Fedora Installation :: Lost All Data On Drive By Bad Clicks - Change User To Root?
Jul 21, 2009
This is my 6th install of Fedora, begining with Fedora 4 I have had very good luck with all until 9 and I lost all data on drive by my bad clicks in a frustrated session. Now I have a great install of Fedora 10 with the exception that I fouled up and typed in a user (myself-'andybill') and am finding out that the work I need to do cannot be maximized by operating in user - andybill, I need to be super user. I have just moved and have not done any collaboration with our senior partner in a data development start up that he is the intellectual property in deed and law. For me to get back on track my using this OS I have to be master of all libraries, drivers etc. I am a nu-b (only 2 1/2 years, with no computer science background. This explains why I need step by step commands without abbriviated lingo-So if I can remove myself as andybill, make all root

I have Slackware 12.2 installed on my computer, as well as a Windows Xp. I have a hard drive named '/fat-d', which is formatted to be 'fat' and is normally used under XP. This drive can also be accessed under Slackware, both as root and the normal user.I can not write to the directory '/fat-d' when I am not root, it is normal since 'ls -l' shows that its owner is root and other users have no permission to write. The problem is that, when I tried (as root) to change the owner to the normal user:# chown [normal_user_name] /fat-dI got an error: chown: changing ownership of '/fat-d/':Operation not permittedBut how can the root have no permission to change the owner?

I have 3 drives in my computer. I installed Fedora 11 on my two biggest one, with the LVM treating them as one single drive. I attempted to install XP on my last drive. As I was installing, I selected my third drive (I'm 100% sure it is the correct drive as it is an 80gb whilst the others are 120 and 200 respectively) and told it to delete the partition on that drive and format. After I did that, it started to format, starting with my 120! I'm fairly sure that it was merely a quick format, as it only took 5-10 seconds for it to format, and that my data is still there. Is there any way to recover my "lost" data, or did I just really screw myself over?

I didn't realize my system drive had filled up... and TaskWarrior overwrote my 'pending.data' with a 0-byte copy. d-: I had worked SO hard to get all my tasks imported from various other notes (many of which I deleted along the way), and hadn't yet prepared for the possibility of data loss. Should've set it up to use my Dropbox...why doesn't TaskWarrior make ANY backup buy default? That data is so important, and yet so small and trivial to backup. Anyway, my 'undo.data' is totally intact and seems to contain all the information theoretically needed to reconstruct 'pending.data'. Unfortunately right now I have no sample 'pending.data' to look at. d-: OR: does anybody know of a simple Linux utility I can use to recover previous file versions? It's possible no data was overwritten, since the replacement is empty.

I have a windows 7 ultimate host machine, installed oracle virtual box on it. Made a iso image to boot fr fedora. All this is fine when the installation is complete, it asks for reboot. Reboot done. Then I went to terminal. Did a SU - root to get into the root. Then I did a firstboot command to enter information. I created a user for myself and at the end rebooted the virtual box.
When it starts up, it does not show my user. It just shows "Automatic Login" and it logs in as Live System User. Even if I try to switch user then it gave me a authentication failure when I enter the credentials of the user which I created. If I try to create users manually using system administration, the user is lost after reboot. I have tried all possible steps...as instructed on the net.

I just did a clean install of suse 11.2. I then installed acct, using yast2.Finally I did:sudo /sbin/chkconfig psacct onsudo /etc/init.d/psacct startSo far so good. The problem is that if I now do:sudo /usr/sbin/sa I only see root processes. None of the user processes seem to show up. If I run it with -m flag, I just see a total and a root row, no users show up at all. But I do have user accounts on the machine, and I am working in one of them (only root when necessary).Any ideas why, or what to do about it? Is there something else that has to be configured?As I understand it, sa -m should show a summary for all users, not just for root.I want to be able to see how much time different users are using.

I have Fedora Core 8 installed. I would like to reinstall it so as to get back commands that have been lost. To preserve my user data that has been stored in logical volumes, what selections should I make in the installation process? Are these selections essentially the same for Fedora Core 10?

I often put together complete computers from spare parts. When I do, I put Linux on them and put my name as the root user. However, I don't build these to keep them for myself.....I usually end up giving them away to someone who needs one and can't afford to buy one. What I would like to do before givi9ng them away is to change the root user name to their name. How can I do that? CAN I do that?

For a user on a Linux host, I need to make everything inaccessible besides his home directory. I have heard that this is usually done by changing the root directory for the user (and setting it to the user's home directory), however I couldn't find the way to do it.
I thought about the chroot command, but it seems it just runs the specified command, considering the specified directory as the root directory. So it seems chroot is not what i need. So my question is: what is the command which changes the user's root directory?

Having just installed fc13 and downloaded the KDE package I attempted to log out as user and back in as root, but I keep getting a message about the wrong password. This is odd as the same password works in terminal if I try to become a SuperUser. I have tried turning off SELinux to no avail. I cannot log in from cold as root,only as user.

I was sure by time that something wrong has happened and i did not switch off my monitor so that i can retain my application.I tried lot to increase teh /var so that i can update my yum and install some lost application but allin vain i tried Gparted which can only decrease the size .
I had 40 GB unallocated space so i tried to boot from Live Fedora 12 DVD and was able to see my all the files and filesystem.
All my data in /home was intact.I tried to go to grub and went to boot hte kernel and Initrd and was able to go to #root but again was not able to update the system as network was missing.The SYSTEM was Not booting and stuck in between.
Tried to change the /var to var1 copied /var content to /var1 and made changes in teh /etc/fstab still did not work ,so finally went to repair with Live cd but could not get "Linux rescue" anywhere not even to upgrade option so finally installed the New linux without touching / and /home partition rest were deleted and formatted for new instalation.Now i could not see my data in /home directory although i could see data in /root(old) and all ..i am now lost ..my data is nowhere ..please help me.I can only see /home(old) but it says empty and shows 6 GB unused and 3.3 GB used when seen in Gparted .

I was a regular Windows user and have installed Ubuntu 10.04 LTS 2 days back. Not really sure what was my mistake during installation but that had erased all my data. I lost windows completely and lost all my data in all 4 drives including drives itself.I searched in internet and forums as how could I recover my data, and got solution to use test disk. Testdisk worked perfectly, I recovered my 4 drives and retrieved data for 2 of my drives. But I still cann't retrive my important data from other drives.I guess data still exists in hard disk. (no free space , and no data)I know there could be several threads which had solved this kind of problem.

I booted with a knoppix cd and both drives are found and contain data. What steps can I take to remount these drives and recover the data?

I need to edit the system time as a not-root user. I am carrying out the following actions in my program.
1. Read the User Id of the process. User_ID= getuid()
2. Printing Capabilities(Permitted, Efffective, Inheritable)of the process
3. Setting UID = 0, using setuid(0)
4. Calling the prctl(), function to keep capabilities
5.Switching the UID from root to User_ID of the process
6. What we have now is a process with root capabilities as a non root user
7. On printing Permitted, Effective, Inheritable capabilities, I get the following
--> Permitted = 0xfffffeff = Effective
Inheritable = 0x0; with UID = 1001;
8. I then try and set the system time with --> system("date -s 10:00");
9. I get an error: date: cannot set date: Operation not permitted
10. I am unable to understand as to why I cannot set the time even thought the capability bit CAP_SYS_TIME in the Permitted and Effective sets are SET.

I got my livna, and rpm fusion repositories in order today, and my dvd started playing movies, but when I tried my cd rom, nothing happened when I inserted a music cd. I googled for info and came accross a blog talking about permissions. And when I right clicked on my cd drive icon and looked into permissios, it said: "The permissions of "CD DRIVE" could not be determined. The open with tab was blank, so I selected "Rythmbox" and thought that would fix it, but it's still not doing any thing after inserting cd. Also if I try looking up the cd from within Rythmbox, the cd doesn't show.

Have just upgraded (14-->15) using the dvd option; installed the nvidia driver (I think) and am able to startx and get to the Gnome 3 desktop (Wallpaper and top "task" bar look correct)..But, the mouse and keyboard have absolutely no affect. No matter what I click on, or what keyboard combination I use, nothing happens..(Have spent the last 3 hours researching it; and just seem to be getting nowhere.. I can do anything I need to from the CLI; but am not sure what to do..

Generally I am used to installations of dual boot on different partitions(the traditional method) any windows OS with any ubuntu OS.I tried that with backtrack 4 and Ubuntu 10.04 netbook edition! I had previously installed ubuntu 10.04 and then had an extra partition that had data in it.Went ahead to boot with the backtrack 4 disk BUT it did not give me an option for installing them side-by side so i did it manually by editing the partition with the partitioner! I had 2 swamp spaces one i which was initially there for Ubuntu and the other i created! Then simply formated ine partition with EXT3 and mountpoint of / which made two of them!after installation, the grub shows that there is another OS but when it does not load!

without realising I started thunderbird from a root window, I set it up along with rules and about 2 hours finetuning.
I figured out how to get the icon on the top panel, but that is naturally started as my user gsm.
Is there an easy way of migrating the whole mailbox and subfolders form the root install to the gsm user?
Or is it easier to start from scratch?
