Squid — web-интерфейс для включения/отключения доступа к internet

С помощью этого web-интерфейса редактируется список, на который предполагается включать/отключать инет.
Предпогагается, что у нас есть установленный и настроенный squid, со строчкой в squid.conf:

acl user_list src "/usr/local/etc/squid/users"

для которого потом каким-то образом определяются права доступа к инету.
Файлы будут находиться, например, в /usr/home/public_html/username/squid/
ln -s /usr/home/public_html/username/squid/userlist /usr/local/etc/squid/users

Права:
chown -R www:www /usr/home/public_html/username/squid/ find /usr/home/public_html/username/squid/ -type f -exec chmod 666 {} \; find /usr/home/public_html/username/squid/ -type d -exec chmod 777 {} \; find /usr/home/public_html/username/squid/ -type f -name '*.sh' -exec chmod 777 {} \;
Также пользователь www должен быть в группе wheel — правим /etc/groups

wheel:*:0:root,username,www

ну и правильно настроенное sudo
