Debian :: Root Login Without Setting Root Password
May 14, 2015
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...

Suddenly Debian started rejecting my user pw and I have to login as root. Perhaps this is a coincidence, but this started when I re-booted after adding Russian keyboard layout in etc/default/keyboard. The Russian keyboard added successfully.
Being logged in as root, renewed the pw of my user account (actually assigned the same as wes previously), got confirmation the the pw has been changed. Reloaded. Yet it keeps complaining that the pw is wrong.

Having installed Debian 7 on an old machine from a Liinux Format Magazine DVD I was unable to log in as a specific user. I can login as root and use useradd etc but when I logout of root I still cannot login as a user and nor will the machine accept my root password. I have to shutdown and reboot to get back into root. I'm using O'Reilly's Linux Pocket Guide from 2004 for the commands. Could it be that things have changed?

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?

When I installed the OS, I wasn't prompted to set the root password. Is this a bug, or did my install hose up?

Using 11.04, and just installed mysql 5.1.54 using synaptic
I was following the instructions here and the installation when fine,
except that I never got a screen to set the root password.
When I try to set the password using these instructions, following either
"If you have never set a root password for MySQL" $ mysqladmin -u root password NEWPASSWORD
OR, since the first method failed me, then: "However, if you want to change (or update) a root password, then you need to use following command" $ mysqladmin -u root -p'oldpassword' password newpass
Either way, it fails. Question:
1) why am I not being prompted to set a root password during installation?
2) what can I do now to fix this??
I am trying to learn Mysql, so don't presume I know anything about command syntax (cookbook instructions) For example, the first command above,I tried with with NEWPASSWORD in quotes, and then without. Likewise for the second command.

I'd like to keep root pw==sudo pw==user pw on a box with Code: $ lsb_release -ds Ubuntu 9.10 $ uname -rv 2.6.31-22-generic #61-Ubuntu SMP Wed Jul 28 02:02:56 UTC 2010 Just now it hung going to sleep, so I shutdown via BRS. On cold boot, HD mount failed and I got the prompt to hit Esc to goto maintenance shell. I did that, got the prompt for the root password, and entered my sudo.
That failed! though it has worked before ... but I changed my user password on that box recently, and I'm pretty sure I haven't needed to fsck between then and now. I'm wondering: What do I need to do to set my root pw? I was able to C-d out of the shell, and karmic took care of itself, but I'd prefer not to rely on that. Is there a way to make my root pw always equal my user pw? If so, is that a Very Bad Idea?

I got this from a website (cant remember URL).
Be warned if someone actually does manage to login as root on your computer or server.
Edit .bash_profile for root. How do I do this?
Code:
echo 'ALERT - Root Shell Access on:' `date` `who` | mail -s "Alert: Root Access from `who | awk '{print $6}'`" your@email.com
Replace your@email.com with your own email. Save the file and exit.

When I try to do

sudo su root
The login is successful without prompting a password. This is dangerous. How am I going to avoid/disable this?

Found a major security hole in one of my more crucial linux servers today. (Only locally) I can use the user name "root" and any string for the password. So I can literally type "poop" as the password and the server lets me in. I know how to set root password settings for SSH and sudo, but where are settings located for local access that would allow something like this?

Can't seem to do it, wondering if anyone knows how? Normally there's something in sshd_config that can be switched to true or yes to allow root login but I can't see it in fedora 12.I can login via root at a terminal no problem, just not via ssh, I get access denied every time. Also, I need to login using password authentication.I've done: 227169 but that's just for GUI which I don't really need since I rarely ever log into the GUI.I have also searched through here and mostly only found info such as above, how to enable root login for GUI, or billions of posts about how logingin as root is bad but I cannotswer to my question.DISCLAIMER: Please do not reply to this thread if all you can contribute is the question of why I need root or to put some message telling me I can do everything using su, etc, etc. Please only contribute if you can answer my question. A: My machine and a valid quesiton. B: Spirit of Linux is open, not restrictive

I am new to ubuntu and I've installed it but I didn't use it too much. Now I was trying to login into ubuntu but I forgot the root password. Can I login into ubuntu or change the root password. I didn't make any other user than the installation were asking me. If I try to reinstall the ubuntu, the setup will help me to choose the same partition (to overwrite on the previous ubuntu)?

I'm trying to figure out why my industrial appliance (x86, running kernel 2.6.21.7 and OpenSSH_4.3p2 / OpenSSL 0.9.7m) accepts ssh connections without asking for a password (even for root)!When I log on to the local console as root I have to enter a password but strangely this prompt won't appear using a ssh connection (although I'm not using any client certificates).Of course that not acceptable but I just can't find the related configuration entry to disable this "password-less" authentification.Is this related to the sshd or has it something to do with the PAM module?
- Update ->
While looking at /var/log/secure, I've found the following lines:
Jul 18 16:55:07 localhost sshd[5712]: Accepted none for root from XXX port 6393 ssh2

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 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?

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.

I found this on Bee's website. For more info on this exploit there are links there:[URl]..All you have to do in Fedora 13 is enter the following lines in a shell as normal user:

I don't think this can be considered solely an "upstream" problem, because I first tried it in Arch using the same version of glibc, and the final command causes both gnome-terminal and xterm windows to disappear.

I am trying to log into a server with a particular account. Let's say I don't know the password for that account. Can I do this using ssh? I am wondering if it is possible to do it in one command, instead of logging in as root and running su.
