Testing it…no problem for now…there is a NS7 fail2ban package to try with?
EDIT:
UPDATE:
Some litle change to made:
1)Max upload filesize is 2MB!?!?
2)Cron is set to ajax…it will be a good idea to set on cron (last one) and add a cron job:
Add a cron job same user as webserver.
crontab -u apache -e
*/15 * * * * php -f /var/www/html/owncloud/cron.php > /dev/null 2>&1
