Ubuntu Security :: Erase A Partition Without Entering A Password?
Jan 2, 2010
I've installed Karmic after having used Jaunty in the past and it's working great, but I have a couple of security questions...
I opened the Disc Utility (Palimpsest) under System>Administration and was amazed that it looks like it will let me delete partitions on my hard drive, and without even asking for a password. This seems like an enormous security oversight, what am I missing here? Is there a bug filed for this?
Also related, why does Ubuntu allow a user to disable startup applications without requiring a password?

I am liking Opensuse, but have a problem when using my NFTS partitions (dual boot so docs on this partition). I always have to enter a password which annoys me to no end. Most distributions do this, in fact only for Mandriva have I been able to find out how to do this without a password. Is it possible with Opensuse?

I'm using Ubuntu 10.04LTS. I'm trying to configure my chat accounts. But after entering username and password, it is asking "Enter password to unlock your login keyring". I have entered my login password. But it is saying that "The password you use to log in to your computer no longer matches that of your login keyring."

Whenever I am prompted to enter the root password, typical example would be in 'Power Management' clicking the button 'Make Default', pressing ENTER or clicking AUTHENTICATE doesn't close the box. To get passed this I have to press ALT+F4 and it continues which I'm assuming still does authenticate.

When I use rar e to extract a rar file, the request for entry of the password always says password will not be echoed. For longer passwords, this is difficult, since a single mistyped key will result in an error.
Does anyone know how I can use the rar command to extract and have the password echoed (appear on the screen as I type it)?

I have a dual boot machine and recently did a fresh install of 10.4. It no longer asks for a password to access the Windows partition and I full access to it. This seems insecure to me and was wondering if someone else came across this. I thought I saw this topic discussed before but I can not seem to find it now. Is this a bug or a new unpleasant feature?I don't think it makes a difference but I do have a separate encrypted home partition on this fresh install. I have also done two fresh installs. (Well three...once testing out KDE but didn't try the Win partition. )

Any idea how to log a user in without a password in GDM? I've found this archived thread but it doesn't appear to do anything when I tried what it says: [URL] I'm not looking for auto-login. I'd simply like one user to be able to click on his name and it will log in without prompting for a password.

How can I change or erase windows XP password from Ubuntu Live (11.04) booted on the PC in question? I reckon it should be possible, at least it is possible to do so to another Ubuntu installation, but I never knew how to do it to XP.

I'm a newbie running Ubuntu 9.10. I have two users (wife and me), and each user's screensaver is set to lock so that on wakeup, we get to choose which user's desktop to go to. However, Ubuntu requires a password, so this is pretty tedious.I'd like to switch users without entering any password. I know about this trick that works for the boot login, but it doesn't deal with multiple users.Is it possible to set empty passwords for users in Ubuntu, or skip the password in other ways?(I'm expecting real Linux users to suggest that passwordless users must not get any rights and there be an admin user with a strong password.

Is it possible to switch users in Debian without entering a password, as in Ubuntu Maverick? I already tried adding a nopasswdlogin group but it did not work, even though the "don't ask for password on login" entry in the login manager is no longer greyed out. Replacing gdm3 with gdm also did not work.

How to allow a user to login without entering a password?
If my question sounds wierd then check out m-net at www.arbornet.org/m-net.php and see how it works.
Telnet / SSH to m-net.arbornet.org and type in newuser and it won't prompt for a password.

I just installed CentOS 5.4 (x86_64) and I encrypted my /home /var /tmp and /mnt/Storage partitions, along with my swap partition. My only complaint is that when I boot, I have to enter my password 4 times, and I did not pick a short password. The password is the same for all 4 partitions. Is there anyway I can set things up so I can just type my password once? Once I get everything set up, I won't be booting that often, but right now it is a PIA.

I have an unreasonably long time to wait from log in, to when my desktop is ready, it takes 40 seconds from hitting enter to seeing my files on the desktop, and about another 15 seconds from then to hearing the opening jingle. It used not to be this way, before it took less than 10 seconds, but about 4 days ago this time shot up suddenly, is there some way to diagnose whats causing this delay?

I tried installing lubuntu 'over' ubuntu, but am now locked out. Basically, the login screen loads, I've tried entering my username and password, but it doesn't work. I'm not really sure of my username as Ubuntu would automatically fill it in for me. But lubuntu isn't auto-loading my username, so I've been trying to enter all types of variations. I am 100% of my password though
I tried getting help at lubuntu's chat, but that's been kind of hard since there aren't that many people responding. The lubuntu people had me go into recovery mode (2.6.38-8 recovery) and so that would go smoothly. But when the screen of the options of resume, clean, dpkg, failsafex, etc, I cannot move the selector down. So basically, the orange selector is stuck at resume. Whenever I press the down key, the computer runs some lines, and I cannot go back to the list of options. The list is still visible, but can't select any of the options.
If I press the 'end' button, that executes something (probably the last option in the list), and I shut down the pc when it did that. The other arrow keys do nothing. The tab button manages to move the selector from the list to 'Ok' and 'Cancel.' But I cannot move the selector down.. TL;DR: I need to either get into recovery mode, or find a way to get my exact username lubuntu thinks it is.

I found a way some times ago to mount a truecrypt volume when opening the session by insertion of the login password in the mounting script instead of putting it in clear in the script. I don't remember to command to read/transfer the password.

Well, first off I'd like to say that I am much happier with the wireless on Ubuntu 10.04 than I was on 8.10 (the last time I tried Ubuntu). However, there is a small annoyance I'd like to fix: every time I log in, I get a prompt saying that an application (the wireless network manager) is requesting the password for such-and-such keyring. I have to enter the password before I can connect to my network. Is there a way to get around this somehow so that I don't have to enter the keyring password for this keyring (the "default" keyring) every time I log in?

I am looking for a PDF editor for Ubuntu that has the ability to erase all metadata from a document. I want to do this so that even if the PDF file is posted publicly, I would be at no risk.
I know Adobe Acrobat can do this completely and well, but it isn't free. Does anybody know what else might be able to do this job? I need a utility that can erase everything, including deleted/cropped content.

I am running a dual boot system under ubuntu and Vista on my laptop. Many months ago the Windows partition crashed completely so half of my computer is practically dead. I would like to erase Vista and integrate their partition in the Ubuntu one. The best case scenario would be if I could just merge the two partitions into one and just have one large Ubuntu partition. If this is not possible, could I create a second hard drive within the linux partition?
I would just erase everything and reformat the whole hard disk to run under Ubuntu, but unfortunately I need my computer on a daily basis for work and I have installed so many programs that it would be really painstaking to reinstall them all from scratch... I am not so skilled with informatics, and I'm really scared of losing data, so if anyone could spend some time for a step-by-step solution description I'd be really grateful! Or, of course, eventually write a link where the problem is treated. I am running under Ubuntu 10.04 Lucid Lynx.

I cannot sudo nor log into a second ssh session on my Ubuntu 10.10 server edition headless setup. Entering an incorrect password works as expected but the correct password gives errors, and on the second attempt a segfault. I recently changed my password as the old one was about to expire, that was 3 days ago, I can't find evidence that I have sudo'ed or logged in a second session since, I have been logged into it via ssh throughout all of it and I am still currently logged in. What should I do to correct this problem? I'm worried that by turning it off I will lose all access. Is the only option using a live cd to change the password?
