6 yppasswdd_selinux - Security Enhanced Linux Policy for the yppasswdd
7 processes
8
10 Security-Enhanced Linux secures the yppasswdd processes via flexible
11 mandatory access control.
12 The yppasswdd processes execute with the yppasswdd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep yppasswdd_t
20
24 The yppasswdd_t SELinux type can be entered via the yppasswdd_exec_t
25 file type.
26 The default entrypoint paths for the yppasswdd_t domain are the follow‐
28 ing:
29 /usr/sbin/rpc.yppasswdd, /usr/sbin/rpc.yppasswdd.env
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 yppasswdd policy is very flexible allowing users to setup their yppass‐
40 wdd processes in as secure a method as possible.
41 The following process types are defined for yppasswdd:
43 yppasswdd_t
45 Note: semanage permissive -a yppasswdd_t can be used to make the
47 process type yppasswdd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. yppass‐
54 wdd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run yppasswdd with the tightest access
56 possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type yppasswdd_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

144 SELinux requires files to have an extended attribute to define the file
145 type.
146 You can see the context of a file using the -Z option to ls
148 Policy governs the access confined processes have to these files.
150 SELinux yppasswdd policy is very flexible allowing users to setup their
151 yppasswdd processes in as secure a method as possible.
152 STANDARD FILE CONTEXT
154 SELinux defines the file context types for the yppasswdd, if you wanted
156 to store files with these types in a diffent paths, you need to execute
157 the semanage command to sepecify alternate labeling and then use
158 restorecon to put the labels on disk.
159 semanage fcontext -a -t yppasswdd_var_run_t '/srv/myyppasswdd_con‐
161 tent(/.*)?'
162 restorecon -R -v /srv/myyppasswdd_content
163 Note: SELinux often uses regular expressions to specify labels that
165 match multiple files.
166 The following file types are defined for yppasswdd:
168 yppasswdd_exec_t
172 - Set files with the yppasswdd_exec_t type, if you want to transition
174 an executable to the yppasswdd_t domain.
175 Paths:
178 /usr/sbin/rpc.yppasswdd, /usr/sbin/rpc.yppasswdd.env
179 yppasswdd_var_run_t
182 - Set files with the yppasswdd_var_run_t type, if you want to store the
184 yppasswdd files under the /run or /var/run directory.
185 Note: File context can be temporarily modified with the chcon command.
189 If you want to permanently change the file context you need to use the
190 semanage fcontext command. This will modify the SELinux labeling data‐
191 base. You will need to use restorecon to apply the labels.
192
195 semanage fcontext can also be used to manipulate default file context
196 mappings.
197 semanage permissive can also be used to manipulate whether or not a
199 process type is permissive.
200 semanage module can also be used to enable/disable/install/remove pol‐
202 icy modules.
203 semanage boolean can also be used to manipulate the booleans
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
208 icy settings.
