− Security Enhanced Linux Policy for the ftpd
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the ftpd processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The ftpd
processes execute with the ftpd_t SELinux type. You can
check if you have these processes running by executing the
<b>ps</b> command with the <b>−Z</b> qualifier.</p>
<p style="margin-left:11%; margin-top: 1em">For
example:</p>
<p style="margin-left:11%; margin-top: 1em"><b>ps -eZ |
grep ftpd_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The ftpd_t
SELinux type can be entered via the <b>ftpd_exec_t</b> file
type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the ftpd_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/sbin/ftpwho,
/usr/sbin/vsftpd, /usr/sbin/in.ftpd, /usr/sbin/proftpd,
/usr/sbin/muddleftpd, /usr/kerberos/sbin/ftpd,

<h2>PROCESS TYPES
<a name="PROCESS TYPES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux defines
process types (domains) for each process running on the
system</p>
<p style="margin-left:11%; margin-top: 1em">You can see the
context of a process using the <b>−Z</b> option to
<b>ps</b></p>
<p style="margin-left:11%; margin-top: 1em">Policy governs
the access confined processes have to files. SELinux ftpd
policy is very flexible allowing users to setup their ftpd
processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for ftpd:</p>
<p style="margin-left:11%; margin-top: 1em"><b>ftpd_t,
ftpdctl_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a ftpd_t</b> can be used to make the
process type ftpd_t permissive. SELinux does not deny access
to permissive process types, but the AVC (SELinux denials)
messages are still generated.</p>
<h2>BOOLEANS

</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux policy
is customizable based on least access required. ftpd policy
is extremely flexible and has several booleans that allow
you to manipulate the policy and run ftpd with the tightest
access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
determine whether ftpd can connect to all unreserved ports,
