[SOLVED] Booting a luks encrypted system directly from UEFI firmware

I've been struggling somewhat with my first UEFI machine (a Toshiba laptop).
The wiki got me to a basic four-partition install okay, and then after a small amount of pain I managed to get a build booted okay from gummiboot and with with root, swap and home luks-encrypted.
What I'm trying to do now is boot directly from the UEFI using an appropriate firmware entry, ie with something like what's described in the EFISTUB Wiki page:
# efibootmgr -d /dev/sdX -p Y -c -L "Arch Linux" -l /vmlinuz-linux -u "root=/dev/sda2 rw initrd=/initramfs-linux.img"
...but I've been unable to achieve this with luks-encrypted partitions. Has anyone here had any success? Is there a "-u" parameter in the above command that will achieve this? I've certainly not found anything online explaining how this can be done, so maybe I'm being unrealistic and expecting too much.

You're a star - that works perfectly.
I wondered about lifting that syntax from "$esp/loader/entries/arch-encrypted.conf" in my last instalation but stupidly thought it was gummiboot-specific.
I'm as surprised that I couldn't find your solution on the web as I am that so few people seem interested in using UEFI firmware in this way. It seems like PC hardware has at last "grown up", with a versatile firmware that must have been a long time in collaborative development - something akin to Sun's OpenBoot - but the community's response has been to create another raft of boot loaders to sit on top of it. Maybe I'm missing something.
Thanks very much for your help.

[SOLVED] Installation with LUKS encryption--ok to grub, then black s..

Installation with LUKS encryption--ok to grub, then black screen
I'm trying to install ArchLinux onto an existing Luks encrypted HDD, formerly dual boot with Fedora 17.
First,I left the Windows partition unchanged and erased the root partition. Then I booted to the ArchLinux, mounted and decrypted the LVM encrypted volume group partitions and followed along with the Beginner's Guide Installation Instructions. This progressed without a hitch; near as I can tell. I can boot to grub select kernel interface, but no further.
So I forgot something...the encrypted volume. I found the archLinux page dm-crypt with LUKS and tried my best to follow along encouraged by the first line, "The installation of a LUKS-encrypted system is largely the same as installing an unencrypted system."
And that's where I stand. I edited the grub.cfg to boot to run level 3, but the kernel doesn't seem to load at all and never starts to give me the chance to enter the password. So now I'm not sure if its the LUKS encryption after all. (maybe its my _next_ problem)
Any ideas?

Sure, here's the layout,

├─cryptVG-home (dm-3) ext4 home xxxxxxxxxxxxxxxxxxxxxxxxxxxx /home
└─cryptVG-local (dm-4) ext4 local xxxxxxxxxxxxxxxxxxxxxxxxxxxx /usr/local
I left sda1 alone. Reinstalled on sda2 (/boot) and sda3 (cryptVG-root). I also remade swap. I didn't see an opportunity to set /usr/local, so I may simply free up this space after copying the data. But for home I set up a sub directory for the new install and left the old user in place (something I've been wanting to accomplish for some time as anaconda is not so nice to old user files).

Kernel updates kill my luks encrypted system

All right, this is weird. I have a 64bit system with encrypted root, home and swap partitions. To setup I followed the wiki here:
https://wiki.archlinux.org/index.php/LUKS
My swap is encrypted like described here:
https://wiki.archlinux.org/index.php/LU … sk_support
Since the updates to kernel 3.1 each new kernel update kills my system. Pacman says while upgrading

So the generation of the initramfs seems to be ok.
But when I reboot this box, I get:
running hook [openswap]

running hook [resume]
waiting 10 seconds for device /dev/mapper/swapDevice
waiting 10 seconds for device /dev/mapper/root
root device /dev/mapper/root doesn't exist. Attempting to create it.
ERROR: unable to determine major/minor number of root device /dev/mapper/root
/dev/sda4 is my swap partition. Then I get dropped to a recovery shell which I can't use because my (usb) keyboard is not working.
Now the funny part. I start the box from a install cd and chroot into the existing installation. I do a
mkinitcpio -p linux
The initramfs is regenerated and it works again! What the hell is pacman doing other than regenerate the initramfs with my presets?

New kernel 3.1.1 did it again. My system hangs in initramfs after the reboot. Same as before: a simple rebuild without any changes fixed the boot process. This time I was able to backup the 'bad' initramfs before chrooting in and rebuilding.
it is very funny to see the content of the 'bad' initramfs image - it is nearly empty!

For some reason the initramfs built by pacman is missing all modules. To say it again, nothing changed, simple rebuilt by mkinitcpio -p linux!
This seems to be a bad bug...

Best way to securely backup LVM on LUKS encrypted system

I'm upgrading harddisks and would like to backup my system to external storage and restore it on the new disk
This is the high level plan:
1. use ecryptfs to create an encrypted directory on a mounted external stroage device
2. mount ecryptfs directory
3. use rsync to make a backup into the ecryptfs directory
4. swap harddisks
5. use an arch live usb to encrypt and partition new disk (LVM on LUKS)
6. mount external storage and mount encrypted ecryptfs on the storage
7. restore system with rsync
Is this the way to do it?
After reading a little on ecryptfs, it seems like the passphrase and keys I create work only for the current kernel using ecryptfs (adds to the kernel key ring). So my understanding is that if I try to decrypt and mount the ecryptfs using a live arch usb, I won't be able to.
Any clarification of the process would be of great help! Thank you

clfarron4 wrote:Any particular reason you're planning to use eCryptfs for the backup and LUKS for the actual system when you could use LUKS for both?
No particular reason for ecryptfs. I believe my two options are ecryptfs and encfs as described in the disk encryption comparison table: https://wiki.archlinux.org/index.php/Di … ison_table

I'm not sure whether this is how it works. Could you show us the documentation which led you to this conclusion please?
I'm also not very familiar with keyrings and how the kernel manages it, or whether it's possible to do what I want with ecryptfs.

[solved] kernel 2.6.27 - open LUKS encrypted root partition fails

Hi,
after updating to kernel 2.6.27 the passphrase for my LUKS encrypted root partition does not work anymore.
I get this error messages:
Enter LUKS passphrase:
device-mapper: table: 254:0 crypt: Error allocating crypto tfm
device-mapper: ioctl: error adding target to table
device-mapper: ioctl: device doesn't appear to be in the dev hash table.
Command failed: No key available with this passphrase.
Enter LUKS passphrase:
With a old (2.6.25) vanilla kernel it works.
any ideas?
EDIT
Solved.
The Problem was that I had this line in my mkinitcpio.conf to get rid of the padlock-error-message at boot.
#CRYPTO_MODULES="aes_i586 aes_generic sha256_generic"
With kernel 2.6.27 there are new / more modules needed to open the LUKS encryptet root partition.
So I removed the line from mkinitcpio.conf and deletet the padlock modules in /lib/modules/2.6.27-ARCH before regenarating the initrd image.
Thanks to GerBra for the tip.

I'm not shure, but think ... yes.

I installed the system update to 10.7.3. After re-booting, my mail file was missing from the dock. Looked in applications and the mail application is missing. Any thoughts?

Thanks Paul; but, taking your suggestion didn't solve the problem. As mail is part of the OS, the updates don't have the capacity to reinstall applications; so, I had to reinstall the OS. I now have my mail back (although it didn't appear on the dock--I had to go to applications and activate it and then put it back in the dock. Thanks again for trying.

[Solved]Boot from USB HDD - Root device doesn't exist. Major/minor

My problem is that the kernel seems (or starts) to load, but then I get an error:
Root device 'UUID=1234 . . .' doesn't exist.
Attempting to create it.
ERROR: Unable to determine major/minor number of root device "UUID=1234 . . .'
You are being dropped into recovery shell
I found a few links on the web and in the forums, but nothing that really solved it for me. The solved ones usually downgraded the kernel. I haven't done that yet. I thought I'd try here first.
I have a 320GB USB HDD that I have been using to experiment with different linux distros. I have a few working successfully (OpenSUSE,Mint,Ubuntu,Debian,Fedora,etc). I'm very new at this but have been reading a lot and putting a lot of time into it. I have legacy grub loaded on the MBR and use the menu.lst on my openSUSE partition to boot everything. Because the partitions for some of the distros are so far into the disk I needed to create directories on openSUSE's /boot directory to contain the kernel and initrramfs files (like /boot/fedora). This seems to work for the other distros. I did the same thing for Arch.
So when I installed Arch I haven't used the bootloader section of the installation.
I'm using the 2011.08.09-netinstall-i686.iso Live CD.
I tried a few things including:
1. changing the HOOKS in /etc/mkinitcpio.conf
a. adding usb to the "HOOKS"
b. removing and adding autodetect
c. adding and removing "sata_sil" (although I'm not even sure if my device uses it)
2. changing the kernel line:
a. from using "UUID=" to (hd0,1) to sdb1.
b. added rootdelay=8
3. repartition all of my arch partitions using cfdisk from my Live CD and reinstall. I used gparted on OpenSUSE to do it the first time.
This may be connected. When I fdisk -l from the Arch Live CD I get extra data and an error for each of my arch partitions (and only my arch partitions):
Disk does't contain a valid partition table
When I fdisk -l from OpenSUSE I don't get the data paragraphs or errors about the arch partitions?
Here is my /etc/fstab:
# /etc/fstab: static file system information

I'm IN! Thanks everyone for your suggestions!
The arch system didn't like the identifier I was using for the root partition. By looking at the /dev/disk/by-id while the arch system was running, I could see what the system wanted me to call the partition. So after the system error'd-out and I was in the recovery shell at the [ramfs /] prompt:
# ls -lF /dev/disk/by-id > by-id.txt
# vi by-id.txt
I could have used any of the identifiers listed in the by-id (there were 3), by-uuid(1), by-label(1) or by path(1). I tried them all. I had to write these down by hand because it is a ram filesystem.
The article that finally got me there is:
https://wiki.archlinux.org/index.php/Pe … ice_naming
Anyway my openSUSE grub menu.lst ended up like this:

How to boot a desktop-PC into RT directly from harddisk (without floppy disk)

Hello,
we are using a normal desktop-PC as LabVIEW real-time target (ETS).
Unfortunately, we always have to use the floppy boot disk (created with MAX) in order to boot this RT-system.
Once we had a National Instruments PXI real-time system and there was no need for that boot disk to start the system.
So, why do we have to boot the desktop-PC from a floppy disk instead of booting directly from harddisk?
Or is there a possibility to boot the desktop system without floppy disk, just like the PXI-system?
Tom S.

Hi Daniel,
thank you for your reply.
I just checked again if I can boot the RT-system without the floppy disk, from harddisk only - but that doesn't work ("DISK BOOT FAILURE, INSERT SYSTEM DISK...").
Of course, the boot order in BIOS is set up appropriately to allow booting from harddisk.
And also, the complete software package was already installed on harddisk via MAX through the previously configured network connection.
Actually, it seems there is no boot loader installed on harddisk at RT-systems for desktop-PC's.
The boot loader has to be launched from the floppy boot disk and afterwards, the further boot program is loaded from hard disk.
Is there anyone who can boot a desktop-PC into RT without the floppy disk? And what do I have to set up in order to make it work for our system?
Thanks,
Tom S.

NOT as a cache, can i boot Windows 8 directly from MSATA 128gb on an Envy 4 1026tu..?

Can i install & boot Windows 8 directly from MSATA 128gb on an Envy 4 1026tu..? Not as a cache. I want to keep my existing HDD as extra storage. Can i clean install Windows 8 and boot directly from a 128gb MSATA on my Envy 4 1026tu? Could anyone please advise me if this could be done. Thanks!

Hi,
In theory nothing can stop you to do that. You have to disable the HDD before install OS on the mSATA. One important thing: The BIOS allows you to do that. I know Dell people have done that. At the mean time, the following article may help:

Good luck.

How to set system time from Terminal while booted from 10.6.3 server install disk?

I'm installing from a 10.6.3 server install disc onto a Mac Mini. However, the battery on this Mac Mini is pretty much dead, forcing the system time back to 1/1/2001. Through some research, this has created a problem in that I cannot move beyond the Welcome screen during setup of OS X server. It looks like the binary has issues with the system time being older.
But I'm stuck in that I don't know how to adjust the system time from the Terminal Utility on the boot CD. Can anyone help?

Hey, i just run in to something similar, tonight while trying to fix a computer.
The user set the time and date on his computer to 1998 and computer locked everything including time and date in system preferences, and his user account basicly making him from administrator to guest. he could not almost any program properly that required administrator privilages.
to fix this we used this comand in terminal " sudo date 201703162014 " todays time and date
20:17 03/16 2014
we tryed everything and this fixed in 2 seconds
ps: when you type sudo in terminal it whil give you a warning the improper use of this command is bad.... click continue.otherwhise you will not be able to execute the command.
thanks again for this post and have a great day

HELP! How can i restore/recover files from Bootcamp with Boot Failure - Missing operating system error?

Hi,
I am having a few problems with bootcamp on my imac. When i tried to move the bootcamp partition on windows 7 into free space, it crashed and turned off. Ever since i have had the error 'Missing operating system' and it fails to boot. I have some very important files on the bootcamp partition. Is it possible to recover these files or even to restore the bootcamp partition to it's original state? I do not have a backup of my bootcamp partition. Another problem i have is that ever since i tried to expand my macintosh HD partition into free space, when i hold alt while booting up (to choose which partition to boot like i normally do), the bootcamp partition has stopped appearing. This means that i cannot even boot the windows 7 bootcamp partition anymore!
So basically here are my 2 questions:
How can i restore/recover files from Bootcamp with Boot Failure - Missing operating system error?
How can i make the Bootcamp partition appear in Startup Disk and when i hold the option key while starting up my computer to allow me to boot windows 7?
Any solutions are very much apreciated!
Thanks!
I know that bootcamp (disk0s4) hasn't been fully deleted since it appears in disk utility (i cant do anything to it though)
And here is the error i see when i try to launch bootcamp (back when i was actually able to boot up bootcamp to the error screen)

WinClone 3 is OS X and saves Windows image it makes for restore - that should work but you will have to try and you would need to make a new image unless it also works with a native Windows system restore image. It is now supported and has come a long way.

Paragon Clone OS works and does disk-to-disk clone just like CCC you end up with two bootable drives. But does not work with your setup. It would let you clone and move your Windows install to an SSD or another disk drive though and be bootable.
During its clone process it checks for errors which is very helpful and lets you know - something CCC and others should adopt more of.

I wish for our/my sake you had re-read and rewritten the long 'story' and broken it into a brief list of facts we needed.
OS X
Windows
Backup (though external is much safer) and you want bootable OS X clones as well as TimeMachine

There are a number of things to do like chkdsk and others as well as Windows DVD to do automatic system repairs and find out why.
AppleHFS - the abilty to mount and read HFS volumes can be notorious.
I would rearrange and redo your storage setup and how you use the 4-5 internal hard drive bays.

Connecting directly from ECC 6.0 to a 3rd party system with out XI ?

Hi Guys,
we have developed soap-soap scenarios in XI and we are sending the data from ECC 6.0 -> XI ->3rd party webbased system.
Due to some security reasons we are looking for options of doing the same with out XI ie directly from ECC 6.0 to 3rd party system.
can somebody explain or provide the links for doing the direct connection and also suggest the advantages and disadvantages of eliminating XI completly from the design
any hep would be really appreciated
Thanks,
Srini

HI,
Yes, using standard Enterprise services from SAP you can communicate with 3rd party systems also,
Even you can configure the HTTPS communication with R/3 to 3rd Party system. For this you need to install the client Certificates and have to use valid User ID and Passwords.
http://help.sap.com/saphelp_nw04s/helpdata/en/3a/7cddde33ff05cae10000000a128c20/frameset.htm
http://help.sap.com/saphelp_nw04s/helpdata/en/e8/1f1041a0f6f16fe10000000a1550b0/frameset.htm
Disadvantage of communication without XI
1. XI provides the re-usability concept. i.e. if you have just R/3 to 3rd party and tomorrow you may need to add another 3rd party or sap system to communicate, then you just re-use the existing scenario.
But in case of direct communication is leads to point-to-point connection.
2. R/3 can't directly support to the open Standards, either you have to use ABAP proxies or RFCs to convert it to XML format. But XI is an Centralized Integration Platform with Open Standard. In current world, Openness is important.
3. XI has the Ability to communicate with other messaging systems/products may be JMS or any other 3rd party systems also which has the limitations with direct communication
4. Complex processes for communication possible instead of only sending and receiving (business process management) (connect e.g. asynchronous and synchronous steps, define complex communication scenarios)
Mapping etc possible to accomplish in Java. Platform independent Java components.
5. XI has Java & .Net support. which is not possible with directly R/3
Thanks

I recently upgraded my iphone to the latest IOS but my GPS seems to have a problem... I am unable to get directions from one point to another ... how do I solve this problem?

help! I recently upgraded my iphone to the latest IOS but my GPS seems to have a problem... I am unable to get directions from one point to another ... how do I solve this problem?

If using the built-in Maps app, directions are not available everywhere. Read here:

If that's your problem, download the Google Maps app.

HT5188 Nearly every time I buy a VPP app and download the spreadsheet there are multiple redemption codes that say that they are invalid! HOW can a code I am getting directly from apple be invalid!!!!!!!! Seems like your system has A LOT of flaws.

I have taken it back to the Apple store genius bar, but they say they don't see anything wrong. Well unless you use it all day and experience the problems when they happen, you wont see anything wrong. But there are lots wrong with it. But this would be the same store as I purchased the phone. And they backed up my old Iphone 4, but were not able to get anything to load back onto my new phone. So, I lost pretty much everything. But over time, some of my contacts have started showing up, although i am still missing over 800 of them.

I have been trying to work on my homework all afternoon, via NAU's blackboard system. I am continuously getting booted out of the system, with an error stating "Data execution prevention". How can I prevent this from continuing?

If you are wondering why you are not getting any responses, it is because you have vented a complaint without any details that make any sense or give anyone something to work on.
If you want help, I suggest actually detailing what has happened, with versions of software etc. Anything that would let us assist.
As a start I am guessing that you have not really got the hang of "How it all works". Firstly download the Pages09_UserGuide.pdf from under the Help menu. Read that and view the Video Tutorials in the same place. A good addition would be the iWork 09 Missing manual book and something to help you learn how to use your Mac.
If there are specific tasks you need help with:
