<title>Installation of <application>ProFTPD</application></title>

<para>For security reasons, running <application>ProFTPD</application>
as an unprivileged user and group is encouraged.</para>

<screen><userinput><command>groupadd proftpd &amp;&amp;
useradd -c proftpd -d /home/ftp -g proftpd -s /bin/false proftpd</command>
</userinput></screen>

<para>Install <application>ProFTPD</application> by running the following commands:</para>

<title>Command explanations</title>

<para><parameter>install_user=proftpd install_group=proftpd</parameter>:
Specify the user and group identity for ProFTPD.</para>

<para><parameter>--sysconfdir=/etc</parameter>:
This prevents the configuration files from going to
<filename class="directory">/usr/etc</filename>.</para>

<para><parameter>--localstatedir=/var/run</parameter>:
This uses <filename class="directory">/var/run</filename> instead of
<filename class="directory">/usr/var</filename> for lock files.</para>
