One of my colleagues was working on my system (Centos 5.6). He deleted some files from the /tmp directory (he thought he was cleaning up files). Right after that, he rebooted the system. I now can no longer login.
Prior to this, here's what I see following a reboot code...
no matter what I use, I cannot login -- it takes me back to the (none) login: prompt
Any ideas? I know that deleting from the /tmp directory could lead to catastrophic results, but he thinks he only deleted a specific set of files.
We use Centos 5.3 which we deploy to dozens of boxes in different buildings throughout our shop. I set up KDE to be the default windows manager for these boxes, although the individual users can choose for themselves. We use LDAP authentication, and typically logging in through the LDAP into KDE goes without a hitch. However, a couple users are having problems logging in to their accounts through KDE, my boss and my boss's boss to be specific. We have NFS shares which serve up each users home directory regardless of where they connect in our system. When my boss, or his boss, try to log in, they put in their credentials, and LDAP accepts them, but KDE never starts. The splash screen which displays that it's "initializing system services" or "loading desktop" doesn't even come up, it just has a picture of the desktop with a cursor, and hangs there. I've tried deleting the .kde directories in their home folders, but that doesn't work. Those two are the only accounts out of our entire system that have problems logging in to KDE, and I have no idea why! I've looked in the .xsession-errors file, here's a copy code...
I know it isn't the xset or "no profile" errors because all the users I've checked get those too, but they can log in just fine. Both xsession files on both users are almost identical to this one, it just seems that KDE will never start.
Decided to give Unity desktop a try this afternoon on my Maverick desktop - bad mistake. Found it very slow so I removed it. After that I restarted and all I get after logging in is a white screen.
I don't get an option at login to use KDE or anything else for that matter, so I'm hoping someone can give me some idea how I can rectify this.
Really don't want to wipe the install and start over because I don't have a separate home partition (think I've learned my lesson on that front) and there's a lot of stuff I need to keep on this machine.
Does anyone know a way to activate a screensaver at the login screen? I've got about 5 machines here, and I'd really like the ability to just have the screensaver come on after 5 minutes of sitting there with nobody logged in...
Even a way to blank the screen would be nice. However, if we were to blank the screen, I need to ensure that it doesn't do a DPMS blanking, since we use calibrated monitors here, and turning them off sucks.
I recently installed Deluge 1.2.0 from the following PPA:[URL]I using this on two different Linux computers. One is running Linux Mint 8 and the other is running Ubuntu Netbook Remix 9.10. The first time on either computer when I enable WebUI in the Deluge GUI it works fine. However if I ever disable it in plugins section I am subsequently unable to re-enable it (doesn't appear in the side panel again). Rebooting or reinstalling Deluge seems to have no effect.Is this a bug or am I doing something wrong?
A problem with installing CentOS 5.3 from DVD ... I downloaded the CentOS-5.3-i386-bin-DVD.iso, after recording an image on DVD Start the installation, selecting Installation Method, chose Local CDROM - Message on my screen: "CD Not Found"
I am unable to boot my server and it is erroring with the message "Kernel panic - not syncing: Attempted to kill init!". Here are the details:
I have a brand new Dell PowerEdge T110 server with Quad-Core Xeon CPU and 2GB 1333MHz RAM. I have installed a hard disk (SATA, 7.2rpm) on this machine that I removed from another Dell PowerEdge T100 server with Dual-Core Xeon CPU that was running software RAID 1.
Now when I boot the new T110 server, it displays the following error messages code...
I am running CentOs v5.5 x86-64. If I put the hard disk back into T100, it boots fine. I do not know why it is not working with T110 server.
I'm running CentOS 5.5 with a hardware Areca controller (Raid 10). I initially installed a machine and rsynced the file system to a third machine; I'm then pulling in the file system to new machines and updating grub with a script to make it bootable.
I've done this before with other machines (no raid sets) but with these machines I'm running into errors code...
I have an NIS server that is working well, and I want to use Kerberos to improve the overall security.I have already installed Kerberos client and server on two machines respectively.Currently the NIS server, Kerberos server, and KDC are running on the same box, and every box is in the same private network.I am having trouble logging in using the user account defined in Kerberos database. Here's /etc/krb5.conf on the client side:
Everything was fine yesterday, but today, the situation is the following:
When I try to login as root, using Gnome, after I enter username and password, it can do three things:
1- It brings me back to the GUI login screen again
2- Brings me to the prompt login screen (black)
3- It lets me in but I have no top or bottom navigation bars. (Sorry, cannot remember the actual names...) Sometimes I have access to a console screen, which allows me to reboot, and sometimes not, in which case I have to do a cold reboot. Not good.
The last attempt I made, I used the KDE interface and everything was fine.
I really don't understand what happened between yesterday and today, nobody but me uses this system at home and remote logins for root are disabled.
I had successfully installed centOS,i am able to login as root.I created local users.But unable to login via console and FTP.As per the logs there were some LDAP issue,so i disabled LDAP and disabled PAM config as well.Now i am able to login to the FTP with the local users created.unable to login to the centOS console with the local user.
am running centos5.3 on a virtual machine and was trying to do some basic hardening and part of it i had to modify the pam.d/system-auth file and from then i am getting a fatal error whenever i try to connect via ssh using putty i am not at all able to login the server with any of the accounts even root also.I am scared unknowingly did i lock the system???how to resolve this issue?
I recently powered up my netbook... Selected my user log in, entered my password, and after a couple seconds I briefly see what looks to be the console and am returned to the login splash screen... I can Ctrl+Alt+F2 to get to the console and log in... but that is as far as I can get. This is the case for Gnome, Remix, and Remix 2D.
I can sudo apt-get (update, upgrade, etc) as well. It is the right password because if I type in a wrong one it presents an authentication failure dialog box.
How can I fix my log in screen and get to my desktop? I am Currently running 10.04.... waiting to get 10.10
I am not able to login to server from console attached to server, every time i enter username & password but it again asks for username & password. But when i try to login to server from remote machine, login happens properly.
System was fine with :Ubuntu 9.04 (had also installed kde )then....I wanted to try some change to gdm so i downloaded gdm while building it , it asked "PAM" libraries to be installed so i installed PAM ... but ignored the instruction to reinstall SHADOW (library i guess..),Now :on booting system i get login menu but i am not able to login , it says some critical error occured
1) install new copy of UBUNTU and remove old
ps :1) i can log into system through live cd
2) i can use recovery mode boot and log into terminal as root(startx is not working from this terminal..
I have an iMac G4 that I installed Jessie on successfully. However, when it boots, one of the last messages is:
[FAILED] Failed to start Load Kernel Modules.
Last line is something along the lines of:
fb: switching to nouveaufb from OFfb NVDA,NVMac
And then the text starts dissolving, and the entire screen cycles through different colors. I presume it is sitting at the graphical login prompt but it's not displaying correctly.
Based on some Google searches, it seems like I should be able to resolve this by editing /etc/modules but I can't get to that point. I have tried to get to a terminal using ctrl-alt-F1 through ctrl-alt-F12. No luck. I tried different yaboot options that were supposed to avoid using the video driver. No luck. How do I get the machine to boot straight to a regular text login instead of the X one?
This machine worked fine running Mac OS X this morning, so I don't think it's the hardware. What I can do.
To enable automatic login, I edited the /etc/gdm/custom.conf file and entereted the following lines:
Code:
The automatic login is working but I still see the login box with options to select language. After a delay of few seconds, the system will automatically log me in. I don't know why I see the login window. Is there any way to bypass this window?
New user, just installed last evening. Ran fine, then did update. rebooted computer, see logo, but login screen is dark black rectangle, can see anything.
Trying to power down computer yields message that gdm-simple-greeter.desktop is not responding.
Tried do CTRL-ALT F2 (found in forum) and issue commands sudo /etc/init.d/dgm stop dpkg-reconfigure gdm - but get error message "/usr/sbin/dpkg-reconfigure must be run as root"
So, I can run command line, but no gdm. Any ideas? And I am a neophite with Linux.
How can I enable telnet login in a slackware derivative? (specifically Backtrack 3)Needing telnet because I'm unable to get ssh login working through a reverse ssh tunnel.
I have installed both GNOME and Cinammon Desktop Environments in Debian, using the latter as default. I would like to switch to GNOME DE, but there's no session menu (as in Ubuntu/Mint...) available at login.
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.
