CentOS 5 :: Get "Authentication Failed" Error When Logging In?
Apr 19, 2011
I'm taking over support on some linux machines at my work. I came across a CentOS 5.4 system that my users can't log into anymore. When I try to login as root at the console, I get an "Authentication Failed" error message. If I ssh, then the connection terminates. When I type the password incorrectly, I get the usual message about entering the wrong password, so I know my passwords are correct. These are all local accounts, not NIS or anything.
What I've done so far: I booted into rescue mode and changed the root password. No dice. I booted into single user mode and tried updated pam. Again, no dice.

I got a problem with my CentOS server. Somebody told me OpenVPN Requires different changes inside my firewall settings. That could be the problem why openvpn wont load..I receive this error on my CentOS panel when im trying to connect into the centos openvpn (with my winxp pc):

I'm wasting hours on this problem: I'm setting up an always-connectable VNC server loaded via xorg.conf.
This is what I did: yum install vnc-server

I'm extremely new to SuSE Linux. I wanted to move away from Windows and so I decided to reload my Desktop with SuSE linux.I have had no trouble until now. I'm trying to connect to my work VPN connection. From my laptop (which unfortunately is Vista) I'm able to connect without any issues. However, when I tried out the KVPN application on my SuSE linux, it just doesn't work. I get the error:
Authentification has failed.
As a side note, when I type ping google, the packets are received 100% but when I ping my company address, no packets are received. Hope this info is useful.

If I am running a script, let's say a install script. Is there a way to make Su repeat authentication rather then just returning "Authentication failed" and continuing the script?

I've been using Ubuntu since 6.04, not a linux guru by any means but can usually get myself out of trouble.
So, the issue... I installed 8.04 on my mother's laptop some time back as she was having trouble keeping Win 2000 running (she has a low spec no-name generic laptop btw). I live in Autsralia and she in England, i thought i could better support her if she was running Ubuntu... All has been well with 8.04 but with the new LTS release (10.04) i thought i'd talk her through the upgrade... Did the online upgrade via Update Manager, all seemed to go OK but when she went to log on after restart she got an error saying 'authentication failed' even though we are 100% sure we have the user name and password correct... Tried to do a ctrl+alt+F1 to by pass the GUI log on but couldn't get the terminal session to open up, just got a black screen - no command prompt.
So... thought OK re-install... downloaded the ISO, burned and sent her a CD in the post... talked her through the re-install, all seemed to go well (again) - BUT, after restart, couldn't log in "authentication failed" again...
So, remember i'm trying to talk a novice through all this... any thoughts!?!
If i can get her to log in i can then support her via some kind of remote sesion or other screen share... and it wont cost me a small fortune in international calls!!! But if i can't get a log in, i'm dead in the water!?

I had a LiveUSB of CentOS 5.5, so I decided the install it.With no installer,I just copied the files to my hard drive.his was in a multi boot with Windows 7, Ubuntu 9.10, and FreeDOS.I updated GRUB2 and it detected CentOS. I loaded my entry and it failed to mount the root filesystem.I took the initrd0 file from the LiveUSB syslinux folder and added that ramdisk to the entry. Now it finds the root filesystem (/dev/sda9 as Ext3).But it fails shortly after loading /sbin/init. It talks about an init error where it says "File not found!!!".The previous lines involved umounting old filesystems, like /dev.

I receive the same result with the original e1000e driver from the distribution, the latest elrepo driver and the latest driver from Intel site (as seen in the example). I have tried also 2.6.37 kernel version - with the same result. The adapter however works fine under Windows (MiniXP from Hiren's BootCD) and with Ubuntu 10.10 LiveCD.

I wanted to install it on a secondary computer in my house for web browsing and little-to-nothing more.
How can I fix or get around the error 'Authentication failed' when attempting to login?
I just installed openSUSE. The installation seemed to go well. After installation, everything loaded up and I was using the OS with no problems.
I restarted the computer to change my boot sequence in the BIOS. Then I got to the openSUSE login screen. I was presented with three options:
1. my username - When I enter in the password I specified during the OS installation it says "Authentication failure"
2. Automatic Login - just says "Permission denied"
3. Other... - Nothing seems to work here
How can I login?
