Ubuntu :: Setting Root Password For Maintenance Shell - Failed
Aug 10, 2010
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 want b able to recover or reset the password that i lost. I have ubunto installed with windows vista. I used the following link for guidance: [URL].. tried recovery mode in grub it always asks me the same thing:"Give root password for maintenance". I also tried to edit and boot the kernel unfortunately it did not work. So i never have a prompt, it still asks me for the password.

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...

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.

php. I am developing a web-interface for an application that sometimes needs root privs. Editting /etc/sudoers is not an option since the web interface needs to be portable to other users when they install my application. Is there any workaround ?PHP Code:

My Ubuntu Linux system was switched off at the mains without being properly shut down. When it was restarted again, the file system checks failed and I was presented with the maintenance console command prompt. How do I check what is wrong with the file system. Is there any sort of generic repair command that checks the disk and fixes errors?

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 notice when Linux boots in maintenance mode the filesystem is read-only.
Is there a way to change this, perhaps remounting as writable?
An example of this being a problem is that I was unable to open vi because there were too many session files....
Not to mention it would be nice to actually fix problems....
What are you meant to be able to do if you can't make any changes to the filesystem? What kind of maintenance can be expected?

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

I have a bit of a dilemma.
I'm using XFCE and it doesn't by default lock the screen before hibernating. I see this as a bit of a security risk, and as I can't hibernate while the screen is locked, I'm a bit lost as to how to achieve this.
I've begun editing /etc/acpi/hibernate.sh, here's what I have so far code...
If I run with sudo, the system hibernates, but gnome-screensaver will not fire. I can verify this by trying "sudo gnome-screensaver-command --lock". The screen goes black, but is not locked. The screen locks properly without sudo.
So the only solution I can see is to edit /etc/acpi/hibernate.sh in such a way that gnome-screensaver-command runs under the current user, and pm-hibernate is called as root.
Also, when I click the HIBERNATE button in XFCE, how does it call pm-hibernate under root without prompting me for a password? I normally wouldn't be interested in such things, but as it seems relevant to my problem I'm a little more eager to learn

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.

An old machine in our office, running Ubuntu 6.06 all of a sudden will not boot up. I get the following info during boot:
Uncompressing Linux... Ok Booting the kernel
mount: Mounting /root/sda1 /root failed: No such device
mount: Mounting /root/dev on /dev/.static/dev failed: No such file or directory
[code]....
I haven't changed anything on the system as far as I'm aware, and I ran some HD diagnostics and everything seems fine. however when I try to mount the drive with the following command:
sudo mount -t ext3 -o rw /dev/hda1 /mnt
I get the following error:
mount: wrong fs type, bad option, bad
superblock on /dev/sda1, missing code
page or helper program, or other error
In some cases useful info is found in
syslog - try dmesg | tail or so
I ran fdisk -l and it says the partition type is Linux. The output after running dmesg | tail :
[12207.483801] init_special_inode: bogus i_mode (101)
[12207.483809] EXT2-fs: corrupt root inode, run e2fsck
[12260.427078] init_special_inode: bogus i_mode (101)
[code]...
Update: After running e2fsck -p /dev/sda1, I get the following info:
/dev/sda1: clean, 142449 / 9584640 files, 5402711 / 19161520 blocks

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 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?

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 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 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:
[Code]...
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.

As I was researching on how to create a kiosk Ubuntu setting I came upon a suggestion to create the user with '/usr/bin/screen' shell option.Hope you all would forgive me for this noob question but what does this mean? I saw when I checked the Advance Settings Advance tab that there are a couple of possible options there, what do they mean and how will they affect the user profile I'm creating? I tried google for this and if my understanding is correct, these shells are suppose to be programmable and a scripting language for linux but I'm confused on what effect this has on the user profile I'm creating?One thing I notice though is that with the '/usr/bin/screen' option, the user account is refused of the Applications > Accessories > Terminal option.When I googled each one of the options I'm getting more confused as to the relevance of this to the user profile.

I'm running into a problem when I try to set a variable to an awk output in c-shell. Right now my command is Code: set STR_MSG_TYPE = `awk -F{ '/msg_type/ {print $2}' <filename> | tr -d }'/''*' ` I then run echo to see what the output is and it returns blank, however, when I run the same awk command from the command line, I get an actual output of "MT-715". Am I setting my variable incorrectly? I do something similar using the date command to set a STR_DATE variable earlier in the code and it works fine and I use the same syntax.
