I find out there are two ways to do that:
sudo passwd -l root
sudo usermod -p root
What are the different? I saw a kubuntu post said:
-l, --lock
Lock the named account. This option disables an account by changing the password to a value which matches no possible encrypted value. I enable and set a root password, I want to return to a "no possible encrypted value" just like the way it was.
It seem like unix abit annoying every time you log in you need to password can I disable it

View 4 Replies View RelatedI'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.

View 2 Replies View RelatedI 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?

View 3 Replies View RelatedAt 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.
View 4 Replies View RelatedI 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...
Example: In rc2.d I have S99test. In it: Code: #!/bin/sh mplayer -playlist "/music/Thom Yorke - The Eraser" Reboot; hear the loveliness; press pause (lirc setup)...still loveliness.
Login as root; "pkill mplay";hear nothing; "/etc/rc2.d/S99test"; more loveliness; press pause...silence! I know that i the former case, mplayer is assigned (for lack of a proper term) to a session, e.g. tty1. Not so in the latter. But why should a program like mplayer not receive (or ignore?) input from lircd, simply because it doesn't have a session? And how can I get mplayer (or any program run from boot scripts) to work with other programs (like lircd)?
Can a sudo user do everything what a root user can do? I read sometimes expert say "You should run it as root rather than sudo user".

View 4 Replies View RelatedI know, I know, its a security feature. That doesn't make it any less annoying. I find the constant asking for my password to be every bit as irritating as Windows's UAC. When I want to use the terminal, or when I want to download something, I don't want to have to enter my password every time. I don't care that someone could theoretically do something to my computer in some way. I managed to stay out of harms way in windows with UAC off, I'm sure I can do it in ubuntu without the constant nagging of the password prompts. Its annoying and I am tired of dealing with it. Anyone know how to turn it off? I am really not looking for reasons to leave it on. Its the same with UAC: Yeah, it can keep you out of trouble. No, I don't want it on.
