Ubuntu Security :: Access Encrypted Hard Drive Via Live Usb?
May 17, 2011
I want to access my hard drive to copy over my old documents. So I boot into a LiveUSB, mount my ubuntu partition, and then cd to my home directory, but I can't open it. I get "permission denied." I encrypted my whole home directory and know the password, but how do I "decrypt" it or login as the partition's root so I can access the documents that way. I'm booted into the USB, but can't access the home directory. I get "You do not have the permissions necessary to view the contents of 'jake'".

What i really need to know is if there is a way to access a Ubuntu file system on a hard drive from a live CD. When i acess it now it just shows the Windows files on it, and i cant access the Ubuntu partition. What happened was this: I was trying to install Ubuntu on an external hard drive. I moved all the settings to the Hard drive so i didnt think it would affect my other drives. I mustve missed one of them because insteading of loading GRUB like it normally does, it came up with GRUB error 21 and did nothing. I tried to fix it, but nothing worked. I finally decided to unplug everything except the external and install it from there, so id atleast have a functioning desktop. As it turns out, my comp doesnt suport USB booting. So the only way i can use my computer is by Live CD. I was trying to fix things so i had both hard drives power supply unplugged. being slightly drowsy from staying up late that night, I plugged them in while my computer was on. the first one went in just fine, no problems. The second one though, also my master drive, i was having troubles pluging in. while i was turning it to fit in, it made a big spark and shocked my master drive. That drive had my MBR and Windows on it. Now It cant find a MBR, and i cant access the ubuntu partition on my slave drive. Is there any way to save this?? im 99.9% sure ive screwed myself over hardcore epically, but im hoping to save at least 1/2 my data.

I've installed F10-live.iso onto a usb key but am having problems with the non-privileged user I created. When I login as kurt, I do not have access to my home directory on the hard drive. I tried [root@localhost home] #chmod kurt kurt (after cd-ing to the correct spot), but still cannot access my files there. I can do so as Live System User, but not as me.

My wife's XP has crashed and I need to save files. I've discovered the command to mount the hard drive - unfortunately I need to force the mount, but I can't do it because I have to be in root. I can see the root user in the user list, but when I try to switch I can't access it. How I can do it to back up my wife's files. I have Kubuntu 8 and KDE 4.1.

What I want to do is pull data from any of the hard drives attached to my Linux box from my Windows machine. I have been moving small amounts of data from the drives to my OS drive and those parts share easily, but I want to move away from that method to move large amounts of data at the same time.I have tried using Samba as it is used for file sharing between systems and that I have to give my Windows box permission through Samba.
Trick is, I'm not sure where to start, though I have an idea and wanted to know if this is the right track before I start editing my file system.

My laptop has only Debian on it. Except for /boot, the entire hard drive is a giant encrypted LVM partition. It takes Clonezilla 13 hours to back up to a USB hard drive without verification, long enough to make sure backups aren't done much. Is there some way to make an encrypted bare-metal backup of only what is used (except swap) instead of every sector? Backing up across the LAN would be ok.

I am looking for a guide for Fedora 13 that tells me how to:
1. Create an encrypted partition on an an external USB hard drive
2. Tells me how to setup Fedora to ask me for the passphrase when I plug in the drive
3. Automounts the hard drive to a set location
The guide should deal with the situation that the computer can mount without declaring the external hard drive is not there.At present my attempt at mounting my Samsung Story USB2 hard drives does not meet criteria 2 and 3.

I am running Fedora 14 with the Gnome desktop and I have a 1 TB external hard drive that is msdos with approximately 200 gbs of data on it. I can unlock it and even read and copy files to my internal hard drive but I cannot add files to it, I use to be able to. I didn;t think i changed permissions.

My company web access is behind proxy(http://abc.proxy). Network admin can get to check who is top10 user and web they access. I owned a centos server. I have a thought that create an encrypted tunnel within proxy so the admin cant detect my http address. This is how it going to works
client with OpenVPN -> OpenVPN server(centos with company proxy)-> proxy -> internet
My connectivity in my client are using OpenVPN server as bridge. Hence, no record for client is recorded in my Network admin monitoring list. OpenVPN server's activity can be traced by network monitoring tools, just assume that our ultimate goal is to hide client activity.

I logged in to Recover Mode ("Drop to root shell prompt") this morning to do something. Naturally, I wanted access to my encrypted home folder.
The README file says to run ecryptfs-mount-private. However, that command returns an error:
"ERROR: Encrypted private directory is not setup properly."
This cannot be correct, because if I log in normally, I get my home folder without any problem.
How can I access my encrypted home folder when I boot via Recover Mode?

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".

For some reason, Ubuntu 10.4 LTS cannot boot normally, so I have reverted to a live CD, no concern, I can just reinstall, what I am concerned with is the fact that I get my music. I load up the live CD, and I am able to access my hard drive, but I as I found my music folder, I cannot copy and past and/or move ANY folders into a flash drive. It says I do not have permission.

I'm mostly a linux-idiot but I tried to get an update for a laptop that was running xubuntu. Anyway, it won't boot and instead takes me to a screen where it says "press s to skip mounting, or press m to recover manually" or something like that. I've pressed S, and then it tells me that it can't find /tmp or something, and I have to turn it off and back on to do anything. Pressing M doesn't help much either... at least not for a mostly-linux-idiot like me. I would do a clean install, but there are a few files I absolutely have to have from the hard drive. recover the files I need from my hard drive to a usb drive while using a Live CD?

I have just finished building a new computer and it booted with no problems from the hard drive to ubuntu 10.10 (it was a hard drive from a previous computer and had ubuntu installed). After less than a minute though it froze up completely. I restarted and now cannot get ubuntu to boot. I get to GRUB with no problems but when I try to boot ubuntu I get a black screen with a blinking cursor in the top left corner and it hangs indefinitely.
I tried to boot from a live cd to see if there was anything I could do but I get as far as the screen to choose "Try Ubuntu" or "Install" and both choices leave me on a black screen with the mouse icon. I can move the mouse but nothing else. I have tried the Ubuntu 10.10 32 bit, 11.04 64-bit, 11.04 32-bit and even Mythbuntu, which I had on a cd from a magazine. I get the same result with all of these.
On the other hand, OpenSUSE 11.4 boots from the Live CD fine and I installed it and it boots from the hard drive. This is good news but I would much prefer Ubuntu, as I'm more used to it. Am I doing something wrong or have I any hope?
The computer specs are:
Processor: AMD phenom II X2 555
Motherboard: Asus M4A88TD V-EVO
Memory: G-Skill Ripjaws 4GB Dual channel
Hard Drive: Seagate Barracuda 200GB

A recent update messed up my Ubuntu (actually Xubuntu) laptop, and so I want to recover a few important files off of it before reinstalling the OS.I cannot boot into Ubuntu on my hard drive, so I put in one of my Live CDs, but couldn't figure out how to get the files from my hard drive.I googled the problem, but all the solutions talked about recovering Windows files with a Live CD.I need to recover my files that were in Ubuntu

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 just setup an old computer with Suse 11.3. My goal is to store all my movies and stuff on the Suse box and access them through my home network. I have 11.3 installed, got the network setup and working, can access the internet, access files to/from my laptop to Suse box, and can even access movies/files on the Suse box from my WD Live media box. The problem is: when I add an external drive to the Suse box my WD Live does not totally 'see' it. he external USB drive is accessable on the Suse box as I've moved files to and from this external USB drive. The drive is a WD MyBook. I setup sharing in Samba and the WD Live sees the drive but cannot see the files. Is this a permission thing? Pretty sure I setup Samba correctly as I share several directories in the Suse box.

Is there a way to install grub2 from a linux live cd when linux isn't installed on any of the partitions? I'm setting up a multiboot partition for someone and I don't want to install linux anywhere on the computer since hard drive space is running short.

I decided I'm going to go back to a dual boot to see if I can get some of the slackware issues resolved on my laptop; its ubuntu only at the moment due to wireless problems. I've only got one hard drive so I can't simply unmount and repartition from gparted, I've lost all of my random linux live cds, and can't find a spare blank optical disc. Is there a way to boot from directly from the iso or from a flash drive or something?

If an old bios and mainboard is being used, such that it cannot handle the large size of HD, then is it useful to say use a live CD and from its initial menu (pressed a key), choose 'Boot From First Hard Disk'? Would this be similar in getting around a bios and disk size limitation I wonder - like - does the use of a live CD in this way avoid using the bios to point to the active partition??
The reason for asking is that a friend has a couple of quality old rack mounted server machines and wants to use Ubuntu having now fitted 80 GB empty drives. Live CD seems ok, and 11.04 install goes ok but on boot up grub comes back with an error.
I recall that early machines cannot see larger(?) HDs for booting purposes even though installs go ok in very large HDs. I wondered if a live CD to boot up temporarily - trouble shooting - would be worth trying for this reason, or am I way off?

I have a dual boot machine with WinXP/Linux Mint on it. I am looking to erase both of them and put up Ubuntu 11.04.
I have chosen to go with a live USB install for this. The live USB boots fine and everything seems usable. However, when I tried to install it would tell me that I do not have 4GB available for the install which seemed a bit weird since I have a 160GB Maxtor HDD.
After digging around a bit I realized that the system does not see my hard drive. Running fdisk -l would only show the USB drive that I am booting from and not the main HDD.
I tried to have a look in /dev to see if my HDD is there and not mounted. But aside from sda which is the USB I did not find an sdb or hd entry.
Has anyone encountered a similar problem while trying to install Ubuntu 11.04?
P.S.: The HDD works fine, I can see it in BIOS and in the other 2 OS-es that I have installed.
