Ubuntu 18.04 VFIO GPU passthrough with a single GPU (onboard automatically disables itself)

Hardware

https://www.reddit.com/r/JDM_WAAAT/comments/8zgkfj/server_build_nas_killer_v_20_the_terminator_dual/ 2x X5650 from this thread Aside from that build guide, a generic USB3 card and an AMD R9-200

Grub

Modify /etc/default/grub and add vfio-pci.ids=dead:beef video=efifb:off to GRUB_CMDLINE_LINUX_DEFAULT (use the PCI vid/pid of your primary GPU, not dead:beef)

Proposal: Node.js penetration test framework

Hi guys! Since I started to write Bluebox-ng I've been tracking the different security projects I found written in Node.js. Now we've published the first stable version we think it's the right moment to speak among us (and, of course, everyone interested in it :).

Why?

• I think we're rewriting the same stuff in our respective projects again and again. For example, almost any tool supports IPv6 because the functions we need are still not present in the Node core and the libraries I found (IMHO) were not enough.
• There're different projects implementing exactly the same thing, ie: port scanners.
• We're working in a too new environment, so we need to make it together.
