Red Hat :: Change Root Password With The Passwd Command?
Jan 15, 2010
I have Red Hat version 4 I was trying to change the root password with the passwd command.I get the error passwd: PAM [dlerror: /lib64/security/sufficient: cannot open shared object file: No such file or directory] I have change the password before.
Like the title says, I'm unable to change root's password.
I boot into singleuser mode, run passwd, get the
Code:
Boot into multiuser mode and I'm still unable to login.
Two questions: 1) Anyone have a 'default' /etc/pam.d/system-auth that I can replace with the system-auth that was obliterated by the pam_passwdqc update?
1. I tried to change my password by typing "passwd" in the terminal. It then asked me to input the Unix password. After I typed in the Unix password, it read "Authentication token manipulation error". Why did that happen? I know what the Unix password is.2. . What is the difference between Unix password and Root password?
I'm really new to Linux so this will probably sound like a pretty naive question to most users, but how do you change the root password?To install Java, I have to type # su into Terminal,which then asks for the password.What's weird is that when I start typing a password, no characters show up. I don't know if this is supposed to happen or not.I've found a bunch of different sites on the Internet that explain how to change the root password, but none of them seem to work for my specific work station.
I've got Ubuntu 9.10 64 bit. In the GRUB boot menu, I can choose to boot normal or in recovery mode (I'm led to believe older versions don't have this option).I've tried typing # sudo passwrd into Terminal, but I already have a root password set up apparently, so I can't change it there.
I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?
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.
I edited the passwd file to modify the default shell for root from bash to tcshnow when I try to login to root it gives me the following error:"su: /bin/tcsh : No such file or directory"
For some reason passwd does not accept my current password as the old password when i try to change my password with the command passwd. Im not sure whats wrong with whatever linux uses to handle passwords but I cant even change passwords with the root user account. Is there any way to fix both of these problems.
I got during my last year of high school, and I recently installed Fedora 11. During the installation, I misunderstood one of the questions, and set my root password as what I wanted my account password. I want to go in and change it, because it's pretty easy to figure out and has me feeling really vulnerable, but it won't let me. I went to System-Administration-Root Password, entered my password, and put in a new one, but it won't let me click Change Root Password. The button is faded out and unclickable. I've tried several different passwords, and triple-checked each to make sure I typed it in correctly, but it won't work.

I am trying to reset the root password of Squeeze so that I may be able to update. I forgot it. I have followed the howto Reset Root Password without success.

Forgot root password on fedora 10. Reboot into runlevel one and changed passwd and it said all tolkens updated. Typed exit and it didn't reboot and at login screen I logged in as other "root" and it didn't work with new password. So I redid the runlevel 1 and password change and typed init 6. It didn't work after that also. How to change fedora 10 root password if the old password is forgot?

I recently decided to give linux a try on my personal machine. I work on a unix machine from time to time at work but am pretty much a novice with what I am doing on this laptop. I am running Ubuntu 9.10, I was trying to change the root password on my laptop but ran into the following:
charles@charles-laptop:~$ whoami charles charles@charles-laptop:~$ sudo password root
I think I would now and then like to change my Ubuntu root password for my own peace of mind. Is there a way to do that without having to re-install the os?

Someone hacked my CentOS 5.4 test box, that I run at home with a gnome interface. It is connected to a domain name, the hacker changed only the root password. How can I change the root password? I get a graphical Grub at startup and if I press "e" nothing happens. Is there a different way to have Grub boot in text mode? Remember that I don't have root access. I was thinking to use the linux rescue mode, but I don't know what steps/commands to enter.
I've been using Ubuntu for like a year now. Whenever I want root privileges I just type sudo and enter my User password. I wanna know if there's a way to change this, in a way that My User password is: "ABC" and the password needed to have root privileges is: "ABC123". I have no problem using the terminal, I actually prefer it to any GUI, it just seems easier to me.
To comply with standards I need to change the root pw every so often. However, I really don't have a need to know the root password; as the only thing using root, is for ssh authenticating via ssh keys. What I want to do is automate the root password change monthly via a cron job, to a random value. Is there a way to do this without knowing the previous password?
How can I change the root password of MYSQL server. I have just finished installation, but I mistakenly typed the wrong root password, and now I need to change it from command line, because I cannot even access the UI.
I don't know that this post fits here, nor does it fit in "Applications." installing suse doesn't seem to give you the chance to name your computer. Now my computer is called "linux-0qvi" or something strange like that. I want to name my computer. Can I do this now without screwing things up??
Also, during install, there didn't seem to be an opportunity to make a separate root password. My first (and main user) account is now set up with admin rights, so I have to type in my account password every time I do something as root. Can I set a separate dedicated root password without screwing up my system?
I have pc/os linux 2009 installed and I recently got the following message while trying to boot up my system:
*checking root file system...fsck 1.41.4 (27-Jan-2009) dev/sda1 contains a file system with errors, check forced. /dev/sda1:Inodes that were part of a corrupted orphan linked list found. /dev/sda1:Unexpected inconsistency;run fsck manually. (i.e., without -a or -p options) fsck died with exit status 4
*An automatic file system check (fsck) of the root filesystem failed. A manual fsck must be performed, then the system restarted. The fsck should be performed in maintenance mode with the root filesystem mounted in read-only mode.
*The root filesystem is currently mounted in read-only mode. A maintenance shell will now be started. after performing system maintenance press Control-D to terminate the maintenance shell and restart the system.
Give root password for maintenance:
The problem is, when I enter my password I get an incorrect password prompt. How can I change my password so that a manual fsck can start? Why did this message error message appear in the first place?
I have a Suse 11.0 Server that has been running for a long time and I have not had to touch it, well I need to get into it today and I forgot the password.
