Architecture
Technology
CANSAS 2.0 would not be possible without the hard work done by people driving the following open source projects:
- The authentication portal, code named WRATH (short for Wifidog-Redirected Advertising Tuneable Handler) can be downloaded from this site.
- Debian
is our community-driven GNU/Linux distribution of choice. We reuse most of the networking tools included with it, including the Netfilter firewall included in the kernel and the DNSmasq DHCP and caching DNS server.
- The Apache web server is used to serve web content, it is the de facto standard server, used to serve near the 50% of the Internet sites.
- PHP is the language we used for developing software running at the server.
- For controlling network access the WifiDog gateway daemon is installed at the hotspots.
- PostgreSQL is the database manager of choice: its correctness and reliability are its main stregths. SQLite is a serious contender for embedded environments due to its small size.
License
The project is released under the terms of
version 2 of the GNU General Public License.
