Coming Soon to OpenBSD/amd64: A Native Hypervisor reddit / BSD ---------------------------------------------------------------------- smileybone · 2015-08-31 21:32 Didn't think openBSD would ever do this. Hasn't somebody from the core team gone on record against the security risks hardware virtualization has? ---------------------------------------------------------------------- naikaku · 2015-08-31 21:53 Can't wait to try it out! Never thought I'd see hyper visor support on openbsd. ---------------------------------------------------------------------- _xsgb · 2015-09-01 00:01 The first protected to the bug of the year 2038 will be the last to support virtualization! ---------------------------------------------------------------------- andermetalsh · 2015-09-01 00:13 Is hell frozen now? ---------------------------------------------------------------------- wartzilla · 2015-09-01 00:14 They use hardware accelerators for crypto too, you know. ---------------------------------------------------------------------- BumpitySnook · 2015-09-01 00:51 From the top, it's Theo. ---------------------------------------------------------------------- smileybone · 2015-09-01 00:58 Ok that is a convenience/security tradeoff, but its not in same ballpark as virtualization imo. I wouldve guessed they'd improve containerization first. ---------------------------------------------------------------------- sweet_cakes_2600 · 2015-09-01 07:04 I had not heard of `cu(1)` before. Can it be used for regular serial communication? Previously I've been using `screen(1)` for that but `screen(1)` is not part of base OpenBSD nor of base FreeBSD so if I can use `cu(1)` instead, I'll have one less extra software to install. ---------------------------------------------------------------------- nanthiel · 2015-09-01 07:33 As far as I know, they're only used as a source of noise, not for actual crypto. https://youtu.be/aWmLWx8ut20 ---------------------------------------------------------------------- zmyrgel · 2015-09-01 07:48 http://www.openbsd.org/cgi-bin/man.cgi/OpenBSD- current/man1/cu.1?query=cu&sec=1 ---------------------------------------------------------------------- phessler · 2015-09-01 08:13 They used to be used for actual crypto, but we discovered 5+ years ago they actually slowed down crypto performance. ---------------------------------------------------------------------- phessler · 2015-09-01 08:14 Yes, cu(1) (and tip) was the original program for serial communications. ---------------------------------------------------------------------- sweet_cakes_2600 · 2015-09-01 22:19 Sweet :D ---------------------------------------------------------------------- sweet_cakes_2600 · 2015-09-01 22:25 Well now I feel embarassed. My question was answered right in the NAME section and further detailed in the first paragraph of the DESCRIPTION. In my defense, I did check the man-page but the problem was that I did so on a GNU/Linux system. Here's what their man-page for `cu(1)` looks like: http://linux.die.net/man/1/cu. It's another command alltogether.
