semanage - SELinux Policy Management tool


semanage {login|user|port|interface|fcontext} -l [-n] semanage login -{a|d|m} [-sr] login_name semanage user -{a|d|m} [-LrRP] selinux_name semanage port -{a|d|m} [-tr] [-p protocol] port | port_range semanage interface -{a|d|m} [-tr] interface_spec semanage fcontext -{a|d|m} [-frst] file_spec


semanage is used to configure certain elements of SELinux policy with- out requiring modification to or recompilation from policy sources. This includes the mapping from Linux usernames to SELinux user identi- ties (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 map- ping. 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 autho- rized 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 Sys- tems 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
