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.
I am using mint 8 for a 2 weeks, I am noob to linux but I like Mint than any other linux distro which is great alternative to windows. I have a problem regarding password reseting.
1. My laptop automatically get logged in without asking user name and password.
2. I tried to change password for newly created user and root user using graphical way but it does not work.
2. I can perform administrator task using only OEM user which is default inbuilt user of mint.
How can make my laptop to ask password when mint get booted? How to change password for other users?
I am running Fedora 12 as Guest OS in VMware Player. I installed Fedora 12 by using a Prepackage VM . The root user name and p/w was supplied by the person who made this appliance. Is there way for me to change root user name and pw
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 just tried ubuntu 9.10 in recovery mode i came to know that i can change root passwd without knowing the password then i can change password of every user by logging in as root
hello i am trying to change my password, but when i type in the new password i get this:"The password is longer than 8 characters. On some systems, this can cause problems. You can truncate the password to 8 characters, or leave it as it is."my question is what kind of problem could i get and how can i change so i have to log in every time i start the computer?
I no longer have access to my root desktop. On a session I attempted to change the root username but i apparently assigned it a wrong directory that does not exist. When I rebooted with my new root username, i was instead recognised as a simple user (no root privileges). I tried the console to change to "old" root but root password is not accepted and there is no way to access to sudoer files. it seems that inserting a new username requires root privileges and i am back to square one. Simply logging with old root username and password after restart gives me a blank screen with nothing on it and cannot even reboot.
i used opensuse 11.1 ...there is option for root user to create password for root...but for ubuntu i did not find anything like that...so how can i create root password....or how can i use root
A friend of mine has told me to set a root password and use root (f.e. switching to su in terminal and work with root rights instead).Is there any way to unset the root password? I know how to use sudo now.
I want to add 50 new users, not on the server yet I want to add them all to group Accounting - with 1 option, not user by user I want to setup a default password for them all, and have it say something like 'You must now change password or no access will be permitted' Any other options I also want to do once, not for each user?
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.
Iam unable to chang th root password in ubuntu. after sudoing,passwd it asks for the old password, thn th new password twice, but does not change it. What do i do?
I'm on Squeeze with KDE 4.4.5. Basically, I can use my password for things like logging in, or authenticating on a shell with sudo successfully. But in other cases, I am asked to "become root", and when I enter my usual password, I'm told to check if I entered my password correctly. This happens with Aptitude (terminal GUI), for example: from Actions, I try to update the package list, and when I enter my password, I can read su: Authentication failure. However, if I start Aptitude by typing kdesudo aptitude on Konsole I can enter my password in the authentication box successfully, and use Aptitude with administrative privileges.
The example is valid also for other applications, such as System Monitor: just for the sake of the example, if I try to stop a process owned by root, say Aptitude, I'm asked for a password to become root, but my password doesn't do the trick. I'll have to open it from terminal with kdesudo ksysguard, then I'll be allowed to kill that process. Does it have anything to do with my choice at installation? I think I must have chosen to leave the root password field blank, and only entered my password as a user, for it explained I could become root anytime if there was need to with sudo.
I want to use root password instead of adding my user to the list of sudoers,In Arch wiki ander Root password:Users can configure sudo to ask for the root password instead of the user password by adding "rootpw" to the Defaults line in /etc/sudoers: but that did not work for me. it asks for root password.Why do I want to do that: 1. I want to do that, I like sudo more than su -c 'some_command'. 2. sudo enables bash completion, su -c does not. 3. I don't want to add my user to sudoers list.
I found many users Suggesting alternatives and lowering the important of my need for this, when I asked this question in anther please.
I want to run zypper without being asked for the root password. So I added the commands to the sudoers file:
Code: # User alias specification User_Alias ADMIN = XXXX #note: this is not real username. # User privilege specification root ALL = (ALL) ALL ADMIN ALL = NOPASSWD:/usr/sbin/vpnc ,/usr/sbin/vpnc-disconnect ,/usr/bin/zypper ref ,/usr/bin/zypper up
But I'm still being asked for password. I should note the the vpnc commmand is working as expected.
Is this a Fault on my part or a bug?? (not sure if this is the right place for this let me no if not i'll move it I want to add a user to Group "freevo" but if i open User settings via the GUI menus and click on the keys button to enter the root password it keeps coming back to me saying that the password is wrong even though it is'nt (and cap's is off).
So i try the terminal "user-admin" and had the same problem wrong password So i try'd "sudo user-admin" and entered the password at the command line and up pops the User settings GUI with root privileges
Stumped on this one. I'm trying to set up limited sudo authority on a desktop with some sensitive user data, and as an extra precaution I wanted to configure sudo to use a password other than the user's or the root's. I'm not sure how to do this. From the manual, we have a few options, such as "runaspw" or "targetpw", but none seem quite what I'm looking for.For instance, "runaspw" could be used if I created a user for nothing other than sudo(ing) purposes, but it requires you set "runas_default", which means that said user would have to have authority to execute said commands in the first place. This is workable, but seems like a lot of extra configuration for each specific command that I want to run, as well as creating some issues with simply commands such as "shutdown" or "reboot". Also, "targetpw" can be used in conjunction with a sudo(ing)-only user if I set an alias, but, again, this isn't quite what I am looking for.
Ultimately, what I am really concerned about in this situation are keystroke loggers, so I would prefer to avoid repeated entering the user or root password when performing administrative tasks. Also, I would prefer not having to create a sudo(ing)-only user as mentioned above to prevent a comprimised password resulting in an attacker being able to log into my system.
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?
I m Trying to get vsftpd usergroups to work i accidentally moved a file called passwd from /etc/vsftpd/ to /etc/, resulting in my root access is destroyed! how to restore the passwd file so i can keep working, or do i have to re-install the entire box?
I want to do setting in RHEL5 such that user should able to change his password only once in a day.I have changed the fourth field (i.e. minimum number of days to change) in in "/etc/shadow" file for "root" to "1". But its not working. I am able to change the password of "root" using "passwd" command.Any one can help me out on this issue
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. I am getting a root prompt but for some weird reason the root commands are not found. When I type passwd, I get, "command not found". Moreover, If I try reboot and shutdown -h now, both fail.
