The 5* port is on my radar... as I just posted in my cross post). The 4* is ready for prime time IMO, I do have a few bugs that need addressing (I will get to them next week I hope ...sigh) R > > Russell > > [1] It's been two months since I tried. > > : > : On Thu, Oct 21, 2004 at 09:32:48PM +0200, Marco Molteni wrote: > : > SCTP in KAME is complete, stable and fully supported. > : > It is mainly developed by the SCTP RFC author, Randall Stewart. > : > : Randall has been maintaining his SCTP stack on FreeBSD 4.x, > : OpenBSD, and NetBSD.
