Ubuntu :: Extract Data From Encrypted Home Partition Without Booting It?

Jul 17, 2010

Around six months ago (last time I reinstalled Ubuntu 9.10), on a whim I decided to check that option to "encrypt [my] home directory". I wanted to see what it was like. Mistake. Since then, I've been unable to figure out how to access the data in my home directory using any method besides booting the computer (usb drive, rip-out-and-stick-it-in-an-enclosure, etc.). Specifically, I find that shell script sitting there that tells you to run it in order to see your files, but it gives some kind of error. I also still have the code Ubuntu tells you to write down in order to decrypt your files.

Fast forward to this past week. I brought in the laptop to Best Buy for repairs to the hinge (the hinge! Ace Hardware could fix this problem! But I wanted to make full use of the service plan.), and I got a phone call a few days later, saying that it hit Best Buy's "No Lemon" policy. They were going to keep my computer and give me in-store credit toward a new one. Of course, I refused to pay ~$70 for them to back up my data for me; what could possibly happen to it when they were fixing a hardware problem?

Anyways, I pleaded with them for my hard drive back, and they said that they could ship the hard drive back to the store so I could get my data off of it. I'm planning on going in there with my external backup hard drive and an external enclosure and doing it myself at the counter (If they charge $70 to back up a Windows partition, how much more will they charge for an encrypted Linux one?). I don't want to embarrass myself by standing around and not being able to get into my own data.

Jun 14, 2011

It has somehow frozen my machine in so mighty way, that it apparently corrupted a directory with majority of my pictures , which now appears to be empty .My home lies on a separate partition, its encrypted aand using btrfs and I am using kubuntu 10.10. So, could anyone give me some clues how to unencrypt my home partition, that i could obtain an image of partition or whatever else usable for photorec to check for pictures?

Ubuntu :: Open Encrypted Home Folder While Booting From Usb?

Nov 17, 2010

My laptop running on ubuntu has been having some issues and it's giving error reports on logging in. Because I want to retrieve my files above all else, I installed ubuntu to a usb-stick and booted it directly from there. I can asses /media/myharddrive/home and there's a folder called lennard, which is the user account on my laptop. I can't open it however, because I don't have the necessary permissions. I'm afraid I encrypted it with an option that was standard to ubuntu. I have a 23-digit code right in front of me but I'm not asked to enter it so I don't know what to do with it right now.

Ubuntu :: Tried To Upgrade - Home Partition Still Encrypted

Jul 10, 2010

I have a dual boot WinXP / Kubuntu system. Recently, I tried to upgrade from 9.10 to 10.04. I have my Kubuntu partition set up with separate partitions for / , /home , and swap. Naturally, I wanted to wipe the slate clean, so I formatted / and left /home alone before doing the install. However, my /home partition was encrypted with the standard crypto that you get when you install. I just deleted the way in by wiping my / partition. Now all of my files are on my drive but encrypted. I do have the unencrypted passphrase given to me when the hard drive was first encrypted, so I am sure there is some way to get my files, but I am unsure how to apply it.

Ubuntu :: Recovering Encrypted Data From Corrupted Partition

Jul 20, 2011

I recently suffered a hard disk failure, meaning I had to replace the faulty device. After attempting to mount the old faulty hard drive using and external caddy, I got the following message... Unable to mount 144 GB Filesystem Error mounting: mount: wrong fs type, bad option, bad superblock on /dev/sdb5, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so

I'd like to attempt to recover what I can from my /home directory but unfortunately I use encryption (although I do actually know my pass phrase). What procedures and software can I use to try and recover data from this drive?

Ubuntu Security :: How To Recover Encrypted Home Partition

Apr 26, 2010

While setting up my laptop on a new hard drive (a bad mobo caused writes which pretty much rendered teh old hdd unusable) I was asked if I wanted to encrypt my home partition.

I've been wanting this for several years - even going as far as trying to get a copy of CheckPoint. That's waht my organization uses on all Wintendo laptops and is required.

In any case, I said "yes" and am happily using my laptop with an encrypted home partition. I'm assuming based on this - [URL] - that it is using EncryptFS as the scheme.

if I were to misplace my laptop, how easy would it be for a forensics team to retrieve my data. Let's assume I have a fairly strong passphrase, such as BisZumBitterenEnd3. [URL]

Ubuntu :: Encrypted /home Partition And Running Out Of Space?

May 26, 2010

I have an Acer Aspire One, Model ZG5 (also known as the 110 with 8GB SSD) which originally came with Linpus Lite installed on it.

I previously had 9.10 installed which was great, but I've done a fresh install of UNR 10.04 since I had a full /home partition and wanted to set up with more space.

This time, I opted for a larger /home drive (~4GB) and also to have it encrypted, which is a good idea for netbooks given their portability (and I have no idea why I didn't do it before!). Since I had very little space on my 8GB drive (if I wanted a larger /home) then I installed /home onto a separate partition, which is located on a 16GB SD card which lives in my machine permanently.

Installation was a breeze, and encryption seems to work fine. I have verified it and it seems to be working. However, I've now hit two related problems - one of which is to do with Thunderbird, and one which is an issue with the encrypted /home drive.

Firstly, I have a large gmail account which I like to replicate offline in Thunderbird (am using v 3.0.4). My online gmail tells me that I'm using 1.4GB of data space online. Using the old T'bird (v2.whatever) my offline T'bird storage was approximately the same size. This is not now true of my current offline storage file size, which is showing at 3.2GB for the same data. I started with a clean slate, just installing T'bird, setting up my account and then leaving it to download all data from Google.

Anyone know why this offline size is so much bigger than the online storage size or even the previous offline storage size?

Secondly, the encrypted /home drive. Given that I needed I put this on a separate card and partition, I had hoped to escape any issues with not having enough space. However, my system is now telling me that /home is out of space...

Specifically, I can see that I have used 3.6 of my 3.8GB storage for /home. This is due to the large size of my offline storage folder.

As I see it, I need to do one of two things (possibly both) - reduce the size of my offline e-mail storage, and increase the size of my /home partition.

Reducing the offline storage will be about finding out why it's so big in the first place.

However, if I wanted to increase the size of my encrypted /home file how would I do this? I have used gparted to make additional space after it - so I could increase the size if it's possible, but I am a little concerned.

If I just increase the size of the partition, would this work? Are there issues with the fact that it's an encrypted partition? What should I be aware of if I wanted to increase an already in-use partition, and how should I best go about this?

Do I need to do it from a live USB image?

Ubuntu Installation :: Reinstall With Encrypted Home Partition

Dec 17, 2010

I'm wiping out / on an Ubuntu box but want to keep everything in /home/, which is mounted on a different partition. Using Code: ecryptfs-unwrap-passphrase ~/.ecryptfs/wrapped-passphrase I have unwrapped the passphrase, resulting in a ~25 character alphanumeric string. Is it possible for me to install from a disk and give the installer the (current) passphrase so that it will automatically mount my home directory?

Ubuntu Security :: Recovering Data From Corrupt Encrypted Partition

Feb 25, 2010

I have recently recovered from an HDD failure on my Drobo. One of the disks died and corrupted the entire array (which is not supposed to happen). I have since managed to copy the data off onto smaller disks and after replacing the failed drive, have copied everything back.

Now that im up and running again, i was wondering how this situation would play out on encrypted disks, or in the case of a drobo a large encrypted partition (as you cannot encrypt the entire array).

Would i still be able to recover the data if i were to encrypt it? It is a 4.2TB array, and i assume that I would need to copy the data in its entirety to recover it, so using multiple smaller disks would be out of the question right?

OpenSUSE Install :: Encrypted Home Partition Automount?

Jul 24, 2011

First off I'm new to the openSUSE community and would just like to say So, to the issue at hand. I recently switched to openSUSE 11.4 from Debian. I noticed the setup didn't have an option encrypt the home folder like it does in Debian, so not being aware of any other way to encrypt it, I created a new partition, backed up my current home directory, created a new partition and mounted it as home before copying in the contents of the backup to the encrypted home partition I created. Now of course it is askingme to put the crypto password in at each boot, which isn't ideal because it's a family machine and no-one would remember the password but me. Is there any way of being able to automount the encrypted partition without having to put the key in every time? Or better yet an encrypted home folder that doesn't require the key to be put in on each login (as in Debian) without even using a dedicated partition.

OpenSUSE :: Delete Files On Data Partition Slow Because Trash Is Located On Home Partition?

Aug 18, 2011

KDE 4.6 - opensuse 11.4.

I have a separate ext4 partition which contains all my data (music, movies, etc). When I delete files from this partition it is very slow because it copies files from my data partition to the Trash folder in my home partition. How can I avoid this? Can't the trash be configured so that it uses a trash folder in each partition instead of copying files to another partition (which is slow).

General :: Windows - Using A Home Partition That Already Has Data?

Jan 24, 2010

I want to install Ubuntu side by side with Windows. I have a big NTFS partition that has a folder with the same name as my username (let's say "joe"). Inside "joe" I have my personal files. Outside "joe" but still in the partition, there is random stuff that doesn't really belong anywhere, or now useless programs that I had to install there because the main Windows partition ran out of space. If during the Ubuntu installer I choose to use that partition as /home and make a user called "joe", will everything work fine?

Fedora Installation :: Setup Dual Bood Data Partition And Move /home?

Feb 21, 2009

I have just spent dome time using gparted to sort out my partitions. I have a vista partition, a fedora one and a big chunk of unallocated space I wish to use as my data drive.

I want to move my ~ folder to the new partition and have windows/vista access the folder and write to the Documents, Downloads folders etc.

What is the best format to use?

Also I plan to start backing up my partitions to a server, for instance using g4l to save a linux image (maby a windose one too). Is there any benifit in keeping all the hidden files (ones starting with period '.') i.e moving the whole ~ folder or would I be best off leaving the ~ dir and moving the folders I know i use such as ~/Downloads, ~/Documents etc?

And how should i preform the move of all these files? 'mv'? do i need to add any special options?

Ubuntu :: 10.10 - How To Recover Encrypted Home

Nov 22, 2010

Dummy me let root run out of space because I didn't know to use logrotate. I was able to compress the system logs but not before the damage was done me thinks; now the computer is unbootable. I booted from a LiveCD and got my old partitions mounted under /media/oldroot to try and recover files; however, I forgot that I had encrypted my home. I found [URL] and was following it; however, I seem to run into a bunch of path issues after I chroot.

The chroot command returns:
bash: groups: command not found

The su command returns:
-su: cut: command not found
-su: getent: command not found
-su: expr: command not found
-su: groups: command not found

Finally, the ecryptfs-mount-private command returns:
-su: ecryptfs-mount-private: command not found

I have separate partitons for /, /home, /tmp, /usr, and /usr/local and bothered to mount the first 2. (If only I had been ambitious enough to create a /var). I was running Ubuntu 10.10.
