Debian Installation :: User Password Rejected And Have To Login As Root
Oct 28, 2014
Suddenly Debian started rejecting my user pw and I have to login as root. Perhaps this is a coincidence, but this started when I re-booted after adding Russian keyboard layout in etc/default/keyboard. The Russian keyboard added successfully.
Being logged in as root, renewed the pw of my user account (actually assigned the same as wes previously), got confirmation the the pw has been changed. Reloaded. Yet it keeps complaining that the pw is wrong.
Having installed Debian 7 on an old machine from a Liinux Format Magazine DVD I was unable to log in as a specific user. I can login as root and use useradd etc but when I logout of root I still cannot login as a user and nor will the machine accept my root password. I have to shutdown and reboot to get back into root. I'm using O'Reilly's Linux Pocket Guide from 2004 for the commands. Could it be that things have changed?
I installed Jessie with Cinnamon alongside Win 7 - all went quite well though I did have to do a bit of guessing along the way.
Following online tutorials etc, I tried to install sudo from the terminal. It did not go well - some stuff appeared that was not shown in the instructions from many sites. So I abandoned it, or so I thought.
Then I discovered that my root password was no longer recognised. So I reset it, following online instructions.
This was successful apparently, as I can log in as root and see this in the terminal.
But on trying to start Synaptic ( and later others), I found that the new root password would is not authenticated, but my user password does authenticate successfully. This seems to be the wrong way round!
Debian 8/Cinnamon fresh install. /home is being shared with two other OS's, Mint and openSUSE. At the login screen I enter my user name and password and the screen blacks for 1-2 seconds and comes back asking for user name and password. I can login as root. As root I can launch the Group & Users GUI and attempt to set the user's password, and pressing the 'change' button does nothing obvious.
I can set the user's password in a terminal, which reports success. I tried to switch users and login with the changed password and I get the same failure. If I try to login with the original password I get an incorrect password error, suggesting that the password is being processed properly and the problem is elsewhere.
On previous installs with Mate and the default desktop (Gnome) I didn't have this problem. So, the questions are: Is it Cinnamon? Is it an unlucky chance bad install? Config files are typically in /home, which is being shared with Mate and KDE, is this the problem?
I edited fstab to automatically mount my windows data partition on boot, but I screwed it up by not specifying the file system type, however that is not the problem, I was able to fix that easily. The problem was that when it failed to mount the partition, Debian automatically entered root and I guess that is to be expected in order for me to fix it, but I never configured a root password and it just gave me full root access without asking any password, not even my user password. I though that was strange so I set the root password and sure thing it asked me for the root password this time without automatically logging into root....
I then tried to lock the root account to see if it will ask me for a password or not, it did but of course I wasn't able to login as root because it was locked now and I was left with no way to access the system. I had to fix fstab from a live cd so that I can login normally as the user....
I didn't know what to search for or if that is the expected behavior if you don't set root password during installation, but it just seemed a bit strange to automatically enter root when you specifically disable root login during installation...
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'm using Debian Jessie Cinnamon right now. I've got 1 user account on my machine--fred--as well as root, of course. "fred" is an administrator, and many times that is enough for root priviledges, for example, I can install packages via apt or dpkg. However, I cannot access "Users and Groups", or install packages via GDebi, with my password. For that, I have to have the root password.
I know that it is possible to let the admin account handle everything and not even need root--for example, Mint and (I believe) Ubuntu do it this way. I don't know how, though.
Code: Select allgroups fred fred : fred cdrom floppy sudo audio dip video plugdev netdev lpadmin scanner bluetooth
I did disable the root account by Code: Select allsudo passwd -l root to see if it would make any change. Nothing different happened except that I now can't use GDebi or access "Users and Groups" since the root account and therefore password is inactivated. Not a big deal to get it back, though.
I have lost my password for my root and for my user account.
Code: Select alluser@debian:~$ su Password: su: Authentication failure user@debian:~$ su Password: su: Authentication failure user@debian:~$ su
I have just installed a gust debian 8 on debian 8 host in virtualbox, and when i wonted too login as su/root on the host there where no login possible, is there a way to regain the root password for the host?
Since upgrading my Debian/unstable amd64 installation a few days back I can no longer log in as either root or user, whether to SDDM, via the console, or via ssh. When trying with the console, I can see the login message flash briefly on the screen, before the console resets itself.
I can boot into recovery mode, and examine log files. I enabled systemd debug logging and, amid reams of messages, these seem the most pertinent:
Sep 25 02:24:43 cooler systemd[1]: Received SIGCHLD from PID 937 (login). Sep 25 02:24:43 cooler systemd[1]: Child 937 (login) died (code=killed, status=6/ABRT)
I have installed Timeshift. Administrative password is requested when I click Timeshift icon in Gnome menu. I enter the password (or paste it to be sure) but it always returns with "incorrect password, please try agian" message. I am sure that I type my password correctly.
I looked at the icon's properties. It runs "timeshift-launcher". I changed it as "gksudo timeshift" or "sudo timeshift" or "gksu timeshift", enabled "Launch in terminal", disabled, but nothing changed. Always same password request window appears and it rejects my password.
However when I run "sudo timeshift" or "gksudo timeshift" command in Terminal it accepts my password and runs.
When I run for example Synaptics via Gnome Menu, password request window is with black background and it accepts my password. However when I run Timeshift, password request window is with gray background and it rejects.
Root password was not defined in my system during installation and I am the only user. I run administrative commands via sudo without any problem.
I am new to ubuntu and I've installed it but I didn't use it too much. Now I was trying to login into ubuntu but I forgot the root password. Can I login into ubuntu or change the root password. I didn't make any other user than the installation were asking me. If I try to reinstall the ubuntu, the setup will help me to choose the same partition (to overwrite on the previous ubuntu)?
When booting from the Ubuntu 11.04 CD, it asks for user name and password to install. I downloaded the iso twice and did a checksum. Do I need a user name and password before installing? What is the user name and password? I read the documentation and cannot find any entry about user name and password needed when booting fron CD.
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 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
i changed my password and whenever i log in i get a message that ur login keyring password and user password do not match, so how do i change my login keyring password!!
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?
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.
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.
when i login to openSUSE a window named login keyring appears and it asks me root password. it happens everytime when i login. how to fix this problem?
i am having problems with privileges i have created a new user with my name, but i cant get root privileges on it. i need the same privileges as the root profile.
i just installed linux mandriva 2009. i set password for root and created a user account. when i try to login as root, after logging out as user, it does not allow me and gives the error "root logins are not allowed". even it does not show the root account. if i try to go to root from konsole terminal using su root, it allows to enter as a root but when i try to start the GUI with startx it gives error.not sure what to do and why i can't see my account in GUI mode
I'm seeing really bad user login format under a standard installation and am wondering why ubuntu does this as default. I have noticed that the graphical login for gnome sizes itself to accommodate a user's exact password length. This indicates to me that somewhere on the unencrypted part of a standard installation with user encryption contains at least some indication of the content of the password length which seems a security flaw even if not a complete hole, it majorly reduces the number of attempts a cracker would have to cycle through.
And that's assuming that *only* the length is contained. Furthermore it seems that it would be MUCH better to simply display the number of characters entered into the pw field and allowing the gui to expand itself from an fixed size as the field is filled out so the the user still receives visual feedback for entering characters. Either a simple character count display should be entered into the field or a 10 dot to new line so that one can visually quickly count the number enter by multiplying from a 10base graphical observation.
I finally got Sueeze installed and it works great for my user account. It won't accept my root password and so I can not do anything as root. This is strickly a home desktop setup and I am the only user. I have a working Ubuntu 10.10 in the ajacent partition. How can I change (or reinstall) my root password. Everything I've found says to boot single user and I have, but I still need the root password in Debian.
How to enable Root login...i cant copy or move something on the HDD...I have administrator rights and password for root but i cant change permissions for the HDD without login on root and root login are not allowed .
I have tried to install the newer version of hplip on Debian 7.8 because the standard version does not support my printer.
So I proceeded the installation according to the instructions in hplipopensource.com, but the installation hangs after I enter the root password as this image: [URL] ....
