Additionally, if you have physical access anyway, you can be a literal man-in-the-middle, bridging all traffic and keeping a copy for yourself. You could probably do something with the tun(4) device. And there's probablly some l2tp software in ports/net that would fit your needs (tund, vtun). l2tp would have higher latency and overhead then just encrypting ethernet payloads, but it has the advantage of being already available. -Jason ----------------------------------------------------------------------- I worry about my child and the Internet all the time, even though she's too young to have logged on yet. Here's what I worry about. I worry that 10 or 15 years from now, she will come to me and say "Daddy, where were you when they took freedom of the press away from the Internet?" -- Mike Godwin -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (FreeBSD) Comment: See https://private.idealab.com/public/jason/jason.gpg iD8DBQE890WaswXMWWtptckRAiPbAKDABp8cdDODFlyQq7Z7K13bvsvDoACgqk6E Qu4UmqGSe+AP1SJroLBvfl8= =C0gU -----END PGP SIGNATURE----- To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-security" in the body of the message
