h.root-servers.net are managed by the United States Army Research Laboratory (ARL), formerly known as the Ballistics Research Laboratory (BRL), and consist of three(3) load-balanced “servers” all running NSD called “h1″, “h2″, “h3″. ARL is home to one of the world’s largest supercomputing facilities and resides on the high-speed Defense Research and Engineering Network (DREN). Current statistics show the three “servers” receive and average of 60 megabytes per second of traffic; around 13,500 UDP packets per second.
l.root-servers.net is operated by the ICANN DNS operations team and was migrated to to NSD on February 6, 2007. This server handles around 8000 queries per second.

> Well I just confirmed (the hard way!) that you are correct. It is possible to reboot the host from inside the container, despite CAP_SYS_REBOOT being blocked. I’ll try & figure out how that’s happening/possible…

It is obvious in retrospect. If you have a container which is sharing the host OS’s root filesystem, then it can see the host’s /dev which contains a /dev/initctrl FIFO pipe. The ‘reboot’ command can tell the host OS to shutdown via that pipe, thus lack of CAP_SYS_REBOOT is irrelevant.

Since this is a FIFO and not a blockdev/chardev we can’t use cgroups to prevent access to /dev/initctrl. The only reliable way is to wait for the kernel’s user namespace stuff.

patiesībā es neatceros gan. bet bija dārgi. vot, skopuma sindroms tāds pats kā vecmāmiņai, kura pārcieta karu ar maziem bērniem.

The idea for the iPad came from an engineer at Microsoft, who was married to a friend of the Jobs family, and who invited Jobs to his fiftieth-birthday party. As Jobs tells Isaacson:
This guy badgered me about how Microsoft was going to completely change the world with this tablet PC software and eliminate all notebook computers, and Apple ought to license his Microsoft software. But he was doing the device all wrong. It had a stylus. As soon as you have a stylus, you’re dead. This dinner was like the tenth time he talked to me about it, and I was so sick of it that I came home and said, “Fuck this, let’s show him what a tablet can really be.”

neuztraucoties par drošību, šāds risinājums ir vnk ideāls. papildus bonuss – viņus var krāmēt virsū uz citas virtuālas mašīnas, piemēram, cita linux iekš ESXi.
