The qaul.net-software implements a redundant, open communication principle, in which wireless-enabled computers and mobile devices can directly form a spontaneous network. Text messaging, file sharing and voice calls are possible independent of internet and cellular networks. Qaul.net can spread like a virus, and an Open Source Community can modify it freely. It runs on MacOS, iOS, Windows, Ubuntu, Android alike: https://github.com/qaul/qaul.net.

HTTP File Server, otherwise known as HFS, is a free web server specifically designed for publishing and sharing files. The complete feature set differs from other web servers; it lacks some common features, like CGI, or even ability to run as a Windows service, but includes, for example, counting file downloads. It is even advised against using it as an ordinary web server.

HFS is a small HTTP file server, aimed at mostly sharing files for download.
The official documentation describes HFS as:

  • HFS (Http File Server) is file sharing software which allows you to send and receive files. You can limit this sharing to just a few friends, or be open to the whole world.
  • HFS is different from classic file sharing because there is no network. HFS is a web server which uses web technology to be more compatible with today’s Internet.
  • Since it is actually a web server, your friends can download files as if they were downloading from a website using a web browser, such as Internet Explorer or Firefox. Your users don’t have to install any new software.
  • HFS lets you share your files. Most web servers are used to publish a website, but HFS is not designed to do that. You are, however, free to use it in any way you wish, – but at your own risk.

PeerVPN is a software that builds virtual ethernet networks between multiple computers. Such a virtual network can be useful to facilitate direct communication that applications like file sharing or gaming may need. Often, such direct communication is made impossible or very difficult by firewalls or NAT devices.

Most traditional VPN solutions follow the client-server principle, which means that all participating nodes connect to a central server. This creates a star topology, which has some disadvantages. The central node needs lots of bandwith, because it needs to handle all the VPN traffic. Also, if the central node goes down, the whole VPN is down too.

A virtual network built by PeerVPN uses a full mesh topology. All nodes talk directly to each other, there is no need for a central server. If one node goes down, the rest of the network is unaffected.

Configuring PeerVPN is easy. You just need to configure a network name, a password and the contact information (IP address and port) of another PeerVPN node. Adding a new node to an existing network doesn’t require the existing nodes to alter their configuration, because its IP address is automatically distributed across the whole virtual network: peervpn.net.
