Jkaptive is a simple captive portal without RADIUS (and thus without total security, but at the same time without too much hassle). The reason behind this is because a lot of site administrators don't need tight security; their site is just a café that offers free Internet access on an unsecured WLAN access point connected to the Internet, and they need a ticketing system to make it cumbersome for average people to use this offering without actually buying a single coffee. Jkaptive itself just presents the login page and checks the token. The blocking of unticketed traffic is done through Linux' netfilter. As no proxy server is involved, jkaptive has no performance penalty, nor does it create problems with non-HTTP traffic. Once the token is accepted, jkaptive is out of the way of any network packets completely. For presenting the login page, jkaptive has a built-in Web server, so no additional Web server application is needed.
pyforward is a GTK+ front-end to three core Linux technologies that make it possible to turn your computer into a WiFi access point in infrastructure mode. It uses iptables to enable routing of your requests, dnsmasq to assign IP addresses using DHCP, and hostapd to configure WiFi access to your machine in infrastructure mode.
wwan-helper is a script that establishes a UMTS connection using a Ericsson F3507g Mobile Broadband Module. It was designed to be used with a ThinkPad T420s. It takes care of resetting and reinitializing the modem if the hardware fails to get a WWAN connection, and retries as often as necessary until the UMTS connection is really established. It is meant to run as a hook script for the ifup / ifdown mechanism, but should also work on other networking systems.
