Debian Installation :: Unable To Login As Specific User - Machine Not Accepting Root Password
Jul 31, 2014
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?
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.
My application is installed on root of RH enterprise 5 and is run via user on the same machine. This need ssh without password from the user.
i do the following : 1. run ssh-keygen in .ssh directory of the user. 2. copy the id_rsa.pub as the authorized-keys in the root's .ssh directory 3 chmod 600 to the authorized_keys 4.restart the machine 5. login from the user and ssh SER ( SER is the entry in the /etc/hosts with the ip address of the machine) 6 It still prompt for the password
How can i ssh from the user to the machine without password.
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?
not able to Login as a root in my fedora 11 machine , but I can login with other user.when I login with as a root user the error occurred "user authentication failed ". After login with user account when I open Terminal and try to login with same username = root and Password= admin then I can login .
I recently installed vsftpd on my server. I noticed that users on the machine can login into vsftpd with their username and password on the machine and go to their root dir "/home/username".Now, I want to give some people a vsftpd username and password so they can upload and download files and folders to their folder, but this folder has to be in the "/var/www/(username)" folder. I don't want them to be able to go to any other folder than their own folder like "/var", "/etc" or "/home" etc. Also I don't want them to be able to login on the machine as a user, through putty for example. They should only be allowed to acces their folder with vsftpd, nothing else.
I'm creating a bash script to do some tasks for me. I would like the script to be run at a set time of everyday. My first question is if it is possible that if one of the commands in the script requires sudo, is there a way to get around it with out making sudo not require a password. Such as, is there a way to include the password in the script? If that is the case, I can always just set the file as read only by sudo. I've been looking for a way to do this, with no success. if I have a command that wants input, how do I give it to the program. For example, if I want to make a zip file that is encrypted, the command would go as:
Code:
zip -r example * -e
now how would I get the script to insert my wanted password.
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...
After upgrading FEdora 13, user ravi was added. Then after few days neel was added. Both of the users were already existing. So when attempting login to neel, we found that every file is owned by ravi. So we did$chown -R neel:neel But after that problem started and when we rebooted the machin, there were no list of users on login screen. (then I connected to that comp remotely, it worked, but somehow I was not able to switch to root) It says incorrect password (though I new it very well). So I went to maintenance mode and changed the root password, and rebooted. Still problem persists.Now I am not able to login as root (from anywhere, login screen , terminal, remote)No list of usernames on login screen ( but i can choose, other and type login-password)
I have just upgraded my laptop from F8 to F10, and I am unable to login to the system as root user.At login, it provides 2 options, one is the user I created and another called 'other'.On selecting 'other' and providing uid/passwd as 'root/<rootpassword>, it says "Unable to Authenticate User"!!However, when I tried to access my windows partition, it happily accepted the root password
here is Maneesh Kumar Dhiman from india persuing B.Tech in computer science and Engg. i am using ubuntu 9.04 and i have the problem with it that i cannot being able to update it by following ways:
1. by using snaptic package manager
2.by using update manager
3.by terminal commands and also i have a problem with U9.04 n that is i can not being able to login from user screen as a root.
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 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 upgraded a Guruplug Display machine running Lenny to Squeeze. It's running Linux on a MicroSD device, running an ARM-cpu.

However, after rebooting, every non root user was unable to access anything related to the net.This means, DHCP failed to auto start, ntp is giving errors, etc

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've installed F12 twice now. After completing the installation and getting all the updates via YumEx, my network trouble begin after a reboot. I am not able to login as root under gnome so I can't see the services panel.
Tried to reinstall 'NetworkManager' after the fact but of course I have no network connections so I may have made the problem worse. I hate to reinstall and repeat the same troubles over again as it consumes a lot of time. I don't know where to begin.
I downloaded Gentoo and burnt it on CD.I did boot the livecd and the system passed starting stage and it recognised my hardware. After that, there islivecd login prompt, and obviously I tried to use root and no password but it says login incorrect. This is what I did:
Code: livecd login: root Password: [hit enter here]
