General :: Crack The Windows Administrator Password (using The SAM File) Without Resetting It?
Jan 26, 2011
Is there a way to crack the windows Administrator password in Linux (using the SAM file) WITHOUT resetting it?
Ok so Ive already got Ubuntu 10.10 on a usb bootstick. Chntpw is installed as well. What I'm wondering is are there any programs to crack as in decrypt the SAM file and show the password but not erase it? Most Linux programs Ive come across don't do this. They just reset the password.

I have a win XP box and want to share files on this win XP box In Ubuntu 10.10 I previous used, I just connect the win XP sahred folder via file browser without any username and password. In my Debian Squeeze, when I connect to my win XPIt poped up a window and asked me the username and password. But I don't set any password in my win XP even my administrator account. How can I do to make my connecting to win XP smoothly like the Ubuntu does?

I'm trying to crack a password on a pdf document. I have been using pdfcrack from the repositories but when I run the command pdfcrack -f filename I get the error: Encryption not detected (is the document password protected?)
I get the same error if I add the -o or -u option. Does anybody know how to do this? Strangely, I can get into the file just by opening it in foxit in Windows, but when I save it elsewhere it is still password protected, so I need the real password. (Can't print to pdf in foxit in Windows)

I bought a ChemBook laptop which I have installed Ubuntu Linux on. It has an AMI BIOS. There is a password on the BIOS so I can not change its configuration. The laptop does not have a 3.5inch floppy. How do I reset or remove the BIOS password so I can access it and make my own changes and set up my own password?

I'm trying to install Skype on an Aspire One netbook, it shows the file in the downloads section but every time I click on it it asks for an administrator password. If I put this in the window closes and then comes up asking for it again a few seconds later, but if I put in the wrong password it gives me the option of changing it, but still won't allow me to run the programme

I'm using air-crack to crack into my network for fun. (It's WPA, NOT wep)
I've acquired a network handshake (I think, do I run
Code:
sudo airodump-ng --channel 11 --bssid 00:00:00:00:00:00 -w data mon0 and capture only four packets for WPA keys?)
After that, I need to run the command aircrack-ng -w wordlist capture_file (where wordlist is your dictionary file, and capture_file is a .cap file with a valid WPA handshake) My wordlist is in /home/steaksauce/Documents/Dictionaries/ and the particular file I want to use as a dictionary is lenth10.txt -- I downloaded a dictionary, and added my own passkey to it so I could have my fun

Owned linux laptop (running UBUNTU) for 1.5 yrs. Love it. No problems... until:
1. I changed my password, via System - Admin - User & Groups - Properties. (I just typed 2 characters on the end of the old User Password and the Confirmation password and OK'd it all.
2. Shut down laptop. Upon restarting it (only minutes later), neither the new pw or the old one worked.
3. Googled for help on another machine. Booted linux laptop up in recovery mode and used the passwd <?> command to reset pw (back to the original one!).
4. Shut down. Started laptop up again... forever more firefox runs like a dog. Normally (90% of the time) it times out before reaching a page, though it is trying to transfer the data.
Let's be clear about this. It was fine. The very next time I used firefox - minutes after the password debarcle, it was cac, and has remained cac ever since.
I've been whizzing around on firefox for over a year without any issues. There have been no changes to the router. My microsoft laptop has no issue with the internet so it cant be router or telco related. Though I did reset the router (power and phone line) just to be sure. It didn't help.
I clear the private data (Tools menu) in firefox regularly (daily-ish). That is the only housekeeping I do on this machine. (It only gets used for mail, internet and the odd simple OpenOffice document). There is stacks of space left (70 Gig). I'm not sure how to check memory.
Googled for help and tried some command to purge temp files. That didn't help.
I love my linux laptop, but currently I'm having to resort back to my windows one.

I've encrypted my root partition with LUKS and cannot remember my password. My main question is this: is it possible to extract the hash (or key; not sure on the correct terminology here) from the LUKS header and run it through a cracker? The hash type is SHA1 and I can remember the characters I used for the password, just not in the correct order (lots of special characters). That being said, given such a small charset, it should be crackable within a reasonable time, correct? Especially if I used a GPU accelerated cracker. What I don't know how to do is go about getting the hash from the LUKS header. Is any of this possible, or am I SOL? Of course, I have physical access to the system so I can boot it into any utilities I may need to.

I am new to using Ubuntu 10.10 that was installed by a friend of mine, but he didn't give me a password for administrator and now when I try to install VLC I am blocked by a password prompt. To make things worse I can't use F1 key, esc key, tab key, 1key (I copy and paste 1 from other pages when I need it). I am at a loss here and all I want is to change the administrator password without validating the current password first.

I have forgotten my user password....HOWEVER I remembered the root password and am able, (after much fumbling about)to get into the machine. Is there a way of resetting my password? It obviously will not let me do so on the password-reset-screen as it requires the old password....

I have been using Nautilus file browser in my fedora 11 desktop to browse Samba shares of our servers. Let me explain my problem.
We have two users test1 and test2 who can access Samba shares for downloading and uploading files.
test1 has read only access.
test2 has read/write access.
When I initially connected to the samba share through test1 user through Nautilus file browser I clicked on remember password.
But now when I try to access the share again, its not prompting for password. It is directly taking test1 user's password who doesn't have write access to share.
How to get the password window back to fill test2 username and password.?

There where some updates for 10.04.1 yesterday, after I installed them, a few hours later I restarted my machine as new headers and kernel files where downloaded.So this morning, when I come in, I wanted to check my software sources as I saw something a little odd yesterday.When I try to start that program; I am asked for my administrator password. Not the password I use for administrative tasks; which is what I am generally asked for.Anyone else seeing this? And if so, what happened. The admin account I have setup is My account, I am the only person on the machine. In the past I have entered my password and carried on; not this morning. Not sure what is happening; but I have not setup an actual admin account / password.

I had 9.04 64-bit with / and /home in separate partitions. Today I used 10.10 alternate install to install a command line system. Then installed gnome-core, synaptic, gparted, and a few other things. Now when I go to System > Administration > Synaptic Package Manager or to Gparted, I am asked for the "administrator password". I type in my password, but it is not accepted. However, from a terminal I can "sudo synaptic", give my password, and install whatever I want.

I love My linux OS, and I carry It with me all the time in USB. I used to be able to boot from USB in the University computers, but not any more. Now it required Admin password in order to boot from CD or USB. I tried The VMWare, but I didn't like it. Is there any way I can get around it.

We have a server for which the root password had been lost, and there were no other user accounts set up. Yesterday evening I attempted to reset the root password by booting from the install CD and using VI to clear the root password in the passwd and shadow files. I then rebooted, and the system has halted with an 'FSCK failed. Please repair manually and reboot' error, with a prompt to 'Enter root password' below. But of course the root password isn't known (I had expected it to blank after editing the passwd and shadow files, but it doesn't work), so I have no way of logging on.

I am tasked with resetting a user's password on a Windows Vista workstation. I am familiar with the chntpw utility, and I went through the motions of using Knoppix 5.1 as my live os, and downloading the aforementioned utility from the Debian website. Unfortunately, I ran into issues with glibc, and was unable to run the chntpw application. I went through the motions of booting with Knoppix 6.2, but I could not readily find the utilties that were available on the earlier version of the distribution.
Does anyone know of a latter day version of Knoppix, or any live distribution, that has utilities for mounting Windows partitions in read/write mode, and can utilize the chntpw utility to reset the password?

due to an exercise in Operating Systems I have to do the following: There are 6 users, user1, user2 ... user6 with home directories /users/user1 ... users/user6. User1 to user3 belong to group1, user4 to user6 belong to group2. The System Administrator wants to change the privilege* only to users 1, 2 and 3 to execute the file /bin/xxx. Which are the commands he has to type in order to achieve the previous?*I'm not sure if this is the right translation.What I have come till now is: Code: $ chgrp group1 <name_of_file> but it seems too simple to be right.

I installed Linux Mint 9 a couple of days ago (from a live usb) and my 'Account type' was set as 'Custom'.
I had to change the 'Account type' to 'Administrator' so I could edit the 'Network Manager' configuration (the 'Apply' button in Network Manager was disabled until I changed to Administrator).
Is it ok to leave it as 'Administrator' or should I change it to 'Desktop user' until I need to change system settings again?
