Ubuntu :: Authentication Failed Message At Login Page
Mar 20, 2010
the laptop of my friend runs ubuntu through wubi. The system suddenly freezed and she restarted it manually. After doing a check disk and automatically repaired some packages(unfortunately she doesn't remember what exactly, only just inode information appeared), she can't log in as when she types her username and password the answer is authentication failed. We tried to change the password through recovery mode but nothing happened.
1. Do you have something to propose to solve the login problem?
2. If not how can i access and back up her ubuntu documents through windows?
My Redhat 5.3 desktop running on an AMD 64 system was not receiving the updates from rhn until a few days ago when it started checking in and downloading updates. The updates crashed generating bug reports. I tried running yum-complete-transaction command, it aborted also. I found a knowledge base article with instructions on how to rebuild the rpm database which I followed. After completing the procedure I tried to reboot. The system gets to the logon screen and then I get the message Authentication Failed and the system locks up. The commands I ran are:
rm /var/lib/rpm/__db* rpm -rebuilddb yum clean all
I am also seeing a message during boot up that the module libxml2 is missing and when I try to download the package from rhn yum cannot find the server.
Earlier today I was setting up ssh on a new computer. I modified permissions on the Passwd folder to complete the setup. I few hours later when I went to sudo something in the terminal I received the notice of an incorrect password (after using sudo prior to this), even though it was typed correctly.
I tried to restart the computer to solve the issue, but was met with an Authentication Failed message, regardless of the user I tried to log in with. I was hoping I could log in with recovery mode but was unable to do that as well. I have searched a substantial amount and have not found a solution. Could this be an issue with permissions on either the Passwd or Shadow folder? If so, could these be changed if I ran a Live CD?
Now i will try to explain my problem.I just installed fresh 11.04 openSuSe 64bit.After doing all the configuration I rebooted and tried to login.Nothing happened.Googled some things, tried ctrl alt f1 and login as root, also tried to login as root, even changed my root password to be sure.Still, nothing happens, except for the thing that everytime I try to login as root it says authentication failed, but if i type my password bad it says bad password.
when I get into the login page, I can only see the background and the login box in the middle of the page just turns whole white and keeps flashing. no response for any clicks. I was force to ctrl+alt+F1 to switch to init 1 to do my work. But I still want to use my graphical desktop either KDE or Gnome is ok. I am using gnome.
I've been using Ubuntu since 6.04, not a linux guru by any means but can usually get myself out of trouble.
So, the issue... I installed 8.04 on my mother's laptop some time back as she was having trouble keeping Win 2000 running (she has a low spec no-name generic laptop btw). I live in Autsralia and she in England, i thought i could better support her if she was running Ubuntu... All has been well with 8.04 but with the new LTS release (10.04) i thought i'd talk her through the upgrade... Did the online upgrade via Update Manager, all seemed to go OK but when she went to log on after restart she got an error saying 'authentication failed' even though we are 100% sure we have the user name and password correct... Tried to do a ctrl+alt+F1 to by pass the GUI log on but couldn't get the terminal session to open up, just got a black screen - no command prompt.
So... thought OK re-install... downloaded the ISO, burned and sent her a CD in the post... talked her through the re-install, all seemed to go well (again) - BUT, after restart, couldn't log in "authentication failed" again...
So, remember i'm trying to talk a novice through all this... any thoughts!?!
If i can get her to log in i can then support her via some kind of remote sesion or other screen share... and it wont cost me a small fortune in international calls!!! But if i can't get a log in, i'm dead in the water!?
I installed lighttpd to be able to view cgi files that display the status of my UPS. For the most part is has worked w/o incident i.e. until recently when the UPS battery failed on my APC backups xs 1500 lcd. I could not view the multimon.cgi file via the localhost or 127.0.0.1 url e.g.: [URL]... I'd get 404 page not found message. After checking links here and on the web, I tried: [URL]... The page is displayed. From this discovery, I'm not sure that this is a web server configuration or a network host configuration issue or what. I'm running Lucid with all updates, no mods to lighttpd except I added the mod_fastcgi line to the lighttpd.conf file
I have been used NX client on windows 7 connected to ubuntu with NX client/node/server with no issues. The matter started when I have formatted Ubuntu and reinstalled NX, from that NX connects but shows a key error as follows:
NX> 203 NXSSH running with pid: 4328 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files
I just finished following the instructions found here to install FreeNX on my ubuntu 10.04 server. It went smoothly, just used the default keys.Once I had that all set up I scrolled down and followed the instructions to set up the client and that went fine as well.My problem is with actually using the program.When I try to log in I get the error "Authentication failed for user tony" (my username). Do I need to change anything in the configuration other than setting it to use gnome and putting in the host address?oes it make a difference that my ssh settings only allow rsa login? I logged into the server with ssh to see if that helped but it did not. I even tried using the ssh key with the FreeNX Client but that did not work
I apologize first because I do not know if this is the right section for my problem, but I could not find anything more suitable. I have an Asus 900 with Ubuntu Netbook Remix 10:04 In a nutshell: I realized today, trying to install a new program with Ubuntu Software Center, that I can not anymore authenticate myself as root. Of course I have not changed the password, but the old one is not anymore accepted ("Authentication failed").
The interesting thing is that I can install programs without problems (using the same old password) with the package manager in Administrative Tools (synaptic). Here, the authentication works well. Opening a terminal, I can use sudo to run any command by providing my password, with no problem at all. Following some guides found on the web, I reset the root password (supplying the same one as before) and everything went well. Only .... nothing has changed! Ubuntu center software authentication always fails.
What could have happened? Maybe I did some mistake by editing /etc/sudoers to solve another problem some days ago. Ubuntu told me that my username was not in the sudoers file, so I resolved it by adding to /etc/sudoers the line myusername ALL = (ALL) ALL
I checked the contents of the file and, apart from this line added, it is as it was before (I compared with that on another PC with Ubuntu). Can anyone make some sense out of it? Starting from the fact that the package manager does function ... but software center does not.
I want to use nomachine, instead of freenx, and well it isn't working. SSH server works and all, because freenx works., same for neatx. But I hear with nomachine you can see the main display of the computer? Is this true? Well one way to find out, but whenever I try to login I get: Authentication failed for user x. I don't know why, neatx and freenx worked, even x2go, but not this.
Something happened with my Ubuntu installation - when it reaches to the "login" "password" screen it gives the message in the upper corner that the power management has not been installed properly. So, when I try to login, it throws me back to the login screen. This happens with every prevous installation available from GRUB menu: "! Install Problem.The configuration defaults for GNOME Power Manager have not been installed correctly. Please contact administrator."
The Recovery mode seems to work perfectly well, however it puts me in a dos prompt screen, from which I do not know how to operate.I believe one possible reason for this to happen is that my Hard Disk where Ubuntu is installed, altogether with the SWAP disc which ubuntu uses, are completely full. I tried to free some space through my installation of Vista, but the program Ext2fsd does not enable me to see the content on my ext3 drives, only shows first level directory structure (the foldrs appear "empty" under Vista.
Could someone help me with a "magical" command line that I can type in recovery mode please...so that I free some space from my /user/videos directory (I dont mind it wiped out completely) and also all "wine" installations, that I can also wipe out. If the reason of Ubuntu not continuing beyond login screen is space, I do not mind anything that can free some space somehow and enable it to start.
I have just installed Fedora 15 on my laptop, Now i am trying to install some programs like .... skype, drivers to my printer etc but i get this message: Failed to obtain authentication.... when the installer is trying to solve dependensies...
I have tried to log in as su but i cant that ether due to fail password or username... that is the message i get at the log inn screen.
I just tried to updated my UBUNTU 10.04 to 10.10.I missed the page where I was asked to reuse the current GRUB information.The system hung after trying to load the new GRUB.I rebooted, and got an error about Configuration defaults for gnome power configuration not correct.I googled this, and have lost of disk space. The other suggestion was to remove and reinstall the gnome power app.I am not sure if this is the real problem, or if it is something to do with GRUB.There is some information on the system that I don't want to loose. I can get to a system console.
I don't know what bugzilla wants to know. I tried to create a new report, but I failed at the first page/question. THe page ask me to enter a classification. But I don't know want that could be. I check multible times but I got always just a big red EM. What's to enter at 'named tag' and at 'to bugs'?
I have a problem updating packages when using the kpackagekit systray notifier, it fails with the error "failed to obtain authentication".I've looked around and can't find any log output of this.If i start kpackagekit from the menu it all works fine, but not this way.This is with kubuntu 10.10, upgraded from 10.04, it did actually work before.
I am trying to setup Postfix along with dovecot on RHEL4. I have done the necessary settings in dovecot.conf, yet I am not able to log into the POP3 server. The error I can see through WireShark/Ethereal is "Err- Authentication failed" Some of the important settings in /etc/dovecot.conf are
i am using fedora 12(32 bit),when i tryed to uninstall program pidgin from system->administration->add/remove programs i got an error message saying tat YOU FAILED TO PROVID PROPER AUTHENTICATION,so i was jst wondering if we can sign in as root through gui.the problem with my pidgin app was that whenever i tryed to start that application, it appears for like 4-5 sec and then disappears! so i thought of reinstalling the pidgin.
Im using CenOs 5 and have install a mail system(postfix+dovecot),when I trying to enable selinux for enforcing mode and i'm have some issue, the user authentication failed. How can i to fix this problem?
Above mentioned is my configuration. when i try to connect client with SSH it is not sending a request for authenticating user to RADIUS server. what else configuration i have to do, or if there are any mistakes in my configuration
If your machine is connected to the Internet, you'll probably want to disallow ssh password authentication (which is advised but not mandatory). Edit the /etc/ssh/sshd_config file and change/add the following lines:
PasswordAuthentication no AllowUsers nx
Don't forget to restart the sshd daemon after making that change: service sshd restart I already have PasswordAuthentication yes in my file as I need it to login to the server through ssh. Do I just skip that line and only add AllowUsers nx mynxuser at the end? Also, I followed the rest of the manual and when I tried the client on Windows it failed: I put in a user and password to login but shouldn't it be using the key instead? I think the problem is related to the above due to:
NX> 203 NXSSH running with pid: 1428 NX> 285 Enabling check on switch command NX> 285 Enabling skip of SSH config files
