Students and teachers can store their documents, calendars, contacts and photos locally within [Nextcloud](https://nextcloud.com), which is much like having a (local) version of Dropbox or Google Drive on your very own [Internet-in-a-Box](http://internet-in-a-box.org).
(1) Set these 2 variable in [/etc/iiab/local_vars.yml](http://FAQ.IIAB.IO#What_is_local_vars.yml_and_how_do_I_customize_it.3F) prior to installing Internet-in-a-Box:
To further refine Nextcloud access controls based on IPv4 addresses, you can edit `/etc/apache2/sites-available/nextcloud.conf`_after_ it's created by this template: [/opt/iiab/iiab/roles/nextcloud/templates/nextcloud.conf.j2](https://github.com/iiab/iiab/blob/master/roles/nextcloud/templates/nextcloud.conf.j2)</strike>
(3) Strongly consider also setting `nginx_high_php_limits: True` in your /etc/iiab/local_vars.yml, to allocate important RAM/resources to PHP. Of course, enabling this might cause excess use of RAM/disk or other resources if not calibrated to your hardware and network! So _after_ install is complete, verify and evaluate these 5 settings in /etc/php/[ACTUAL PHP VERSION]/fpm/php.ini:
Useful PHP recommendations for these settings (while largely tailored to WordPress, and aimed at very low-end hardware) can be found here: [/opt/iiab/iiab/roles/www_front_end/tasks/main.yml#L47-L51](../www_front_end/tasks/main.yml#L47-L51)
