FreeS/WAN is a free implementation of IPsec & IKE for Linux. Although IPsec will be added to the kernel as of 2.5, FreeS/WAN still maintains some benefits. The FreeS/WAN project came to an end on 2003/04/22. A few months before, most people active in the project forked the code in Openswan (http://www.openswan.org/)
Opportunistic Encryption (http://www.freeswan.org/freeswan-trees/CURRENT-TREE/doc/quickstart.html) – enables you to set up IPsec tunnels without co-ordinating with another site administrator, and without hand configuring each tunnel. If enough sites support OE, a “FAX effect” occurs, and many of us can communicate without eavesdroppers.
