You can customize an SELinux policy by enabling or disabling the members of a set of boolean values. Any changes that you make take effect immediately and do not require a reboot.

You can set the boolean values in the Boolean view of the SELinux Administration GUI.

Alternatively, to display all boolean values together with a short description, use the following command:

# semanage boolean -l
SELinux boolean    State  Default Description

ftp_home_dir       (off  ,  off)  Allow ftp to read and write files in the user home ...
smartmon_3ware     (off  ,  off)  Enable additional permissions needed to support dev...
xdm_sysadm_login   (off  ,  off)  Allow xdm logins as sysadm
.
.
.

You can use the getsebool and setsebool commands to display and set the value of a specific boolean.

# getsebool boolean
# setsebool boolean on|off

For example, to display and set the value of the ftp_home_dir boolean:

# getsebool ftp_home_dir
ftp_home_dir --> off
# setsebool ftp_home_dir on
# getsebool ftp_home_dir
ftp_home_dir --> on

To toggle the value of a boolean, use the togglesebool command as shown in this example:

# togglesebool ftp_home_dir
ftp_home_dir: inactive

To make the value of a boolean persist across reboots, specify the -P option to setsebool, for example:

# setsebool -P ftp_home_dir on
# getsebool ftp_home_dir
ftp_home_dir --> on
