Ubuntu Security :: 10.10 - No Admin Rights For Administrator
Oct 22, 2010
I am only user on this ubuntu 10.10 install. I have admin rights but when I try to change some settings via Ubuntu tweak unlock or alter user and groups via advanced tab I never get the option to enter my password. I have added a new user 'tempuser' via safe mode and this user is administrator too but everything works fine from this user..
Results from $ grep admin /etc/group
lpadmin:105:heath,tempuser
admin:119:firstuser,tempuser,heath
Results from groups
admin adm dialout fax cdrom floppy tape audio dip video plugdev fuse lpadmin sambashare
I am thinking of making a fresh install if I cant sort this but would like to fix if possible.
I have been wondering if a guest user could compromise a machine which is set in the following way: they are not able to open the computer case, to boot from either an USB flash drive or an optical-disc drive, nor have any knowledge of the administrator-user password. Thus, they are landing on their guess account, and have to work their privilege escalation from there.
Therefore, what can they do to gain it? Could they download or otherwise install or run from a thumb drive an application that could be used to crack the administrator-user password? Because, it seems to me, could they enter into the system such a password-cracking application, the whole system could be compromised given the administrator-user password contains less than 9-or-so characters. What do you think? Can I lend my computer to anybody without them having beforehand gained my trust in them? Is the reasoning reasonable?
I cant change my user settings (password, login screen settings etc) after upgrading to 10.4 on my desktop pc. It says I don't have rights. I'm the only user, no other profiles. Otherwise seems to be working fine!
I've got a Dell laptop with a dual boot with Ubuntu and Windows 7, but I want windows 7 to be the default OS. I can't seem to find anything on Ubuntu with any information. I had a look at some forums and it said I need to go into admin, but I don't think I have it. Does anyone know how to get Admin rights and how to change the default OS?
I am semi new to linux and i was getting the hang of it until just recently. I'm trying to do some web design using php and mysql. In my reference material (the all in one desktop reference {for dummies}). At some point I needed to do something in /var/www but I ran into a permissions problem so I typed: Code: chgrp -v -r guy0203 /var/www 405 chgrp -v -R guy0203 /var/www 406 chown -v -R guy0203 /var/www
Afterwards in some subsequent step it suggested putting the files in /usr/src/mysql. Since I didn't have that folder I used mkdir and created it. Then I tried adding the files I needed to that folder and got denied on the grounds of not having permissions once again. So tried something like this: Code: 451 chmod 777 /usr/ 452 sudochmod 777 /usr/ 453 sudo chmod 777 /usr/
It was a 755 originally but I couldn't copy those commands. It turns out as that I had two terminals open in different desktops. one of them was a root terminal. It was at this point that realized that I was in that root terminal and decided I was done 'learning' for the day. I decided to listen to some music (which is located in my windows partion) and ran into a problem. The prompt that pops up to normally asks me for my admin PW to mount the drive. Now just vibrates like an incorrect entry was received, says authentication error and says I am not authorized to mount that drive then I went back to terminal to fix it, and when I tried to elevate myself to SU:
I got this: Code: guy0203@guy0203-laptop:~$ sudo su sudo: must be setuid root guy0203@guy0203-laptop:~$
I don't know what to do now but I think I totally killed this OS. If so is there anyway to save things if I have to reinstall?
I created a custom linux distro that originated from ubuntu server and I installed time-admin and want to change the time without admin rights. Is this possible?
I have OpenVPN setup and running on my home server (Lucid Lynx). I move around alot and use Portable OpenVPN to connect to my home server. The problem is a lot of the computers I use I do not have admin rights to install the necessary routes to connect. So my question is this. Can OpenVPN be configured to use PPTP protocol? Because I have PortableVPN on my U3 flash drive and that VPN client does not need admin rights to run. If OpenVPN cannot do this, and from my understanding of its archetecture it cannot, but I must admit i am no authority on the matter. Can you suggest a workable solution, ie. install and setup this server software and use this portable client software.
I am using linux mint and have installed Netbeans on it but whenever I run netbeans from accounts other than root it throws an error for not having permission to start glassfish server of netbeans. I also tried running this application using run as administrator option but then the application does not start.
So is there a way to assign netbeans admin rights permanently so that whenever I start this application from other accounts I should not face this error?
I have moved to a new place and they expect me to work without root access to my machine, but I need to compile and make some software. However I get the following error:
mkdir: cannot create directory '/usr/local/ope': Permission denied chmod: cannot access '/usr/local/ope': No such file or directory mkdir: cannot create directory '/usr/local/ope': No such file or directory chmod: cannot access '/usr/local/ope/bin': No such file or directory make[1]: *** [/usr/local/ope/bin] Error 1 make[1]: Target '_installall' not remade because of errors.
I have been allegedly been given admin rights - but do I need root to do this?
I'm having a bit of a problem after joining Ubuntu 9.04 to my company's Windows Domain. I can log in and use sudo just fine but I don't have access to certain things in my menu (i.e. "Add/Remove Software") and I can't open the User Manager. I manually edited the /etc/group file as root and added my username (username@domain) to the appropriate groups but still no luck.
I have created a new user using sudo adduser "user1" from the root .but this user does not have full admin rights...How to give full access to this user1?
I'm a new Ubuntu user and a Python programmer, it's the first time that I use Python in Ubuntu so it's a bit confusing me. If I want to save a Module or something in a specified map, I get 'Errno 13', it says that I don't have permission to edit, do thing in that map. And this is also for importing files with Python. I logged in from Terminal with 'sudo -i' and closed Terminal, but the problem keeps repeating. How do I login as Admin or Root and stay as Admin or Root? I need right to edit/read files as well as root and normal user.
An example: Python file: test.py -> test = open('/a.txt', 'w') test.write('Test - Test - Test') test.close
When I execute this, I get in the Python IDLE the 'Errno 13' problem and below the 'Errno 13' it says that I don't have permission. Who know how to stay logged in as root, even if the user has not logged in or isn't this possible, if it isn't then I just want to get files moving, editing/erasing etc.
One of the feature in my application involve changing of hardware setting. This require the user to be root or have administrative right.Before my application enable that feature, I want it to check whether the user is "root" or not, or whether user use "sudo" command to run the application or not, or whether the user has administrative rights or not.What are the codes or library that can do this?
NOTE: Sometimes, advanced linux user may set the user id of root to something else other than 0. So, getuid() may not be helpful in this case.
i have a ubuntu server box with samba 3 as domain controller with all windows 7 clients.i am wanting all users to have local admin rights so they can install programs etc.
I would like to install a more modern version of GNU utils (coreutils) on a debian linux system where I have no admin rights. Is there a way to do that?
The rationale is that I need a more modern version to the one installed in the system where I intend to run my analysis. I am trying to use "sort -R" or "shuf" to randomize lines in a big text file.
Certain commands like: fdisk -l nmap -sT 192.168.0.1/24 iftop
require administrator privileges to run. A while ago i read a post(forgot where i read it) about being able to let a user run these commands in a script (that contains the desired command) created by the administrator/root without the user having to do a sudo and entering a password. Does anyone know how i can go about doing this?
I love My linux OS, and I carry It with me all the time in USB. I used to be able to boot from USB in the University computers, but not any more. Now it required Admin password in order to boot from CD or USB. I tried The VMWare, but I didn't like it. Is there any way I can get around it.
I am novice user of linux. I need to know how to configure firewall so my system cant be compromised...In windows my system was greatly compromised. keyloggers were installed without my approval and my desktop was taken on remote. What should I do so without my knowledge no software can be installed and i can close all ports and only open which ever port is required to open. What should i do so my desktop cant be taken on remote?How do I configure user rights ? So except me no one can install any software. I will have another general user id for internet surfing
newbie changing to Linux, but not comps.as I said in newbie forum, putting them together since mid 80's w/5150's. that said most exp is old dos command line and commodore 64 basic. our economy here in USA causes change for many of us. I am now reading CompTIA study guide for Linux+ certification by Robb H. Tracy, pro Linux administration by James Turnbull,Peter Lieverdink, and Dennis Matotek. I have downloaded and installed PcLinuxOs, Fedora, SuSe.(three separate disks) have Linux Mint, Ubuntu, on cd. I also have Helix, DEFT, FIRE, FCCU, and Live Forensics Toolkit for Windows. because of pending legislation in our state and current or pending in others, taking classes@community college for private investigator. end goal?: Linux Systems Administrator/security/private investigator specializing in forensics?as I learn I'll probably install a server version on 1 of my drives and ask some of you to use it to work with/hack me/give me help in general.
I have setup a VPS server, created two accounts to two domains respectively, and in one account I built a tool to manage other accounts. I have been rigorously researching and found information, however not implemented yet, about granting apache sudo rights through an interface on one account, so that it can execute scripts as root to manage installations in other accounts. what I mean this is my tool will use 'rsync' to duplicate installations from any account into any account.
My question for security, is it secure to grant apache sudo rights? I have not resolved successfully granting it permissions, and I would not want to waste my time investigating more on it if it can compromise the system in any way.
In your experience, is it feasible to build such a tool like I described? I have the tool working to copy within account and to addon domains and it works great, but I want it to manage all accounts on the server.
Quote: The open-source Linux operating system contains a serious security flaw that can be exploited to gain superuser rights on a target system. The vulnerability, in the Linux implementation of the Reliable Datagram Sockets (RDS) protocol, affects unpatched versions of the Linux kernel, starting from 2.6.30, where the RDS protocol was first included.
According to VSR Security, the research outfit that discovered the security hole, Linux installations are only vulnerable if the CONFIG_RDS kernel configuration option is set, and if there are no restrictions on unprivileged users loading packet family modules, as is the case on most stock distributions.

I'm trying to edit a "xl2tpd.conf" file but it always says I have no write permission tried to add my account to admin group but it says something about not able to lock on password try later.
I think ubuntu/canonical should start releasing a new flavour geared towards meeting needs of computer security professionals just like backtrack distro
I try to install my printer again after reinstall ubuntu 9.04. ("downgraded from 9.10"). Instead of asking for the local-user-login password, as it does for other system changes, it asks for a root password that I never had. What happened? How can I set this right?I made a printscreen.
I need to create a number of internal Linux users for admin purposes. I do not want these users to appear on the initial console login page just after Fedora boots up, as users who can attempt to log in, and I do not want to allow these users to log in directly. I merely want these users to be accessed via su, just like the root user.
i am relatively new to ubuntu. Just recenty i have not been able to access certain files(for example the history and bookmarks in the firefox folder), download files individually from the internet(music,fonts,etc), recieving an error message
i have sudo priveleges and can install via update manager. i read somewhere that compizfusion might affect access permissions and i do use compiz and emerald at the same time.
