Ubuntu :: Unable To Log In As A Super User?
Apr 22, 2010
Recently I installed Ubuntu using WUBI. During installation it asked for a user name and password which I filled in. That user name and password are the same that I now use to log into ubuntu. But now I am unable to log into super user using the terminal. When I try to log in to the super user account it says that the password is wrong. During the whole installation process only once did wubi ask me to enter password and I am using the same password. My windows user name and password are the same as what I entered during installation.

I have a question that i want to make a normal user to execute the commands which the root user is able to execute, say if i have a user named siru and when i logged in using siru i cannot run commands like tracert,nmap@loccalhost and all but i can run when i have logged into root account so my question is how to make siru to run the command tracert,nmap@localhost.I have even edited the .bash_profile of siru's home directory from
# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
[code]...

I have been trying to run the program unrevoked so that I can flash and root my phone. I want to do this on Linux, but this requires me to run the program as root and I don't know how to do this. I looked it up online and it told me to simply type sudo reflash or gksudo reflash and I tried both, sudo says it can't find the program and gksudo does something then nothing appears to happen.

How is the super user determined for the dialog box that pops up when trying to perform administrative tasks, "An application is attempting to perform an action that requires privileges. Authentication as the super user is required to perform this action."? Does it always ask for the password of the default user created during the OS install, or should it prompt for the current user's password if that person is an administrator?I use likewise-open for windows domain authentication, so I typically log in as a windows user that likewise-open has added to the list of users on this system. I have given this user sudo access and added the user to all the same groups as the default user, yet whenever I perform an administrative task in gnome I am prompted for the password of the default user. Is this normal? It seems like the behavior would be to ask for the current user's password if that user is an administrator, and if so what determines that the current user is an administrator?

I'm running Ubuntu 10.04 minimal with Openbox; far from a standard install but nearly everything works the way it should.
The problem appears quite simple:
Firefox does not recognise installed plugins (i.e, Flash) when running as the standard user; if I run the command 'sudo firefox' however, Firefox loads in plugins just as it should.
I've checked about:plugins in both instances and this has confirmed what is stated above. The list is populated when running as the super user, and empty when running as standard.

I am trying to set up samba server on my box, and the easiest way seems to be to use the kde4 samba setting dialog. I need to run it as super user though. I tried
su -
systemsettings
but the window doesn't seem to appear on the screen.

I have a very stupid case, I have to use a domain user to install one software in RHL4.8, but this software need a super-user permission but not root.
So I need a domain user who has super-user permission.
Not use su, sudo.
If I use su or sudo ,the software will be installed under root. The requirement is the software must be installed under a domain user.
How can I do?

After updating my system yesterday my laptop will no longer connect to my wifi connection, in fact the network manager doesn't appear on the screen. I cant access super user even with the correct password. Some programs fail to load e.g. hardware drivers.I'm online now using my ethernet cable. I cant update grub due to errors in etc/grub.d/README.I'm logged in as root now instead of my own user account.

After a week of working with Debian, I decided to install the KDE3 version straight from an NetInstall CD. This fixed some issues for me as well as made networking and folder sharring a snap! But now its time to add all the extra packages I need.
Here's the problem: Using any kind of Package Manager yields the same results:
E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (var/lib/dpkg/), in another process using it?
RESULT=100
I've tried apt-get from root command line and the KPackage Manager that comes with KDE3 with same results. I have only one user that was created during Debian install. I'm having some other problems, from what I've seen on the net, they all seem to point to not having proper Super User access (I'm guessing here). What could cause this error? AND/OR How do I make sure I have top level access to the configure the system? (I tried logging in as "root", but the login errored out saying that this was not allowed).

how to use the <Super>ButtonX (<Super>Button1 for example for the enabled Compiz Screenshot plugin)? I also notice there is configurable buttons 1 throught 20 under the various options. At first I thought the ButtonX was a mouse button. Maybe it is with some anticipation of there being eventually being a possible 20 buttons on the mouse. I know the Super key is the Key with the Windows logo on it. But I don't know what to do to get the needed Super Key / Button combination. After having enabled Compiz's Screenshot plugin by its default, I don't get an image after hitting any of the Super key and mouse button combinations. I'm running Ubuntu 11.04.

Code:
nobani@linux-m9c6:~> su
Password:
Permissions on the password database may be too restrictive.
su: incorrect password

I dismayed to find that Ubuntu Netbook Remix 10.10 no longer allows a user to assign the Super key (Windows key/Mod4 key) to keyboard shortcuts.
There seem to have been a number of unfavourable changes to UNR 10.10, but this is the worst. Super key functioning is essential for launching applications for many users.
I am no longer able to use UNR and I must uninstall it today. I think this is a shame, because I have always wanted to support it.

When formatting an ext3 partition, the default -m option is 5 (5%). Two things I always wanted to know but were afraid to ask:
1) Isn't 5% way too much for the size of most hard disks nowadays?
2) Is that number or anything greater than 0 really necessary in ALL file systems? For example, is it necessary in a /home partition or any partition that contains no OS, just storage data?

I was apparently invaded this morning via my private FTP server. The invader logged in with my user name and apparently knew the password for the account,The system is Hardy LTS 8.04.4, fully updated. I have backups that pre-date the intrusion, stored on another system, so am not totally averse to reformatting and reloading everything -- although I'd like to avoid it if possible.The "passwords.txt" file contains only a few passwords for online forums, including this one; it does not include anything critical such as banking information. I'm most concerned about the implications of the ssh config data...

After my last upgrade from 10.? to 10? my users' (kids) were unable to login. I tried to fix it and could not find anything wrong. Now I have upgraded to 11.? and the problem persists. The users could still login by selecting an older version at the prompt during boot up.
I deleted there account and reinstall the user and still they could not login. I added a completely new test user and could not log that one in either. The system excepts the password, waits a several seconds, then the mouse curser changes to the spinning circle. The hard drive lights flash for many seconds then eventually the hard drive stops flashing. I have let it sit a long time and it never continues. Tonight I came home tried to login and it is doing the same thing to me tonight. I ran fix packages, fix grub and everything else I could think of and could not log in.
Finally I logged in to the oldest version on there and it let me in.? The screens are all the same but the desk top is entirely different? I have never seen one like this. I think its like the new version of fire fox, with every thing moved around. Icons down the side. Menu's hidden at the top? I can probably get used to that but I need to able to login, and my user's to login?

Add some pictures inside your Pictures home folder (~/Pictures). Summon Gnome-DO by hitting [Super]and[Space] Type "slideshow", hit [TAB] and select the 'Pictures' folder or another user-defined folder where pictures are stored and finally hit [ENTER] I've Googled the topic (super key) but all I've found is "what," not "where."

I have dual boot (wubi) Windows XP. It was working smooth until I upgrade ubuntu 9.10. At the boot screen I choose Ubuntu, then it ask me wich version, then it freeze. I tried the recovery version, but then it ask me for a user ID login and password. At this point I'm able to enter the user , but it don't type anything on the password and keep asking me to enter the user id and password again, and again.

I have a problem to mount my cdrom as a regular user. After inserting a cd, I receive this error message:"Error mounting: mount exited with exit code 1: helper failed with:mount: must be superuser to use mount" After mounting the cdrom as superuser with "sudo mount /media/cdrom".I can access the cd also as regular user. This behavior is inconvenient and I would like to be able to mount the cdrom as user.Honestly, I do not have the experience to tell if this should be fine or not. Do you have any advice for me to fix this problem? I am running Ubuntu 9.10 with a 2.6.32-02063209-generic kernel.
