Ubuntu :: How To Wipe Sensitive Data
Jun 12, 2011
I accidentally made a mistake of deleting the data I was suppose to shred. I cut and pasted sensitive documents from my external hard drive into my laptop. I want to shred those documents from my external hard drive but since I already did a cut/paste command those files are no longer accessible from my external hard drive. Is there a way I can fix this?

I recently used D�j� Dup for the first time. I chose to backup my home folder and most dot folders (do most of you backup all your home dir dot folders?). Even though D�j� Dup uses gpg, is there any sensitive data stored in dot folders within my home directory?
BTW, I did an incremental backup up to an older D�j� Dup backup folder on my NTSF external HDD and got an error. Is this because it is NTFS? I then did an incremental backup to a backup folder on my PC (ext4) and got no error. In the picture attached, would that setting mean the backup will continue to grow to a huge size? Would it be better to keep backups for a week?

Question about the bug reporting system that I think is called ABRT Struggling with F15 and want to file a bug report, but the backtrace thingy says I should remove sensitive data first. Obviously a good idea, but the report is full of what to a non-programmer looks like gibberish - things like what I guess are hexadecimal numbers or memory addresses, none of which I understand. Can any of that incomprehensible stuff contain sensitive data, like encryption keys or anything someone would need to crack a machine? If I remove all of that then the bug report will be pretty sparse.
(Same question applies to SMOLT - machine profie report - as well) Or is "sensitive" just about the human readable data in the reports?

My company needs to send sensitive data across to another company, 800gb of .dpx. The way I have thought of is:
E-Sata/1TB WD black.
True-encrypted/ hw accelerated aes (3x machines being built with 2600k)
Sha1sum on each file.
The main goal is to make sure that
1. The files that were transferred off the server onto the drive, are exactly the same.
2. Secure.
3. Fast.

Is there a script I can use to send a command VIA terminal to wipe an entire machine of data? If for example there is an intrusion valuable data can be at risk, it would need to be erased.

The sort utility in Ubuntu 10.04 (Lucid) always sort by case-insensitive, just like if you specify --ignore-case to it. The two sort just give the same result:
[Code]....
But sometimes I want to sort by case-sensitive, so the upper-case letters come first, then lower-case letter.

The touchpad on my Lenovo Z560 is to sensitive. I went into the mouse setting and adjusted the pointer speed sensitivity as low as possible but I don't see any difference. The lightest touch will move the pointer. I saw where some have modified the xorg.conf file but I can't find it in Ubuntu 11.04. From what I could find with Google this laptop uses a Synaptics touchpad. I installed Gpointing-device-settings and was able to change the speed but not the sensitivity. How can I make the touchpad less sensitive?

Anybody know of a way to search only for similar case sensitive files? By which I mean doing a wildcard search across a drive & the only results are like: Abc.txt abc.txt VID_001.avi Vid_001.AVI .. etc.
I've already tried searching the forums & google but the closest I've found is regarding files with increasing numbers (music_001.mp3, music_002.mp3, etc), which doesn't quite fit with my issue, as they would be seen as different files on a case insensitive OS.

I have a sh-tty B/G wireless card that does 500mw according to iwconfig. I also have a nice little panel antenna on this card that does 7dBi. This rig picks up a lot of signals and that is really great. However I am experiencing a problem. I am able to Internet browse on non-encrypted networks as long as the wireless manager shows a full four bars. However, if I try to connect to a three bar network, I will not be able to browse the Internet. I have a solid lower level 3 bars, I'm assigned an IP addy, but I get absolutely no throughput.
So, I think this has something to do with receiver sensitivity. In G mode, this card does a lousy -65ish or so at 54 meg. So what I'd like to do is drop to 5.5 or 11 meg B because at 5.5 meg or 11 meg B, the card does a much more acceptable 90+ sensitivity.Does anyone have the command string/app for this? I would like to force a card to operate in no better than 802.11B@5.5meg rather than having it auto select 802.11G@54meg.

I recently upgraded to Fedora release 12 (Constantine) and noticed that sort is no longer case insensitive.
echo -e "ba
a
A" | sort
a
A
ba
I think it should be:
a
ba
A
The -f flag does not change anything. I have sort (GNU coreutils) 7.6.

I have a SONY 52x DVD Writer in my Desktop. Initially it was okay.. For the past 2 months or so , the DVD tray is super sensitive.. When I press the "Eject" Button , it comes out and immediately the next second goes back in..Also I face great difficulty in loading a CD/DVD .The moment the DVD touches the tray , it sucks the tray back in.
As a result , I am not able to position the DVD, most of the time it gets stuck ..I cannot manually stop the tray from going in as I guess the spring for the tray will break.Should I replace the drive? Apart from this mechanical issue , the drive reads and writes properly.. I like Drives which have separate open and close buttons (not the ones which you push from the front)

I'm running a Fujitsu Lifebook T5010 with Linux Fedora Release 12 and the mouse is way too sensitive, jumps all over the screen when I touch it, especially if 2 fingers touch at the same time. I've tried all the system settings and nothing helps. It works fine with Windows XP Professional.

I should note that I tried the Ubuntu 10.04 and 10.10 Live CDs and have experienced this in version 10.10's Live CD. I guess that narrows the problem to GNOME? Basically, moving the cursor horizontally takes less effort than moving it vertically. It feels as though there are separate axes for sensitivity and I don't know how to configure them. how to make it be normal again? (In Lenny, it was perfectly fine.)

Some of my files and directories were mysteriously disappearing and some of my shell scripts were failing after the upgrade to Fedora Core 12. After some debugging I found out that file name globbing is no longer case sensitive in Fedora Core 12, that is
rm -rf [a-z]*
now also trashes all files and directories starting with [A-Z], which explains the removed files and directories
and
ls [a-z]*
now also includes files and directories starting with [A-Z], which caused my shell scripts to fail.
Is this a bug or a 'feature'?

I'm selling my Dell Mini 10 that came with Ubuntu on it. I never really used it much, and the only sensitive things on it were some PHP files with MySQL passwords that I can change on the server if need be. I'm not familiar with command line at all, so I'm having trouble figuring out the best way to wipe the SSD. I already reinstalled the OS using the recovery disk from Dell which said it would 'delete' the contents of my hard drive. I'm not sure if the job it did is suitable. What's the best way for me to make sure my data can't be recovered? Is there anything with a GUI I can download to help with this?

Today I ran
aptitude update && aptitude safe-upgrade
Like I regularly do, and I see these two packages need to be upgraded:
login passwd
Since these packages seem kinda security-sensitive I would like to know exactly why I would need to upgrade them. I checked Debian's security list but couldn't find anything relevant, and the links to the changelog for both packages are broken:
The requested URL /changelogs/pool/main/s/shadow/shadow_4.1.4.2+svn3283-2+squeeze1/changelog was not found on this server.
Where can I see what is changed in these packages so I can safely upgrade?

I have a netgear WG11T. I'm using the drivers through ndiswrapper, and connecting through wifi-radar. Everything works fine, but if I take out my WG11T and then put it back in, it is not recognized; in fact, nothing in that port is recognized, until I reboot.
How can I make my usb port less sensitive?

I'm logged in as root and want to run Add/Remove Software (Package Installer) but get the message telling me
Code:
Running graphical applications as a privileged user should be avoided for security reasons. Package management applications are security sensitive and therefore this application will now close.
How must I install applications? Surely the world is getting paranoid with all this hackers and viruses, because with every new version O/S, the security features gets more and more; up to the point that you can't fricken do and play around with your pc as you would.

I have a acer aspire 8735G-6502 this bad boy [URL]: Acer Aspire 8735G-6502 18.4-Inch Widescreen Laptop: Computer & Accessories I am trying to figure out how to configure the touch sensitive volume level control. It works somewhat, but only increasing volume. Xev does a strange job detecting the key codes, and assigning keyboard short cuts does the same thing. In fact when moving ones finger in a downward, volume decreasing motion it picks up only strange upward finger motion.

however I've managed to hash up the iPod database using gtkpod, as it seemed to come up with some error, which it quite often seems to do. It all semed normal unitl I ejected the device, as, upon ejection, it appears to not have any tracks or videos on, only games, however I can tell you that all the tracks are still there. The only other issue is my windows box is out of commision, and my laptop doesn't have enough space to hold 80g of music, and need the iPod soon for many presentations, which rules out sending it back to apple.

I have installed Ubuntu within xp abt 6 months before and till now im running dual boot with grub loader. I guess its Ubuntu became the primary OS but not sure. I need to figure out 2 things.
1) Which one is the primary OS. Since the grub loader is showing first, is it ubuntu? or since I have installed ubuntu alongside xp, is it XP? which one gets affected if i format/remove c: drive.
2) And second I would like to format xp and install windows 7 without losing my data, hard drives etc.
Is it possible? I want to just format my windows xp installed c: and want my ubuntu remain untouched, coz I have made many manual configurations and installed many softwares and made my ubuntu more stable than windows, so that i will continue to use ubuntu grub loader henceforth for ubuntu and windows 7.

I recently used a flash drive to try MeeGo on my netbook. Unfortunately, the application I used to write MeeGo to the flash drive created a new partition in a rather unusual format. The Ubuntu disk utility can't delete the partition, and GParted can't even see it. How can I completely wipe the flash drive from Ubuntu? I'd prefer not to install any additional software.
