I tried to access files from my old hard drive that used to be in a Mac (which unfortunately isn't working anymore). I connected it to my computer which I am running debian gnome on. So my question is how do i access a mac os extended disk image. The disk is encrypted and when i try to open it it says that i don't have permission. I think its encrypted in AES 128 bit.

This is my specific solution to my specific problem. After updating to Squeeze from my prior Lenny distro (amd64 with whole disk encrytion using LVM2, dm-crypt, LUKS) everything went well - at first. I was duped like so many, thinking that all was well and I could remove the legacy-grub (aka: Grub1) and just use grub-pc (aka: Grub2). As soon as I removed the legacy-grub and rebooted my laptop, I was confronted with:
GRUB Loading stage1.5 GRUB loading, please wait..Error 15 At this point I wasn't sure if it was a Grub problem or a deeper encryption problem - especially after reading that some people had missing packages in Squeeze (lvm2, dm-setup, initramfs-tools, etc.)
Okay, the solution for me.
1. download and burn to disk: debian-live-6.0.0-amd64-rescue.iso[URL]..
2. scroll to and press enter/return on: text rescue
3. choose a root directory - for example: /dev/blah/root (I wrote down the list of possible /dev/.... for reference - this helped me remember where and what I had partitioned in Lenny)
4. choose: Execute a shell in /dev/blah/root
5. once in the shell, I discovered I needed to mount a few of those partitions that I had written down in order to get access to grub-probe, update-grub, grub-install, etc. You may not have to if your partitions are minimal. I you need to use other partitions, type (for example):

I have 2 identical disks originally configured as a pair for a server. Each of the disks has 2 partitions dev/sdb1,dev/sdb2. The sdb1 partitions I had configured as a raid1 mirror. The sdb2 partitions were non-raid and used as extra misc. Space. Further, the raid setup is also encrypted using dm-crypt luks. Now I want to redeploy each of the disks for new purposes. One of the disks i want to deploy exactly as before (keeping the partitions and content), however without being part of a raid array.
I've successfully deployed this disk into a new system and I am mounting the dev/sdb1 partition as dev/md0 because the disk is set to autodetect raid. Actually I am using cryptsetup and mounting with mapper. Can I get rid of the setting for auto detect on this partition without losing the data, or breaking the encryption? I just want to mount the partition as a standalone encrypted disk. Is it as simple as doing crypt setup luksOpen /dev/sdb1 then mounting it with mapper? Or do I need to change the partition in some way. Or do I simply continue to operate it as a 'broken' raid array?

I've been trying to load Debian with no success. Let me describe the issue:
1. I downloaded the iso image from the Debian pages. The md5sums match.
2. I changed the boot priority so the CDROM is accessed first.
3. Performed a cold boot and see a black screen that says Checking media [Fail]. I see this three times (HD is 4th on priority list) and then Mint loads.
Here is the odd part:
4. I can successfully load Arch from the cd/dvd drive.
5. I can also load Mint form the cd/dvd drive.
6. Cannot load Crunchbang from cd/dvd drive - same as when I try Debian.
I don't know how to proceed from here. I did erase my log files and performed another cold boot with Debian in hopes I might find some sort of error in them, but I really don't know what I am looking for. I saved the log files ....

I've installed Debian 5.0.7 on a partition of my hard-disk. Before I was using Slackware, so now I have in sda1 slack 13.0 and in sda2 debian 5.The problem is that Lilo can't find the ram disk image. I tried to insert in lilo.conf file the line "initrd=/deb5/initrd.img", but it doesn't work. I tried also to create from the installation cd an initramfs file and to make the link "/deb5/initrd.img" point to it.I've used the "lilo -v" command from slackware, so in / was /dev/sda1 with slackware 13 and in /deb5 was mounted /dev/sda2 with debian 5.

What i need is to mount several directories from any other partiton (or file system) as a new merge file system that can grow or decrease depending on the free space. As if it was a dinamic RAID,so i can work with huge files distributed over the partitions mounted.
Ejemp: /mnt/sda1/dir_raid1 + /home/dir_raid2 + /mnt/sda3/dir_raid3 ---> /mnt/RAID/
mhddfs and unionfs <---- are not the solution im searching (cant use huge files)

My partition table is completely screwed, although the data on the lost partitions hasn't been overwritten. I've been messing around with TestDisk for about an hour, but I still didn't figure out how to fix my problem.
Before the crash, I had 5 partitions:
And here comes the extended partition:
TestDisk can see all those five partitions. I can mark swap as Logical, but I can't do so with the 400GB NTFS partition - there is just no selection. Turning on "expert mode" didn't help. I have read about using sfdisk to fix partition table, but I don't think I'm able to do it by myself.
Here's how it looks in TestDisk:

And, here is my slightly modified sfdisk table dump:

I've filled sizes according to TestDisk's findings. First 3 partitions were OK, the problem lies in the extended partition holding 2 logical ones.

Can I create live disk using my hard drive installation? If yes then, can I restore the fedora from the live disk to the hard drive. I mean to say that from that live disk can I install fedora again in my hard drive.
Second question is, if I create the disk image of my hard drive( including ntfs & FAT32 partition) , can I restore it in a blank drive. If so , then can os will be restored also?
I need a FREE solution that can image an entire Luks system encrypted volume and the rest of the used HDD, the MBR and /boot partition. Note: MBR and /boot are not encrypted. Note 2: I want to be able to restore entire drive from image with only a couple of steps. Note 3: Destination HDD space is a factor. Image file must be compressed and the image file must be around 40 to 50 GB or less. The smaller the image the better.
I have used clonezilla live cd before but not for encrypted volumes. I know you can install it in Linux. But, I don't know how to configure it after installation. I would be very happy if someone could tell me how to configure clonezilla in Fedora. How to guides are also welcome. I have one more question. If I image the encrypted volumes and all the stuff I mentioned above while logged in to Fedora, and I restore the drive from the image, will the recovered drive still be encrypted?
I have installed ubuntu via the alternate installer, activating encrypted home directories, which in turn enabled to have encrypted swap partitions and disabled hibernation (suspend-to-disk). I understand the arguments for having an encrypted swapspace in these cases. However, I'd like to be nevertheless able to hibernate. Now that the system is already set up, I cannot change and completely encrypt my harddisk via LUKS+LVM as it is suggested in numerous places.Instead, I tried the following. I created two swap partitions (sda7 and sda: one being encrypted via cryptsetup, to be used as a 'real' swap (sda7). Another without encryption, which is not listed in /etc/fstab, so that it is not normally used by the system. I have then configured uswsusp in order to use sda8 as a resume partition:
[code]...
I have decided to encrypt the resume image - I don't care entering a password once every time I resume, it just shouldn't be at every boot. And this way, I can have hibernation without the uncomfortable solution of having my decrypted, open files on the disk as clear text. However, as sda8 is not 'mounted' when I want to suspend, I get the following error:
[code]...
When I try to suspend now, it works. The image seems to get correctly written to sda8. However, on reboot, the image does not seem to be detected and the system is not resuming. I end up with a fresh login screen. would be also to unmount sda8 upon resume, is this better done by entering a hook in /etc/pm/sleep.d or can I just continue in the wrapper script above by executing s2disk.unwrapped only by calling it (without 'exec'), and entering a swapoff line behind it?
Ive managed to screw up an encrypted disk experiment, basically at boot i get ask to enter my password which i lost.
Only a data partition is encrypted, the linux system is unecrypted.
However, the skip option thats presented that should work via S does not work. every key in input adds one * behind the password prompt.
The password prompt changes from white to red though. as if in the white phase you should be able to skip.
Im to lazy at the moment to swap the drive and comment the drive in fstab

OS: Debian unstable 32bit, kernel 2.6.32-2, grub 1.98 from late january 2010 (only have working net-access from work now, so I am grabbing information from memory). EXT3 and EXT4 support is compiled into the kernel along with chipset/scsi/sata support (not as modules), and I have tested to boot ext3 with it before proceeding. Prereq: my old disk started to have too much S.M.A.R.T errors, so I bought another one, put in a USB cabinet, added swap and ext4 partition/filesystem to it, and copied over all data from the old system to the new that was mounted at /dest using the command "find ./ -xdev -print0 | cpio -paV0 /dest". Swiched disks, so I now have the ext4 disk sitting at /dev/sda (partitions: sda1 => ext4, sda2 => swap), and booted into rescue-mode from cdrom, using /dev/sda1 as root with a shell on. After doing this, I performed the following commands:
mount --bind /dev /dest/dev
chroot /dest
modified the /etc/default/grub to instruct the kernel to boot using ext4, ran grub-install --recheck /dev/sda
ran update-grub to modify /boot/grub/grub.cfg (which looks as it should) After doing this, grub finds my partition and mounts it. It however stalls with the message: "warning: unable to open an initial console" and does nothing after this point. I have no ramdisk, but my old kernel booted fine from ext3 (and still does if I copy it to a ext3 partition), and since the ext4 support is compiled into the kernel - should I really need a ramdisk?
I can see from /var/log/messages error messages and weird crashes that the disk in my laptop is on the way out.

Does anyone know of software (either open source or commercial pay-ware) or a technique to do this?
View 1 Replies View RelatedI have an external 300GB (Toshiba) disk which I encrypted (using cryptsetup luksFormat) and then installed an NTFS filesystem on (need to be able to use it in both Linux and Windows - using FreeOTFE). The disk mounts fine in windows and on my Fedora 10 system it automounts.
I can manually mount it on the RHEL5.3 system, and gnome-mount gets as far as recognising that it is encrypted and asking for the key, but it doesn't then mount it - I then have to manually mount the /dev/mapper/luks... device.
Does anyone know how to do this - if it works in Fedora 10 it ought to be possible to get it to work in EL5.3 I'd have thought.
How can I get a LUKS encrypted partition on an external USB device automounted with r/w access for non-privileged users?
Background:
I just reformatted an external USB device with ext4. The only partition is LUKS encrypted. Now, when I plug the device to my computer, KDE notifies me and asks me to enter the LUKS passphrase. Then it mounts the device. Little snag here: Non-privileged users have read-only access.
My user is a member of group plugdev, but not of group disk, as this was discouraged several times, e. g. by Robby Workman. With non-encrypted disks regular users have read/write access, or can change the filemodes accordingly, as far as I recall (currently I have no more non-encrypted disks left to verify it...)
There are a lot of backup solutions, many scripts based of rsync. The problem is not a lot of them encrypt your data before syncing it. I have a USB hard drive and I want to backup my user folder /home/myuser/ to the external drive What software will allow me to create incremental backups which are encrypted with relative ease

View 1 Replies View RelatedI was running Ubuntu 9.04 Desktop on a headless Pentium 4 machine which is our file, mail, web & fax server. The two x 250GB SATA hard disks were in a RAID 1 array with full disk encryption. Ran the 9.10 upgrade via WEBMIN and it failed. I should have known then to copy over everything to a backup disk, but instead I rebooted.
On restart the machine accepted my encryption passphrase but promptly hung with a mountall symbol lookup error - code 127. So I can't start the machine to get at the disks, and using a Live CD is useless as it has no way to open the RAID array to get at the encrypted partitions. Although we have data backed up (as at last night) I'd hoped not to have to rebuild the entire server from scratch. But its looking bad.I have taken one drive out and plugged it into another machine (Hercules), and the partitions show up as /dev/sdb1 /dev/sdb2 /dev/sdb3.
If it weren't for RAID, I could open /dev/sdb2 the main partition) in Disk Utility and enter my encryption passphrase to get access. But RAID adds a layer of obstruction that I have not yet overcome. I used mdadm to scan the above partitions and created the /etc/mdadm.conf file, which I edited to show the 2nd drive as missing (rather than risk corrupting both drives). I activated the RAID array with mdadm, and cat shows:
Code:
root@HERCULES# cat /proc/mdstat
Personalities : [raid1]
md1 : active raid1 sdb3[0]
1815232 blocks [2/1] [U_]
[Code]...
I've been searching the web for hours but have yet to find someone with a solution to this situation. If anyone has a thought on how to access this disk I'd be pleased to hear from you. In the meantime I will start building a new (9.10) machine from scratch, without RAID, 'cos that's probably going to be necessary.
