<p style="margin-left:11%; margin-top: 1em">nx_server_r
− <b>nx_server user role</b> - Security Enhanced Linux
Policy</p>
<h2>DESCRIPTION
<a name="DESCRIPTION"></a>
</h2>
<p style="margin-left:11%; margin-top: 1em">SELinux
supports Roles Based Access Control (RBAC), some Linux roles
are login roles, while other roles need to be transition
into.</p>
<p style="margin-left:11%; margin-top: 1em"><i>Note:</i>
Examples in this man page will use the <b>staff_u</b>
SELinux user.</p>
<p style="margin-left:11%; margin-top: 1em">Non login roles
are usually used for administrative tasks. For example,
tasks that require root privileges. Roles control which
types a user can run processes with. Roles often have
default types assigned to them.</p>
<p style="margin-left:11%; margin-top: 1em">The default
type for the nx_server_r role is nx_server_t.</p>
<p style="margin-left:11%; margin-top: 1em">The
<b>newrole</b> program to transition directly to this
role.</p>
<p style="margin-left:11%; margin-top: 1em"><b>newrole -r
nx_server_r -t nx_server_t</b></p>
<p style="margin-left:11%; margin-top: 1em"><b>sudo</b> is
the preferred method to do transition from one role to
another. You setup sudo to transition to nx_server_r by
adding a similar line to the /etc/sudoers file.</p>
<p style="margin-left:11%; margin-top: 1em">USERNAME
ALL=(ALL) ROLE=nx_server_r TYPE=nx_server_t COMMAND</p>
<p style="margin-left:11%; margin-top: 1em">sudo will run
COMMAND as staff_u:nx_server_r:nx_server_t:LEVEL</p>
<p style="margin-left:11%; margin-top: 1em">When using a a
non login role, you need to setup SELinux so that your
SELinux user can reach nx_server_r role.</p>
<p style="margin-left:11%; margin-top: 1em">Execute the
following to see all of the assigned SELinux roles:</p>
<p style="margin-left:11%; margin-top: 1em"><b>semanage
user -l</b></p>
<p style="margin-left:11%; margin-top: 1em">You need to add
nx_server_r to the staff_u user. You could setup the staff_u
user to be able to use the nx_server_r role with a command
like:</p>
<p style="margin-left:11%; margin-top: 1em"><b>$ semanage
user -m -R ’staff_r system_r nx_server_r’
staff_u</b></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. nx_server
policy is extremely flexible and has several booleans that
allow you to manipulate the policy and run nx_server with
the tightest access possible.</p>
<p style="margin-left:11%; margin-top: 1em">If you want to
deny any process from ptracing or debugging any other
processes, you must turn on the deny_ptrace boolean. Enabled
by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
deny_ptrace 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow any process to mmap any file on system with attribute
file_type, you must turn on the domain_can_mmap_files
boolean. Enabled by default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_can_mmap_files 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains write to kmsg_device, while kernel is
executed with systemd.log_target=kmsg parameter, you must
turn on the domain_can_write_kmsg boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_can_write_kmsg 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains to use other domains file descriptors, you
must turn on the domain_fd_use boolean. Enabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_fd_use 1</b></p>
<p style="margin-left:11%; margin-top: 1em">If you want to
allow all domains to have the kernel load modules, you must
turn on the domain_kernel_load_modules boolean. Disabled by
default.</p>
<p style="margin-left:11%; margin-top: 1em"><b>setsebool -P
domain_kernel_load_modules 1</b></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
enable reading of urandom for all domains, you must turn on
the global_ssp boolean. Disabled by default.</p>
