Fedora Installation :: F13 To F14 No Shell At Login / After Upgrading Cant Login On User?

Jun 3, 2011

yesterday I updated my fedora 13 to fedora 14 (on laptop) and today i cannot log in on user. It just go blank for a sec and is back to login.

At text console (alt+ctr+f2/f3) i enter my username and pass it give this for a sec and resets (clean) console
username: Name
password:
last used: [date]
login: no shell permission denied

i used unetbootin (fedora 14 netinstall to update) and later i updated 1,5G before reboot (did update that fix, forgot its name tho :s)

I would most likely reinstall everything, but i have some work at laptop and as death-line is near, i would prefer to fix it if possible.

edited:
i have installed F13 on unused space, is there a way for me to access and fix it? or at least get some files from there?

Fedora Installation :: Cannot Login To X After Upgrading To F14?

Nov 4, 2010

I can't seem to login to X after I've upgraded from F13 to F14 (x86_64 KDE Spin). I retained my /home partition with my user account etc.

The system fails when I try to login to the account I had on F13, but if I create a new user account I can login to X.

I did have the nvidia proprietary graphics drivers installed... how to track down an X issue like this relating to logging in to a system via the GUI?

General :: Login As Other User Using Shell Doesn't Load The Profile For That User?

Dec 11, 2009

I am using the sudo command to log on locally as another user by the following command:

sudo -u theotheruser -s
or
sudo -u theotheruser sh

As I see it, this initiates a new shell with the mentioned other user.However, this doesn't load that users profile from his home directory.Is there a way to automatically read the users profile when login in with selected command? I am mostely interested in getting a working prompt when logged in.

General :: Shell Script To Automatically Login Through Ssh And Create User?

Oct 20, 2010

I was trying to create a shell script which will automatically login to the server 192.168.1.7 and checks if a user exists there or not, if it doesn't exist then it should create the user.I have very little idea about shell scriptThis is what I tried:Quote:

#!/bin/bash
pass="sacharje"
ssh 192.168.1.7

Now, how to pass that password automatically to the ssh when it asks for the password? (I can't use public key authentication here)

Slackware :: VSFTPD User Versus Login Shell Definition

Jul 18, 2011

I'm using VSFTPD on my office LAN for one simple task: to receive-and send - installation images created with Ghost4Linux. Until recently, my main LAN server ran on CentOS, but I decided to migrate it to Slackware (nicer release policy ).

What I usually do is create an 'install' user who can login to FTP, but not on the system. Here's an example of what I used to do on my CentOS setup:

Code:

# mkdir -p -m 0700 /home/ftp/install
# groupadd install
# useradd -d /home/ftp/install -g install -s /sbin/nologin install
# chown -R install:install /home/ftp/install
# passwd install

The relevant bits in vsftpd.conf looked like this on the CentOS server:

Code:

...
anonymous_enable=NO
...
userlist_enable=YES
userlist_deny=NO
userlist_file=/etc/vsftpd/user_list
...

Then I only had to create the /etc/vsftpd/user_list file and put a single line in it to allow the newly created user:

Code:

install Now I've tried to get the same behaviour on Slackware, and I succeeded more or less, except for one thing. There's no way my 'install' user can login to FTP when his default shell is set to '/sbin/nologin' (or '/bin/false'). Only when I change the 'install' users' default shell to a "real" shell like '/bin/bash', he's able to login.

Here's a little practical demonstration of what's happening:

Code:

$ lftp localhost
lftp localhost:~> user install
Mot de passe :

[code]...

Fedora Installation :: GDM Login Screen - Cannot Authenticate User

Mar 23, 2009

Previously I have a hard disk running OpenSUSE partitioned as follows:
Code:
/dev/sda1 = swap
/dev/sda2 = /
/dev/sda3 = /home

I redid the default partitioning scheme that Fedora tries to use (no LVM crap). Basically told it to make the above layout and to format swap and slash, but NOT to format /home because I want that data. I had it go ahead and install grub on the MBR of this HD as well. The install seems to have went ok and it rebooted. That is when the first problem comes up. I never see grub. I just get a black screen then a bar at the bottom that progressively turns blue, which I assume is Fedora loading.

This is all well and good, then it gets to the login screen (GDM) and I try to log in as root and it tells me "can't authenticate user" hangs for a bit, then goes back to the log in box. I try to get a virtual console (Ctrl+Alt+F#) and nothing. So I guess I have 3 problems in order of significance:
- Why no grub?
- Why no virtual console?
- Why root can't log in?

Normally I would edit kernel option line at the grub prompt to boot into single user mode and fix the problem, but can't. I was able to use the "rescue mode" on the Fedora DVD to accomplish this, but have not had a chance to figure things out any further. I don't think having a /home created by another OS would prevent root from logging in since root "home dir" is /root.

Fedora Installation :: User Login Fails Completely?

Jul 23, 2009

Fresh install of Fedora 11 x86_64, ext4 file system, Intel Quad, 1 Tb disk

Went through install, defined mike as user with password

reboot, get graphic login (init 5); cannot login as mike OR AS ROOT!! (unable to authenticate)

use live cd, reset inittab to start at level 3

reboot, get user prompt on terminal at level 3

enter mike and password, system wait a minute or more, returns to login prompt (obviously timing out --- dbus problem???)

enter root and password, get in, issue startx

open terminal window, and issue "su mike" command, ten minutes later, finally get terminal with mike as user.

Use ctrl-alt-F2 to get a terminal, type mike, and password, no joy; login as root and type "su mike". Go back to Gnome screen at F7, so I can continue to type this , and check back at F2 periodically to see if "su mike" ever takes. After three minutes, still no joy. After five minutes, it worked. whoami shows "mike"

Fedora Installation :: Unable To Login Using The Only User Account?

Mar 29, 2010

If I'm getting good at anything with Fedora, it would be making mistakes. I have Fedora 12 installed and it was running fine until I attempted to set the path in bashrc and cshrc for jdk. Now I am unable to login using the only user account I created at install. When I enter my password the login screens goes blank then my mouse pointer appears with the circling dashed loading symbol for a few secs and then brings me back to the login screen asking for my password again.

Fedora Installation :: F13 User Lost After Creation - Automatic Login

Sep 28, 2010

I have a windows 7 ultimate host machine, installed oracle virtual box on it. Made a iso image to boot fr fedora. All this is fine when the installation is complete, it asks for reboot. Reboot done. Then I went to terminal. Did a SU - root to get into the root. Then I did a firstboot command to enter information. I created a user for myself and at the end rebooted the virtual box.

When it starts up, it does not show my user. It just shows "Automatic Login" and it logs in as Live System User. Even if I try to switch user then it gave me a authentication failure when I enter the credentials of the user which I created. If I try to create users manually using system administration, the user is lost after reboot. I have tried all possible steps...as instructed on the net.

Yesterday I did a successful upgrade to 10.04. Today, after a few hours of using and a few reboots, when I provide my password in GDM, the screen turns black and gets me back to the GDM. The same with recovery mode.When I turn onto the terminal I can't see any letters but a bunch of blurred lines on the top of the screen. In recovery mode the terminal works properly.GDM also works properly. Neither graphics, nor the resolution has changed.

Ubuntu Security :: Bad Login Protocols - Graphical Login For Gnome Sizes Itself To Accommodate A User's Exact Password Length

Dec 14, 2010

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.

Fedora :: Upgrading - System Not Allowing Users Login

Jan 30, 2011

I upgraded my Fedora Core distribution from 12 to 14. Everything worked fine, except for SQUID which refused to upgrade. I then went to rescue and installed SQUID using yum and then restarted the upgrade. It did finally upgrade the system and then asked for a reboot. Well, when I selected the new kernel option in the GRUB options, since I also have Winduhs, it gave a kernel panic. I tried booting into the older kernel and it worked. Now I see the users that are there in the system in the Graphical GUI login greeter screen. But none of the users get authenticated. I used the rescue option and removed graphical login and changed boot level to 3. I also enabled the root user. In the rescue mode, if I do a startx, everything works fine.

I logged off rebooted the system. When I login, I see the version is shown as Fedora Core 14, but the kernel was still the older one with Core 12. I again went to rescue and checked out GRUB and saw that it had no initrd for the new kernel. I created a initrd image with the mkinitrd command and then added it to grub. I again rebooted. This time it shows the correct kernel, but still the system does not allow any of the users to login. All the Logins fail. I have tried going to rescue and going to the system using 'chroot /mnt/sysimage' and doing a startx for Graphical. Everything works, but only with the Rescue mode in the DVD. The normal boot/login sequence does not work.

Incidentally when I do a 'yum distro-sync', I get something like this :

---> Package dialog.i686 0:1.1-9.20080819.fc12 set to be downgraded
---> Package dialog.i686 0:1.1-11.20100428.fc14 set to be erased
---> Package diffstat.i686 0:1.51-1.fc12 set to be downgraded
---> Package diffstat.i686 0:1.51-2.fc14 set to be erased
---> Package diffutils.i686 0:2.8.1-25.fc12 set to be downgraded
---> Package diffutils.i686 0:2.8.1-29.fc14 set to be erased

It still seems to believe its a Fedora Core 12 system. Another information is that when I leave rescue mode and do a normal boot without installation media, it starts doing some SELinux relabelling and reboots. Any pointers on how I can get the system working. I am able to work with the rescue mode way, with any user, as it does not ask for any password. I can even do startx and work on the GUI. All my data is also there. I just am unable to get the user authenticated using normal boot/login. I have tried using passwd -d username, but it gives an error :
passwd: libuser initialization error: could not open configuration file `/tmp/libuser.ElY0r9': No such file or directory
In fact, I am now in rescue mode only when I am writing and sending this.

My GRUB file is :
default=4
timeout=25
splashimage=(hd0,9)/boot/grub/splash.xpm.gz
hiddenmenu

Fedora :: No Shell After Upgrade - Screen Flashes On Login

Sep 29, 2009

I upgraded from fedora 6 to fc10 using a net-inst iso. Everything went great however when I rebooted gnome wouldn't start up and there were other error messages, however thats not my current question. I figured id login as root, I put my pw in and the screen briefly flashes and then back to login prompt. The flash is a message saying something about no shell. Same occurs when trying to logon to my main user account. I can boot to single user and see that all my partitions are there and the data is there. My password file has the shell at the end of the entries.

Ubuntu Installation :: Can't Login After Removing Other User

Aug 15, 2011

Ubuntu 10.10

I was setting up a machine for a friend using my normal username. Once the install was finished I created a new account (Admin) for the friend, logged out, logged in as the friend and deleted my own account. On the next reboot I get a message about not being able to update .ICEauthority for my own account, which I thought was deleted. Then there are messages about the configuration server failing and that Nautilus can't find the home dir for my own account, then just the desktop background, no panel, no nothing, just hangs.

Obviously, in this case deleting the account didn't clean up everything. How can I get to the login prompt for the friend's account?

Fedora :: Cannot Login To KDE As Specific User

Jul 17, 2010

I have a very peculiar issue - I can't log in to KDE as one particular user (andrew, which is my regular account) though all other users including root, mythtv & other family members can log in without any problem. When I try to login as andrew the X server appears to crash as the screen goes blank and I have to press Ctrl+Alt+BkSp to get back to the KDM login screen. The proximate cause seems to have been updating KDE to 4.4.5 using yum - I did this logged in as andrew in a terminal session using su - root, and the black screen problem arose next time I tried to log in.

I can log in OK as andrew using a different desktop manager e.g. Sugar. I am using radeonhd graphics driver; if I change to "vesa" in xorg.conf I can log in OK. If I change the home directory for andrew to that of another test user and change the file ownerships, I can log in OK. Therefore the problem must lie in a config file(s) somewhere in the andrew home directory tree, which is specific to KDE and also radeonhd. I have checked in all the obvious (and unobvious) places but can't find anything. There are no relevant SELinux errors or entries in syslog or Xorg.0.log. The .xsession-errors file from a failed login attempt is here [URL] it isn't significantly different from a normal one, and as the entries are not time-stamped I am not sure which ones arise during the login and which when I restart the X server. I am running F13 (kernel 2.6.33.6-147.fc13.x86_64) without any other significant issues.

Fedora :: F13 - Cannot Login As NIS User By Using Gnome Or GUI

Sep 24, 2010

I have a problem concerning about NIS. I have set-up a NIS client, but I am not able to login as NIS-user by using GNOME or KDE login GUI. However, I was able to login as NIS-user by using a terminal that's open from a local account or root. Also the NFS seems working as well. This problem only occur on my new FC13 pc, and I don't have this problem on my FC10 pc. Both of my FC13 and FC10 PC have the same NFS and NIS setting.

Fedora :: Cannot Login Other Than Root User

Jun 17, 2011

Well I did something pretty stupid and now I can't log in with my user other than the root user. Basically, I wanted to change my username and so I when to the admin > user & accounts - and selected the account I wanted to change. Anyway I did that and then logged out. Since then all I get when I reseted is a spinning mouse ball and a black screen. I can get into the shell prompt - but I'm not sure how I'd go about fixing this issue I created. At the moment I'm logged in the shell with root, and if I type 'id' I can see my old username, but I think the links behind it are broken.

Fedora Hardware :: 15 Nvidia GeForce Go 7400 Gnome 3 Shell Hang On Login

Jul 12, 2011

I've seen a lot of posts related to problems with GNOME 3 shell and nvidia drivers but I have yet to find anything that seems to fix my problem. At this point, the laptop, a Dell D850, boots just fine all the way to the gdm login screen. When I log in, the background and menus initialize and the mouse can be moved around, but nothing works---I can't click on anything, Alt-F1 does nothing, and I have to switch to a VT and shut-down X. I've uninstalled all things nvidia and now I have a working laptop, so long as I use Classic with Compiz.

I upgraded two other hosts, but both had ATI graphics cards; they worked without a hitch. I'm regretting having decided to upgrade this laptop

Debian Installation :: User Login Fails / Root Ok

May 26, 2015

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?
