Ubuntu :: Login Password Keeps Changing?
Jul 6, 2010
Last night I had rebooted my machine and when it came back up it would no longer accept my password. My 7 year old son had been playing on the machine earlier so I assumed he inadvertently reset my password to something else. I rebooted again, added the rw init=/bin/bash was able to get in and reset my password. That worked, I was able to access with no problem. I was able to perform admin tasks, it would prompt for password and accept the password. I just went to edit a config file and all of a sudden it is no longer accepting my password again and (my son has been no where near it)?!!?
I am not even sure where to start troubleshooting this - I know I can reboot and reset the password again - but is there a way to figure out how this is happening.

I am unable to change session type when not requiring passord on login.
How requiring password was changed:
System/Administration/Users and Groups
Clicked on my User
Clicked "Change" next to "Password: Asked on login"
Checked the checkbox for "Don't ask for password on login"
OK'd, everything
Please try this yourself as it might be hard to understand. But the option to change session type (ie: Gnome failsafe instead of reguar Gnome) is only visable along side with the password field.
Is it possible to make the session type setting visable without requiering password on login?

I thought these were the same password?In-fact, they WERE the same password on the set-up I currently have.But now, weirdly, I can log in fine but I the exact same password is not using in order to perform admin tasks.I've tried a recovery mode, console, and then "password (username)" in order to reset the password.This does reset the password I need to use to log in, but the password still does not work for performing admin tasks

I needed to use Synaptic Package Manager to install an app, but the dialog box ("enter the Administrative Password") that pops up before you can use Synaptic doesn't recognize my password ("incorrect password). I tried typing it into a text editor and it's spelled right, caps lock not turned on or anything.
In Terminal, sudo recognizes it, and it is recognized when I log into Ubuntu. I'm the sole user, I have admin privileges, I've been doing admin things.
I just now did System > Administration > Users and Groups and got a dialog box saying
"Failed to contact configuration server; some possible causes are that you need to enable TCP/IP networking for ORBit, or you have stale NFS locks due to a system crash. See [URL] for information. (Details - 1: Server ping error: IDLmg.org/CORBA/COMM_FAILURE:1.0)"
Moving past that, I changed my user password, and Ubuntu authenticated it.
How do you launch Synaptic Package Manager from the command line?

I just bought this desktop from my friend and it runs win 7 and ubuntu 10.04. it worked very well the first two days until I changed the hostname of the system.
I did like: hostname myNewName
And everything worked fine. The problem now is when I start ubuntu and and reach username and password screen , I enter my password to login the screen becomes black and return me again to the screen where I put my password again. If I entered wrong password , the system message stating wrong password. On the other hand, when I try to run ubuntu from live-cd I can login easily and access my account.
My friend told me he removed Naultius package and reinstall it for some reason before he gave it to me. Note windows 7 is working properly.

I am an absolute Linux Beginner who is being required to do a bit of admin work because the boss just fired the old linux admin. Unfortunately, one of our employees cannot remember her password to her email account and as such I need to reset it on our linux server.What I want to check is that this email account is actually a linux user account and I simply will reset the password for it using the passwd command from the root login. Is that correct?

I work on a product that have to start automatically an application. Running Opensuse 11.2 So in the inittab I have : 1:2345:once:/root/Velox/VeloxBoot.sh 2:2345:respawn:/sbin/mingetty tty2
In the VeloxBoot.sh, if I don't press any key, my application starts after a timeout. If the user presses a key I want to have a login prompt. Unfortunately, if I start /bin/login, I have a prompt with login, but once I enter my login, it does not ask for a password and it says wrong password

I have a problem regarding the ubuntu enterprise cloud. I have installed CC,CLC,SC,NC and a client and logged into thje user interface using my browser for the first time with bith username and passwd as admin and downloaded the credentials.But now as I try to login with the same username and passwd, it says that its an invalid login. I understand we have to change the password on the first login but i don't remember doing the same.
I tried recover password option and gave the user name as admin and email address as my gmail id. It says that I have to follow the instructions sent to the mail, but there is no mail sent I have done it like 5 or 6 times with different mail ids

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.

I have setup a nis server and client. At first I didn't have a local user defined on the client. The client then used the user and passwords from NIS, so that was ok.
The problem then is, that when the server is down, I couldn't login to my client anymore. So I created a local user with the same name on the client but with a different password (after I shut the nis server down, if nis server was on, I couldn't create a local user with the same name). I then edited etc/nssswitch.conf as follows:
Code:
# (like no NIS server responding) then the search continues with the
# next entry.
#
# Legal entries are:
#
# compat Use compatibility setup
[Code].....
If NIS server is on: client has to login with the nis password If NIS server is down: client has to login with the local password (as fallback)
However the actual behaviour is that I can only login with the local password now. The NIS pasword doesn't seem to be used anymore.

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 use the following method for preventing the users from changing their passwords , is there any other method other than this ?
ls -l /usr/bin/passwd
-rwsr-xr-x 1 root root 37140 2010-01-26 12:09 /usr/bin/passwd
so we need to remove the suid for that command as follows :- chmod u-s /usr/bin/passwd now normal users won't be able to change their own passwords - and only the root user will be able to do it for them.

The other day I wanted to make a small change to my (user account) password, but I kept getting errors about the new password merely being the old with changed case, or just a cyclic shift etc.Security issues aside, is there any way I can override these checks so that I can make whatever minor changes I like to my password?

I am running ubuntu 10.10 desktop, i have my /home on a seperate partition and its encrypted. Today i was changing my password on the all the machines in my house ( netbook, desktop x2 and server all ubuntu) and i didnt want to go in the bedroom to change the password on my one desktop, (pure laziness) so i did it through ssh using
Code:
sudo passwd lynx
now when i restarted it later on i realized i cannot log on to the GUI. I get an error "Could not update ICEauthority file /home/lynx/.ICEauthority" and "There is a problem with the configuration server. (/usr/lib/libgconf2-4/gconf-sanity-check-2 exited with status 256)" also "Nautilus could not create the following required folders:/home/lynx/Desktop,/home/Lynx/.nautilus. Before running nautilus ,create the folders or set the permissions so that nautilus can create them".

I did these steps to change my username: I like to directly edit /etc/passwd and /etc/groups
First open a terminal, become root
Code:
sudo -i
Now:
Code:
usermod -d /home/new -m old
sed -i -e 's_old_new_g' /etc/passwd
sed -i -e 's_old_new_g' /etc/group<-
sed -i -e 's_old_new_g' /etc/shadow
My computer shut down after I did the second step and now my password isn't working! I cannot open my home folder or get back to root!

I have succesfully set up authentication manually in Ubuntu so users can log on with Windows Active Directory accounts and have their network drives mapped automatically using pam_mount.
Please note due to the setup I can't make any changes to the Windows 2k3 server.
If a user wants their password reset I can change it to a generic password. When they next log on to a Windows computer with the generic password it will automatically ask them to change it to something else.
Is there anyway to get this to work with Ubuntu 10.10? At the moment when logging onto Ubuntu with an account that is in this state the message Please change your password appears, it then proceds to log on without prompting to change the password and natually it won't map the drives etc.
