about getsebool and setsebool

The setsebool is used to set SELinux boolean value i.e. various configurations can be enabled or disabled using this tool. In other words, the setsebool command switches on and off the protection of SELinux. Type getsebool -a to see all such options which can be enabled or disabled at run time: e.g. # getsebool -a The following should give you a complete listing of all the vsftpd switches: e.g. # getsebool -a | grep ftp For example, if httpd_disable_trans set to 1, it will disable SELinux protection for Apache web server. To disable it, enter: # setsebool -P httpd_can_network_connect=1 To enable it, enter: # setsebool -P httpd_can_network_connect=0
