my dvd-rw was not working. but i had to install linux. so i installed ubuntu from the iso using demons tool. But when i am opening the terminal to create an user,it's prompting that only root have the permission to create an user. i am trying to use "su" command but it's showing that authentication failed. How can i become the root?
View 4 Replieswhile using my pen-drive in fedora 14, a small dialog box appeared and before I could read it,it disappeared. It worked normally till I turned the computer down. Next time I used Windows XP. There were no files in the pen-drive but it still showed 5 GB used ( the same amount of data was there previously ). I restarted and switched to Linux. All my data was in a single folder named 'Found.000' . It showed nearly 400 objects , renamed as 'file0001.CHK'. They were all mine, merged in a single folder. I am helpless because I can not delete them (as I need them). I can get administrative privileges.

I often get responses from people who first say: "Are you sure? You want your network to be exposed to the outside world?" I am not experimenting on a Production Server of NASA or any Security Concern Department. Friends, there is no harm in experimenting on your personal computer or on a test computer which is isolated from the production environment. Look at hackers! What do they do? If they don't know how security is breached then how would they come up with security measures?
If my question reads... "How to let any user perform Administrative Tasks on a Linux System irrespective of his/her privileges on that particular system?" then I would not get the right answers in the first place. They will say... "You are letting everyone destroy your system... are you sure you want to do that?" My question is: Why should we restrict ourselves from experimenting even if it sounds weird to other people?
I give you an example where it is desirable to let an unprivileged user perform certain tasks. You want to know if there are any employees in your office who are storing videos in their home directory and filling up the disk space to a great amount. You have a department called "Command Center or Data Center Operations or Help Desk" call it whatever you would, whose work is to monitor such activities, and you create an account "monitor" for them to monitor such activities but they are not able to do them:

View 4 Replies View RelatedI found a similar problem. The poster used a similar title "Administrative tools fail to open - karmic" I also have karmic and four tools fail to load; Ubuntu Software Center, Hardware Drivers, System Testing, and Update Manger. Synaptic and System Monitor run. I ran update-manager and software-manger and was told module pygtk does not exist. I ran "sudo apt-get install pygtk" and it said that did not exist as a package. The terminal update and upgrade also work.

How to fix the problem that is happening with gksu. It prompts me for the administrative password. I don't (for advised security reasons) have a password associated with the root account.
The sudo works fine and accepts my sudo password. Gksu fails with "incorect password... try again." error.
This is a new install of the Ubuntu Server 10.10 x64 Maverick edition.
So... this computer was given to me with ubuntu and libre office already on it (along with 125 other apps I know nothing about). I cannot watch or listen to any media. I cannot install adobe or any other program. I cannot upgrade to 11.04. I cannot get administrative access. I can't do anything. Everything comes up as an error.
View 4 Replies View RelatedNot too long ago I upgraded to 10.10 and after doing so, many of my Administrative GUI apps wouldn't work properly. For example, I can open the Update Manager, it will display all of the available updates but when I click "Install", the button "clicks" but nothing happens. The same behavior is displayed when trying to use the GUI to add a new user. I click the "Add" button but nothing happens. Similarly, if I try to change my graphics driver to the old version (not that I would necessarily want to) it tells me I don't have permission to do so. And Lastly, if I try to enable Visual Effects I get an error message saying that my graphics card does not support them.
All of this worked just fine in 10.04. And I'm not sure where something went wrong. I realized I can use gksudo for any of these applications and they work fine, however this is not really a solution for me because any time I log off, or restart, I would need to re-execute the commands to enable compiz and all that, and honestly, that's not how I want my box to work.
I thought maybe I had lost admin privileges, but I checked and I am in the "admin" group. I thought maybe somehow root took ownership of some of my configuration settings in my /home/<user> so I:

I have root access on this CentOS 5.5 machine but I am unable to run administrative commands such as service and chkconfig because it says the commands are not found.
Do I need to install additional packages or grant myself privileges that I don't have to run these commands?
I find myself using SSH from my mobile phone to manage administrative tasks when I'm away--completing updates and the like, things that can be done during normal usage but sap my RAM and CPU to the point of frustration, given the hardware I've got to work with. It's convenient, I can do what I wish (without the benefit of an X session) while I'm at work. The issue I run into is the fact that my auth.log is littered with items like this:
Code:
May 16 12:53:17 BETA sshd[18941]: pam_unix(sshd:auth): authentication failure; logname= uid=0 euid=0 tty=ssh ruser= rhost=200.111.184.180
May 16 12:53:19 BETA sshd[18941]: Failed password for invalid user lala from 200.111.184.180 port 41787 ssh2
May 16 12:53:25 BETA sshd[18943]: Invalid user master from 200.111.184.180
Which tells me that some inconspicuous person and/or botnet keeps trying to get into my system. This is generally annoying; at this point, my system isn't used for anything particularly critical; however, the fact that only failures or questionable successes--such as those from my mobile, the IP and Host of which can vary a fair bit (and the host resolution almost always fails, based on the way the IP/Host advertisement is presented to an external host is established--it's essentially manufactured)--doesn't tell me who/what has figured it out. I've done what I can to tamp down SSH access to the system, root is blocked via SSH (a moot item, since root isn't allowed locally), I've limited only my own username as allowed to connect via SSH...all it would take, though, is an alphanumeric dictionary that hits the right combination to get a password prompt, and to be able to brute-force it from there.
Overall, I know there's few, if any ways, to prevent someone attempting to get into my system via SSH; what additional steps can I take to minimize the possibility that I might end up compromised?
I am currently using Xubuntu version 11.04 and I am working with a Radeon HD 4850 graphics card. I am using the proprietary FGLRX drivers from AMD.
I have a small problem. I have two monitors, and in order to tell the computer to use the extra monitor for extra desk space, I have to get into the Administrative CCC. However, when I click on the administrative CCC, nothing happens. It's strange considering that the regular CCC works just fine.
The title says it all. Is there a way to just click ok to administrative tasks instead of having to enter my password every time? Sort of like Windows 7's UAC.I'm using ubuntu 10.04 LTS. I don't want to log in as root
View 9 Replies View RelatedI have a feeling this may be a bit of a stupid question as it seems like one that must have a very basic answer so for that I apologise but I have yet to come across or work out the solution. The problem I have is that I cannot do anything that requires administrator priviledges from within GNOME without doing it directly from a Terminal using the su command. The reason being is that GNOME will not allow me to log in as 'root' from the normal login screen. So therefore I cannot do something as simple as edit a text file that is not in /home/'my username' as I do not have the required permissions.

To get administrator rights I needed sudoer rights. I decided to come to forums to ask and this is my first post.
Is there a danger in getting administrative rights? If so, I would still rather like to face the danger than not be able to play music. And how do I get real superuser rights?

I'm asked to enter the administrative password, "Granting rights" appears in the bottom panel for a few seconds, but then disappears. I'm using Debian Lenny. This is only an intermittent problem, and if a task does fail to start, it will start on the next attempt. Tasks which have failed to start are:
*Launching Synaptic form the System menu.
*Launching a root terminal from the Applications menu.
*Launching Nautilus with root privileges from a terminal using gksu.
After coming across the following post, I thought maybe it was an issue with kernel 2.6.32-bpo.5-686, because I'd recently upgraded to that kernel too, but I'm advised that that isn't so.It was suggested that something else from backports might be causing the problem.

View 2 Replies View RelatedThis problem has taken me the whole Sunday and the only thing I've got left before start kicking my computer equipment is to ask you guys for help.I have a problem on my client side of Kerberos. Basically, none of my clients is able to make a connection to kadmin using DNS SRV-records. Only if I use the relevant directives in the krb5.conf files - it works.
Something is weird regarding the adm server. I mean, without [realms] stanza, the client does query the DNS properly for the KDC master - it can be tracked in the DNS logs and I mean, even logically - with no [realms] stanza - there is no other place than DNS where it can find this information. So, the actual authentication of the principal works. It's the kadmin-part that exits with the error message above. According to all manuals, books, guides I've read - this shouldn't be happening. The [libdefaults] with default_realm defined in krb5.conf in combination with proper DNS records, should be everything kerberos client needs. But apparently not.I don't remember having any problems like this before. This is the first time in several months a freshly install a KDC. I believe Kerberos packages did get updated few times since then. Could this be a bug of some kind introduced in never version of libs? I have the latest packages on centos 5.3.
I just installed opensuse 11.1 with only the standard user account, not root account. Therefore, my question is regarding this ... is safe running linux with no root account? Should I create a root account for adminstrative purposes? If so, how can I do that?

Each time, it rejects the password. I even tried downloading something else from the software center, just to make sure the password was correct, but the system had no problem with the password when downloading from the software center.
