IIAB/Security

Some security tips that will become more professional as time goes on:

• The following applies to CentOS-based XSCE school servers, towards downloading and automatically installing recent security patches & updates, that is if you have a reasonably fast connection, and are willing to take risks with certain packages breaking.

• run "yum -y update --security" if your system already has yum-security installed, typically via [(background) "yum install yum-security"]. In the past we ran "yum -y update" but that installs far too many untested and diverse updates/upgrades across the board, adding features not directly related to security.

• if you notice Wikipedia-like item are no longer accessible from http://schoolserver.lan, try running the following as root:

 xsce-make-kiwix-lib
 systemctl restart kiwix-serve

• if ownCloud updates itself, users visiting http://schoolserver.lan/owncloud may face error message "You don't have permission to access /owncloud on this server." Fix guideline forthcoming.
