.SH "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.

.SH "OPTIONS"
.TP
.I                \-a, \-\-add        
Add a OBJECT record NAME
.TP
.I                \-d, \-\-delete     
Delete a OBJECT record NAME
.TP
.I                \-D, \-\-deleteall
Remove all OBJECTS local customizations
.TP
.I                \-\-disable
Disable a policy module, requires -m option

Currently modules only.
.TP
.I                \-\-enable
Enable a disabled policy module, requires -m option

Currently modules only.
.TP
.I                \-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.
.TP
.I                \-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.
.TP
.I                \-h, \-\-help       
display this message
.TP
.I                \-l, \-\-list       
List the OBJECTS
.TP
.I                \-C, \-\-locallist
List only locally defined settings, not base policy settings.
.TP
.I                \-L, \-\-level
Default SELinux Level for SELinux use, s0 Default. (MLS/MCS Systems only)
.TP
.I                \-m, \-\-modify     
Modify a OBJECT record NAME
.TP
.I                \-n, \-\-noheading

.TP
.I                \-p, \-\-proto
Protocol for the specified port (tcp|udp) or internet protocol version for the specified node (ipv4|ipv6).
.TP
.I                \-r, \-\-range      
MLS/MCS Security Range (MLS/MCS Systems only)
.TP
.I                \-R, \-\-role
SELinux Roles.  You must enclose multiple roles within quotes, separate by spaces. Or specify \-R multiple times.
.TP
.I                \-P, \-\-prefix
SELinux Prefix.  Prefix added to home_dir_t and home_t for labeling users home directories.
.TP
.I                \-s, \-\-seuser     
SELinux user name
.TP
.I                \-S, \-\-store
Select and alternate SELinux store to manage
.TP
.I                \-t, \-\-type       
SELinux Type for the object
.TP
.I                \-i
Take a set of commands from a specified file and load them in a single
transaction.

.SH EXAMPLE
.nf
# 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

.B Managing multiple machines
Multiple machines that need the same customizations.
Extract customizations off first machine, copy them
to second and import them.

# semanage -o /tmp/local.selinux
# scp /tmp/local.selinux secondmachine:/tmp
# ssh secondmachine
# semanage -i /tmp/local.selinux

If these customizations include file context, you need to apply the
context using restorecon.
