semanage user −{a|d|m} [−LrRP] selinux_name
semanage port −{a|d|m} [−tr] [−p protocol]

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.
−a, −−add
Add a OBJECT record NAME
−d, −−delete
Delete a OBJECT record NAME
−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.
−h, −−help
display this message
−l, −−list
List the OBJECTS
−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).
−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
−t, −−type
SELinux Type for the object
# View SELinux
user mappings
$ semanage user -l
# Allow joe to login as staff_u
$ semanage login -a -s staff_u joe
# 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
