<title>Installation of <application>vsFTPD</application></title>

<para>For security reasons, running 
<application>vs<acronym>FTP</acronym>D</application> as an unprivileged user 
and group is encouraged. Also, a user to map anonymous users to should be
created.</para>

<screen><userinput><command>install -d -m 0755 /var/ftp/empty &amp;&amp;
install -d -m 0755 /home/ftp &amp;&amp;
groupadd vsftpd &amp;&amp;
useradd -d /dev/null -c "vsFTPD User" -g vsftpd -s /bin/false vsftpd &amp;&amp;
groupadd ftp &amp;&amp;
useradd -c anonymous_user -d /home/ftp -g ftp -s /bin/false ftp</command>
</userinput></screen>

<para>Install <application>vs<acronym>FTP</acronym>D</application> by running 
the following commands:</para>

<screen><userinput><command>make &amp;&amp;
install -m 755 vsftpd /usr/sbin/vsftpd &amp;&amp;
install -m 644 vsftpd.8 /usr/share/man/man8 &amp;&amp;
install -m 644 vsftpd.conf.5 /usr/share/man/man5 &amp;&amp;
install -m 644 vsftpd.conf /etc</command></userinput></screen>

<title>Command explanations</title>

<para><parameter>install -d [...]</parameter>: This creates the directory that
anonymous users will use (<filename class='directory'>/home/ftp</filename>) 
and the directory the daemon will chroot into 
(<filename class='directory'>/var/ftp/empty</filename>).</para>

<note><para><filename class="directory">/home/ftp</filename> should not be
owned by the user vsftpd, or the user ftp.</para></note>

<para><parameter>echo "#define VSF_BUILD_TCPWRAPPERS" >>builddefs.h</parameter>:
Use this prior to <command>make</command> to add support for 
<application>tcpwrappers</application>.</para>

<para><parameter>echo "#define VSF_BUILD_SSL" >>builddefs.h</parameter>:
Use this prior to <command>make</command> to add support for 
<acronym>SSL</acronym>.</para>

<para><parameter>install -m [...]</parameter>:
The <filename>Makefile</filename> hardwires 
<filename class='directory'>/usr/local</filename> (if it exists). These 
commands install the files in 
<filename class='directory'>/usr</filename>.</para>

<title>Configuring <application>vs<acronym>FTP</acronym>D</application></title>

<para>Install the <filename>/etc/rc.d/init.d/vsftpd</filename>
init script included in the

<para><filename>/etc/vsftpd.conf</filename></para>
</sect3>

<sect3><title>Configuration information</title>
<para><application>vs<acronym>FTP</acronym>D</application> comes with a basic 
anonymous-only configuration file that was copied to 
<filename class='directory'>/etc</filename> above. This file should be modified 
because it is now recommended to run <command>vsftpd</command> in standalone 
mode as opposed to <command>inetd</command>/<command>xinetd</command> mode. 
Also, you should specify the privilege separation user created above. Finally, 
you should specify the <command>chroot</command> directory. 
<command>man vsftpd.conf</command> will give you all the details.</para>

<screen><userinput><command>cat &gt;&gt; /etc/vsftpd.conf &lt;&lt; "EOF"</command>
background=YES
listen=YES
nopriv_user=vsftpd
