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.
