General :: Knoppix Data Recovery Ownership Permissions?

Jun 4, 2011

I use Linux but have a computer with windows I use for gaming. It died and put the hard drive into another computer and used knoppix to recover my files. I looked at the ownership of the windows files and the owner is knoppix. Now I am concerned that ownership will not work on my new Windows computer (when I finish building it, that is). Since I don't get into Windows much I have no idea what those permissions should be.

If I copy them with owner knoppix can I even access them in Windows to change the ownership to whatever Windows will accept? If I change the ownership before putting them on a CD with knoppix, can I write the CD? I will have to use the hard drive on the new windows box so will not have access to the files later (unless I also copy them to my Linux computer for safekeeping). At least I know the ownership changes to make with Linux.

General :: Windows Vista Password Recovery Using Knoppix?

Jun 6, 2010

I am new to knoppix. I actually have never used it. I was under the impression that I could change or recover my password on Windows Vista. I only have one user and it is the administrator. I am not exactly sure why it is no longer working. It is on a laptop and I have let others use it at times. don't know if someone may have changed when it was open at work or something. Every time I boot up and my user account comes up. I put in my password and it looks like it will log on but then comes back and says wrong password. I did see a way to do it with Windows 2000, and XP. Will that also work with Vista?

General :: Change Permissions And Ownership For NTFS Mounts?

Apr 19, 2011

I finally replaced my Windows with Linux.. However, I need to run applications and modify files that are on NTFS mounts. I am unable to change ownership, permissions, and groups on these files so I may modify them without having to copy. I have several times attempted to chmod, chgrp, chown, etc.. while logged-in as root user; however it is to no avail. The owner and permissions are still geared towards root. can I change ownership and permissions on NTFS files so I can modify them without having to convert/copy them over to ext4 or different file system?- Matbtw: I am using OpenSuse 11.4 and running Windows apps with VirtualBox (with Vista installation image). I still have Win7 on my computer (non-emulated) and I would like to keep some files on those NTFS partitions so when I occasionally need to boot into Win7 I can modify those files because Windows blows and doesn't support Linux.

Ubuntu :: Changing File And Ownership Permissions?

Jan 1, 2011

I installed Ubuntu from the alternate cd a few days ago to save space and resources on a very old laptop. (install command line, then add what I wanted) But I have struck an interesting problem with file permissions. Various programs like synaptic, leafpad, pcman, Banshee, all require I enter the root password to execute them (or sudo command from terminal). I want to change synaptic from root ownership to sudo and leafpad etc to execute without using the sudo command in terminal. I could get comments on the commands before I execute them in terminal and if I am introducing a security problem, as I am still learning bash. $ sudo chown sudo:sudo synaptic

I would still be asked for my sudo password before being able to open synaptic? As in standard Ubuntu instead of root password.$ sudo chmod 777 leafpad pcman Banshee All users could open these programs from the menu? I have my admin account and a general account which I use for everyday things like surfing the net and listening to music.

Ubuntu :: Ownership & Permissions Change When Files Burned To DVD+RW?

Jan 18, 2010

After burning files to DVD+RW, the owner is changed to root, and all permissions are read only. I want to periodically open these files, update them, and save to the DVD again, but I no longer have permission and cannot change the permissions since I am no longer the owner. I tried sudo commands, but get responses "Read only file system". I have erased and reformatted the DVD and started over but get the same results.
I have Ubuntu 9.04, and have tried Brasero and Nautilus and get the same problem. Am I using the wrong kind of DVD/CD?

Ubuntu :: File Permissions / Ownership - Even Root Cannot Change

Aug 30, 2010

I have been VERY lucky and managed to restore from a formatted ext3 /home/ partition. I used testdisk to reset the original partition which had had nothing done to it since formatting(!). However some of the file permissions are a altered and I cannot change them. I have tried "su chmod" and even temporarily enabled the root account itself and tried to alter the ownership/permissions from root 'proper' without it helping.

Here is an example of the output of ls -l
drwxr-xr-x 2 martyn martyn 4096 (date) (time) sponsors
?-----S--T 63231 92820383 44090688 4286824785 (date) (time) order.xls

The first line looks like a normally formed output and indeed is readable. The second line looks corrupted and I don't have a clue how I can reclaim this - or even if it is possible. Should I count my blessings most of my files are intact and leave those be?

Software :: Script For Checking Ownership / Permissions Of Directory

Oct 14, 2009

I am writing a script that is checking the ownership and permissions of a directory. If the directory in question does not have the correct ownership and permissions, the script will run the appropriate commands to give it the correct settings. The if...then...else syntax. The idea here is the following:

Code:
If <directory> no eq = <ownership root:root> && <permissions 755>
then chown root:root <directory> && chmod 755 <directory>
else exit
fi
What would the correct syntax be for the If line of the loop in question?

Software :: Version Controller (keep Track Of Changes) And Permissions / Ownership

Aug 1, 2010

I run the servers hosting an intranet, a couple of services and an external websites for my club at university. I'd like to back up all the config files to some version control system to keep track of changes, in case one of my colleagues breaks something. The idea is to keep snapshots and then just roll back the required file in case something happens.

Now to the main issue: How does a version control system handle file permissions and ownership? Does it keep them? Does it set the permissions of the user who committed the last change? These are important questions as we have multiple daemons with different users...

General :: Data Recovery For Overwritten Partition

Jun 27, 2010

While attempting to install FC12, Anaconda took it upon itself to overwrite the partition on my backup disk. Now I need to figure out if there's a way to get at least some of my data back. If there's a better place for this question, please let me know and I will happily move it. Using Linux since 1993, other Unixoid systems since 1986. I bought this machine back in 2004 or so. It was a pretty decent machine back then, but it's showing its age now: 370Mb of RAM, 2 hard disks with 80Gb and 120Gb (I don't think the other specs are relevant, but just let me know if I'm wrong). In a fit of insanity, I decided to install Gentoo on it. Don't get me wrong: I love certain things about Gentoo. But the constant fiddling that's required, while it can be fun at first, gets old kinda quick.

So various and sundry things have been going wrong with it here and there (CD-ROM, sound card, etc ad infinitum), and, finally, it wouldn't even load X any more (almost certainly some final Gentoo update which broke something) and I said "screw it, I'll just put Fedora on it." This is what I use at work, and plus I have a good friend who has far more patience with admin stuff than I do and Fedora is what he knows. So, last night, I pick up an FC12 CD that I have lying around and decide to finally just reinstall the whole thing. I went so far as to buy myself a Passport USB drive, 319Gb, and have been backing up up all my stuff very regularly to that drive. I go through one final cycle of backing up and verifying before I start the reinstall.

So my drive is solid, and contains everything I could possibly need (and probably quite a bit of stuff I don't). After booting into FC12, I used Palimpsest to explore the partitions on the existing hard disks. Not sure which was which, I mounted the Passport, where I have cleverly saved a copy of my fstab. Using this, I can see which of my partitions were /boot, /, /home, etc. Most of my personal data has been put into separate partitions so that I could reinstall without blowing away the data. I hope that I can do that there, but, if I can't, no matter: I have a backup. I find some bits of empty space and delete a few of the partitions and recreate them, consolidating the empty space. Still confident in my backup, of course.

So I run Anaconda. Nothing happens. Eventually, I figure out that it won't run the graphical interface because I don't have enough memory. I can use the text version, no biggie. It gets to the part about the disks. I tell it which hard disk to install itself onto. For some reason I think it's going to pop up and ask me about the existing partitions and whether I want to keep them or rewrite them (maybe that's a previous version of Anaconda? or a different installer altogether, who can remember). It does not. It babbles something at me about LVM (which I've personally never really used before), and then promptly locks up. Obviously standard Fedora on a low-RAM machine like this is doomed to failure.

I poke around on the Internet, and I eventually stumble on the Fedora "spins" and select FC13/LXDE. Hopefully this will have better luck. Reboot with the new CD, take a look at my hard disks. It has completely overwritten the old partitions, replacing them with LVM partitions. But not a big deal: I have a backup. Take a look at the Passport. Its ext2 filesys has also been replaced with an LVM partition. Proceed to beat head against wall. So, obviously what happened is, since I (foolishly) had the backup drive mounted at the time I ran Anaconda, it assumed I wanted it to take over that drive as well, and just formatted everything it could lay hands on as LVM. It certainly never asked me my opinion on the matter.

But, fine, I shouldn't have had it mounted. The question is, what do I do now? My first, panicked instinct, was to just set the partition type back to 83 (I believe LVM is 8E), which I did (using cfdisk). That might have made it worse; I dunno. But I'm pretty sure I haven't written anything else to the disk since then. I've tried testdisk (nothing useful; although it can seemingly find the underlying deleted partition, it won't actually do anything with it), and a bevvy of Windows Linux recovery programs (Stellar Phoenix, DiskInternals, Raise, and R-Linux), all of which were completely useless except for R-Linux, which scanned the disk for eight hours and was still going when I had to interrupt it (I may come back to that one, but so far it doesn't look too promising).

My primary problem is that I can't make an image of the disk because this little Passport is the biggest hard drive in the house. I would certainly feel better if I could image everything off it and then play with the image. But, of course, it doesn't matter that very little of that 319Gb was actually being used: I still need 319Gb worth of space to make an image. I ordered another (larger) Passport, which should be here Wed. Once I have that I believe I can do something like so:
Code:
dd ifs=/dev/sdX ofs=/mnt/bigpassport/smallpassport.img bs=512
Right? Then I can muck about with that image in some amount of safety.

Of course, I also have the original hard drives, which are not so large. testdisk can identify the original partitions on those too, but, again, won't actually do anything with them. If I could find something that would image just the partitions I care about, I could probably save those as well, but I don't have any other external hard drives with 120Gb of space free. Can I somehow take the info that testdisk is giving me about those original partitions and use dd to get only that part of the image? Are there other recovery tools I haven't considered? I have a Windows (Win7) laptop, a Linux laptop (FC10, I think), although its power cord is flaky so it's not too reliable, a smaller Mac, a really old Windows box (XP on it, I think), and this formerly-Linux box, which I can only boot off CD's at this point. There's nothing on this disk worth the 500 bux that professional data recovery would charge me, but it's worth a day or two of my life to try to get at least some of it back.

General :: Data Recovery - No Valid Directory

Nov 15, 2010

I was trying to set up a partition on my netbook's hard drive, and foolishly forgot to backup my home folder. Now, Ubuntu (10.04, btw) won't boot. It allows me to get into the manual recovery shell, though. Now, I'm perfectly willing to reformat, but first I'm hoping I can recover the files from my home folder without having to take my netbook to the ridiculously overpriced computer repair centers in my area.

I have an external hard drive, but when it's plugged in during the recovery shell, it won't register as being a valid directory. I know the commands to copy or move a directory, but without my external reading as a valid directory to move my home folder to, I'm kinda stuck. Is there any other way to recover the contents of my home folder without having to go to a computer repair place? Neither of the ones in my area know much about linux at all, and I really don't want to have to pay $80+ to have someone else recover my home folder.

Software :: Recovering Data From MD Array (using Knoppix)

Jun 2, 2011

I had a major OS crash (Gentoo) maybe 2 months ago and completely neglected my system. Now I want to recover all my mirror raid data back so that I can restore the system. My plan is this:

1) copy all data so that I can have a backup
2) rebuild system with some HW upgrades

First step is to get the data out. I managed to boot with Knoppix and I have full access to my ext2 partitions. My mistake was to create the mirror partitions and these are not working now. I copied my /etc/mdadm.conf into /etc/mdadm/mdadm.conf in Knoppix and then tried to start the services. This is what I got:

knoppix@Microknoppix:~$ /etc/init.d/mdadm start
knoppix@Microknoppix:~$ /etc/init.d/mdadm-raid start
Assembling MD arrays...failed (failed to load MD subsystem).

I can see the partitions:

[Code]......

These are my current ideas:

1) Can I change the filesystem type from mdraid to ext2 or ext3 safely?

2) How can I mount these raid filesystems so that I can copy my data?

Software :: Failing HD And Knoppix Not Seeing Data Partition

Mar 11, 2009

The HD in my Sony Vaio suddenly won't boot and all attempts to repair it have failed. All I care about at this point is recovering the data, so I tried to access it with Knoppix. After a "dirty drive" error message, I was able to view the contents. The problem is that it seems to only be recognizing the Sony recovery partition and not the Windows/Data partition. The drive size is detected at less than 10 gigs when it is actually 250GB. I am completely green when it comes to Linux. How can I access the data partition so I can back it up to an external USB drive?

General :: Data Recovery From External NTFS Disc?

Mar 19, 2011

I'm using Ubuntu 10.04 and am trying to use it to recover data from a failed External HDD (NTFS).

The drive failed with an accompanying smell of electric burning and subsequently was not recognised by Windows. It would recognice the enclosure, but told me that the drive had to be reformatted.

I removed the drive from the external enclosure and hooked it up to my PC with a power cable and USB to SATA connector. I can mount the drive in Ubuntu (eventually) and I've learned enough about BASH to navigate through the files on the drive.

Those that I can access I am able to copy across to my internal drive (VERY slowly, but it does do it) but a lot of the directories show up with an Input/output Error when I run the ls -l command.

Is there any way for me to be able to access these files or to recover them? Should I be trying a different technique rather than just attempting to access and copy the files?

General :: Data Recovery On HDD - Command Line Prompt

Feb 11, 2010

I installed Fedora 10 on a pc I built from a barebones package, I have had no problems over the past couple months until recently. When I start up the pc the OS lags on a black screen with the cursor blinking. I have searched forums but I guess since I am a newbie I am still lost in the translations. What I am trying to do is save my files that are on the pc to a DVD-RW or my external hard drive before I have to reinstall the software again.

My questions are as follows:
How can I locate the files on the hard drive? When I have the bootable cd-rom inserted I am unable to locate the HDD. How can I transfer my files using the command line prompt? Finally, is it possible just to upgrade to the latest Fedora without losing my files and going through the data recovery process head ache? Or can I reinstall the OS and not lose my files?

General :: Recovering Data From Ext3 Partition With Hardware Errors - Recovery Required On Readonly Filesystem

Jan 10, 2010

I have an external 3.5" USB 250Gb HDD which is showing symptoms of hardware problems (repeated /var/log/messages errors of "reset high speed USB device using ehci_hcd"). This was originally plugged in to my NSLU2 running Debian Etch. I have just installed Ubuntu Desktop 9.10 to a spare Pentium-3M laptop and was hoping to copy the contents of this HDD to a fresh drive. However, I cannot mount it even read-only; mount -o ro /dev/sde3 /mnt/disk fails, and the /var/log/messages error is "recovery required on readonly filesystem", "write access unavailable, cannot proceed". I cannot understand why mounting a disk read-only should require write access. Following advice I googled elsewhere, I tried running mke2fs -n /dev/sde3 to try to list the alternative superblocks - but once again I got the error that the device was read-only. How can I go about accessing the data on this disk?
