From: http://www.qnx.com/developer/docs/momentics_nc_docs/neutrino/utilities/r/racoon.conf.html "For algorithms that can take variable-length keys, algorithm names can be followed by a key length, like blowfish 448." Have you tried something along the lines of '3des 128' ? Just a guess. -Daxbert To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
