NextCloud

NextCloud is a system for file synchronisation and also has many other plugins for calendar, videoconferencing, collaborative document editing and federated file sharing. It's a lot more elaborate than Syncthing, but there may be situations where centralized control of your files on your server is better than a purely peer-to-peer approach (eg. if you need to remove a user's access to files).

The videoconferencing plugin requires a browser with WebRTC support and so is unlikely to work in a Tor browser, but may still be a better option than using proprietary systems.

Installation

Log into your system with:

ssh myusername@mydomain -p 2222

Using cursor keys, space bar and Enter key select Administrator controls and type in your password.

Select Add/Remove Apps then nextcloud. You will then be asked for a domain name and if you are using FreeDNS also the code for the domain which can be found under Dynamic DNS on the FreeDNS site (the random string from "quick cron example" which appears after update.php? and before >>). For more details on obtaining a domain and making it accessible via dynamic DNS see the FAQ. Typically the domain name you use will be a subdomain, such as cloud.mydomainname.net. It will need to be a domain which you have bought somewhere and own and not one of the FreeDNS subdomains, otherwise you won't be able to get a SSL/TLS certificate for it.

Initial setup

Go to the Administrator control panel and select Passwords then nextcloud. This will give you the password to initially log in to the system and you can change it later from a client app if needed.

With a browser navigate to the domain which you gave during installation and log in.

You can also install the mobile client from F-droid.
