Software :: GDM: Users Disappeared From Login Box?
Jan 14, 2011
PC conked out the day before I was due to leave the country, so in the few hours I had to try and knock up a solution, I set up a very old second machine in the house running openSUSE 11.3 with XFCE. I'd previously replaced the default login display manager with GDM, which evidently has various bugs. Aside from the cursor continually spinning around showing as busy, when I added a new user account for my parents, the login box showed two entries under my own name. It's only on hovering the mouse over the latter entry that my parents' username shows up. Anyway, I had to explain this and a million other quirks to them in a rush, but the system was all working and they managed to get me an email from it the following day.
Since then, however, when they reach the login screen they say there is just an image of a computer monitor, with the OS version and domain, but no usernames to choose from or other options anywhere, and hence they can find no way to login. I have no remote access to the machine and can only talk over the phone. I suggested a few key combos to see if anything happened, and they booted once in failsafe mode, but no luck.
What could have happened? Is there a key that would show the users again? Perhaps there's a way to get to a console login, but could they get back to a GUI easily after that? nfortunately my parents are really not adept at these things and every instruction I give has to be repeated endlessly after which they usually get it wrong a couple of times first, so trying to do anything administrative or more clever than a few key presses or mouse clicks is going to be nigh on impossible. Running a live CD would be likely out of the question since they'd need to change the BIOS boot order first
Last week my parents' PC conked out the day before I was due to leave the country, so in the few hours I had to try and knock up a solution, I set up a very old second machine in the house running openSUSE 11.3 with XFCE.

i have a NIS master server and 4 NIS clients. out of 4 nis clients two are acting as login servers ie users will login and do all their stuffs and the remaining two are application servers. But sometimes users login into applications servers and started doing all their developer's job. i want to allow only a limited number of users tointo this application users not all the users who are all part of the nis domain.all the systems are running RHEL 5.4 on hp's proliant x86_64 based servers. Please advice me how should i proceed? enabling ip tables is not possible in my environment.
I've set up password-less login for user1 on a Ubuntu machine to login automatically into a Fedora box using the publickey authentication method. Everything is working smoothly. Now, there is a user2 on Fedora but he does not have an account on Ubuntu.
I tried to login as user2 from Ubuntu to but got the following error :
Code:
Predictably neither scp or sftp work either. I have several questions as a result.
1.Is the SSH server rejecting user2 login because I am inadvertently using user1 keys (as I am logged in as user1) ?
2. Do I need to have a user2 account on Ubuntu and public/private key authentication setup with Fedora for user2 to be able to login ?
3. Is there a method I can use to password login as user2 from Ubuntu to Fedora (even though there is no user2 account on Ubuntu) AND still keep password-less login for user1 or do I have to have password-less login for both ?
At present the only way to access the user2 account from Ubuntu is to SSH using the user1 account and then su to user2.
I've been fiddling with a number of things the past day or two trying to get samba working, now it seems to be, but in the process of tinkering with that 've developed a new problem. Its hard to pin-point when it happened as all I know is that I restarted and was no longer prompted for any kind of password. I have been searching google for a few hours and have only found ways to make this happen on purpose, but not necessarily anything to reverse it. If somebody has any idea what has happened here This is really frustrating. I liked loging in with the keyring as opposed to the login screen and I would like things to go back that way.
I installed the pam_face_recognition package to try out but decided couldn't get it working properly so removed it via YAST. Now when I boot up I get a pop up dialogue saying the login greeter widget is missing and to check my configuration. Clicking OK on the pop up drops me to the console login.
Let me reassume what I just did, because it will be easier for you to understand my problem. Today I played a bit with my Ubuntu (10.04, latest kernel) because I wanted to try xmms. I tried to install it manually, but since i couldn't make some libraries work I went for
[Code]....
I don't know where something went wrong, but when i rebooted my GUI disappeared. I'm stuck in login screen with nothing in there. I tried to do this [URL].... , but it doesn't work (if i'm not wrong those folders are inside /home, so after login I have to do [cd ..] and then using the rm command) I tried also pkill gnome-panel before coming back to desktop, but it doesn't work either. I tried to
Code: sudo apt-get install ubuntu-desktop but it says I've got the latest one already installed.
I used KDE3 with 11.0 with some KDE4 apps till I needed some applications from the KDE4 factory tree and mistakenly left the repository active. Next time the online update also updated most of the applications I would rather keep, and as a result the KDE3 disappeared from the KDM login choices. So I have two questions:1. how to enable users to select KDE3 at login (currently I have to select failsafe mode and run startkde manually)2. how to replay back an update I didn't want to have?
Perhaps a combination of the above: can I upgrade to OS11.2 and keep KDE3? (please don't tell me to switch to KDE4, I acknowledge and appreciate the effort and the improvements that KDE4 got, but it's still not a replacement for KDE3 - there are so many simple things which are impossible in the new version)
Just installed Debian on a laptop. I'm not a Linux noob, been running Ubuntu / Kubuntu / Fedora elsewhere for a while. But first time with Debian (Gnome). [Broadly pretty happy so far. It may supplant Kubuntu on my desktop as the latter seems a bit of a resource hog.]I want the login screen to offer a list of users.I've tried System > Administration > Login Window > Localand chosen Themed with face browser from the dropdown marked Style:I'm using Bijou (though I've also tried some of the others) as my theme, in case that makes any difference.I haven't got any pictures set up for users. It's not particularly that that I want, just a list of users to choose from rather than having to type in your username each time. It's a family setup, no big security worries, so easing typing would be nice.
I've recently installed Ubuntu 10.4 - and used it quite successfully as the adminstrator user. But when I add additional users they can't login - to be exact, their password is accepted, and they get a screen with nothing except Ubuntu's pink/purple background.The mouse pointer moves around but clicking the mouse does nothing.
I have an RHEL 5.3 system where NIS logins are working perfectly, but authentication doesn't seem to be working for non-root local users. I can't login either remotely or at the console with a local user, and I can't even su to them unless I'm doing so from root (i.e. when no password is required).
I've reset the password, I've deleted and recreated the user, and nothing. nsswitch.conf does have "files" listed as part of the config, which was really the main place I'd have assumed the issue could be. su gives "incorrect password", and ssh gives "userauth failure". /var/log/secure shows "su: pam_listfile(su:auth): Refused user <username> for service su", and same for the ssh attempts (with ssh in for su, of course). I've reviewed my pam.d files, and they seem to be the same as on a working machine, but I'm not 100% conversant with pam so I might be missing something.
I need to create a number of internal Linux users for admin purposes. I do not want these users to appear on the initial console login page just after Fedora boots up, as users who can attempt to log in, and I do not want to allow these users to log in directly. I merely want these users to be accessed via su, just like the root user.
Meaning when I turn on the computer, it automatically logs into the family account; and they never need to enter any passwords.Second, under System -> Administration -> Users and Groups (users-admin from terminal) there is a "Don't ask for password on login" option (toggle) which is desirable for this family account. However, I have never seen this option enabled, but always grayed out. Is there any way to enable this option?In short, I want:1) For the family account never to require a password on login.2) Automatically log into the family account on boot.
I have a fair number of users created for running processes (apache, oracle, etc) and they appear in the login screen when I boot. Is there a way to not display them?
i have a postfix mail server in my office and mailscanner. recently i changed the password of mailscanner's admin login 'mailwatch' and now i m unable to get login in postfixmail scanner. even i changed the password of mailwatch user from mysql database, bt it does not work. get login into mailscanner to chk the mails of all users.
I'm trying to get samba working on a debian/xebian box to use as a fileserver. I have a HTPC which is win 7 and a laptop which is OS X. I've installed SWAT and Samba to manage the whole settings. I'm trying to get it setup so that there's a user which has access to my ~/ and a guest user which just has read access to ~/Media/ so that the Media centre can read all the files from it without having to login.
The problem is when I have map to guest set as NEVER I can access the samba ~/ and I'm asked for a username and password which I login with fine and can access the files on both share ~/ and ~/Media. However when I set the map to guest to bad user or bad password I can access the share for ~/Media. But when I try and access the share ~/ I don't get any login box and I immediately get the error "Can't access share permission denied" or an error along those lines.
Here's my /etc/samba/smb.conf # Samba config file created using SWAT # from 192.168.1.65 (192.168.1.65) # Date: 2010/07/10 20:39:16
# Global parameters [global] workgroup = MS_HOME server string = %h server (Samba %v) obey pam restrictions = Yes passdb backend = tdbsam, guest passwd program = /usr/bin/passwd %u passwd chat = *EntersnewsUNIXspassword:* %n .....
How to get it working so I can have a guest share for my HTPC and a logged in user for my private files?
i've written a bash script to add new users to our system. the script works so I won't bother you all about that. when a new user is created with it, they can immediately login to our domain from any terminal, which is good. However, the newly created user is unable to login to debian at all, and so cannot access the server. when attempting to do so, they get a message like "the system administrator has disabled your account". This is a good thing really as normal users have no need for debian login, but I do need to add a few admin users who will need direct access to the server machine.
This is the code I'm using to add the user. The rest of my script is just a wrapper and GUI. I figure the login shell may have something to do with it, so I tried changing the shell of a user to the default /bin/bash. This resulted in the user being able to login - sort of. Gnome doesn't load though, and there's a cascade of errors across the screen about things failing to save or load settings. mostly stuff like nautilus, X, and gnome. the desktop background is black and there's no interface. Logging in with a previously existing account works fine though. Clearly I have an issue somewhere.
I am switching to Gnome because its look and feel is closer to Windows for my workgroup. LDAP and NFS are working fine with KDE and SSH. but I cant login with LDAP users both directly or via NX client. When logging in directly on the server it shows this error:
Code: "Xsession: Login for <user> is disabled " When logging via NX client it says, it authenticated successfully and then quited with this popup message: Code: Could not connect to session bus: Failed to connect to socket /tmp/dbus-0frstajyNE: Connection refused I closed this popup window and one more appeared: Code: Could not acquire name on session bus
Description: I want to migrate all home directories and users from one webserver to another. The old server runs OpenSuSE 11.2 and the new one OpenSuSE 11.4. I appended only the userpart of the passwd file from the old server to the new one. I did the same with the shadow file and the group file. I checked the user rights for all three of them and they were ok (shadow 600). I have done such a migration before and at that time it worked fine. Now for the weird part:
Errors: At first it seemed everything was ok. Websites and webshops were visible and working correctly. At first ftp seemed to work fine. Login worked but when uploading files, the error messages appeared: permission denied. Further testing gave following results:
-Root and users can login on console with their old passwords.Root can create new users, but they can not login: some error message comes, but is unreadable since it stays too short on display. After that it prints hint: on a new line and on another new line it gives a new login prompt. Root and users can change user's password, but then they can not login anymore. The same unreadable error message appears. -Users can login with ftp, even after changing passwords(!) but can not change or add files var/log/messages only shows: uthentication failure twice.
Actions so far: Emptied /tmp reboot copied the users again from passwd and shadow checked UID's and GID's again googled a lot
I created some users on my Ubuntu 10.0.4 machine a long time ago (whilst experimenting). Some of these users can login to the system, and others were prevented from login in. I can't remeber which ones can login. I have the following questions:
How do I find out which users may login to the machine? How may I disable an existing user account from login in? How may I re-enable a previously (login) disabled user account so it an login again?
I have a small problem regarding multiple X sessions. I want 2 X sessions started automatically on boot with 2 different users auto logged in and 2 different sessions running.
On first X session I would like to have gnome running with user1 On second X session I would like to have xbmc running with user2 So far my computer logs user1 in to a gnome session via gdm on boot. But then I have to launch a tty, log in as user2 and then start xbmc in a new X session.
How to make it work? I would also love to have the second X session active after boot. I am running Ubuntu 10.04.
When you boot up Ubuntu, you are presented with the login screen, with a list of users that can access the machine. I want to be able to only show certain users in that list, and hide others.
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.
This is my quest: i need to install a box with a proxy server where useres can login, register what those users have been doing on-line and generate a dailly activaty report... I have been googleing for days and so far a tried out zeroshell (no reports) and untangle (no login)...
Error message in /var/log/messages login(pam_unix)[26769]:session opened for user root by LOGIN(uid=0) login[26769]: Module is unknown init: open(/dev/pts/0): No such file or directory
I have created a new user also but I couldn't login to the system. But I could login to the system as root and also with same new username password through putty from another machine.
I am trying to set up a network where users can login to a central server which gives access to a partition depending on their role in the company e.g development or HR.my ideal world would be a computer sits on the desk. someone comes along logins they have all their files. they can then login with the same user information else where in the office.
The login screen does not accept the password for users. Only the password for Root. The problem is not in the command line, but check the password in the screen. I have tried to change the password from the root and it is still the problem. What I can do?
