6 mrtg_selinux - Security Enhanced Linux Policy for the mrtg processes
7
9 Security-Enhanced Linux secures the mrtg processes via flexible manda‐
10 tory access control.
11 The mrtg processes execute with the mrtg_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep mrtg_t
19
23 The mrtg_t SELinux type can be entered via the mrtg_exec_t file type.
24 The default entrypoint paths for the mrtg_t domain are the following:
26 /usr/bin/mrtg
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 mrtg policy is very flexible allowing users to setup their mrtg pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for mrtg:
40 mrtg_t
42 Note: semanage permissive -a mrtg_t can be used to make the process
44 type mrtg_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. mrtg
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run mrtg with the tightest access possible.
53 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
71 The SELinux process type mrtg_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

114 SELinux requires files to have an extended attribute to define the file
115 type.
116 You can see the context of a file using the -Z option to ls
118 Policy governs the access confined processes have to these files.
120 SELinux mrtg policy is very flexible allowing users to setup their mrtg
121 processes in as secure a method as possible.
122 EQUIVALENCE DIRECTORIES
124 mrtg policy stores data with multiple different file context types
127 under the /var/lock/mrtg directory. If you would like to store the
128 data in a different directory you can use the semanage command to cre‐
129 ate an equivalence mapping. If you wanted to store this data under the
130 /srv directory you would execute the following command:
131 semanage fcontext -a -e /var/lock/mrtg /srv/mrtg
133 restorecon -R -v /srv/mrtg
134 STANDARD FILE CONTEXT
136 SELinux defines the file context types for the mrtg, if you wanted to
138 store files with these types in a diffent paths, you need to execute
139 the semanage command to sepecify alternate labeling and then use
140 restorecon to put the labels on disk.
141 semanage fcontext -a -t mrtg_var_run_t '/srv/mymrtg_content(/.*)?'
143 restorecon -R -v /srv/mymrtg_content
144 Note: SELinux often uses regular expressions to specify labels that
146 match multiple files.
147 The following file types are defined for mrtg:
149 mrtg_etc_t
153 - Set files with the mrtg_etc_t type, if you want to store mrtg files
155 in the /etc directories.
156 mrtg_exec_t
160 - Set files with the mrtg_exec_t type, if you want to transition an
162 executable to the mrtg_t domain.
163 mrtg_initrc_exec_t
167 - Set files with the mrtg_initrc_exec_t type, if you want to transition
169 an executable to the mrtg_initrc_t domain.
170 mrtg_lock_t
174 - Set files with the mrtg_lock_t type, if you want to treat the files
176 as mrtg lock data, stored under the /var/lock directory
177 Paths:
180 /var/lock/mrtg(/.*)?, /var/lock/mrtg-rrd(/.*)?, /etc/mrtg/mrtg.ok,
181 /var/lock/subsys/mrtg
182 mrtg_log_t
185 - Set files with the mrtg_log_t type, if you want to treat the data as
187 mrtg log data, usually stored under the /var/log directory.
188 mrtg_var_lib_t
192 - Set files with the mrtg_var_lib_t type, if you want to store the mrtg
194 files under the /var/lib directory.
195 mrtg_var_run_t
199 - Set files with the mrtg_var_run_t type, if you want to store the mrtg
201 files under the /run or /var/run directory.
202 Note: File context can be temporarily modified with the chcon command.
206 If you want to permanently change the file context you need to use the
207 semanage fcontext command. This will modify the SELinux labeling data‐
208 base. You will need to use restorecon to apply the labels.
209
212 semanage fcontext can also be used to manipulate default file context
213 mappings.
214 semanage permissive can also be used to manipulate whether or not a
216 process type is permissive.
217 semanage module can also be used to enable/disable/install/remove pol‐
219 icy modules.
220 semanage boolean can also be used to manipulate the booleans
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
225 icy settings.
