The Open1x Project has two components: xsupplicant and authenticator. Xsupplicant is an implementation of the supplicant (i.e., client) side of the 802.1X protocol and works under Linux and Mac OS X. Authenticator is an implementation of the authenticator and works only under Linux.

xsupplicant provides client-side authentication, key negotiation, and association management for 802.1x/802.11i protected networks. It can be used on computers with wired or wireless LAN connections to complete a strong authentication before joining the network. Install this software if you need to connect to a WPA, WPA2, or other 802.1x protected network.
