> line to make sure that this mapping is only
+used as fallback, and any DNS or <tt>/etc/hosts</tt> based mapping takes
+precedence.</p>
+
+<h2><a name="requirements">Requirements</a></h2>
+
+<p><tt>nss-myhostname</tt> uses NSS interfaces that are specific to modern <tt>glibc</tt>'s.</p>
+
+<p><tt>nss-myhostname</tt> was developed and tested on Fedora 15 from
+May 2011, it should work on most other Linux distributions since it
+uses GNU autoconf and GNU libtool for source code configuration and
+shared library management.</p>
+
+<h2><a name="installation">Installation</a></h2>
+
+<p>As this package is made with the GNU autotools you should run
+<tt>./configure</tt> inside the distribution directory for configuring
+the source tree. After that you should run <tt>make</tt> for
+compilation and <tt>make install</tt> (as root) for installation of
+<tt>nss-myhostname</tt>.</p>
+
+<h2><a name="acks">Acknowledgements</a></h2>
+
