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 188.8.131.52-147.fc13.x86_64) without any other significant issues.
Can advise if I want to have a alert message when a specific user is login to the system , what can I do ? that mean if a specific is login to system then send me a alert message ( by any way ) to inform me the user is login , what is the method ?
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?
i am using openssh 5.2-p1, i want to restrict user "admin" to login to the server from a specific IP address, for this purpose i have tried the following blocks in sshd_config file.Following is the part of the sshd_config file which i have modified
#The following commands will only allow specific IP to login to ssh.
#AllowUsers admin user1 user2
# override default of no subsystems.Subsystem sftp internal-sftp
Match Group sftpgroup ChrootDirectory /home AllowTCPForwarding no[code].....
i want to restrict admin user to login to the server only from 172.16.100.221 IP which can be done by using AllowUser line, but i dont want to use AllowUser line,
How do I give permission to a logged in user to stop/start a specific service without entering a root/sudo password? So they can do a simple "service SomeService stop|start" It is for a headless Ubuntu server.
my system I want user1 and only user1 to be able to mount and unmount a specific partition, this partition contains backups and is usually mounted read only, needs to be temporarily mounted read/write by user1 while doing the backup.user1 is an unprivileged user. I've read that the user option will let any user mount the file-system (and only that user can then subsequently unmount it) and that the users option allows any user to mount or unmount the file-system.I also found this in mount's man pageQuote:The owner option is similar to the user option, with the restriction that the user must be the owner of the special file. This may be useful e.g. for /dev/fd if a login script makes the console user owner of this device. The group option is similar, with the restriction that the user must be member of the group of the special file.So it looks like I'd need a login script for that user to make the user owner of the device file (/dev/voiceserv/backup in this case)
I want to know, how to allow to a specific user to run an application (for example Virtual Machine Manager) without entering a password? I have tried to add this user into appropriate groups, but it didn't helped.
I have installed gpg (GNU privacy guard) Now I have done this in root and therefore it was installed in the folder /usr/bin/gpg Now my other non-root user accounts have all functionality except main ones (ls, mkdir etc...) disabled. I require more functionality on this websever, especially to enable the use of the binary gpg How do I enable these commands for that specific user? I have tried to figure this out for so long,
I have a network set up that has been working for around a year with no problems but has now developed a login problem. The system was set up with a main server with all users on it and another PC located elsewhere that people could log onto using there personal login and password that then gained access to the account on the main server. This remote PC has now got the problem. When you try to log onto an account it comes up with the message "your session has lasted less than 10 seconds. If you have not logged out yourself this could mean there is a installation problem or that you are out of disk space."
Error message says that no profile for the user can be found and it couldnt create per-user gnome configuration directory. I can log on as root onto the remote PC as it is obviously a local account but all the account on the main server are not accessible. From the root account I can see that the connection to the server is OK and I can actually log into the accounts on the server using the failsafe session so the physical network is OK.
I never built or designed this set up and to be honest I normally work with windows so its all a bit strange to me. Both PC's run Centos 5. I have checked the messages log and there doesnt seem to be any indication of a problem. Just that it stopped connecting from the remote PC. The accounts are all active on the main server itself and have no problems being accessed.
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.
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.
I've recently upgraded my hardware. Now, the system boots perfectly fine, but I can't login to the tty as root or any other user. Infact yes, I can login, but as soon as it shows Last Login, it exits and then I'm back to a login prompt. I've successfully booted into single user mode, and changed all the passwords, but still it fails. X doesn't start, although I think it's due to the old xorg.conf having the wrong driver.
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 tried to change the name of the default user I created when I installed Fedora 14 to" Administrator". That apparently succeeded, but the login screen still shows the original name I specified. How do I go about changing that. don't need to change the home directory or anything else for that user.
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
I created an account using the following command:#useradd -g developers john and successfully changed the user password with:#passwd johnThe user is unable to login using the New Password using SSH. As a root I can login (#su - john) with no problem.
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.
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"
I am a new Linux user and have a question about the administrative authentication. When I am logged in as a user and I need to do something that requires root privileges the little password window comes up and I enter the root password. My question is how long are the root privileges granted for?I noticed that a few minutes after finishing checking out the firewall configuration tool and closing the window that I was still able to re-enter the fire wall tool and other administrative tools. How do I log out of the root privileges without logging out and then back into my account?
Does anyone know a secure method for starting a service after a user logs in to the desktop environment? There are a couple of issues that I'm trying to work around / troubleshoot and this would assist with doing that.
I'm running Fedora 11, not sure if that matters for this question.
