On Sun, Mar 29, 2015 at 03:30:07PM -0400, Rich Freeman wrote With TPM, full-disk encryption, and a verified boot path, you could actually protect against that scenario (they'd have to tear apart the TPM chip and try to access the non-volatile storage directly, and the chips are specifically designed to defeat this). Secure boot would not hurt either (with your own keys). Of course, they could still try to hack in via USB/PCI/etc, or plant keyloggers and such. I'm not suggesting physical security isn't important. It just isn't a good reason to completely neglect console security. Be careful what you wish for. I have my doubts that TPM chips would boot linux with Microsoft offering volume discounts to OEMS.

Yeah, but I have to be in the directory where the ebuild lives for that to work. `emerge foo` works anywhere.

That's way easier to get a well defined result than hitting C-c :)

So you are saying that the error comes from a bios errata (and don't know what microdode is), and the fix is to update bios? An “errate” is what Intel calls an error or defect in its hardware, as far as I know. Microcode is sort of a “firmware” running in a CPU. For example, the TSX feature in Haswells (which was one of the reasons why I chose my particular CPU in the first place, grrr) was found to have a bug, so Intel produced a microcode update that would simply disable the relevant set of instructions. no, possibly from a CPU errata and a bios update might bring in the microcode update that works around that. I see, thanks for clarifying that. So looks like not too many options, either try to update the bios and/or replace the CPU. Not necessarily.

Go in the bios menu and reset it to safe defaults or similar setting. If that don't work play with the settings, especially memory settings (try lowering the frequency). 2. If the motherboard is dirty, clean it real good. This may sound crazy but I've had success spray washing it with a hose and drying it on a warm oven. 3. Flash the bios with the latest version. 4. If you have a soldering iron and junk parts laying around replace any blown capacitors on the board. The first one I already try with no luck. Now you mention it, it is a little dusty the motherboard... and looking carefully I think it could be some capacitors may are some blow (but not for sure). Thank you very much for the tips, I'll try them all!

I have no idea if gummiboot or any of the EFI solutions do (presumably direct to linux works) - you'd need a TPM-aware bootloader to take advantage of TPM-based full-disk encryption unless you want to be typing in a password when you boot. A TPM is still useful with password-based boots since it can enforce a maximum number of guesses before it destroys the key. However, the real magic is when you use a verified boot path so that your system just magically boots into linux if the boot path is not tampered with, and if not the hard drive is impossible to read (and you can do all this while keeping a copy of your disk key safely offline just in case). Remember, TPM isn't UEFI - it works differently and has been around in PCs a lot longer. -- Rich

The first one had such a bad homogeneity of luminance that I sent it back instantly. The second one was a lot better but nevertheless not as good as my Acer and after some days of thinking I also sent it back. Same thing with my new Samsung monitor. The first one I received had a big problem with backlight bleeding so I contact the vendor. They exchanged the monitor and the second one was ok. It also has a little backlight bleeding on the upper left side, but it is only slightly visible when watching dark pictures in a low light environment. At normal conditions it is invisible. So I decided to stay with this one. It seems that these days the quality of a lot of products fluctuates, even in the professional domain. Of course that depends on the quality control of the manufactures. But even very expensive products (like professional camera lenses) from well-known manufactures are often concerned by quality variability. But if you buy online, you always have the option to send back a unsatisfactory product. to fluctuate a lot. And while I do some photography, I don’t do it professionally or deal with printing. A wide gamut monitor is a great thing even if you don't need it for softproofing. I shot a lot of colorful photos (e.g. from bugs, blossoms and live concerts with colored limelights). They look great on an AdobeRGB monitor but much more boring on a standard monitor. It's the same with UHD. The sharpness is amazing. I never saw my photos in such a great quality. Everything looks so clear and realistic, almost three-dimensional. I never planned to spent so much money for a monitor, and the expense still hurts. But since I have it I never wanna give it away. :-) If your monitor don't have a wide gamut but have a LED backlight then some of the cheaper colorimeters are also not suitable because LEDs doesn't emit a continuous spectrum and thus can confuse older colorimeters like the Spyder2 AFAIK. That’s good to know. I decided for an Eizo with a standard IPS panel and probably white LEDs. It is reported to have a good colorspace I also thought about buying an Eizo. But they are very pricy. An Eizo without wide gamut, without factory calibration and without 16bit LUT hardware calibration costs more as my Samsung with all these features. Maybe the Eizo is more reliable over the years, but who knows. coverage, though. But as I mentioned, ideally I also want to use it on my laptop which has a very bad TN panel with LEDs. Perhaps I could even use it on my very old CCFL monitor which is still in very good shape. Try out an Spider4. You can buy it as a new device for about 75€. Test the results on your monitors and when you are not satisfied, just send it back. No risk at all. You can also buy a Spyder2 at ebay. A friend of mine bought one for 20€. Of course you can't send it back when it doesn't work for you (I don't know if it works well with LED backlights). -- Regards wabe

It's because a user who wants to somewhat permanently disrupt the services the machine provides would need to remain at the keyboard to continue to reboot it and thus can be caught more easily than a user who shuts the machine down and then escapes. This is assuming that a user who does such things isn't smart enough to enter the BIOS setup before they escape, which characterizes users doing such things. That leaves the question why a user who isn't even logged in should be able to reboot, which IIRC they can by default with Ctrl+Alt+Del.

The user can reboot the system, but can't shut down ? Strange The thinking is that you can unplug the machine or press the hardware reset or power button or flip the PSU switch ... Preventing a ctrl+alt+del reboot does not add anything to security. Security doesn't apply to users with physical access to the machine. However, this is just a default. You can easily disable reboot on ctrl+alt+del by editing /etc/inittab and commenting-out this line: ca:12345:ctrlaltdel:/sbin/shutdown -r now Testing my single-user box with the above line in inittab , I find that if I enter 'A-^Del' , I exit X to the raw terminal ; That's usually Ctrl+Alt+Backspace. I had to turn that off with 'Option DontZap true' in the server section of xorg.conf because I somehow happen to press that accidentally about once a month :/ The 1st effect is explained in ~/.fluxbox/keys by # exit fluxbox Control Mod1 Delete :Exit So whatever handles keyboard inputs with the X server even intercepts Ctrl+Alt+Del? Does fluxbox quit all programs nicely before it exits? However, the 2nd effect is not explained so easily : 'A-^Del' reboots when entered at a raw terminal, but 'shutdown -r now' does not, yet the former is defined as the latter by the line above in my /etc/inittab . The cause seems to be that 'A-^Del' is intercepted by 'init' (Process 1), which is owned by root, but 'shutdown -r now' is heard by Process 910 -- 'bash' running in the raw terminal, which was started by 'init' -- , which is owned by my user. So the behaviour is explained, but following my earlier msg, which advised to follow proper Unix principles, I should comment the 'A-^Del' line in inittab : if the raw terminal can't react to 'su', it won't react to 'A-^Del' either, so there's no justification in terms of escaping from an emergency. What happens when you comment out the entry in inittab and someone presses Ctrl+Alt+Del? Nothing? pressing the reset button is far worse, since there's no clean shutdown, unmounting filesystems after flushing caches, etc. Yes : that's forced only when the keyboard ceases to respond. Because of that, the default of allowing ctrl+alt+del for local users makes more sense than disabling it. That doesn't follow : if you have multiple users, you don't want some rogue user rebooting randomly ; it makes sense only as a convenience on a single-user system. It seems to be the default behaviour of 'inittab' -- there no comment saying I set it myself, which I would have added -- , which is not appropriate for Gentoo systems in general, some of which are undoubtedly multi-user. Undefined behaviour as the default also isn't ideal, and I agree that nothing happens would be much better: What's the last time you pressed Ctrl+Alt+Del and it actually worked? It's a legacy thing from times when freezes/crashes were common and when it did work and was useful. Nowadays, when you're pressing it, usually nothing happens anyway because the machine is down to where you have to press the reset button or to turn off the power (if you can't log in with ssh). When the machine still works, Ctrl+Alt+Del also works, which means that the default does nothing but create a security hole. So how can we have this default changed? -- Again we must be afraid of speaking of daemons for fear that daemons might swallow us. Finally, this fear has become reasonable.

Well, the old answer would be that you need to use sudo to run it, as
shutting down is a privileged operation.
I suspect that the new answer is that with appropriate
policykit/consolekit/etc settings you can probably allow somebody
sitting at a physical console to shut down the system, or any
logged-in user if you prefer. However, I haven't actually set that up
myself.
logind does that for you automagically™. The first seat has the rights to
poweroff or reboot the machine, and it can differentiate between local and
remote logins. You can check if your user session has the permissions to
poweroff/reboot via dbus:
$ gdbus call --system --dest org.freedesktop.login1 --object-path
/org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanPowerOff
('yes',)
$ gdbus call --system --dest org.freedesktop.login1 --object-path
/org/freedesktop/login1 --method org.freedesktop.login1.Manager.CanReboot
('yes',)
But you need systemd to use logind1. There has been some attempts to
reimplement logind outside systemd, but I'm not sure how advanced they are.
This kind of problems were one of the reasons for creating logind.
and dump people keep talking nonsencely that sysvinit is enough while it
cannot even handle reboot for normal user. sad.
it can. Did for decaded.
Dumb systemd fanbois spouting their lies everywhere. Sad.

As to fonts, I highly recommend Source Code Pro and Source Sans Pro.
They finally resolved my long search for good fonts. Unfortunately,
they don't come with Gentoo. I copied them over from a Fedora
installation, so you might be able to extract them from their RPMs.
I haven't been able to create them from their sources, though. It
requires some special program which didn't work. Maybe someone knows
how to do that?
No need to extract them, they come with Gentoo unstable

With TPM, full-disk encryption, and a verified boot path, you could actually protect against that scenario (they'd have to tear apart the TPM chip and try to access the non-volatile storage directly, and the chips are specifically designed to defeat this). Secure boot would not hurt either (with your own keys). Of course, they could still try to hack in via USB/PCI/etc, or plant keyloggers and such. I'm not suggesting physical security isn't important. It just isn't a good reason to completely neglect console security. -- Rich

Stefan Yes, actually it can be time consuming to have - and keep - a running Gentoo system. To me, it's something like a life insurance having btrfs on my system disk. So I can step back when I discover something important stopped working without me having noticed immediately.

This is Gentoo, it's all about choice. Sometimes there's a downside, like a very long package.use to define to Portage exactly what your choice really is.
