semanage boolean -l
THere are a lot so should consider using grep
THis shows 2 states first one is current status and second is the persistent
You can also see the status of booleans with
getsebool -a
again consider using grep
To turn on a boolean use
setsebool -P boolean_name on
-P is persistent
To see what changes have been done locally use
semanage boolean -l -C
