Ubuntu :: Change Root Password - Typing A Password, No Characters Show Up?
Mar 9, 2010
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.
hello i am trying to change my password, but when i type in the new password i get this:"The password is longer than 8 characters. On some systems, this can cause problems. You can truncate the password to 8 characters, or leave it as it is."my question is what kind of problem could i get and how can i change so i have to log in every time i start the computer?
I'm trying to run a script that needs root privileges without typing in the password. I want to copy a file from my documents folder into /etc/X11 to overwrite my xorg.conf. I do this because I will have my computer switch from my monitors to my TV when I watch a movie. But I'd like to be able to make it a clickable icon so I don't have to type in cp /... /etc/...
Then I read a lot of places that said to add this to the sudoers file (sudo visudo)
Code:
nertskull ALL = NOPASSWD: /home/nertskull/Documents/switch_TV.sh
I've done all that, and I still get asked for my password when I run that file.
nertskull ALL = ... %nertskull ALL = ... %users ALL = ... %admin ALL = ...
I'm sure it's something simple I'm overlooking, but I've read 5 different threads on this, and I can't find anything they did that I'm not doing. Also, here is my sudoers file, because I know location within the file matters. But what I read said I should be putting my stuff at the end.
Code:
# /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.
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 got during my last year of high school, and I recently installed Fedora 11. During the installation, I misunderstood one of the questions, and set my root password as what I wanted my account password. I want to go in and change it, because it's pretty easy to figure out and has me feeling really vulnerable, but it won't let me. I went to System-Administration-Root Password, entered my password, and put in a new one, but it won't let me click Change Root Password. The button is faded out and unclickable. I've tried several different passwords, and triple-checked each to make sure I typed it in correctly, but it won't work.
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've been using Ubuntu for like a year now. Whenever I want root privileges I just type sudo and enter my User password. I wanna know if there's a way to change this, in a way that My User password is: "ABC" and the password needed to have root privileges is: "ABC123". I have no problem using the terminal, I actually prefer it to any GUI, it just seems easier to me.

To comply with standards I need to change the root pw every so often. However, I really don't have a need to know the root password; as the only thing using root, is for ssh authenticating via ssh keys. What I want to do is automate the root password change monthly via a cron job, to a random value. Is there a way to do this without knowing the previous password?
I work on a product that have to start automatically an application. Running Opensuse 11.2 So in the inittab I have : 1:2345:once:/root/Velox/VeloxBoot.sh 2:2345:respawn:/sbin/mingetty tty2
In the VeloxBoot.sh, if I don't press any key, my application starts after a timeout. If the user presses a key I want to have a login prompt. Unfortunately, if I start /bin/login, I have a prompt with login, but once I enter my login, it does not ask for a password and it says wrong password
