Ubuntu :: How Is Super User In Authentication Prompt Determined
May 3, 2010
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?
when I click on "Users and Groups" the dialogue box shows up, but I'm unable to make any changes because I'm not prompted for authentication (the "add", "delete" etc., buttons are grayed out). I'm using 10.10.
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
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 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.
I understand how to create a super user, but I do not understand how to create a password for that user. Can someone tell me how to please? Also when do I do this? Logged in as who?
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.
i trying to create file in /usr/local from below command"sudo df | grep /dev > dev_string.txt"First it asked for sudo password. I enterd sudo password. but I was not able to create the file dev_string.txt .Next time onwards it not asking sudo password also.the below execution flow
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.
I would like to be able to get squid or dansguardian to authenticate a user account against active directory so that a users browsing activities can be logged.
I can find lots a very useful info on how to set up ntlm_auth etc, but all of these methods produce a pop up window when the user launches the browser.
I'm posting this thread because I would like to be able to authenicate, but without a pop up window. Is there a way of automatically carrying out this authentication so that the user is unaware of it.
We've previously attempted authenticating against an NT4 PDC, but the users worked out that they could use any user account on the network, not just the user that was logged in which kinda defeated the whole idea of logging the users activity.
My current setup is:
Windows 2003 AD Windows XP Clients, soon to be converted to windows 7. Fedora 11 running squid and dansguardian.
My password doesn't work to enter super user mode in the terminal. this password works for all other administartive uses in and out of the terminal, just not for entering super user mode.
I am trying to be a super user in terminal but I can't. I am sure that I type the correct password, I check also the caps lock button and the language. Also I can't go to the yast. note that the root password is exactly the same as user password
Code: nobani@linux-m9c6:~> su Password: Permissions on the password database may be too restrictive. su: incorrect password nobani@linux-m9c6:~> I am using KDE 4.3.5 on openSUSE11.2
I have a program(that is written by me) which need super user permission to execute it. But I need to let the normal users to execute it without using 'sudo ./executable' and just './executable'. how i can set the program to execute by the normal users without using 'sudo' or password prompting.
Something has gone awry with my login. After the usual username/password prompt my laptop comes up with smart card authentication & I can't login. How do I get away from the graphical login so I can login & correct the problem?
My normal prompt looks like: username(at)ubuntu + current directory. (Odd format, it doesn't really look like that, but I was told I needed 15 posts to post an URL).Whenever I change user with "su username" (at least when changing from root to normal user), this prompt completely disappears. All it says on the left in front of the input "$". Also the history doesn't work, and the tab key doesn't complete anything, but rather acts as the normal tab in an editor. do I fix this? It is very annoying. Sorry for the stupid question, but I've searched around for an answer, finding none.
I have one Ubuntu 10.04 machine that is configured this way.I want GDM to prompt the user to enter their username via a text field, and then a password, instead of displaying a list of users to choose from.One way to configure GDM's appearance is to run the following from a terminal: gksudo -u gdm dbus-launch gnome-appearance-properties.If I remember correctly, there is a different dialog to run than "gnome-appearance- properties" that allows changing whether GDM prompts for a username or displays a list. But I do not know what it is.
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?
