Why setsebool for httpd not working with -P parameter?

view full story

http://unix.stackexchange.com – I'm trying to disable SELinux for httpd, but when I use the the setsebool command with -P parameter, it doesn't work: setsebool -P http_can_network_connect 1 Nothing happens when I do that ie, the command is apparently running, but returns nothing, and bash is freeze. I'll wait for 10~30 minutes, and nothing happens. Why? (HowTos)
