6 nx_server_r - nx_server user role - Security Enhanced Linux Policy

10 SELinux supports Roles Based Access Control (RBAC), some Linux roles
11 are login roles, while other roles need to be transition into.
12 Note: Examples in this man page will use the staff_u SELinux user.
14 Non login roles are usually used for administrative tasks. For example,
16 tasks that require root privileges. Roles control which types a user
17 can run processes with. Roles often have default types assigned to
18 them.
19 The default type for the nx_server_r role is nx_server_t.
21 The newrole program to transition directly to this role.
23 newrole -r nx_server_r -t nx_server_t
25 sudo is the preferred method to do transition from one role to another.
27 You setup sudo to transition to nx_server_r by adding a similar line to
28 the /etc/sudoers file.
29 USERNAME ALL=(ALL) ROLE=nx_server_r TYPE=nx_server_t COMMAND
31 sudo will run COMMAND as staff_u:nx_server_r:nx_server_t:LEVEL
33 When using a a non login role, you need to setup SELinux so that your
35 SELinux user can reach nx_server_r role.
36 Execute the following to see all of the assigned SELinux roles:
38 semanage user -l
40 You need to add nx_server_r to the staff_u user. You could setup the
42 staff_u user to be able to use the nx_server_r role with a command
43 like:
44 $ semanage user -m -R 'staff_r system_r nx_server_r' staff_u
46
50 SELinux policy is customizable based on least access required.
51 nx_server policy is extremely flexible and has several booleans that
52 allow you to manipulate the policy and run nx_server with the tightest
53 access possible.
54 If you want to allow all domains to execute in fips_mode, you must turn
58 on the fips_mode boolean. Enabled by default.
59 setsebool -P fips_mode 1

65 The SELinux process type nx_server_t can manage files labeled with the
66 following file types. The paths listed are the default paths for these
67 file types. Note the processes UID still need to have DAC permissions.

108 semanage fcontext can also be used to manipulate default file context
109 mappings.
110 semanage permissive can also be used to manipulate whether or not a
112 process type is permissive.
113 semanage module can also be used to enable/disable/install/remove pol‐
115 icy modules.
116 semanage boolean can also be used to manipulate the booleans
118 system-config-selinux is a GUI tool available to customize SELinux pol‐
121 icy settings.
