NAME

semanage - SELinux Policy Management tool

 

SYNOPSIS

semanage {boolean|login|user|port|interface|node|fcontext} -{l|D} [-n] [-S store]
semanage boolean -{d|m} [--on|--off|-1|-0] -F boolean | boolean_file
semanage login -{a|d|m} [-sr] login_name | %groupname
semanage user -{a|d|m} [-LrRP] selinux_name
semanage port -{a|d|m} [-tr] [-p proto] port | port_range
semanage interface -{a|d|m} [-tr] interface_spec
semanage node -{a|d|m} [-tr] [ -p protocol ] [-M netmask] address
semanage fcontext -{a|d|m} [-frst] file_spec
semanage permissive -{a|d} type
semanage -i command-file
semanage dontaudit [ on | off ]

 

DESCRIPTION

semanage is used to configure certain elements of SELinux policy without requiring modification to or recompilation from policy sources. This includes the mapping from Linux usernames to SELinux user identities (which controls the initial security context assigned to Linux users when they login and bounds their authorized role set) as well as security context mappings for various kinds of objects, such as network ports, interfaces, and nodes (hosts) as well as the file context mapping. See the EXAMPLES section below for some examples of common usage. Note that the semanage login command deals with the mapping from Linux usernames (logins) to SELinux user identities, while the semanage user command deals with the mapping from SELinux user identities to authorized role sets. In most cases, only the former mapping needs to be adjusted by the administrator; the latter is principally defined by the base policy and usually does not require modification.

 

OPTIONS

-a, --add
Add a OBJECT record NAME
-d, --delete
Delete a OBJECT record NAME
-D, --deleteall
Remove all OBJECTS local customizations
-f, --ftype
File Type. This is used with fcontext. Requires a file type as shown in the mode field by ls, e.g. use -d to match only directories or -- to match only regular files.
-F, --file
Set multiple records from the input file. When used with the -l --list, it will output the current settings to stdout in the proper format.

Currently booleans only.

-h, --help
display this message
-l, --list
List the OBJECTS
-C, --locallist
List only locally defined settings, not base policy settings.
-L, --level
Default SELinux Level for SELinux use, s0 Default. (MLS/MCS Systems only)
-m, --modify
Modify a OBJECT record NAME
-n, --noheading
Do not print heading when listing OBJECTS.
-p, --proto
Protocol for the specified port (tcp|udp) or internet protocol version for the specified node (ipv4|ipv6).
-r, --range
MLS/MCS Security Range (MLS/MCS Systems only)
-R, --role
SELinux Roles. You must enclose multiple roles within quotes, separate by spaces. Or specify -R multiple times.
-P, --prefix
SELinux Prefix. Prefix added to home_dir_t and home_t for labeling users home directories.
-s, --seuser
SELinux user name
-S, --store
Select and alternate SELinux store to manage
-t, --type
SELinux Type for the object
-i
Take a set of commands from a specified file and load them in a single transaction.

 

EXAMPLE

# View SELinux user mappings
$ semanage user -l
# Allow joe to login as staff_u
$ semanage login -a -s staff_u joe
# Allow the group clerks to login as user_u
$ semanage login -a -s user_u %clerks
# Add file-context for everything under /web (used by restorecon)
$ semanage fcontext -a -t httpd_sys_content_t "/web(/.*)?"
# Allow Apache to listen on port 81
$ semanage port -a -t http_port_t -p tcp 81
# Change apache to a permissive domain
$ semanage permissive -a httpd_t
# Turn off dontaudit rules
$ semanage dontaudit off
