Fedora :: Boot To Grub And Recovery Root Password

Jul 29, 2009

I am new to Fedora. I know my top probably already been posted somewhere but I just could not find it. I just installed Fedora 11. But my root password does not work (I guess was my fault to type wrong in the first place or some type of short term memory lost). I looked at the root password recovery procedure which involves select single user at GRUB page when booting. But for some reasons, Fedora 11 does not boot into GRUB. I tried Alt+CTRL+F1, F1 or Shift, none of those gives me Grub screen.

Red Hat :: Cannot Change Root Password (let Alone Standard User's Password)?

Jan 6, 2009

At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.

CentOS 5 :: Recover / Reset Password For Root Via Single User Mode

Oct 20, 2009

Can someone assist me with recovering/resetting the password for Root via Single User Mode in CentOS v5? I've modified the kernel line using Single, S, and 1 but it appears that these commands are being totally ignored as the server continues with the boot process and displays the GUI logon screen. The server in question is a VM box running on ESX v3.5 U4. The person that created this VM is no longer employed here and I've exhausted everything I know regarding Single User Mode.

General :: No Prompt For Root Password After Attempting To Enter Single User Mode?

Jul 13, 2011

I followed instructions to enter single user mode by adding single at the end of kernel line but after that it doesn't ask for root password but brings up the sh# prompt. Isn't that supposed to be insecure? I understand for this the grub password can be applied but even after adding "single" it should ask for root password..or it should not..??

General :: CentOS / Sudo Doesn't Accept Root Password But Logging In As Root Works

Apr 9, 2010

I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?

Ubuntu Installation :: 10.04 - GNU Grub Version (Recovery Mode)

Feb 26, 2011

I am trying to install ubuntu 10.04. I had ubuntu 10.10 but I want to install 10.04 (32 bit) because 10.10 is slow. Problems with cd drive/cd caused installation to be incomplete so system cannot reboot at all.

I just tried the "Try Ubuntu without installing" option and got
Gnu Grub Version 1.98+20100804-5ubuntu3
Ubuntu, with Linux 2.6.35-25-generic
Ubuntu, with Linux 2.6.35-25-generic (recovery mode)
Ubuntu, with Linux 2.6.35-24-generic
Ubuntu, with Linux 2.6.35-24-generic (recovery mode)
Ubuntu, with Linux 2.6.35-22-generic
Ubuntu, with Linux 2.6.35-22-generic (recovery mode)
Memory test (memtest86+)
Memory test (memtes86+, serial console 115200)

Which should I select? and what do I do to go on to install/reinstall 10.04?

Ubuntu :: Can't Get Grub Recovery Mode Menu To Boot Up

Apr 30, 2011

I started a thread over in installations and upgrades in which I was trying to upgrade from Ubuntu 10.04 to 10.10 using the upgrade manager. My computer froze in the middle of the process, requiring me to restart my computer. When I try rebooting Ubuntu, I get an error message "The configuration defaults for Gnome power manager have not been installed correctly" and then a blank screen. No mouse pointer, no cursor. It will not take me to the Ubuntu desktop screen. I've already found the sudo commands I can run to try and fix Ubuntu. They are as follows:

sudo apt-get clean (If the problem is not having enough free hard drive space)
sudo dpkg --configure -a (If the problem deals with the upgrade installation process)

However, what I can't get is the terminal to come up to run these commands. In the other thread I started, someone mentioned that in the Grub menu, you can choose "recovery mode", hit "enter" to boot it, and it will give you a menu of options to choose from. However, when I choose "recovery mode" and hit "enter", I do not get a menu but instead 3 pages of data about my computer that ends with this:

"Begin: Running/scripts/init-bottom...
Done. "

It gives me a blinking cursor at the very end but I cannot type anything and I cannot page up to see the 3 pages of data. What I am looking for is a way to get to the recovery mode menu OR somehow open up a terminal so I can run the sudo commands. My computer automatically logs me in, so I do not get a login screen and Ctrl+Alt+F1 does not work for me. Anyone know how I can open a terminal with only access to the Grub menu? Perhaps a BASH command that I can use in the command line that will open up a terminal? To summarize: My computer does not boot Ubuntu. I get an error message followed by a blank screen. It does not go into the desktop screen so I cannot choose Applications->Accessories->Terminal.

My Grub menu consists of Ubuntu and it's version, Ubuntu and it's version with recovery mode, memtest, and Windows XP (I have a dual boot system). In the Grub menu, I can select "e" for edit, "c" for command line and "enter" to boot either regular Ubuntu OS or Ubuntu recovery mode. "Sudo" commands are not recognize if I choose the command line for either Ubuntu OS or recovery mode. I have a Live CD for 10.04 but you cannot run sudo commands because you do not have access to root on the Live CD.

General :: Avoid Logging With Root User?

Jul 22, 2010

I have created a linux machine and installed some softwares on it with root user privileges . I used to login with root user credentials for doing the various task.

Later i have realise that this is not the best practice to follow and there should be a new user with less privileges to be created for doing the day to day task.

I have read the steps to create the user but will that new user sufficient enough to do the task that i m doing it through root user?
Will my software allow the new user to work on them?
I would be glad if someone points me to a guidelines on what should be my next step?
