Initial import of isakmpd, an IKE (ISAKMP/Oakley) implementation for the
OpenBSD IPSEC stack by me, Niklas Hallqvist and Niels Provos, funded by Ericsson Radio Systems. It is not yet complete or usable in a real scenario but the missing pieces will soon be there. The early commit is for people who wants early access and who are not afraid of looking at source. isakmpd interops with Cisco, Timestep, SSH & Pluto (Linux FreeS/WAN) so far, so it is not that incomplete. It is really mostly configuration that is lacking.
