<h2>NAME
<a name="NAME"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">fdo_ssh_selinux
− Security Enhanced Linux Policy for the fdo_ssh
processes</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">Security-Enhanced
Linux secures the fdo_ssh processes via flexible mandatory
access control.</p>
<p style="margin-left:11%; margin-top: 1em">The fdo_ssh
processes execute with the fdo_ssh_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 fdo_ssh_t</b></p>
<h2>ENTRYPOINTS
<a name="ENTRYPOINTS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The fdo_ssh_t
SELinux type can be entered via the <b>ssh_exec_t</b> file
type.</p>
<p style="margin-left:11%; margin-top: 1em">The default
entrypoint paths for the fdo_ssh_t domain are the
following:</p>
<p style="margin-left:11%; margin-top: 1em">/usr/bin/ssh,
/usr/libexec/nm-ssh-service</p>
<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 fdo_ssh
policy is very flexible allowing users to setup their
fdo_ssh processes in as secure a method as possible.</p>
<p style="margin-left:11%; margin-top: 1em">The following
process types are defined for fdo_ssh:</p>
<p style="margin-left:11%; margin-top: 1em"><b>fdo_ssh_t</b></p>
<p style="margin-left:11%; margin-top: 1em">Note:
<b>semanage permissive -a fdo_ssh_t</b> can be used to make
the process type fdo_ssh_t permissive. SELinux does not deny
access to permissive process types, but the AVC (SELinux
denials) messages are still generated.</p>
<h2>BOOLEANS
<a name="BOOLEANS"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux policy
is customizable based on least access required. fdo_ssh
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run fdo_ssh with the
tightest access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains to execute in fips_mode, you must turn on
the fips_mode boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
fips_mode 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow system to run with NIS, you must turn on the
nis_enabled boolean. Disabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
nis_enabled 1</b></p>
<h2>MANAGED FILES
<a name="MANAGED FILES"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">The SELinux
process type fdo_ssh_t can manage files labeled with the
following file types. The paths listed are the default paths
for these file types. Note the processes UID still need to
have DAC permissions.</p>
<p style="margin-left:11%; margin-top: 1em"><b>krb5_host_rcache_t</b></p>
