Red Hat / Fedora :: Authentication Failed \ Unable To Log In As Root Or Any Other User?

Nov 12, 2010

I was trying to install winbind on a RHEL5 machine and I had to reboot the RHEL machine. When it came back up, I'm not able to log in as root or any other user.When I use root and give a random password, it says invalid username or password but when I use the correct password, I get an Authentication failed pop up box (under GUI). SSh window says invalid password for random passwords and the SSH window disappears when I type in the right password.Can you please let me know if I can somehow get back in by stopping any of the services

Ubuntu :: FreeNX Authentication Failed For User?

Sep 24, 2010

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

Ubuntu Networking :: Nomachine - Authentication Failed For User X

Jul 12, 2011

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.

Ubuntu :: Chown As Non-root User (with Authentication)?

Sep 19, 2010

I am currently responsible for administering a shared Ubuntu machine with several unrelated users. Some of these users own multiple accounts and would like to "chown" files between them. Currently, I must handle such requests manually, and this is inconvenient.

I am looking for a way to allow non-root users to chown files with authentication (i.e. prompt for the password of the user to which ownership is being set to). This would prevent an exploit such as:

Quote:
cp /bin/bash ~/sudobash
chmod 4777 ~/sudobash
chown root:root ~/sudobash

Does such a solution exist?

Fedora :: Unable To Login As Root Or Any Other User?

Jul 6, 2010

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)

Red Hat / Fedora :: Unable To Login As Root User In F10?

Jan 14, 2010

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

Fedora :: Unable To Root User In GDM Face Browser?

May 30, 2011

I'm trying to get the "root" user to be included in the list of users that get displayed on the login page.

I found this:[URL]...which seems to indicate that if I add an "Include" line, with the "root" user, that would work. I found the /etc/gdm/custom.conf file, which was empty except for the section header lines, so I added an "Include=root" line, but even after rebooting I just get the regular users, and have to login by typing the "root" username, etc.

So, I was wondering, is there a way to get this to work? P.S. I understand about not wanting to allow root logins, but I need to do this in my situation.

Debian Multimedia :: Authentication - Root PW Rejected / User PW Accepted

Jun 21, 2015

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!

Fedora Installation :: Unable To Boot Or Switch User To Root On Fc13

Aug 18, 2010

Having just installed fc13 and downloaded the KDE package I attempted to log out as user and back in as root, but I keep getting a message about the wrong password. This is odd as the same password works in terminal if I try to become a SuperUser. I have tried turning off SELinux to no avail. I cannot log in from cold as root,only as user.

Red Hat / Fedora :: Unable To "su" To Root When Logged In As A Normal User?

Jan 5, 2010

I have a Red Hat 4 server with Sungard Luminis installed on it. I was following some instructions on setting up Luminis to start at boot. One of the steps was modifying the sudoers file. Since modifying the sudores file, I am no longer able to "su" to root when logged in as a normal user. When doing so, I get su: incorrect password after putting in the password. I have another server with the exact same setup, broken one is test, the other is production, that works just fine. I made no changes to my production server. I've been looking at different things all day and the only difference I have found between the two are the results I get from running rpm -q --verify coreutils. Running that on my prodution server returns nothing. Results from my test server are below. Is this what is causing my problems? If so, what's the fix? I haven't found that yet. I've checked /etc/pam.d/su, both servers are the same.

rpm -q --verify coreutils
.....UG.. /bin/basename
.....UG.. /bin/cat
.....UG.. /bin/chgrp

The users/passwords are setup on Linux file system without MQSql or any other database. SASL etc is not configured at all.

Ubuntu Installation :: 9.10 Failed To Update - Unable To Mount Root FS

May 25, 2010

I wanted to try out the new Ubuntu 10.04, but since I don't have any CD's available I thought I could use my 9.10 CD and upgrade from it.

1. Installed 9.10 on the entire disk.
2. Went to update manager(?) and clicked the button to upgrade to 10.04
3. It successfully downloaded all the files.
4. When installing the new files it suddenly said that it failed to update, and it stopped. Then I went to do a hardware test, but none of the menus were working.

I had to do a manual shutdown, and reboot the computer. This time I was met with an error "Unable to mount root fs".

I figured the upgrade was the problem, so I reinstalled 9.10 to try without upgrading.
1. Reinstalled 9.10 on the entire disk.
2. Went to update manager(?) and started the normal update for 9.10 so the system would be up-to-date.
3. Same thing happened now, it fails to update and it makes my computer useless.

I've already checked my hardware for errors, can't find any. I've checked the CD for errors, can't find any. I had 9.04 on the same computer a few weeks ago, and it was rock-solid. Worked like a dream. I'm using Win7 now though.

Ubuntu :: Unable To Boot The 10.10 - Mounting /dev On /root/dev Failed: No Such File Or Directory

Feb 9, 2011

After upgrading from 10.04 to 10.10 I have had some problems booting my Ubuntu. It all started when restarting after the upgrade, and I got the error;

Code:

mount: mounting /dev on /root/dev failed: No such file or directory
mount: mounting / sys/ on root/sys failed: No such file or directory
mount: mounting /proc on /root/proc failed: No such file or dirctory
Target filesystem doesn't have /sbin/init.
No init found. Try passing init= boot arg

BusyBox v1.13.3 (Ubuntu 1:1.13.3.1ubuntu11) built-in shell (ash)(initramfs) After searching the Internet, I found a "solution". I just had to boot with a USB stick with the Ubuntu Rescue Remix (the normal Ubuntu USB won't boot either), and i wrote;

Code:

sudo fsck /dev/sdb5

Now I could start my Ubuntu again. So whats the problem? If I turn off my computer the normal way, there is no problem, but if I log off, put it into sleep mode, if something happens and I have to turn it off with the button it goes back to the first problem, and I have to reboot it with the USB stick and fix it all over again! If I don't have the USB stick with me, I probably wont be able to use my laptop!

Fedora Security :: Root Login Via Ssh 12 Password Authentication?

Jan 27, 2010

Can't seem to do it, wondering if anyone knows how? Normally there's something in sshd_config that can be switched to true or yes to allow root login but I can't see it in fedora 12.I can login via root at a terminal no problem, just not via ssh, I get access denied every time. Also, I need to login using password authentication.I've done: 227169 but that's just for GUI which I don't really need since I rarely ever log into the GUI.I have also searched through here and mostly only found info such as above, how to enable root login for GUI, or billions of posts about how logingin as root is bad but I cannotswer to my question.DISCLAIMER: Please do not reply to this thread if all you can contribute is the question of why I need root or to put some message telling me I can do everything using su, etc, etc. Please only contribute if you can answer my question. A: My machine and a valid quesiton. B: Spirit of Linux is open, not restrictive

General :: Authentication Failure For Root Logins (Fedora 12)?

I just got Fedora 12, and I used su root to change the bin ownership to my primary developer account. For some reason, though, all subsequent attempts to log in as root have had authentication failure, be it through su or through the startup login screen. This does NOT occur for adminstrator tools such as Groups and Users.
