Ubuntu Security :: 10.04 Installed - Home Directory Not Decrypting
May 5, 2010
I have a major major issue with an encrypted /home directory. I had used encryption on my home directory when I installed 9.10. However, I had not noticed that I needed to store the automatically generated passphrase anywhere. Now, upon installing 10.04, my home directory would not decrypt. I checked my .encryptfs directory and the wrapped-passphrase file is GONE. I only have the Private.sig files from my 9.10 installation and of course know the login password I binded to the passphrase. I can see my .Private directory with filenames starting with ECRYPTFS_FNEC_ENCRYPTED. Now, my PhD thesis which I have to deliver in 2 weeks is in there. With no backups. How to recover my data. If no 'normal' method would work, is it possible to use a brute force attack and feed it my login password?

Ubuntu 10.04 LTS Ran some updates,finally got around to rebooting. When I rebooted, It came up with Some errors about missing files. Came to discover my home directory was not decrypted. I simply had a readme file that said to run "encryptfs-mount-private". When I do it doesn't tell me the passphrase is incorrect, it tells me
Code:
Inserted auth tok with sig [xxxxxxxxxx] into the user session keyring You do not own that encrypted directory and I do own it. If I put in a different pass it tells me it's incorrect, I'm logging in fine, but my home directory is remaining encrypted.

I recently installed Ubuntu Linux and did not encrypt the home directory during the install. Now I want to encrypt my home directory, or even better the whole hard drive.

I'm an absolute beginner at encryption. gpg and keys still have me somewhat mystified, so please forgive me if the following seems like a stupid question. I'm looking at encryption software for my smartphone. I've found a Java program called TinyEncryptor that uses the TwoFish algorithm and claims to be a shell for the "Legion of the Bouncy Castle" libraries. It just uses a passphrase; there are no keys involved as far as I am aware.
Naturally, I would like to be able to decrypt files on my desktop that I've encrypted with this program. So far, I've not had any success with finding one.

I have a computer running Fedora 14 and when I installed it, I chose to encrypt the drive.
I've recently changed the way I have things set up and don't want the encryption any more. From what I've read there is no way to simply and easily remove the encryption, so what I would like to do is input the pass phrase remotely.
so, Is there anyway I can type in the pass phrase remotely, or remove the encryption?

lets say I install Ubuntu 10.10 on my laptop. I check the box that says encrypt my home directory, and my password is a randomly generated 10 character password using uppercase and lowercase letters and numbers. The next day my laptop gets stolen or something. How hard would it be for someone to decrypt the home directory if that were the goal?

I had a student, and she has done some work on her account on my lab computer, but has left the country and is un-contactable.
I have full administrator privileges for this machine, and it is running Ubuntu LTS 10.04
She has a folder which was copied from a windows formatted external hard drive (Probably NTFS) onto her home partition on my machine.
I can open all of her files, except for those in this folder.
As I see it the problem is either something to do with the permissions of the files (coming from NTFS), or some kind of Ubuntu security that I am unaware of?
Here are my attempts to open it code...

i need to find a way to securely authenticate a decryption mechanism of some sort where the authentication is provided remotely without any user-interaction. Right now i have a number of boxes that all inform a central server when they are online. When they do this an OpenVPN connection is set up between them and the server.
However, i have been given the task to ensure that the scripts involved in this process are encrypted by default. This requires some form of self-decryption, which to my mind kind of goes against the whole idea of encryption/authentication in the first place. I need some way to leave decrypted the bare essentials required to boot a box and securely connect to the central server automatically. Then the server would automatically send a key/passphrase and the rest of the files on the box would then be decrypted on the fly.

Running Ubuntu 10.04 I logged into (sudo?) (root?) using:
Code:
sudo -s
and then entering my password.
I navigated into the home folder and viewed the long listing of it's contents using:
Code:
root@host:~# cd /home; ls -l
total 4
drwxr-xr-x 65 uname uname 4096 2011-05-22 17:14 uname

Not using filename encryption when you create a new encrypted folder is easy, but how to disable it in the home encryption that is automatically set up by the Karmic installation CD?

I am running ubuntu 11.04 I'd like to encrypt my home folder. - how can it be done, without creating new user/starting from scratch. -I'd like to keep all the files and desktop settings - the only change should be that the folder is encrypted now.

Sometimes you get more than you ask for and in this case, I did: I had no idea (had the computer for a few years now) that I was running a dual core 64 bit machine. The silly thing is that I have 32bit Fedora 11 on it, 32 bit versions of all my installed software...etc., etc. Am I able at this point to salvage anything or is it best to just back up the home directory and then do a reinstall?

I have an interdependent collection of scripts in my ~/bin directory as well as a developed ~/.vim directory and some other libraries and such in other subdirectories. I've been versioning all of this using git, and have realized that it would be potentially very easy and useful to do development and testing of new and existing scripts, vim plugins, etc. using a cloned repo, and then pull the working code into my actual home directory with a merge.
The easiest way to do this would seem to be to just change & export $HOME, eg
cd ~/testing; git clone ~ home
export HOME=~/testing/home
cd ~
screen -S testing-home
# start vim, write/revise plugins, edit scripts, etc.
# test revisions
However since I've never tried this before I'm concerned that some programs, environment variables, etc., may end up using my actual home directory instead of the exported one. Is this a viable strategy? Are there just a few outliers that I should be careful about?

I just installed the testing version of Debian with the option to setup encrypted home directories. I used a passphrase that I now want to change to something else. How do I do that?

In my opinion there should be a tool installed in Ubuntu by default which lets the user easily encrypt his home folder. One is given the option in the installed, but if one decides to encrypt his folders afterwards that's quite hard to achieve.

I have a dual boot at home with W7 F15. The Fedora drive is encrypted because that's where all my important stuff is. On the rare occasion that I do boot into Windows, I wondered if there would be any way of accessing my encrypted Fedora drive? Is it possible to decrypt and mount from Windows?

I have a dual-boot macbook with an OS X partition and an ubuntu partition. When I first installed ubuntu, I changed my home folder to my OS X home directory to synchronize all my files from both. My home directory is now /media/sda2/Users/username/. In a regular home folder, the icons for Documents, Music, Pictures, Movies, etc. are different (not just with emblems, but actually different icons). But when I changed my home folder, these subfolders' icons stayed the same as regular folder icons and I can't figure out a way to change that default setting. I know how to change the icons for each folder manually, but these changes don't appear everywhere (i.e. nautilus, places, etc). Furthermore, every time I change my icon theme, I would have to manually reassign icons for these folders. Is there a way to globally change the folder icons for these folders?

I need to specify a different path to home directories on a particular server than what LDAP contains for the users, besides using a symlink. E.g. "/Users/jdoe" vs "/home/jdoe" I don't want to change the actual LDAP attributes, just want a particular server to point them in the right direction (Ubuntu 10.04).
I'm assuming it's something I could probably set in pam configurations?

When I login using "adah" username in TELNET I am automatically directed to my home directory at location "/media/disk-1/home/adah". But when I use SSH to login using the same username I get the following message Code: Could not chdir to home directory /home/adahaj: Permission denied

I have a secondary disk which holds a /home directory structure from a previous install of Linux. I installed a new version on a new primary drive and mounted this secondary drive as the new /home. Problem is, even though the users are the same names and I can access the home directories for the users, I cannot login directly to their home directories, as I get the following error: -
Code:
login as: [me]
[me]@[machine]'s password:
Last login: Wed Jan 6 18:34:33 2010 from [machine]
Could not chdir to home directory /home/[me]: Permission denied
[[me]@[machine] /]$
Now, since the usernames are correct and the users are in the passwd file with the correct home directory paths, could it be user ID's that are different or something else? It's not as though I cannot access the home directories for the users, simply that I cannot log directly into them from a login prompt.

Is there anything special about a home directory before users' home directories are stored there, or is just as typical as any other "empty" folder?Let me just cut to the chase, but please no ear ringing about the folly of messing around as root, particularly with directories at root level. I know it's considered stupidity, but I deleted my home directory.
Is there an easy way to restore a working home directory? I tried copying /etc/skel under root, but I'm not sure what a home directory should look like once it has been restored. Besides . & .., there were .screenrc & .xsession in my home directory when I copied /etc/skel. Are these files suppose to be in "/home" or "/home/~" or both?

I have Ubuntu Karmic. I chose to install with an encrypted home directory. Recently I got a warning that I only had 2GB of drive space left. This is mostly because of my videos. So I went and bought a new hard drive and partitioned it and made 1 ext4 partition and copied my videos all to the new hard drive. I added a line in my fstab to mount the new hard drive to ~/videos, but when I reboot the computer, there is a screen saying something like "error mounting /home/me/videos, press S to skip or something else to reboot". If I press S to skip, then when my system comes up there is a video directory but it's empty because my other hard drive didn't get mounted. I can run sudo mount /dev/sdb video/ and it will mount fine and I can see all my videos, so why can't fstab mount it? Does this have something to do with my encrypted home directory?

I'm using Mac OS X's Terminal.app shell to compile and run Fortran programs. One such program resides outside of my home directory (it is in the Applications folder, which resides on my hard drive but seems to be outside of my home folder). How can I navigate into this directory using Terminal.app to run the programs that reside there?

I have read that to improve security in Ubuntu a good fix is to make the /home folder tree non-executable by default. This would mean that malware could not run in the /home tree without changing the setup.Is this a viable change, or is it just icing on the cake, any one any thoughts on this.

So I have a jpg image file that was encrypted using 256-bit AES, and I know the passphrase. That is ALL the information I have about the file. Is there a way (under Ubuntu, preferably but not necessarily on the command line) to decrypt this file?

I recently popped in the CD that came with one of my textbooks from school and figured I would be able to rip it pretty easily, but guess what? Too my surprise I find that each chapter of the textbook has it's own PDF file and that each one is encrypted. Is there anyway I can decrypt the PDFs and merge them all into one?

I recently bought a bigger drive for my laptop which had an encrypted LVM PV on it that I wanted to get rid of for performance reasons. I hit a few snags with the migration and documented it on my blog.
Fancy reading it? Go to my blog post about upgrading harddrive with encrypted LVM.
