Debian :: Auto-mounted Truecrypt Partition (keyfile Based) - Can't Add A Keyfile To The Volume Using The GUI
Nov 18, 2010
I have a Truecrypt-encrypted Windows [system] partition, that I want to be opened and mounted automatically (using a keyfile) when I log into Debian, since it is also encrypted and I don't want to type two passphrases. It think this could be done with LUKS. With TC I probably have to go with the CLI, but haven't figured it out yet. And I can't add a keyfile to the volume using the GUI. In order to mount the volume I have to tick the Mount partition using system encryption (preboot authentication) checkbox, or otherwise I get Incorrect password or no TrueCrypt volume found. And same when I try to add a keyfile.

I have install a debian jessie in my laptop, i create a lvm volume with /, /home, etc and a /boot partition outside. the i move this partition to the lvm volume and boot from it, everything it´s okay and it works.
The problem is that wen boot it ask me the passphrase to load grub, and then, when grub loads the kernel, it ask me again the passphrase.
I read that i can pass a key file to the initramfs to solve this, but where i see it, he uses mkinitcpio, and i can´´t find this package in the debian repos, it an arch package, also i tried this option [URL] ...
But it asking me the passphrase 3 times, and the third fails, the sistem starts, but i read the fail in the log.

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".

I keep my /boot partition on a usb stick, where i keep the keyfile as well. I already generated the keyfile and added it to the LUKS LVM partition.Right now, on bootup I get a nice GUI to enter my 40 character password which is nice but a little tedious What do i need to modify for the system to automatically unlock the partition with the keyfile that is stored on the /boot partition

Recently set up root encryption with a couple of LVM volumes inside one LUKS volume, and I am just a little confused as to how I would go about getting it to automatically unlock using a keyfile stored on a USB flash drive, I presume I would have to put the drive in the fstab inside my initramfs (if there is one), and add a hook for USB device support.
But I digress, essentially, I want to know what I have to do to enable my LUKS volume (containing all of my partitions sans /boot) to unlock using a keyfile stored on a USB flash drive, rather than a manually entered passphrase.

I can't seem to get an encrypted partition to recognize a keyfile. It is a backup partition that I would like to keep unmounted until a cron-script runs once a week to backup my sensitive data. In order for the script to run without my assistance, I thought I'd use a keyfile to authorize the mount.
So far I've created a keyfile and have added it to the partition using "luksKeyAdd". It didn't really say it was successful, but when I do a luksdump, it shows that another key slot has been enabled, so I believe it worked. After that I created a /etc/crypttab file with the following:
Code:
backup_sdd1 /dev/sdd1 /root/backup luks
/dev/sdd1 being the backup partition, and /root/backup being the keyfile
After rebooting, I am still prompted for a password when trying to mount the encrypted partition (sdd1), and there is no device "/dev/mapper/backup_sdd1" created like I believe there should be. I haven't added any entries to fstab, as I don't want this partition to mount at boot.

I just did a yum upgrade from F13 to F14 to F15. According to /var/log/messages NetworkManager crashes trying to parse a VPN keyfile:
Code:
NetworkManager[2519]: ifcfg-rh: parsing /etc/sysconfig/network-scripts/ifcfg-eth0 ...
NetworkManager[2519]: ifcfg-rh: read connection 'System eth0'
NetworkManager[2519]: keyfile: parsing VPN Connection UDP ...
NetworkManager[2519]: <warn> caught signal 11. Generating backtrace ...
I'd like to remove this VPN config in hopes that NM can init and run, but I cannot figure out where this configuration is stored.

I have a 2nd hard drive that I have encrypted using true crypt. Is it possible to set this up with key files (or some other way) to auto mount when linux boots. I need it in true crypt because there are some work programs I dual boot to use in windows, and need to have access to the drive in XP from time to time, and true crypt can mount there as well. But 90+% of my time is in linux and I would like to have it auto mount through fstab (or whatever way it needs to be). My entire linux setup has been set up with encryption through dm crypt and LUKS (except for /boot). So I would think having a key file stored on the computer and an auto mount fstab would be just as secure as however secure my LUKS setup is. So any way to auto mount a true crypt 2nd drive volume?

I'm using LVM-based partitioning. I can not mount one partition. Here is some information I can provide.
Untitled-1.png

This incident happened after I try to encrypt this partition and then an error message appears. If not mistaken, it contains an error number (I forget) and a warning which reads that can not remove the LABEL on the devices.

I have recently installed Debian on my NAS server. I have also configured Samba for sharing the home directory of a nas user i.e. /home/nas To this directory I have read/write from a windows machine using the nas user credentials.
When I mount my RAID partition /dev/md0p1 to the /home/nas directory, I then realize that all content in this directory (files and subfolders) is only owned by the root user. When trying to access from the windows machine the /home/nas directory, I do not have any write access, only read. I have tried both the nas and the root user credentials.
I have also attempted the change the ownership of the mounted RAID partition to the nas user with the -R recursive option, but I get for the internal files/subfolders an error "operation not supported".
How can I overcome this problem?
- Is there something not done properly in the /dev/md0 array definition (i.e. ARRAY /dev/md0 level=raid1 num-devices=2 UUID=bddf8b69:c97967b5:cb104784:7fef7cc3 )?
- Is there something not done properly in the /dev/md0p1 mounting (i.e. mount /dev/md0p1 /home/nas)?
- Should I do any extra configuration before the mounting etc?

Can't seem to figure out how grml is stopping the auto-dhcp during boot by default in grml network is disabled. I tried init.d, inittab, or whatever I cannot seem to find anything? I need eth0 to come up automatically at boot grml, for some reason won't remember my net setup and must re-setup at every boot? How can I make it do that?

I have successfully mounted my Win7 volume and my external hard drives NTFS volume as well. However, after modifying the fstab I seem to only be getting the win7 volume to auto-mount. Below is the contents of my fstab. /dev/sdf3 is not mounting. Again, it works no problem if I manually mount it.
# /etc/fstab: static file system information.

I successfully created a TrueCrypt volume and mounted it and put some files there.
Then I tried to unmount and just could not.
I can still see the files when I go to /media/truecrypt1.

I have a dd image of a full drive (as a file) that was using Truecrypt system encryption under windows. I want to mount the main partition from that image using Linux's Truecrypt. I am familiar with dd loopback devices and have the partition offset, but I don't know how I can mount it like this because I need to use the truecrypt command.
Is there perhaps some way to create a fake device file for the disk image that I can mount from within Truecrypt?

I installed TrueCrype 6.3a on my 8.1 Ubuntu. Everything went fine until I got to the part where I need to protect my hidden volume from damaged caused by writing to the outer volume (these instructions: [url] ). I can't find the checkbox to "Protect hidden volume from damaged caused by writing to outer volume". The closest thing I can find is an option to "Protect hidden volume when mounting outer volume". Intuitively these don't sound the same to me. There are 2 difference between my setup and the instructions; 1) the instructions appear to be written for Windows and not Linux. 2) I am using a file volume and not a partition volume.
Does anyone know where the option is to protect the hidden volume when writing to the outer volume?

I installed TrueCrypt in Microsoft Windows XP SP3 (no Linux installations present) and I stopped the TrueCrypt service in the Windows enviroment, and then, I restarted, and all the sudden it seemed the PC can not see the Hard Disk at all at startup, nada... I believe I dismounted it by stopping the TrueCrypt service... So the PC no longer understands there is a TrueCrypt volume in place, and I inserted the TrueCrypt recovery disk, and it can not do any thing, I restored the bootloaders, the true crypt loader, and once I finished this, I press ESC, and it says there are no bootable devices, so nothing. I even decrypted the disk, and it seemed that nothing happened with the restore disk...
Is there any way I can make this partition bootable again? because I have every thing in that partition, every single bit of life... I have used TestDisk under Linux right now, but I am unsure of this, and I also further complicated the boot proccess, and now the PC states at startup about missing partition tables. When I start truecrypt from this Kubuntu live CD, I am unable to see the encrypted hard disk even with root, there is no way to see this hard disk, only can be seen in the TestDisk app. I really I am desperate, at least, if I can not make Windows Boot again, maybe just suck all the files out of the hard disk and put them some where for now, I really need to get back to work, and I cant seem to find a solution...
I know here at Ubuntu forums, some one may have the solution. And I do know for sure all the files on this volume are there because of the TestDisk app, so they are there, they are just not reachable.... (I have posted this problem on a Linux forums instead of a Windows forum because the only way to try to recover the volume is with Linux Kubuntu Live CD

If one uses a free ftp account to store private data such as bookmarks, they might prevent any eavesdropping by using ssh for the transfer (ftps), or alternatively sftp.
However, they would still have to trust the ftp hosting provider, because the data is stored unencrypted in the server.
Someone suggested putting all bookmarks in a small truecrypt volume instead and synchronizing this with the ftp server.
Performance issues aside, given that the plaintext only changes a little in each resync (only a bookmark is added usually), is the use of the truecrypt volume introducing a means for an eavesdropper to break the code?

This one being Ubuntu 9.10 (yes, I know I really should upgrade). I keep a number of confidential files in a TrueCrypt container which is a standalone file in my Documents folder. I'd like to delete some of these, but I want to do it as securely as I can, but I believe if I simply hit 'Delete' with the file selected it'll move the file to the Deleted Items folder. This, I assume, means that the file is taken out of the encrypted volume and stored unencrypted in the Deleted folder.
I've been reading a little about the Shred command, and there seems to be some question about whether it works effectively with a journalled file system; and since I have no idea whether I'm using a journalled file system, or how to find out, I'm treating Shred and other over-writing secure deletion tools as ineffective for now.
With this in mind, can anyone advise me how I can protect the file stored in the TrueCrypt volume, and delete it in place, without taking it out of the encrypted area? And, further to that, can anyone tell me whether in fact the file is actually secured while it's in the encrypted volume? For all I know, just opening the volume may result in copies being made somewhere (apart from RAM).

I have a Windows partition encrypted with TrueCrypt. If I start TrueCrypt (or RealCrypt) I can mount the partition through the GUI. before I encrypted the partition I used to auto-mount it at boot using fstab and it would appear in my places bar in the file managers. Is it possible to auto-mount truecrypt partitions from fstab?

I would like to resize the /home partition but it is mounted and when umount is run, it errors with 'busy'.
System Configuration:
I installed jessie on a laptop with one SSD. I used guided partitioning and selected the whole drive with multiple partitions. The /home now takes up 420 GB. I would like to reduce that to 20 GB to make room for another partition.
What are the methods reduce this partition?

I have created a TrueCrypt volume, mounted it in Windows, and created an image file for my OS partition using Macrium Reflect (free version). I made a Rescue CD for Macrium, and the setup works great on unencrypted files, but I have no way to mount the TrueCrypt volume, while booted to the Macruim rescue CD. I have Puppy Linux 4.3.1 on a CD, and can boot to it. I'm a beginner's beginner, however, and I haven't figured out how to install TrueCrypt with Puppy Linux running. Getting the Macrium recovery program to run with the TrueCrypt volume mounted looks even more complicated, and I don't know if it's even possible. I want to be able to recover my laptop from a drive failure, as well as protect my OS from bad programs or malware. Macrium reflect does this job well, because it:
1. is free
2. only writes the used space of the system partition to the image file, and also compresses the data, resulting in a relatively small file. (~ 50 percent of the used space on the OS partition)
3. retains drive alignment for a pre-aligned partition.
However, I wish to keep my backup partitions encrypted to protect my privacy. TrueCrypt does an excellent job of this because it:
1. is free
2. encrypts the OS and all data on the computer.
3. protects all backup data.
I like the fact that Puppy Linux can be loaded into memory, so I only need to boot from removable media to work on my OS partition. I understand there is a portable Ubuntu OS, and perhaps this would be a better platform for my goal? Is there a way to combine Linux on removable media, with Macrium Reflect, and recover an image from a TrueCrypt volume?

How do I configure my Debian installation to mount external USB drives to mount points based on the volume names of the drives? For instance, if I have a thumb drive with the volume name of "SWORDFISH," how do I have Linux mount it at /media/SWORDFISH? I'm aware that this can be setup in FSTAB, but that requires that I know the UUID of the device beforehand and that I take the time to set each external device up in FSTAB first. That does nothing for me when I have a thumb drive that has never been plugged into my computer before.
This seems to be setup by default in Ubuntu/Kubuntu, but is not working for me with a fresh installation of Debian Squeeze and KDE4. I've spent the past 2 hours Googling for a solution and have turned up nothing. UPDATE: My results are inconsistent. Sometimes Debian mounts devices to mount points based on the volume names, and other times it gives them generic mount points (e.g. /media/usb1).

I have an Ubuntu 10.04 machine at home and apache setup on it (files are located in a Truecrypt volume). The reason for the web server being that I wanted to access my files wherever I'm at (i.e. hotel, work, hotspots, etc...). So far, it's worked out great for me seeing as a I can http download my files (or stream media files). However, I am often on a public hotspot and I know it's a matter of time before someone finds the webserver on my computer. I have the machine firewalled and password protected (via .htaccess), but either way I don't want people looking in on my computer.
The problem: I have used Truecrypt for a long time and completely trust using the program to encrypt/unencrypt a volume container to store my files. Usually, I would remote desktop into my computer and mount/unmount the volume when I needed it. However, after time it get's really annoying to do this. So I eventually figured out how to setup a bash script to automatically do this for me (which I put on the usb part of my phone). What I wanted to do was to be able send the bash script to my Ubuntu machine (via ftp from my phone) and have Ubuntu automatically run the script. Is this possible? What programs do I need on Ubuntu?
I was thinking about using something like cron, but that is for scheduled times. I don't really have a set time in which I need my files, it's pretty sporadic depending on how much I travel. Thus the need for being able to remotely mount the volume when I need it.
Summary: I need a way for Ubuntu to read a folder every minute or so to check for bash scripts to run. I want to be able to send the bash script via ftp from my phone, have Ubuntu run the script, then delete itself (so as to not store the password). I already know the script in which to mount the Truecrypt volume and how to send the file via ftp from my phone. It's really a matter of what program to use in Ubuntu to find and run the script.

I have v 10.10 running the following (and I still have no idea how I got this all working). Myth, Squeeze server, X10 control system for the house, Virtualbox (where I run some windows stuff) and a general file and print service. It has 5 disk drives attached
1 - system disk
5- external usb to back up data to
2,3,4 - 2 tb drives in a raid config
I just restarted the server and the raid volume has not mounted. I looked in the webmin interface and the device is there but it doesn't seem to have the partitions attached. Again in webmin, the partitions seem to be on each of the drives. I used crash-plan to back up the data and music, but not the video, so I would prefer not to have to rebuild the lot if I don't have to. I really don't want to re build the lot out of my lack of experience with Linux. Is there an easy (ish) way of putting the raid back together to see if it's just dropped its config and the data is in tact (or can be rebuild from two of the three drives).
