Ubuntu :: Deleted User Main Folder - How To Restore Using Root Shell
Apr 14, 2011
I have system that was cloned from another system hence the user was same in both computer. I changed the computer name - to TANU. Then I added another user - BANU. I gave admin rights to second user. Logged out the first user DON- who is now only the desktop user. Before deleting the account through users and groups - I deleted the folder DON from home folder. I restarted the comp. unable to login. I had created automatic login for both users. How to restore the folder DON while using root shell.
By naming one of my folders wrong I thought I don't need it anymore and pressed delete button while holding shift. Is there any way I could get that folder back? (I'm actually looking for the file inside that folder - .conky config file to be more precise) I've tried scalpel and extundelete, but none of them worked.
My /boot folder is deleted by an unwanted mistake. I'm using F14 x64. I have updated my OS and I also installed more than 2 GB packages and It is very difficult for me to re install Fedora. Is there any way to fix this problem with out re installing Fedora?
Somebody deleted a folder from /opt, now how I to know who did it? should I login to every user from root and check the history? or there is better and easy solution?
I messed up, and was forced to reinstall the system. my user data ws stored on another partition /home/Andre I installed as a new user "test" How do I make a new user "Andre" such that it uses /home/Andre ?
I accisentaly deleted my root user on lenny, because of a gamepanel...Do you know how to re-create it?I am logged in SSH with the root user, so i'll try to re-enable it when the work will end in the window.Edit:User now re-created, he doesnt have the root rights
I have a Macbook 2,1 since 2007. Last week my hard drive just died, so I decided to replace it with a new one, no problems with that. The problem came when I had to install an operative system, because my DVD drive has been broken for a year and a half now. I know we can easily install MacOSX from an external usb drive, but I don't have a big enough pendrive at the moment. So I went for Ubuntu. I have managed to get an Ubuntu 10.10 live usb stick working like charm, if anyone is interested. I just downloaded the latest i386 iso and followed this advice by pxwpxw for the 32bit EFI.
The only thing I had to change in the boot.cfg was the name of the iso and -very important- changed initrd.gz for initrd.lz. The live usb works great. But I decided to do an installation on the hard drive. I installed it using the whole hard drive and didn't get any errors. But when I boot the macbook it doesn't detect anything. I guess I need an EFI bootloader or something to make it work. I've tried to follow this guide but it seems to be intended for someone who already has MacOSX and the Ubuntu installation working. I just want to install a bootloader or whatever I need from the "outside" (from the live usb I'm using). I tried to just throw reFit into the main hard drive's root folder but it doesn't work. I think that maybe creating an HFS+ partition and installing reFit in it may work, but I don't think I can create that kind of partition from the Ubuntu usb and I also need a working MacOSX to run the enable.sh. I've also read of elilo but I've seen that it hasn't been updated for 3 years
Or would this sacrifice security in some way? I've been using root only, and am ready to have a seperate account now. It's the dotfiles for GUI apps that I'm concerned about:
Code: -rw------- 1 root root 98 Feb 13 16:23 .Xauthority -rw------- 1 root root 6392 Feb 12 18:13 .bash_history drwx------ 5 root root 4096 Jan 13 17:47 .config drwxr-xr-x 4 root root 4096 Dec 29 21:36 .fvwm drwx------ 4 root root 4096 Nov 7 19:55 .mozilla -rw------- 1 root root 218 Jan 26 10:04 .recently-used.xbel -rw------- 1 root root 98 Feb 13 16:23 .serverauth.17096 drwxr-xr-x 2 root root 4096 Dec 25 12:42 .tuxcmd drwxr-xr-x 2 root root 4096 Feb 12 17:25 .xine
I need sudo for www (apache) user to run a shell script('ip.sh' contains iptables rules) from cgi-bin directory via browser using a per script. I edit sudoers( www ALL=(ALL) NOPASSWD: ALL ),but when run the bellow command that's with err:
# sudo -u www sh /srv/www/cgi-bin/ip.sh
iptables v1.4.4: can't initialize iptables table `filter': Permission denied (you must be root) Perhaps iptables or your kernel needs to be upgraded. And:
Is there a non-root shell command that can tell me if a user's account is disabled or not? note that there is a fine distinction between LOCKING and DISABLED:
LOCKING is where you prepend ! or * or !! to the password field of the /etc/passwd file. On Linux systems that shadow the passwords, this marker flag may be placed in /etc/shadow instead of /etc/passwd. Password locking can be done (at a shell prompt) via password -l username (as root) to lock the account of username, and the use of the option -u will unlock it.
DISABLING an account is done by setting the expiration time of the user account to some point in the past. This can be done with chage -E 0 username, which sets the expiration date to 0 days after the Unix epoch. Setting it to -1 will disable the use of the expiration date.
The effect of locking to to prevent the login process from using a supplied password to hash correctly against the saved hash (by virtue of the fact that the pre-pended marker character(s) are not valid output character(s) for the hash, thus no possible input can ever be used to generate a hash that would match it). The effect of disabling is to prevent any process from using an account because the expiration date of the account has already passed.For my situation, the use of locking is not sufficient because a user might still be able to login, e.g. using ssh authentication tokens, and processes under that user can still spawn other processes. Thus, we have accounts that are enabled or disabled, not just locked. We already know how to disable and enable the account - it requires root access and the use of chage, as shown above.To repeat my question: is there a shell command which can be run without root privileges which can output the status of this account expiration info for a given user? this is intended for use on a Red Hat Enterprise 5.4 system.The output is being returned to a java process which can then parse the output as needed, or make use of the return code.
I'm using ubuntu server 9.10 for a home build NAS. Everything is working great just have one more thing to figure out. I have Samba set up to access my files and I set up a recycle feature so anything deleted will get moved to a Recycled folder. (I learned this the hard way after hitting delete key by accident while browsing the shares in windows. Lost 100 GB of data)
Now it is for the most part working but the permissions on folders isn't getting set right. If I delete a file in a share I can go to Recycle bin folder and delete the file for good. But if I delete a folder I can not access that folder to delete or restore from the Recycle bin folder. I have to chmod the folder before I can do anything with it. Anything I can change to get folders deleted via windows to have the right permissions when it is moved to the Recycle bin folder?
I need to unmount my primary partition /dev/sda1/ to perform a FSArchiver restore, however when I try to umount the partition it tells me I can't unmount a partition that is in use, how do I fix this?
I deleted my main panel at the top of the screen. I created another but I am having trouble getting a few tools back on it. Mainly the 'Places', 'Administration', and 'Settings' options (I think that I worded them correctly). I of course went into 'Add to panel' but I can't seem to find those tools.
I accidentally deleted my top panel and am in the process of restoring it. The last thing that was there which is not now is the quick link to Ubuntu Help. It is installed on my PC but I cant find it.
I deleted my panel (where you can see running programs, show desktop shortcut). I know - its stupid to delete panel, but I wanted to try it out. How can I get it back?
So I transfered a few folders with videos in them to the public folder on an Ubuntu 10.04 laptop I have from my Ubuntu 10.04 64bit laptop. When I wanted to delete the folder I didn't have permission so I ran "gksudo nautilus" so I could delete it as root. So I deleted the folder but I did not get the space back!
I went to /.local/Shared/Trash and one of the folders I deleted was there but deleting it didn't get that space back either.
I did some searching but most of what I find doesn't help or tells me to look in the folder /.local/Shared/Trash folder but that didn't help any.
I can SSH to my own box using "ssh -X arancaytar@localhost" and run graphical applications. When I try the same using "ssh -X chris@localhost", I get an error message saying
Code: chris@enki:~$ gedit X11 connection rejected because of wrong authentication.
my /dev/sdb was a truecrypt partition that was mounted when I accidentally deleted the partition in gparted (instead of sdc, stupid). I'm pretty sure I haven't overwritten anything since then, but I'm not sure how to go about recovering this one. To confound the problem, the only way I can install stuff to my ubunut machine is by downloading on a windows machine and transferring by memory stick.
I was working on creating a partition on a new hard drive I was planning on using for storage. I wasn't paying attention and chose to delete the partition on my master. I am running a dual boot with Vista and Ubuntu. When I rebooted It will only go to the Grub> prompt. Ive ran TestDisk and though that I had corrected the problem but it didnt. After running TestDisk again here is what It came up with.
Disk /dev/sda - 320 GB / 298 GiB - CHS 38914 255 63 Partition Start End Size in sectors L HPFS - NTFS 0 32 33 28554 254 63 458734027 L Linux 28555 1 1 38585 254 63 161147952 L Linux Swap 38586 1 1 38912 254 63 5253192 Structure: Ok. Use Up/Down Arrow keys to select partition. Use Left/Right Arrow keys to CHANGE partition characteristics: code....
After writing the table above I rebooted. Windows prompted me for my restore disk. I rebooted to the live cd again and ran Fdisk.
To manage it more easy, I tied 2 harddisk in LVM. And I made an logical volume. It used ext4 for it's filesystem.
Today, I wanted to format and reinstall the system. So I booted the system using Ubuntu CD. But managing the partition, I accidently delete the logical volume. Because backup(/etc/lvm) was in itself, I couldn't restore the old config. I just create new logical volume.
As I expected, I couldn't mount it correctly. Mount said that "Mount: Mouting failed A on B! Invalid argument!"
I must recover it, because it has a lot of import data. What should I do?
I have a Laptop where I installed both Fedora 11 and windows 7 dual boot.
While I was upgrading Fedora 11 to Fedora 14 using preupgrade, I tried to edit /boot/grub/menu.lst file to make an option to continue upgrading the system after rebooting.
Accidentally, I deleted the file content and I couldn't restore it
I knew then that I'll face a problem when I reboot the system, and I faced it >> the grub selection menu disappeared , and only the line (grub> ) appeared when I reboot the system.
1- These commands:
Code:
But when I rebooted , nothing changed and the same (grub> ) appeared again.
2- I used the instructions in the PDF attached, but unfortunately nothing changed.
I think that I have to rewrite the menu.lst and grub.cnf files but I'm not expert and I don't know exactly what was there (locations , commands , etc. )
The current system monitor for the file system is shown in the next image:
I tried to install Ubuntu next to XP. After restart - no XP and no Ubuntu. Something wrong with loader I guess, I see command line prompt (of the loader I guess).
So I restarted from liveCD. But no "Repair Install" option like in XP CD. So, I deleted partition to install again on top of old, then learned a loader possibly could be fixed.
So, the problem is: testdisk cannot restore partition I deleted. I didn't write on disk anything. May be swap space after couple reloads from liveCD corrupted it?
It complains "The harddisk (...) seems to small!", it sees some other partitions and doesn't see what Gparted and Disk Utility.
Let me know the best approach to get back XP running (having Ubuntu would be good too).
Here below are the screen captures for details.
Quich Search results. Can't recover what's found. Why 4 partitions are found? Notice, "The harddisk seems too small !" Could this be a problem? HDD is not Maxtor anymore
The gap is there but no deleted partition shown
Essentially same thing... going for deeper search
Deep Search hasn't recover anything new. And shows same results as Quick Search (2nd testdisc image )Hit "continue"...
Now the partitions shown as deleted because of overlapping. The partition to be recovered is still not in the list.
Anyway, my final goal is to get WinXP back and if possible, install Ubuntu. It's nice that installer still sees the XP. Too bad the loader doesn't. how to get it done.
Unlike during installation of XP, ubuntu doesn't offer to utilize the deleted partition. Is it going to stay empty/unallocated? Forget the empty space, will I get XP running if I continue and install?
The top right panel item contains the shutdown, time, network icons, etc. I don't use the messaging icon so right-clicked and chose 'remove from panel'. The whole lot disappeared! How can I restore things to their original state?
I accidentally deleted the file called "fstab,v" not "fstab" The files location was /etc/fstab,v if it is very important file and what its used for & how to restore?, as my server seems to be running fine, but I don't want to get into any problems later down the line.
