Debian :: Tcplay Make Encrypted Volume
Apr 2, 2016
tcplay [URL] ....
Want to make a 1gb volume on dev/sdb usb memory stick.
Wrote
Code: Select allsudo tcplay --create --device=/dev/sdb --pbkdf-prf=SHA512 --cipher=TWOFISH-256-XTS,AES-256-XTS
Command has to be sudo?
Got
Code: Select allPassphrase:
Repeat passphrase:
Summary of actions:
- Completely erase *EVERYTHING* on /dev/sdb
- Create volume on /dev/sdb
Are you sure you want to proceed? (y/n)
I do not want the usb stick to be erased. What do I do, to not erase the usb stick? If you create a volume on the system hdd, it should not erase the system.

I just installed Debian Testing on an encrypted partition (using the encryption feature in the installer). Problem is when I boot I enter the passphrase and then Debian starts to load a bit and then it stops and won't move again. During a normal boot the boot stops after : EDAC sbridge : Couldn't find mci handler Then do a recovery mode boot from grub loader so more information is displayed during the boot time and it stops after : [12.513770] fb: switching to nouveaufb from simple it stops there I can't type anything, I can reboot the computer with ctrl+alt+del tho
I was booting just fine in a previous installation on a MBR-partitioned disk (now it's GPT-partitioned). I have to add that during installation I added a second encrypted volume on a HDD (while / is on a SSD) that mounts to /data. When few days ago I installed it on the MBR-partitioned disk it asked me for the /data passphrase pretty fast, now it just seems to boot and asks me only one passphrase until it freezes.

I have installed debian 6 on two of my laptops. During installation I chose to encrypt my partitions (swap, root and home). Now I find it annoying that during boot up I'm asked for password, for each of these partions seperately. I have given same password for all three of them. How can I make the system ask for the password only once. I know it can be done because on fedora it was like that before.

I have installed fedora 11 in my system. While installing it asked me encrypted password which i passed. But I forgot that. Now the problem is whenever i boot my system before going to root itself it is asking for volume encrypted password, which as i told you i have forgot. Now i am not able to access my hard disk since it is completely locked. Is there any way to decrypt the password or unlock it. Or if that is not possible can data be recovered,which is my primary requirement..

I recently got a eSata docking station for hard drives and after deciding to make those volumes encrypted LVM's, I created my first logical volume. After setting it up in yast2 and rebooting I received a prompt for the lvm password, gave it and received:
Mar 17 13:38:21 blkdragon kernel: [ 1105.172687] padlock: VIA PadLock not detected.
Mar 17 13:38:21 blkdragon kernel: [ 1105.313056] alg: No test for stdrng (krng)
Mar 17 13:38:21 blkdragon kernel: [ 1105.323189] alg: No test for stdrng (ansi_cprng)
Mar 17 13:38:22 blkdragon kernel: [ 1105.416892] padlock: VIA PadLock Hash Engine not detected.
Mar 17 13:38:22 blkdragon modprobe: FATAL: Error inserting padlock_sha (/lib/modules/2.6.31.14-0.6-desktop/kernel/drivers/crypto/padlock-sha.ko): No such device
Boot resumed and I looked for the reason for this, the padlock-sha.ko module does exist in the appropiate place and the volume was mounted in spite of the error message. Lvmdump seems to indicate that the volume is, in fact, encrypted. My thoughts at the moment are that the volume was encrypted by aes, so the padlock-sha.ko was not necessary to mount the volume. Backtracking the message log the same error happened during the creation of the volume before rebooting. The kernel version gives it away but it's a 11.2 machine.

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?

Alternate CD on USB - Natty not mounting Encrypted Volume I get initramfs prompt. I have a Dell Inspiron Duo. I've tried to install Natty i386 and AMD64. I set my / (root) and swap under LVM under an encrypted volume. Used manual partitioning. But after reboot, I successfully enter the passphrase, swap and root are not mounted.
Now, I've had this working with 10.10. System seemed a little quirky after the upgrading it to Natty. So, I wanted a fresh install. Used Unetbootin to run ISO from USB and also from one of my other partitions. I've tried installing at least 10 times, some repeat, some variations.

I've installed Ubuntu 11.04 on a Fujitsu Esprimo E900. During installation, I've used the guided encryption setting because neither GRUB nor LILO would ever install on the LVM configurations I created myself. So after installing Ubuntu 11.04, when I boot regularly, the computer freezes completely. When I try to launch the recovery mode kernel, I get this far and then the computer locks up, too. Ubuntu lockup during boot by germanium, on Flickr
You can see the label is sdb5_crypt which is a bit odd since the partition is on /dev/sda. However, I already tried changing grub.cfg to /dev/sda instead of /dev/sdb but that didn't do anything. This is all a bit odd to be. The funny thing is I've been trying to set this computer up for a month and I'm a professional programmer (Java, JavaScript, Groovy) with 20 years of programming experience and I never thought Ubuntu would be this hard to install on a more-or-less stock Intel box.

I have a 160GB harddrive with 2 partitions:
1. /dev/sda1 ext2 100MB (this is my /boot partition)
2. /dev/sda2 LVM2 Remaining space (this is my physical volume and is LUKS-encrypted)
There is 1 volume group, slackvg, and 3 logical volumes:
1. swap 2GB
2. root jfs 10GB
3. home jfs 50GB
I would like to shrink /dev/sda2 to make room for another regular partition, is this possible?

I need a FREE solution that can image an entire Luks system encrypted volume and the rest of the used HDD, the MBR and /boot partition. Note: MBR and /boot are not encrypted. Note 2: I want to be able to restore entire drive from image with only a couple of steps. Note 3: Destination HDD space is a factor. Image file must be compressed and the image file must be around 40 to 50 GB or less. The smaller the image the better.
I have used clonezilla live cd before but not for encrypted volumes. I know you can install it in Linux. But, I don't know how to configure it after installation. I would be very happy if someone could tell me how to configure clonezilla in Fedora. How to guides are also welcome. I have one more question. If I image the encrypted volumes and all the stuff I mentioned above while logged in to Fedora, and I restore the drive from the image, will the recovered drive still be encrypted?

I'm running squeeze (last updated today), and everything has been working great. There is only thing that would simplify my life minutely..Anybody know how can I have the volume buttons on my laptop change the "pcm" channel volume rather than "master"? If they could control pcm, then I could adjust the volume coming out of my headphones or my computer speaker (both controlled by pcm, but not master...seems strange to me) with just one click.I tried to find this info online, but all results seem to refer to an older version. The simple "click here, set this" solution no longer is possible.

Debian Squeeze 6.0.0 on a Thinkpad T43, sound volume is not synchronized between the laptop volume buttons and GNOME's Volume Applet. So if I turn the volume all the way down with the physical buttons, the volume applet may still indicate 75%.I did not have this problem in Debian Lenny. Pressing the volume buttons used to show a volume bar on the screen, as did pressing the mute button.

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 am running Pclinuxos with KDE 4.3.4. I have installed Truecrypt but am having problems using this program when the user is not root. If I try to mount or make an encrypted container a message pops up saying: Administrator privileges required: enter user password or administrator password
When I enter the root password a box then says: Failed to obtain administrator privileges: username is not in the sudoers file. This incident will be reported
I can't understand why this has happened as I gave the root password. Once I provide the root password, surely I become all powerful and the system should let me do anything? Also to mount a encrypted file in Truecrypt I have to assign full write permissions for users to the /media directory. Is this safe to do?
The only way I have found to use Truecrypt with a non root user account is to go to super user mode terminal, sign in with root password, CD to the truecrypt directory and launch Truecrypt from the terminal. I find this very laborious to do every time.

I just built my first computer from the ground up and installed linux x86_64, FC10, and among other problems, i cannot get the volume of my speakers to play much above a low volume. i have the pulseaudio volume control set to 100% for the output and input levels. i adjust all my video and audio players volumes to the max also, but the volume from the speakers is still very low. the speakers worked fine with my old hp computer. is there anything i can do, adjust to fix this?

Several days ago, I replace my PC's motherboard and now sound is too low - I can't hear practically anything, I used alsamixer to configure output volume level to normal, but this won't survive reboot.
I tried to use 'alsactl' and saveed rules, and edited rc.local to restore - but it didn't help. Can anyone tell me how to fix it?

I'm using ubuntu lucid lynx (64bit).
In alsamixer, the speakers volume is set to zero and I can't hear anything (headphones work properly, though). I turn it up and the speakers work, but each time I reboot it goes back to zero. I've gone through the alsa wiki without finding anything. Can someone tell me how to change the default values in alsamixer so speakers work on start?

installed F12 and noticed that the volume control applet is now all Pulseaudio rubbish, not Alsa like gmixer used to be. So now I don't seem to be able to mute my speakers when I'm using my headset, which in F10 I could do by just muting LFE/Center.Note I don't want the speakers to be disabled when I have the headphones plugged in (like Jack does) I just want to be able to control volume of the mixer channels individually - as sometimes I'll be playing music through the speakers and will receive a Skype call and want to mute the music, but also don't want the Skype sound coming out of the speakers - just the headphones.
I've tried setting up 4.1+input, 5.1+input, 4.0+input etc; but for some reason, even though the PulseAudio mixer thing has 5 individual sliders, they do nothing as they "jump" back to 100% when you slide them - even with the channels unlocked. gmixer and alsamixer do the job, but pulseaudio is the applet and only seems to control the master volume, not the individual channels. Any ideas - or perhaps a way to make gnome-volume-control revert back to actually being gmixer?

I have an imac and i recently decided to dual boot Ubuntu as well.
The sound is fine on the mac partition but the internal speakers dont work on the Ubuntu side.
headphones do work but the volume is oddly low
Nothing is muted on alsamixer, and I think i have the right driver for my sound card

I installed Ubuntu 10.10 64 on my laptop with the entire 500gb setup as encrypted LVM. This has worked well for several months with no problems. During this time i have been backing up the data to an external usb drive (1tb) on a regular basis. The usb drive was not encrypted. So, I thought it would be a good idea to encrypt the backup drive too. I wiped out the backup drive and set it up as one large encrypted lvm and mbr. This seemed to work fine but immediately afterwards I decided to erase that and set it up as encrypted lvm guid instead of mbr. I couldn't delete it while logged into my desktop so i decided to do it from a bootable gparted usb stick. In gparted i erased the 1TB backup drive once again and planned on setting it up the way I wanted once I was logged back into my ubuntu desktop. Now I cant boot into my desktop with the following errors:
cryptsetup: evms_activate is not available b0d) does not begin with /dev/mapper/
Then after waiting for a few minutes I get an error followed by (initramfs)
When booting from a live version of ubuntu the 250MB boot patition is recognized and 500 partion is there but it is labeled as empty/unused.
Also, I did choose to use the exact same passphrase as what is used on the main bootable drive when I set up the encrypted partition on the external 1TB drive.

I installed 4 encrypted partitions (/, /var, /tmp, and swap) that are mounted at boot using the Alternate Installation Disc, and they all have the same password, but I have to type that password in 4 times when booting up. How do I make it so I only need to type in my password once?

I've just started using ubuntu one. However, some of the files I store on there are sensitive so I encrypt them using seahorse. Right click, encrypt etc etc. My question is, is there a way to automatically get the encrypt process to delete the un-encrypted file when it makes the new encrypted copy?

I have a problem with my debian install. I 've got a laptop with 3 OS:
First I installed windows.
Then I installed ubuntu 15.04 in an encrypted partition, and another partition with /boot (/dev/sda6) created when I installed Ubuntu.
And, finally I installed Debian 8 in an encrypted LVM (/dev/sda8) with 3 partitions (/, /home and swap), and a /boot (/dev/sda7) partition created when I installed Debian.
Needless to say that both /boot partitions are not encrypted
Previously I had a similar configuration with ubuntu 14.04 and Debian wheezy.
The problem is that I can't start the system by using the Debian grub (/dev/sda7). So Ihave to boot the system using Ubuntu's grub (/dev/sa6). The second part of the problem is that when I boot Debian using /dev/sda6 (ubuntu's grub) , plymouth does not work.
I tried purging grub and reinstalling it again with the ubuntu partition mounted, and it did not work.
I did not have this problem with my previous configuration (with wheezy and xubuntu 14.04) ...

The system disk on my lenny 64b system is using LVM, encryptions and XFS (/boot is ext2). I'm looking forward to turning it into old-style, ext4 unencrypted partitions (and thinking about btrfs in the future. Despite having used Debian for many years now, I haven't really ever tried a true migration and all of the guides out there are concerned with turning an unecrypted to encrypted. My basic idea was to use the installer and set up a minimal new system on a fresh disk, then migrate all of my stuff from the old system.
I have some doubts though
1- is this the easiest way to get the task done?
2- what do I have to copy from the current system /etc? and most importantly, what I should *not* copy?
3- how do I replicate the current package configuration on the new system without falling into a dependency hell?

I have buyed a dvd, but I can not play it. I've installed libdvdcss2 and libdvdread4 already. However, when I start Totem, it doesn't work. It says: "Could not read DVD. This may be because the DVD is encrypted and a DVD decryption library is not installed". I use debian stable (wheezy).

I have a system which i installed on usb flash (doesn't matter why). The system has 3 partitions: "boot", "/" and "swap". "Swap" and "/" are encrypted by LUKS. "Swap" is encrypted by random key, "/" - by passphrase.
I created this system only to make a liveDVD from it (not liveUSB).
To achieve this goal i installed program called "Systemback" (fork of Remastersys).
Links:
[URL] ....
[URL] ....
So i pushed the button 'Create live system' (or Live system create, don't remember exactly) and configured it to automatically convert .*sblive to .*iso
Program made it's work and i burned image in DVD.
But when i launch it i have this:
The last picture - is when i trying to startliveDVD with installed LVM2. No difference except one message.
I went to freenode and ask some questions. Somebody told me that maybe the problem is in LVM. But LVM was already installed, so i installed LVM2. No result.
How can i make the system that is encrypted by LUKS work from DVD? And is it really possible? Maybe systemback doesn't support feature to make live-image of encrypted system?
The system is Debian 8.1.0
I did the same with nonencrypted system - result is succesfull, liveDVD works.
