Fedora Installation :: Install F13 With Old Encrypted /home?
Jun 23, 2010
I encrypted "/" and "/home" during boot with F12. Now I'm trying to install F13. The problem is it will not allow to specify /home as the mount point. It will take /home and not complain but when I get back to summary there is no mount point, just blank. When I entered the passphrase it didn't complain so I think that is okay. The / dir I said I wanted to format, so it accepted the / mount point.
I tried to go ahead and install F13 anyway thinking it may figure this out. However it didn't use my /home but created a new /home.

After update to 11.4, I would like to regain access to my encrypted home that I left intact. Both user.img and user.key files are there, but when I create the same user again in YaST, it does not recognize their presence and it asks again for size of the image. I am afraid it will just overwrite the old image. I do have full backup of hte data, but since its 150GB, I would rather not have to transfer it again.
How can I remount my old encrypted home?

I am trying to open an encrypted home directory from opensuse 11.2 with opensuse 11.3. This means i have a user.img and a user.key So far i have done:
losetup /dev/loop3 user.img
cryptsetup luksOpen /dev/loop3 home
Enter passphrase for /dev/loop3:
No key available with this passphrase. At this point it will not accept my passphrase.
A luksDump reveals:
cryptsetup luksDump /dev/loop3
LUKS header information for /dev/loop3
[code]....
When i try to use the key file, i get:
cryptsetup luksOpen /dev/loop3 home --key-file home.key No key available with this passphrase.

I am having a problem setting up an encrypted home directory with openSUSE 11.3. I used Yast User and Group Management to edit an existing user to encrypt the home directory and the user.key and user.img files were created in the /home directory. I tried it out and logged in as user and created a new file. I logged out and logged in as a different user and was able to see the newly created file in the first users home directory.
I figured I did something wrong so I went back to Yast and deleted the user. I deleted the /home/user directory using file manager su mode. I tried again to create a new user with an encrypted home directory using Yast and now when Yast tries to write the changes I get an error: "pam_mount is already setup for user. Use --replace to replace the
existing entry." I do not know how to proceed from here except to try with a different user name as I do not understand what the error message means and what command to use --replace with.

I'm guessing that a file is created as a loopback device and encrypted (using LUKS?)
What is the mechanism used at user login to decrypt and mount the encrypted $HOME and to re-encrypt it at logout?
I confess an ulterior motive here - SWMBO has recently got her hands on an Acer Aspire one running Linpus Lite and there's absolutely no security on it
Personally I'd dump Linpus and put on openSUSE but it's her box and she likes the simple interface that Acer have supplied so maybe I can set up the encrypted $HOME as YaST does for openSUSE if I can find out what to do.

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.

I'm still running 9.10, but now would like to install 10.10. Now I'm wondering about how to keep access to my encrypted home folder.
Usually, I don't do an 'upgrade', but a fresh re-install. I have a separate /home partition, so normally this works just fine. However, my home directory is encrypted (a feature that was introduced with 9.10, I believe).
So, if I whack the system partition and do a fresh reinstall there, will the new install still be able to read my home directory? Or do I need to save a key file from somewhere?

I'd like my /home partition to be encrypted. Does this need to be selected during installation (I don't remember seeing an option) or can it be enabled after installation?
How stable is this with ext4 on Fedora 11?

Recently installed Fedora 14 64 bit on a hardware RAID 1 from distro DVD, and set up an LVM with an encrypted /home partition. I now need to resize (enlarge) the /home partition and have not been able to do it due to system-config-lvm telling me:
"Logical volume is not mounted but is in use. Please close all applications using this device (eg iscsi)"
I have tried doing this logged in as user, and also as root. I've tried with a Live CD, but an additional problem there is that the Live does not recognize the hardware RAID and tells me I have the same /home partition in two devices, which are the two disks in the RAID array, and refuses to resize.
I found this link:
< https://help.ubuntu.com/community/Re...ptedPartitions >
which details a rather complex process to achieve what I want, but I am wondering if there is an easier way ?...
PS... forgot to mention I have been able to successfully resize all other LV's within the LVM, so I am assuming it is the encryption that is causing the problem....

I would like to give a few students a preconfigured Ubuntu USB stick with certain apps. I also encrypted the home folder in case of loss.
With TrueCrypt, cloning an encrypted container would be a big no-no because any one could just backup their header with a known pw and use it to decrypt anyone else's container due to each container using the same master key. I assumes the same applies to home folder encryption, yes?
Is there a way, other than creating a new user with home folder encryption, of forcing a master key change?

I tried upgrading to 10.04, and now when it boots it just goes into a grub2 terminal and doesn't display a boot menu. I tried re-installing grub2 from the live cd, but that didn't do anything. I figured if I've hosed the last install I'll install from scratch, but I can't even access my files from the live cd! I did a bit of searching and everyone seems to just encrypt ~/Private, whereas I've encrypted the whole home directory. So much for security... In the live cd, it has a readme.txt and says to type "ecryptfs-mount-private" to access the files, but it just gives the error "ERROR: Encrypted private directory is not setup properly". What do I do?

I purchased a larger hard drive to upgrade my HTPC running MythTV and a Samba file server. I put the old hard drive into an e-SATA enclosure and can still boot to it to access my files, but I can't seem to mount it correctly under the new installation to copy over my files even though I have the mount passphrase and encrypted filenames key.I have tried using this howto, but I run into problems with the encrypted filenames.This is how I'm doing it. I replaced the actual key data with A's and B's to protect my keys:
Code:
$ sudo -i
# ecryptfs-add-passphrase --fnek

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?

I have installed Kubuntu 10.04 x64 from scratch using the alternate installation CD and unfortunately I'm experiencing some serious troubles. Everything worked fine, installed packages, moved my backed-up data to my encrypted /home partition - until I rebooted. Usually I reboot the system right after the installation process to see if the boot process shows any errors, but what can I say, seems like I forgot to do it this time .
The problem is that the boot process just "hangs" right before the login window should disappear. By "hang" I mean dead: no switching to virtual terminals, no CTRL-ALT-DEL - the system just freezes.
I'm quite familiar with doing things shell-wise, so I started the "Rescue Mode" from the alternate CD and was able to mount my root partition.
Problem #1: No faulty log entries whatsoever: dmesg, boot.log, messages etc. all looking fine - except Xorg.0.log. I suspect the proprietary Nvidia drivers to be the culprit here, because what I'm getting is: "Caught signal 11 (Segmentation Fault). Server aborting"
Running "startx" as root from the rescue shell gives the same results: complete system freeze. "Looks like a reinstallation candidate, let's just backup my data" I thought, which brings us to
Problem #2: I can't mount my encrypted /home from the rescue shell. The exact steps involved are:
Mount my root partition and chroot to it. Issuing "ecryptfs-mount-private" gives the following error message: "ERROR: Encrypted private directory is not setup properly" Becoming my user "su - faulty" and trying step 2 again yields the same results. I feel like I'm almost there: I'm executing commands in my root environment, just can't seem to access my data which I'd like to backup before doing a clean reinstall. Any thoughts?

I want to create a user with a encrypted home folder. I tried "sudo adduser --encrypt-home username" but I get following error "adduser: Could not find program named `ecryptfs-setup-private' in $PATH". I installed the cryptsetup package but without result.

I had errors pop up when I tried updating my 10.10 to 11.04 so I ended up having to do it from a Live USB which installs it over everything (fine by me).Unfortunately I forgot I had an encrypted /home directory. So various messages and stuff came up when I tried to log in.nfortunately I don't remember what my encryption passphrase is offhand, so I moved it to a slightly different folder name and had to have a new directory created for my username.It's still there, but how can I try to open it trying the various versions of the passphrase I think it may be? Can I double-click it and try?Also, in the future what is the best way to handle a "fresh" install that I want to connect to my encrypted /home directory?

I just tried reinstalling ubuntu 11.04 from the live disc, installation went well but afterwards I cannot get access to my home directory which is encrypted and I stupidly forgot to note the mount passphrase. is there anything I can do? where would the mount passphrase be stored from the previous installation and is there any chance of recoving it. Home and the root are on the same drive and the installation did not format the drive.

Is this irrelevant if you are using the kde install disc? I want to use a encrypted filesystem. I would think since I am using kde that I would have a graphical interface.

I am running Folding with the multi-core High performance client and would like to set this to be a service rather than have to run it by hand, so to speak, when the machine is booted.
How do I go about setting a service up for this.

I need to disable my encrypted home directory because it prevents me from logging in with my fingerprint scanner when I first boot up. I'm running kubuntu 9.10.How do I do this?Also, how would I revert back to it being encrypted if I decide to not use the fingerprint scanner for initial log in anymore?

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.

I have choosen to encrypt Ubuntu 10.10 during installation (no alternate installation). After some time of working properly I get following error message after I put in correct password :
"Could not update ICE authority file /home/surf1/.ICE authority"
When I click "ok" following error message is shown :
"there is a problem with the configurationserver (/usr/lib/libconf2-4/gconf-sanity-check-2 finished with status 256)"
When I click this "ok" next error message appears :
"Nautilus could not create following necessary files : home/surf1/Desktop,/home/surf1/.nautilus"
After I click here ok nothing else happen anymore and I get not access to my account and so to my data.

I installed Ubuntu Server because I want to learn Linux and I want to learn about servers. I did a newbie tutorial and then shut down. When I booted up today, the files in my home directory were replaced by Access-your-private-data.desktop and readme.txt, but I have no idea why. I followed the instructions in readme.txt and typed ecryptfs-mount-private. It told me
INFO: Your private directory has been mounted.
INFO: To see this change in your current shell:
cd /home/rmob
But if I do ls /home/rmob, it still shows me Access-your-private-data.desktop and readme.txt instead of the files I created there yesterday. Every time I reboot, it tells me
keyctl_search: Required key not available
Perhaps try the interactive 'ecryptfs-mount-private'
If I try ecryptfs-mount-private again, it still tells me it has mounted it, but still just shows me those same two files. Googling about this tells me this means the directory got encrypted somehow. I tried typing touch ~/.ecryptfs/auto-mount which I found in this tutorial, but it didn't make a difference and I can't find any other solution anywhere.

I'm recently switched my work laptop from running winXP to runing karmic. I'm still at the stage of getting my various bits and bobs working correctly. One of these I (may) have a problem with is backup's. I've ran backuppc on a ubuntu 9.04 box in the attic for the last year or so and I've been backing up my laptop to that. But since the switch, since I have an encrypted home dir, what is being backed up is the encrypted files. First, can I recover these if needed (I kept a copy of my passphrase), or can I get backuppc to ssh in as me with my home dir mounted correctly?
Backuppc is using rsync over ssh I've been using linux on and off since about redhat 5.0, so I'm not afraid of the command line or vi

I recently did a clean install of Ubuntu 9.10 and when I did I chose to have /home on it's own partition and have it encrypted. The more I think about it the more I regret this decision. What if I want to switch distros down the road? What if I have to boot from a live cd to back up files? Is there a way to "undo" the encrypted home folder permanently? I don't mind having it on it's own partition, it's just the encryption that makes me worry.

I recently installed Ubuntu Karmic on my netbook (I tried netbook remix but preferred the look of the regular desktop edition). When during installation, the option to encrypt the home folder appeared, and being mildly paranoid I thought, "sure, why not?" (I must warn you that I am a new user with little technical knowledge other than what I have managed to gather in a semi-passive manner over the past couple of months). The problem is, I (try to) backup my data weekly, and so today I gave it a shot (I got the desktop edition a week ago). I have encountered the following problem.
I backup my system following (approximately) the instructions at [URL] for Backup The exact command I enter at backup is:
sudo tar -cvpjf 2010.02.13.tar.bz2 --exclude=/proc --exclude=/lost+found --exclude=/sys --exclude=/mnt --exclude=/media --exclude=/home/dan/music /
(I exclude my music folder as it is huge and I already have it all in several other locations) When I executed this command all ran smoothly for a while, however it soon began backing up the directory /home/.ecryptfs/dan/.Private At this point, it started backing up the huge number of files in this directory. I assume these are encryption keys? Forgive my ignorance... Anyway, it took several hours going through this folder, and finally bzip gave up, complaining of excessive file size:
bzip2: I/O or other error, bailing out. Possible reason follows.
bzip2: File too large
Input file = (stdin), output file = (stdout)
I assume that excluding the encryption keys and such from the backup would be a bad idea: I guess that if I did not restore the relevant directories along with my home folder, it would be inaccessible? Is there a way to avoid backing up such a large amount of data?

During the installation of Ubuntu Karmic, I picked the option that encrypts my home directory.
A few questions:
(1) Shortly after installation, I was asked to run a command to print a key necessary for data recovery from a rescue CD. I didn't run it at the time and am now looking for the command to run. What is it?
(2) I think I read somewhere that this also encrypts swap. Great. Correct me if that's wrong.
(3) If I suspend the machine, is my home directory encrypted? That is, if I have this on a laptop and travel with the suspended laptop and someone steals it, are my data safe, or not?
(4) I assume the weakest point in the system is my relatively short login password (but I think the install tests it and found it okay). Is there a recommendation how long this should be?

I ran fsck on the wrong partition (which was mounted) and in my haste blew up the file system on that partition. Now here's the kicker, I had 450Gb of data and documents on that partition that was in an encrypted home directory. So the long and the short of it I ran fsck again and I was able to recover all the files, and they are now residing on a Lost+Found folder on my hard drive.I have located the encrypted files, but I don't know what to do with them.
