Since we first started talking about using the browser as an authentication tool in December 2000 OpenSource implementations have started to appear. Here is a list of all the software I know of that implements either a CaptivePortal or an ActivePortal solution.

LiveCD

• ZoneCD Gateway http://www.publicip.net/ with NoCat installed - DennyHalim

• [http://www.lessnetworks.com/ lessnetworks] with NoCat installed - DennyHalim

• [http://talweg.univ-metz.fr/talweg:en:start talweg] Demo LiveCD

Open Source

• [http://talweg.univ-metz.fr/talweg:en:start talweg]

  • It's a http/https captive portal. It uses http redirections to enforce transmissions using a secured https channel. Using of IP/MAC address to maintain sessions are not necessary, the authentication is more secure.

• [http://nocat.net/download/NoCatAuth/ NoCatAuth]

  • Written in perl, supports Linux/iptables and OpenBSD/pfctl. GPLed. Supports authenticating modes against an auth service with a wide variety of backends, including a MySQL database, PAM, RADIUS, LDAP, and more. Also features a non-authenticating "open mode" that merely requires a user to accept an AUP before they can log in. This project is more or less seeking a new maintainer.

• [http://nocat.net/download/NoCatSplash/ NoCatSplash]

  • Written in C, currently under heavy development. Intended to be the successor to NoCatAuth, the gateway process and all its data files fit within 200-250k, making it ideal for embedded environments.

• [http://net.doit.wisc.edu/~dwcarder/captivator/ Captivator-gw]

  • Captive portal that works inline at Layer 2 in your network. Supports vlans and trunk interfaces. Uses arp to detect if users are still connected. Written in perl, and easy to add new features. Developed at the University of Wisconsin - Madison.

• [http://www.cc.saga-u.ac.jp/opengate/index-e.html Opengate developed at Saga University (Japan)]

  • GPLed, runs on FreeBSD. Uses Ajax or Java applet to keep the connection open. Ftp, pop3, pop3s, RADIUS or PAM servers for an authentication back-end. (added by Jim Thompson)

• MetaNet by ErikWalthinsen.

  • Still in early beta but it will provide an entire network application framework rather then just a CaptivePortal solution.

• [http://www.geekspeed.net/wicap/ WiCap] by BrianCaswell

  • Written in Perl and runs under OpenBSD. I believe this is what NovaWireless will be deploying.

• ["WiCap-PHP"] by CalebPhillips

  • Written in 'C' and PHP, runs under OpenBSD. There is a fork written in Python and PHP. A more betterer implementation of WiCap.

• [http://www.river.com/tools/authhb/ River of Stars]

  • Wireless heartbeat implementation (presently most usable on an OpenBSD gateway)

• [http://www.lanroamer.net/soholanroamerdevframe.html LanRoamer] (Linux 2.4.x)

  • Based on the Linux 2.4 kernel and GPL'd. (Name changed to LanRoamer by Jim Thompson)

• [http://slan.sourceforge.net/ SLAN]

  • A GPL'd captive portal implementation using VPN technology. Has Linux and Windows clients.

• [http://ceres.unit.liu.se/netlogon-devel/ Netlogon] by Kent Engström at Linköpings University

  • Not much known, a basic captive portal solution.

• [http://www.itlab.musc.edu/~nathan/authentication_gateway/ Authentication Gateway HOWTO] by Nathan Zorn

  • Uses a PAM module to insert an iptables rule. Very simple and effective. (Added by LimAko).

• [http://software.stockholmopen.net/index.shtml StockholmOpen] by the Royal Institute of Technology in Stockholm, Sweden

  • This system is also operator neutral, allowing different users to connect through the access network to different upstream providers. Implementation in C, uses PAM, Linux/FreeBSD. BSD License. (Added by MartinHedenfalk).

• [http://www.opensplash.org OpenSplash] by Aleksandr Melentiev from San Francisco Wireless

  • Inspired by the simplicity of wicap, intended to run on FreeBSD by utilizing Perl and ipfw. Doesn't provide much functionality, other than a simple AUP agreement. Development version includes abstract authentication system.

• [http://www.chillispot.org ChilliSpot] by Mondru AB

  • ChilliSpot is an open source captive portal or wireless LAN access point controller written in C which supports web based login (external web server required) as well as Wireless Protected Access (WPA), sports a builtin DHCP server and a RADIUS client/proxy server to handle authentication, authorization and accounting (AAA) via an external Radius server. Currently runs on Linux (RedHat, Fedora, Debian binaries and Gentoo ebuild available) but should compile also on FreeBSD, OpenBSD, Solaris, Apple OS X. Previously known as [http://www.mondru.com/hotspotd.html hotspotd], which was available only as binary. Fifth GPL release (0.94): 2004-06-22. (Added by Ovidiu)

• [http://m0n0.ch/wall/ M0n0wall] by Manuel Kasper

  • Embedded Firewall based on FreeBSD that can run from embedded devices as well as PC's. The Captive Portal software included with it allows for button/AUP pass through, as well as authentication using Radius.

• [http://pfsense.org/ pfSense]

  • Firewall based on FreeBSD6 that can run from embedded devices as well as PC's. The Captive Portal software included with it allows for button/AUP pass through, as well as authentication using Radius.

• [http://www.ilesansfil.org/wiki/WiFiDog Wifidog]

  • The WiFiDog project was started by Île sans fil and is currently in production. Existing captive were either almost impossible to embede or only designed to display disclaimers with no access control at all (No Cat Splash and others). WiFiDog is designed to have optional centralized access control, full bandwidth accounting, node heartbeating and local content specific to each hotspot. It does not rely on a javascript window, so it works with any platform with a web browser, including PDAs and cellphones. It is developed in C to make it easy to include in embedded systems (It has been designed for the LinkSys WRT54G, but runs on any recent linux platform). A typical install only takes 30kb on i386, and a fully functionnal install could be made in under 10 kb if necessary.

• [http://www.openbsd.org/faq/pf/authpf.html Authpf]

  • User Shell for Authenticating Gateways on OpenBSD. Authpf(8) is a user shell for authenticating gateways. User logs in using SSH.

  • "To prevent such unauthorized access and hacking, OIT developed its own authentication program requiring wireless users to log in through a web browser before access to the Internet is granted. If a user's connection is inactive for a certain amount of time, the authentication system closes the user's access, deterring potential hackers from taking advantage of the connection."
  • Not quite true. The Starbucks deal was Mobilestar, and there was precious little Microsoft content in the deal (or company). --Jim Thompson
