Ubuntu Security :: What Are Options In "locking" Hard Drive
Feb 13, 2010
I have a 500 gb external hard drive with tons of personal files on it. Other people at home just grab my hard drive whenever they need to transfer files. I feel so disrespected. I also want to protect myself from actually losing my hard drive to a stranger who will compromise my data.
I'm thinking of encrypting, but I'm currently too busy to explore (the options seem to be hard to use) and it seems to be too much to encrypt a 500gb hard drive
What are my options in "locking" my hard drive. I don't mind if it's going to be readable only on Ubuntu. That could actually be a plus
So I have the burned ubuntu CD, and I'm attempting to install it on a system that has one HDD with XP/Vista on it, and another that is completely formatted and unpartitioned. However, when I boot to the ubuntu CD, I can use the menus from the bottom, and select the language when initially prompted, but I can't select any of the menu options except for boot from first hard drive.
At first I thought it was the daily cron jobs, but it's been at it for like 3 or 4 hours. It's driving me crazy locking up my system. I suppose I should get off the computer anyway, no real reason to be on for so long.
The only things that look weird in system monitor is kwin, virtuoso-t and X seems to be higher CPU usage than it should. And CPU usage is 20-50% when I'm not doing anything. It was indexing my files.
But how do I mount the sdc drive with those options from the command-line without restarting? I've tried to do so with 'mount' utility, but had no luck.
I'm running Opensuse 11.2 and am using a couple of USB hard drives to store large data. One of these drives is formatted with FAT32 and one with NTFS. When I plug-in a USB device KDE4 shows me a little pop-up asking what I want to do with it, I select to open it in Dolphin which of course automatically mounts it.
My question is what if I want to change some of the mount options - is this possible without reverting to manual mounting? And second question is what system does it use to automount - Fedora, Debian and Ubuntu are all deprecating HAL in favour of pure udev, is this the case in Opensuse too?

i have just recently purchased a SeaGate 1TB External Hardrive. i have very sensitive information on this storage unit that i only want certain people to have access to. is there any way of password protecting the hardrive? preferably using linux or what are my options?
So what I want to do is encrypt my entire hard drive, but heres the thing.
I dual boot Ubuntu and windows 7, but I am afraid that if I use truecrypt to do the encrypting that it will wipe GRUB and not allow me to boot into any OS, is that a possibility and is there a way around it?
I have a friend that has a computer running UBUNTU he has not used in a while and has forgotten the user name and password for it. Is there away to retrieve the data from this hard drive?
I'm installing fedora 12 on a laptop using the live cd, and I have a few questions about the encryption process.
First, I'd like to fill the drive with random data. I've read the fedora documentation and it suggests using the following command: dd if=/dev/urandom of=<device>. The installer didn't offer an opportunity to do this, so I opened a terminal and typed the command. I expected it to take hours on my 160 gig hard drive, but it only took about 3 minutes, and indicated about 600 megs of data had been written. Did I do it correctly? According to palimpsest, my boot partition is sda1 and the other partition is sda2, so that's the one ran the command with.
Second, I need some advice on what to encrypt. The installer shows me the following layout after I select encryption:
LVM Volume Groups
Hard Drives
I know I can't encrypt boot, but I can encrypt lv_root and lv_swap. But is it necessary to do that? And tell me the pros and cons of using a boot loader password?
I encrypted my hard drive on my media PC but it's really annoying having to type in a password every time I turn it on. I chose a short password so it was quick and easy to type in but is it worth encrypting data with a weak password?If the computer is suspended, someone could come along and resume the computer. They would be presented with a locked GNOME session) but the data would be unencrypted; does this go against encrypting the hard drive? Or does the locked GNOME session provide enough security to keep an intruder out?
I have recently bought a new laptop, installed my first linux OS on it (Ubuntu 9.10) and an external hard drive with 500GB on it for backup. For the first few days my external hard drive was working fine, but then eventually it wouldn't let me copy/move/delete stuff to and from it. So I kept trying to change the permissions but it wouldn't let me.
I figured this would be a very very common problem, so I looked up some forums to try out the methods but they didn't work. So I thought I would ask you guys for help because I am pleased with the support. I wouldn't think this would be a hard problem to solve.
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.
I have an external hard drive that has all of my Apple Powerbook G4 files on it. I plugged in my "Journal Extended" external hard drive into my new HP laptop with Ubuntu 10.10 on it.
All of my files are on the hard drive still, however lots of them have a little X on the folders and when I try to open them it tells me I don't have permission? How can I force the permission for everything on my external? It's my own files and I can't even access them lol.
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'".
I've got a few laptop for which I'd like to encrypt hard drive with the help of a smartcard.Does one techno (LUKS, true-crypt,) support smart card for getting the secret/passphrase ?
I have an OpenBSD and a FreeBSD system and a mac. I also have a Ubuntu server. What i would like to do is back up all these systems to an external hard-drive using rsync when the external usb disk is connected to my Ubuntu box.If i format the external usb disk with cfdisk and the create a non-bootable ext3 file system on this external disk and create and put all the necessary public keys on the Linux box then from the BSD's or the mac issue the command:
Code: #rsync --progress -avhe ssh --delete / user@ubuntuBox:/usb/disk/path/dir/ Will this back up the entire systems so that they can be restored in the event of an emergency? I should store each OS just in a separate disk file of the external usb drive each time right?? Because i would rather not have to format the external usb drive for each different OS. Would this work? and would the restoration command for these BSD's be:
Code: rsync -avze ssh UbuntuBox:/usb/disk/path / I just need to know the basics. I'm sure given that i'll be able to automate the process. I don't want to clone the disks for forensics. I just want to have a way of restoring to a clean OS. This is the most basic question:All the howto's never mention whether or not you have to have an rsync server running on the machine your backing up to. So do you just push or pull from one end of the connection only or do you have to have a client at one end and a server at the other, as is traditional?
Ok, one more question on nameserver security. So I was reading this post and it recommended not setting a defined outgoing port for your nameserver due to the Kaminsky vulnerability.What is the proper way to lock down a nameserver, but avoid the vulnerability of only allowing incoming and outgoing requests on port 53
I want to view a hard drive and see if it has all zeroes, how would I do this? I want to view a hard drive and see if it has all random data, or random data mixed with zeroes. How can I do this? I prefer to do all this in linux if possible without a gui...so looking for any cli tools to view with.
I've been running Linux for a year on our family computers (one desktop, one laptop and two netbooks). I've run into a problem with the encrypted ext4 partition (270GB) on a LaCie external hard drive which also has a NTFS partition (50GB) which is not encrypted . First two times I tried using the encrypted ext4 partition (from two different computers) it worked fine but now I can't access it at all. I can still access the NTFS partition.Encrypted external hard drive partition will unlock but won't mount (or unmount). The computer says "Opening 320GB Hard Disk" but after a minute says, "Unable to mount location. DBus error org.freedesktop.DBus.Error.NoReply"Disk utility (GUI for gparted I believe) states that the encrypted partition (/dev/sdb1) is unlocked and the underlying partition (/dev/dm-0) is not mounted but it has a "busy circle sign" on it that will not turn off. The NTFS partition on the same drive mounts and accesses normally.
But if I try to unmount the NTFS partition, it says: "Unable to stop drive. One or more partitions are busy on /dev/sdb"If I try to shut down the computer, it is unable to shut down because (I assume) it can't shut down that drive either. So I have to just turn off the computer.fdisk states that /dev/dm-0 doesn't have a valid partition table [full output attached]fsck suggests: "Filesystem mounted or opened exclusively by another program?"ps axuf shows some processes running on /dev/dm-0 but killinghem doesn't release the drive either. [full output attached]I checked /etc/blkid.tab (suggested in one vaguely related thread) and there's no actual file only a broken link pointing to /dev/.blkid.tab (which doesn't exist). I tried deleting this link and rebooting but that didn't change anything.when I finally gave up my data as lost, I tried to format the partition (using Disk Utility) and it refused saying, "One or more block devices are holding /dev/sdb"
I installed DansGuardian. In order for it to work I set the system wide proxy. However it is really easy to get around DansGuardian by going to preference proxy setting. How do I password protect this setting so it requires a password to change proxy setting? Preferably a different password than the normal sudo password if possible. If not I at least want the sudo password protecting it! I run multiple browsers so doing it via the system rather than the browser made the most since.
Since August of 2009 I have been under attack by corporate Black Hats. I found a 105GB FAT16 Hidden partition on my hard drive. Seventy four percent full (78GB). What led me to this was the fact that I couldn't help but notice that my Internet connection was a revolving door that never stopped spinning. So I went looking for why.
I removed the hidden flag, and patched the partition, but couldn't open that thing no matter what I did. I tried for a month. The attacks started as soon as I stopped these guys from accessing that data. At this point we are 9 months into 24/7 attacks. I have interviewed with the FBI, and local law enforcement, but they are intent on making me out to be a conspiracy nut. I am not at all. All they wanted to do is quiz me on my computer skills. If I managed to draw the attention of a corporate security group they killed it.

I'm looking for a version of, or equialent to, Predator for Ubuntu 10.10. This program sets a USB drive as a key to the computer, locking it when removed. I've had no luck in finding an equivalent for Ubuntu, and the site does not have a version for Linux of any kind.
I got a dell inspiron 1501 laptop with a 80Gb sata drive what is the best solution to add data storage space for someone that love to have multiples operating systems at hand Note: I use mostly linux so I won't need to change my laptop for many years maybe ...
My parents bought a new hard drive for a laptop that I've owned for several years. It's much larger than the current one, so I plan on splitting it up to dual boot it with Ubuntu.I have no problem with partitioning a drive (I always keep a LiveCD handy), but my question is this: how can I go about moving the existing partition to the new drive? This is a laptop, so I can't simply plug the new drive into another slot.
Also, even if I manage to move it, will Windows still work on the new drive in a larger partition? I've had this laptop for quite a while, and I've lost the recovery discs that came with it a long time ago. I also have a lot of software without CDs to reinstall them with. This makes not reinstalling Windows a high priority.
Trying to install Fedora 12 using the 6 CDs. Trying to install on an older x86 box.Problem is that when detecting my hard drive, Fedora 12 recognizes it as a sda hard drive instead of hda hard drive. I have no SCSI connected to my computer what so ever. It's an old fashion PATA Western Digital hard drive.If I proceed with the install, Fedora 12 only installs 200MB of the OS from the first CD only. No options for additional software or anything.
