inetd_selinux(8) inetd SELinux Policy documentation inetd_selinux(8)NAMEinetd_selinux - Security Enhanced Linux Policy for the inetd processes
DESCRIPTION
Security-Enhanced Linux secures the inetd processes via flexible manda‐
tory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the inetd_t,
inetd_child_t, you must turn on the authlogin_nsswitch_use_ldap bool‐
ean.
setsebool -P authlogin_nsswitch_use_ldap 1
If you want to allow confined applications to run with kerberos for the
inetd_t, inetd_child_t, you must turn on the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the inetd_t,
inetd_child_t, you must turn on the allow_ypbind boolean.
setsebool -P allow_ypbind 1
FILE CONTEXTS
SELinux requires files to have an extended attribute to define the file
type.
You can see the context of a file using the -Z option to ls
Policy governs the access confined processes have to these files.
SELinux inetd policy is very flexible allowing users to setup their
inetd processes in as secure a method as possible.
The following file types are defined for inetd:
inetd_child_exec_t
- Set files with the inetd_child_exec_t type, if you want to transition
an executable to the inetd_child_t domain.
Paths:
/usr/sbin/identd, /usr/local/lib/pysieved/pysieved.*.py,
/usr/sbin/in..*d
inetd_child_tmp_t
- Set files with the inetd_child_tmp_t type, if you want to store inetd
child temporary files in the /tmp directories.
inetd_child_var_run_t
- Set files with the inetd_child_var_run_t type, if you want to store
the inetd child files under the /run directory.
inetd_exec_t
- Set files with the inetd_exec_t type, if you want to transition an
executable to the inetd_t domain.
Paths:
/usr/sbin/inetd, /usr/sbin/xinetd, /usr/sbin/rlinetd
inetd_log_t
- Set files with the inetd_log_t type, if you want to treat the data as
inetd log data, usually stored under the /var/log directory.
inetd_tmp_t
- Set files with the inetd_tmp_t type, if you want to store inetd tem‐
porary files in the /tmp directories.
inetd_var_run_t
- Set files with the inetd_var_run_t type, if you want to store the
inetd files under the /run directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly change the file context you need to use the
semanage fcontext command. This will modify the SELinux labeling data‐
base. You will need to use restorecon to apply the labels.
PORT TYPES
SELinux defines port types to represent TCP and UDP ports.
You can see the types associated with a port by using the following
command:
semanage port -l
Policy governs the access confined processes have to these ports.
SELinux inetd policy is very flexible allowing users to setup their
inetd processes in as secure a method as possible.
The following port types are defined for inetd:
inetd_child_port_t
Default Defined Ports:
tcp 1,9,13,19,512,543,544,891,892,2105,5666
udp 1,9,13,19,891,892
PROCESS TYPES
SELinux defines process types (domains) for each process running on the
system
You can see the context of a process using the -Z option to ps
Policy governs the access confined processes have to files. SELinux
inetd policy is very flexible allowing users to setup their inetd pro‐
cesses in as secure a method as possible.
The following process types are defined for inetd:
inetd_t, inetd_child_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
COMMANDS
semanage fcontext can also be used to manipulate default file context
mappings.
semanage permissive can also be used to manipulate whether or not a
process type is permissive.
semanage module can also be used to enable/disable/install/remove pol‐
icy modules.
semanage port can also be used to manipulate the port definitions
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
