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
