semanage

SELinux persistent policy management tool. Some subcommands such as boolean, fcontext, port, etc. have their own usage documentation. More information: https://manned.org/semanage.

Set or unset a SELinux boolean. Booleans allow the administrator to customize how policy rules affect confined process types (a.k.a domains):

sudo semanage boolean {{-m|--modify}} {{-1|--on|-0|--off}} {{haproxy_connect_any}}

Add a user-defined file context labeling rule. File contexts define what files confined domains are allowed to access:

sudo semanage fcontext {{-a|--add}} {{-t|--type}} {{samba_share_t}} '/mnt/share(/.*)?'

Add a user-defined port labeling rule. Port labels define what ports confined domains are allowed to listen on:

sudo semanage port {{-a|--add}} {{-t|--type}} {{ssh_port_t}} {{-p|--proto}} {{tcp}} {{22000}}

Set or unset permissive mode for a confined domain. Per-domain permissive mode allows more granular control compared to setenforce:

sudo semanage permissive {{-a|--add|-d|--delete}} {{httpd_t}}

Output local customizations in the default store:

sudo semanage export {{-f|--output_file}} {{path/to/file}}

Import a file generated by semanage export into local customizations (CAREFUL: may remove current customizations!):

sudo semanage import {{-f|--input_file}} {{path/to/file}}
