Ubuntu :: Mount Encrypted Ubuntu Partition Onto Gentoo
Mar 8, 2010
ive recently switched to Gentoo as my primary OS - the only problem im having so far is getting my ubuntu partition to mount, aparantly it is encrypted, although i cannot remember ever doing this. It is an ext4 filesystem. When I do
[code]...
It mounts, but when I cd to /media/Ubuntu/home/dean all I see is a blank README.txt and Access-Your-Prive-Data.desktop files. Is it possible for me to mount my ubuntu partition to be read / written to in gentoo? If not, how do I go about removing the encryption? (I still have access to the ubuntu install)

Times like this Ubuntu makes me want to pull my hair out. When I enter my pass on the login screen, it brings up a "Could not update ICEauthority file" error and then goes to a black screen. I've tried to fix this problem for the past 2-3 hours (searching google, these forums, etc) and at this point, I just want the data off my drive so I can restart with a fresh install of Ubuntu. I used the "gsku nautilus" command to mount the disk from a Ubuntu Drive boot, but it's not letting me have access to the encrypted drive. Does anyone know of a work around for this?

I'm having a problem auto-mounting a new luks partition. I have crypttab and fstab entries. I already have my primary encrypted partition (root) mounting at boot (from the install), but after creating this one manually, it does not open on boot. It auto-mounts when I run the following command manually after boot: sudo luksOpen /dev/disk/by-uuid/<uuid> mycrypt
/etc/crypttab entry:
personalcrypt /dev/disk/by-uuid/a1af5b7b-db58-4690-b586-b74407795e2c none luks
/etc/fstab entry:

I used Ubuntu for years now, but since the latest decisions got public I deceided to try something new: Fedora. I installed the system as a dualboot,Ubuntu and my old data. Because Fedora got installed inbetween of two partitions,ad to do the partitioning manually. I just made one partition /dev/sda4. During the installation process I got asked about the password for my /dev/sda1 partition. Of course, I entered it. So far so good.Now, everytime when I boot, the boot process stops and asks me for the password of the /dev/sda1 partition. However, the boot process does not go on, unless i press STRG+C.After the log in, I can also not access my data, by entering the password (GUI).The only way I can acces the data on that partition is:
Code:
su -
cryptsetup luksOpen /dev/DEVICENAME luks-fedora

I encrypted my /home partition in my last installation F13. For some reason, I have to reinstall F13. After I login, I can not access /home. I followed some instructions like
modprobe dm-crypt
modprobe dm-mod
cryptsetup luksOpen /dev/vg_vit/lv_home vg_vit-lv_home

I have two basically identical harddrives that are encrypted with LUKS containing a complete debian installation:
Code: Select allroot@x200s:/home/b# lsblk --fs
NAME FSTYPE LABEL UUID MOUNTPOINT
sda
├─sda1 ext2 0b851969-281e-4db2-8a5b-3798e801711b /boot
├─sda2
└─sda5 crypto_LUKS cfcf63ef-448a-4f72-9f58-8f7731cf3dfc
└─sda5_crypt LVM2_member 21CS3f-SQeQ-XcMr-kyDs-OPtR-egmT-HkvJAu
[Code] ....
sda is what I currently run to write this text, sdb is my former harddrive, connected via USB.
I want to access the root partition on sdb.
The problem is:
Code: Select allcryptsetup luksOpen /dev/sdb5 oldhd
Enter passphrase for /dev/sdb5:
root@x200s:/home/b# ls /dev/mapper/
control oldhd sda5_crypt x200s--vg-root x200s--vg-swap_1
root@x200s:/home/b# mount /dev/mapper/oldhd /mnt/
[b]mount: unknown filesystem type 'LVM2_member'[/b]
[Code] ..
Before all this, both sda and sdb where in the same volume group. I renamed the volume group of sdb to "oldDisk"
using
Code: Select allvgrename <UUID> oldDisk
How I can access the data on the root filesystem of my sdb..

I currently have a simple bash script set up via cron to backup my data (rsync) to an internal hard drive at regular intervals. I leave this "backup" hard drive unmounted, and it is mounted and unmounted as needed with the bash script. If I were to encrypt this "backup" drive (via Luks, or some other means), is there a way to get my backup script to work without me having to be there to enter a password?

I'm trying to configure pam_mount to automatically mount an encrypted partition (luks) and formatted to NTFS. I typed the command in the configuration file:
Quote:
<volume user="user" fstype="crypt" path="/dev/sda6" mountpoint="~/dane2" options="defaults,umask=000" />
But the partition is mounted read-only. There is some way to mount the partition rw mode?

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 created a encrypted volume on top of software raid1. These are my steps:
1. Create logical partition on sda
2. Create logical partition on sdb (same size)
3. Change type to partition to 'fd' for both partitions
4. Check that the both partitions are same size and type
fdisk -l /dev/sda && fdisk -l /dev/sdb
5. partprobe
6. Make sure there are no remains from previous RAID installations on /dev/sdb by running:
mdadm --zero-superblock /dev/sda6
mdadm --zero-superblock /dev/sdb6
7. mdadm --create /dev/md4 --level=1 --raid-disks=2 /dev/sda6 /dev/sdb6
8. watch cat /proc/mdstat
9. update mdadm.conf
mdadm --examine --scan | grep mdx >> /etc/mdadm.conf
10. Load twofish module
[root@localhost ~]# modprobe twofish
11. # cryptsetup -y -c twofish-cbc-essiv:sha256 create ftdata /dev/md4
Enter passphrase:
Verify passphrase:
12. mkfs.ext3 -b 4096 -R stride=8 /dev/mapper/ftdata
13. mkdir /ftdata
14. Mount the encrypted volume: mount -O noatime /dev/mapper/ftdata /ftdata
It mounts successfully this first time. When I cd /ftdata, I can see the lost+found dir
Now, I unmount the volume
cd ~
Code:
umount /ftdata
cryptsetup remove ftdata
And now, if I try to setup my encrypted volume like this:
Code:
[root@localhost ~]# cryptsetup create ftdata /dev/md4
Enter passphrase:
mount -O noatime /dev/mapper/ftdata /ftdata
I get this error:
mount: you must specify the filesystem type

So why is it that I can't mount my encrypted volume after the first time? I am giving the correct password when it asks to.

I recently installed Ubunutu 10.04 Netbook Remix onto a Dell Vostro A90. During install I selected "Require my password to log in and to decrypt my home folder", and this is working great.
What I would like to figure out, is how to have a second encrypted volume that lives on my SD Card that is also decrypted automatically upon login.
I've tried a variety of things, but they all require me to re-enter my password at some point during the boot/login, once for user login and the other time to decrypt/mount the volume. I am trying to avoid this, and hopefully will only have to enter my password once. Maybe I can piggyback on the default Ubunutu home directory decryption and make it all appear seamless?

I am trying to have an encrypted drive auto-mounted once i log into Lucid.
I created the encrypted drive with the disk utility in administration menu
I also have the password remembered "forever" so when i am logged in i just click the icon for the drive on left panel and it mounts.
I am able to find the uuid and know what device is called sdd but i don`t know how to put it into fstab if that is possible?

I read an article earlier that suggested the swap partition is encrypted by default if you select an encrypted /home folder during installation, is that true (for Lucid)? I am suspecting it isn't because my hibernation works, which I believe shouldn't be the case?

had a lvm (non luks i suspect) home partition on my 11.04 install. I've since install opensue on the same laptop hoping that if i don't leave that partition alone during opensuse installation i would be able to mount and enter my key to access the data within...stupid me.... i formated my /boot and / partition, not my /home partition of 450gb. I'm now back on ubuntu 11.04 trying to get access to my data. i'v found the command "encryptfs-recover-private" but i only works on mounted partitons, i can't mount my encrypted partition because the system does not recongnize it. I've have to format it to mount it.
fdisk

I have two questions regarding auto mount function of Truecrypt. First question:
I want to automatically mount my flash drive encrypted by Truecrypt using a keyfile whenever I plug the drive. How can I do this? I use Ubuntu 10.10.
Second question:
As I do not know the answer of my first question, I currently use following command in a startup script to mount my encrypted flash drive automatically at every system start-up.
Quote:
/usr/bin/truecrypt -k ~/keyfile --auto-mount=favorites
My problem with this method is, Truecrypt always search for the drive in the same path saved in favorite drives list, e.g. /dev/sdb1. However sometimes there are more than one flash drive plugged to my computer and my encrypted drive's path changes. In such cases Truecrypt cannot mount my encrypted drive because it cannot find the drive in its path.
As a workaround I tried "auto-mount=devices" parameter. It is slow because it checks every mounted drive, and some of them external hard disk big in size. Moreover it does not recognize any mount point parameter. I'd like to mount the drive to the same mount point every time.
Quote:
/usr/bin/truecrypt -t --auto-mount=devices -p "" -k ~/keyfile /media/MyMountPoint
The command above mounts the drive however it is slow and to the destination of "/media/treucrypt1".

After buying an IBM/Lenovo USB fingerprint reader model FP06 and installing Fingerprint GUI, have problems to mount my home folder encrypted with eCyptfs. I was using it since the first time i install Ubuntu 10.10 64 bits. After login from GDM, there are some ways to make it work:
1) open a terminal window and type ecryptfs-mount-private. This decrypt the home folder, but need to logout and login again to my personal preferences can be reached (bookmarks in nautilus, in firefox, etc). Each time the PC is rebooted, the same process is needed to made again.
2) before login in GDM, change to a tty1 terminal (ctrl-alt-F1) and login from here. The personal folder decrypt then without problems. Then change to GDM (ctrl-alt-F, login an everything works fine. What could be the fault from GDM to not mount the encrypted folder?

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.

I just replaced my Fedora 14 installation in which I have an encrypted LVM which contains /home and /tmp (no, I didn't back up ), when I boot I enter my password, and get dropped to the maintainance login a few minutes later. I'm wondering how I can mount my /home from the Live system so I can just back up over the network.
I haven't worked with LVM very often so I'm out of my depths on this.
This is my partition layout as reported by the installer: screenshot
Edit: upon boot the system tells me that /dev/mapper/logvol01 and /dev/mapper/logvol00 don't exist
Edit2: Nevermind, Disk Utility is smarter than I am.

what now trying to mount partition get this error this is the partition ubuntu 9.10 is installed on and upon reboot error no device with a long string. mount: can't find /dev/sda6/mnt in /etc/fstab or /etc/mtab
so now that I believe I've successfully mounted the partition how do I direct the bootloader to this partition /dev/sda6 on /media/11076e45-e27d-470b-bb6d-6894f7809a0c type ext4 (rw,nosuid,nodev,uhelper=devkit)

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]

I had some major problems after the recent Ubuntu upgrade and had to boot from a live cd. I have a separate /home partition, but it was encrypted using the default install encryption in the 9.10 install cd. How can I get to my files so I can back them up?
I have tried this but it did not work: http://ubuntuforums.org/showthread.php?t=1337693

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?

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?
