Software :: Cannot Authenticate Root Password / Make It Possible?
Jul 9, 2011
Lots of password threads, but I didn't see this.
Installing Debian 6.0.2.1 amd64 on a Dell Optiplex 740.
The default install (simple graphical) works OK. But when I install "graphical expert", the same root password seems to be OK during the install, but doesn't work when the system comes up.
A. I have used a very short pw. It worked before.
B. The root pw is the same as the user pw. It worked before.
I am installing from CD and from DVD, both downloaded and burned as iso. In both cases, I asked for "graphical desktop" and "standard utilities", no servers, no laptop, no SQL.
I have fedora linux as an operating system on my laptop but each time I try to install a new program it prompts for an authenticate root password of which I have no idea. I wanted to install windows xp on it but each time I do so it prompts"se-linux denial" on the base that the source is not trusted as i didnt authenticate it.
When I run sudo as a normal unprivileged user, it asks for my password, not the root password. That's often convenient, but it reduces the amount of information someone would have to have in order to run commands as root. So how can I make sudo ask for the root password instead of the invoking user's password? I know it'd be done with a line in /etc/sudoers, but I can never seem to properly parse the BNF grammar in the man page to figure out exactly what to write.
Is it possible to make root password visible as asterisk(or any other character) on using sudo command??urrently,it does not display anything on monitor,thus,making it difficult to count the number of keystrokes pressed...
I try to install my printer again after reinstall ubuntu 9.04. ("downgraded from 9.10"). Instead of asking for the local-user-login password, as it does for other system changes, it asks for a root password that I never had. What happened? How can I set this right?I made a printscreen.
I tried to change my password through the Users and Groups dialogue, and now neither the old one nor the new one work. I tried to do it once, and it didn't do anything (the password was still my old password), then the second time I did it, when I went to save the configuration it wouldn't take my new password or my old one. Now I can't authenticate for anything.
A wicked backdoor I've noticed is that going into recovery mode offers you a root console without authentication. (Awesome, Linux, secure as all ****, seriously.) Is there any way to use this to set my user password without needing to authenticate?
Today I've found out that I cannot authenticate and use my ubuntu 10.10 partition as it doesn't recognize my password! The password is correct, I also tried to change the username in "root" but nothing changes. When I write it, it shows for some istants a black screen with words in it (so quickly that it's not easy to read) and then it shows me again the form to access.
i recently switched to ubuntu 9.10 from win vista, i am having a problem... in ubuntu when ever i do any changes it asks me for my password, i know that its for my own PC's securiety but now i am really annoyed with this.
I may be a beginner to Ubuntu 10.10, but I'm fairly certain that this is weird: I have had no trouble logging into my Ubuntu 10.10 netbook until this morning. Now I am unable to get past the login screen. It says that there is an Authentication Failure, which is bogus. Not only should the password work, but it does in the Terminal. I am able to login to the terminal and gain root access.
I can even change my unix password, but no matter what I try I can't get to my desktop. I did run into a major issue with a frozen program. Rather than reboot, I tried to close it using the kill command. What ended up happening was that all that remained was my wallpaper, probably a bad move on my part, but I'm a rookie. I think I killed all running applications. This happened last night... so probably related.
I am wondering how websites like banks are able to determine if you have previously used a certain computer to access the website, even if your router's IP address may have changed and your system's cookies have been cleared. I have users that need to access our HTTP intranet from outside locations. Those locations will have dynamic IP addresses most of the time, so I can't just "allow from [ip]" in my Apache proxy configuration. Originally we considered a VPN, but determined that a VPN will be overkill to access just an internal website, since we do not want external users to have permission to the rest of the network, only the website.I currently have it working over HTTPS with basic authentication against an internal LDAP server, but I want a little more security for such an important website.

fedora 10 and im trying to set up some user accounts on a computer. My current problem is that we set up 2 root accounts and we need both to be able to authenticate. So far this works on the command line but whenever i'm on the GUI it seems that it only allows root to give its password for things. How do i enable the second account to do that as well.as a note, i am doing this for someone else so i have little to no control how this is set up, so please, i am not looking for reasons why this is not a good idea i would just like to figure this out
I setup my evolution to get this forums news. (eg. threads and posts). However, I can't get them because it give me this: I keep entering my forum password over and over again but I can't authenticate :S And you might also need to check these: [URL]
I was having trouble with pulse audio and completely obliterated pulse audio from my machine in order to prepare for a reinstall of pulse audio. this also uninstalled a few other packages that I needed to enter gnome or kde. when I try to login via gdm(?) my password will not authenticate (when I enter via xterm or tty the password is accepted). how can install packages off a live usb drive from Terminal. how to access a wifi network under terminal to use apt-get.
I am trying to use a guest account in Ubuntu 10.10 however I am unable to stop the guest account from authenticating as a superuser and gaining root permissions dispite removing all permissions from the user-group control panel. The new guest account I created is not part of the admin group. However, with my new guest account I am unable to start a guest session from the panel, AND if I use the guest session from the panel I dont have the problem with the guest session being able to authenticate. How do I prevent super user authentication from an account in this situation? It seems that any account can authenticate and my /etc/sudoers file looks like this:
# /etc/sudoers # # This file MUST be edited with the 'visudo' command as root. # # See the man page for details on how to write a sudoers file. #
Defaults env_reset # Host alias specification # User alias specification # Cmnd alias specification # User privilege specification root ALL=(ALL) ALL
# Allow members of group sudo to execute any command # (Note that later entries override this, so you might need to move # it further down) %sudo ALL=(ALL) ALL # #includedir /etc/sudoers.d # Members of the admin group may gain root privileges %admin ALL=(ALL) ALL
Well this one is driving me nuts. I've been searching through the forums for a while and it seems that a number of folks have similar issues but the solutions used don't look like they apply to me. so without further ado here are the outputs typically requested:lspci

Have dual boot winXP, FC6 computer. Clobbered something so FC6 does not boot. Am trying Ubuntu 9.10 CD; tried first to run from CD- but it asks for username and password, will not accept blanks nor my winxp values- keeps 'failing to authenticate'. So I did an install in new partition beyond linux fc6. It finally lets me log in, giving a small text window. How to get to desktop, and is there a way to get to my old home files in linux fc6 in native linux partition?
I have a Windows domain with a proxy. I have an account that can use the proxy and the URL that points to the proxy.pac file. this might seem a stupid question but can anyone tell me how do I enter the username and password for my test Windows account so that Debian can authenticate it?
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 m Trying to get vsftpd usergroups to work i accidentally moved a file called passwd from /etc/vsftpd/ to /etc/, resulting in my root access is destroyed! how to restore the passwd file so i can keep working, or do i have to re-install the entire box?
I'm really new to Linux so this will probably sound like a pretty naive question to most users, but how do you change the root password?To install Java, I have to type # su into Terminal,which then asks for the password.What's weird is that when I start typing a password, no characters show up. I don't know if this is supposed to happen or not.I've found a bunch of different sites on the Internet that explain how to change the root password, but none of them seem to work for my specific work station.
I've got Ubuntu 9.10 64 bit. In the GRUB boot menu, I can choose to boot normal or in recovery mode (I'm led to believe older versions don't have this option).I've tried typing # sudo passwrd into Terminal, but I already have a root password set up apparently, so I can't change it there.
I no longer have access to my root desktop. On a session I attempted to change the root username but i apparently assigned it a wrong directory that does not exist. When I rebooted with my new root username, i was instead recognised as a simple user (no root privileges). I tried the console to change to "old" root but root password is not accepted and there is no way to access to sudoer files. it seems that inserting a new username requires root privileges and i am back to square one. Simply logging with old root username and password after restart gives me a blank screen with nothing on it and cannot even reboot.
i used opensuse 11.1 ...there is option for root user to create password for root...but for ubuntu i did not find anything like that...so how can i create root password....or how can i use root
I was trying to edit a file requiring root permissions, so I used sudo. I typed the root password and it failed. This happened three times, and the process was ended. I then logged in as root (su) and was able to navigate to the file and make changes as root. Am I missing something? How would I edit the sudoers file such that this password would work? Or is there another way to log in to the sudo group to make these changes? How do I set sudo passwords?
At the RHEL prompt, I entered the standard user's username/password combo. Linux displays a message box stating:"Your account has expired; please contact your system administrator."Next, I entered "root" in the username field and entered the root password (which expired also--keep in mind that passwords are set to expire after x days). Linux displays a message box stating:"You are required to change your password immediately (password aged)."When prompted to "Enter current UNIX password", I entered the new password (was that the right thing to do?); Linux displays a message box stating:"The change of the authentication token failed. Please try again later or contact the system administrator."I rebooted the system and got into command line mode; somehow I logged in as "root" (don't know exactly how, but needed to change the password there). At the "#" prompt, I type "passwd root"; Linux displays the message "Changing password for user root", followed by the message "passwd: Authentication information cannot be recovered.
I edited fstab to automatically mount my windows data partition on boot, but I screwed it up by not specifying the file system type, however that is not the problem, I was able to fix that easily. The problem was that when it failed to mount the partition, Debian automatically entered root and I guess that is to be expected in order for me to fix it, but I never configured a root password and it just gave me full root access without asking any password, not even my user password. I though that was strange so I set the root password and sure thing it asked me for the root password this time without automatically logging into root....
I then tried to lock the root account to see if it will ask me for a password or not, it did but of course I wasn't able to login as root because it was locked now and I was left with no way to access the system. I had to fix fstab from a live cd so that I can login normally as the user....
I didn't know what to search for or if that is the expected behavior if you don't set root password during installation, but it just seemed a bit strange to automatically enter root when you specifically disable root login during installation...
A friend of mine has told me to set a root password and use root (f.e. switching to su in terminal and work with root rights instead).Is there any way to unset the root password? I know how to use sudo now.
