I was asked today if it was possible to encrypt a CDROM just as you would a disk - and I drew a blank. The question came up discussing a database we maintain with a lot of the organizations financial info plus ersonal membership data. Can I create and mount an encrypted CD? What are the performance effects? Is it a viable one to two year archive medium? The plan is to store period off-site backups and I can't get a grasp on the feasibility.
I've never encrypted a disk before; I'm following the Arch wiki (I'm a newbie, basically). Should I try and encrypt my swap partition (I've got 512 MB RAM, 1 GB swap)? Ideally, I'd like to make it so it's not feasible for someone (even a very skilled someone) to access my files (and system -- I'm encrypting /), but still make it fairly fast and usable for day-to-day operations. If it matters any, I'm using JFS.
There was an option during installation of 10.10 to encrypt the hard disk (or was it only the home folder?). I thought, hmm, I should probably do this, but I'll decide later, thus, installed 10.10 without encrypting the hard disk.Now, I want to encrypt the hard disk but don't see anywhere in the System Preference or Administration where I can do that. Am I missing it? Or how do I do this now?
I highlight text in an email, "cut". Right click KGPG, encrypt clipboard, select my own public key, go back to email and "paste" and it appears in plaintext! WTF I tested it in kwrite too. Wrote the text "hello world", highlight, cut, encrypt clipboard, select my public key, paste, "hello world" appears! WTFx2
what i want to do is encrypt my entire home folder or at least make a new private folder where everything is encrypted. Previously i had tried to use truecrypt but it didnt work well on opensuse 11.2. Anyone here have issues with truecrypt with opensuse 11.2?
I formatted a external 160 GB HDD (Lacie) with EXT3 and encrypted. The formatting went perfect. When I stick it into the USB slot, it is recognized and mounted by HAL. Hal asks me the password and then everything seems ok. But I have no write access. Only root has. I would like to use it to store my user data, externally, but encrypted. How can I set the write permission to make this possible? Why does HAL attribute the write permissions to root, even if I have given the password as user?
I am looking for something like Ubuntu does (or claims to do :-) ): encrypt the home folder so that, once done, you can even forget that it ever was encrypted.
I have had a quick look to encfs, and to the KDE "right click menu"; but, when dealing with folders, it seems that they pack them into a single file and then encrypts it (if I have correctly understood).
So, what is the way of encrypting the home folder (and subfolders) as Ubuntu does? (and so that you can completely forget afterwards)
I created a thread about a problem a I had with my hard disk clicking whilst idle little while ago and I may now have stumbled upon a possible solution. The strange thing with the problem is that Ubuntu/Kubuntu didn't cause this problem but Opensuse 11.2 does.
I installed Fedora 13 to have a glimpse of what all the fuss was about and noticed that I had the same problem (hard disk clicking whilst idle ~ every 20 secs or so). Now there's a wiki on this subject and a few bug reports: [url]
Problem Description
Some ATA harddrives perform very frequent head unloads under Linux significantly shortening their lifespans. Root cause
The inactivity timer for head unload is configured too aggressively either via ATA APM (Advanced Power Management) feature or other non-standard means. Such aggressive settings are very fragile to changes in IO pattern and under Linux many such drives unload their heads only to re-load them shortly. Note that this relentless unloading/reloading cycle can also be triggered under Windows by installing programs which can alter the IO pattern (e.g. certain vaccine programs which runs in background).
Now two of the listed models with this problem are basically identical to my model (Dell Inspiron 1520) and basically share the same hardware: Dell Vostro 1500 and XPS 1520.
The workaround listed is to:
set APM to 254
Furthermore, there is a script: Storage-Fixup which can also be downloaded from opensuse software search. Indeed there is a report of this for a Vostro 1500: Gmane Loom
The report suggests looking at: Disk Power Management - openSUSE which lists a method to create a configuration file to management disk power management:
My question is whether I could download the storage-fixup rpm [url] has a description of it and it can be found: Software.openSUSE.org) and install it to (hopefully) solve the issue or should I follow the method given in: Disk Power Management - openSUSE
My dual proc, dual core Opteron MSI Master2FAR motherboard failed, and I try to boot a disk, used on this board as boot disk, on an Intel based Gigabyte GA-965-DS3. Both systems are x86_64 architecture.
The OS is on both systems is openSUSE 11.1.
On booting the disk on the Gigabyte, the disk is seen correctly by the BIOS, but not by the OS, and there is no /dev/sdX; no /dev/disk/... either. I am taken to a login shell from the ramdisk.
When I just mount this disk on the Gigabyte (booted with the Gigabyte's original boot disk) everything seems fine. No suprise to me, since the disk was fine, and was unmounted gracefully and physically taken off the MSI before the board failed.
I think that the cause lies in the fact that the harddisk controller on the Gigabyte is different from the MSI, and the driver for that controller is not available at boot time.
I have two questions:
- is my assumption correct, or is something else going on?
- if I am right, is there a way to get this disk booting on the Gigabyte (or on another system, for that matter)?
You might want to ask why I want to boot this disk on the Gigabyte in the first place, since I can mount it and see all data on it. I have a reason for that, but telling that story would make this topic too long, and it's too off-topic. Most certainly I will get to that in another topic.
I've recently added a new hard disk and due to mother board controllers this new hard disk is known as sda.Before that my boot partition was /dev/sda3 and know this changed to sdb3.Whenever grub menu appears and I choose opensuse,it can't find /dev/sda3 .It seems that I should edit menu.lst or change boot loader parameter.something like root (hd1,2).But I don't how I can do this with opensuse boot loader.Though I could do this with CentOS easily.
I would like the ability to right-click on a file and encrypt it, but after genning the PGP key pair in seahorse that option doesn't exist on the pop-up menu.
I'm a bit confused about how ssh encrypts connections. I've read a few articles on ssh and they talk about 'keys pairs' (that is public and private keys) on the server and client computers. However, ssh doesn't seem to use these keys for encryption. What are the keys it uses? This question occurred to me when I was trying to make a remote login to an Ubuntu machine. From a remote login perspective, I haven't generated keys on my client machine and haven't enabled key based logins in ssh. (I use the default password based login). If there aren't any keys on my client, then how does encryption work?
I set my storage hard disk to auto-mount at start up, using fstab options, but sometimes (when my computer has been on for awhile) the storage hard disk will unmount by itself....any ideas?I have already tried replacing the hard disk multiple times, and I switched from Kubuntu to Opensuse. (partially because of this).This occurance only appears after I have had the hard disk for awhile. (Western Digital Caviar Green series) I do plan to upgrade to OpenSuse 11.3.
Recently I was working on something on my windows partition (on the same HD as opensuse), and all the sudden windows stopped working and I got some bad sectors on my HD.
Now, my opensuse installation is on the same HD as windows, but I need to get rid of that HD soon because it's starting to get worse (and I think opensuse is randomly crashing because of it).
Is there any way to transfer my opensuse parititon/os to another hard drive?
With the gpg command I used to encrypt files so they saved as plain text (the encrypted files were viewable in a plain text editor though were a encrypted nightmare)
I just forget the option in the gpg command to do this and I can't find it in a hurry either in the man file
I'm currently writing a simple script which uses luckyBackup to backup my /home directory to /tmp. I then want to tar it, encrypt it with gpg and move it onto a usb stick. My question is that suppose my hard disk died and I needed to restore from this USB backup, would I still be able to decrypt the file given that I would have lost gpg keys etc when the disk died? (I would still know the passphrase though). Should I be backing up gpg files separately?
have been trying for many hours to install Ubuntu 9.10, on a system that already had 9.10 installed on it at one point (so I know it should work!) I am using an alternate install, from a USB thumb drive. I use the alternate so I can encrypt the hd. Everything goes smoothly until I am to select extra packages to be installed. The only package I select is the ubuntu-desktop, and around 80% progress, or so, it fails. I then try and complete the base install, and then login to the command prompt and install there:
sudo apt-get install ubuntu-desktopIt then requests the Ubuntu disc, which of course I don't have. It has a landline internet connection. Do I need to configure something to tell it to look to the mirrors to find the desktop? Or, should it have been included in my iso image originally
I use this line to line to archive and password protect my files (with zero compression):7z a -p -t7z -mx0 ~/Documents.7z ~/Documents In the attached picture, I notice there is a check box to 'Encrypt the file list too' via the GUI 7z method. How could I add this option to the above 7z line?
Also I think rar allows you to 'Encrypt the file list too'. Could someone also give me a rar line similar to 7z a -p -t7z -mx0 ~/Documents.7z ~/Documents but that has the 'Encrypt the file list too' feature added?
I just bought a new Kingston DataTravler G2 16GB usb drive and was wondering if it was possible to encrypt the entire device.As in, it would require a password before even seeing any files. If possible I'd like something that works on all OS's but if not any suggestions would be great.
I have a ext hdd..seagate go. And my 14 yr old son likes to get into it without asking me; of course i dont care when he asks but i don't really want him to get in there and erase anything. I am about to leave for training for 18 weeks with the military. Is there a way i can "secure" the drive for the amount of time that I can't take it with me?
I need to temporarily store a file containing sensitive data in a public server, in a secure way. I think that encrypting the whole file would be much more secure than creating a passworded .zip encrypted file, because they could be subject of brute force attacks. Attacking a whole file of unknow format is harder, I think. I thought of something like the command:
Code: $ programidontknow --encrypt mysensitive.file --output-file mumblerumble.file then the program asks interactively for a password) $ ls mysensitive.file mumblerumble.file
So I get one file that may look like junk. I tried to search how to do it with GnuPG. But it seems that GnuPG needs much configuration I dont want to do. I simply want to type the password one time to get the file. It doesnt need to retain any configuration for what I want to do. In similar scenario, I would want to do this on a machine/account that is not mine.
