the sudoers configuration file is set to the default as I have ran a dpkg on it, have also uninstalled and reinstalled it, and went over the configuration file ensuring it looked like the defaults I had seen online.

Ubuntu :: Error: Sudo: /etc/sudoers Is Owned By Uid 1000, Should Be 0

Jan 4, 2010

I have a problem, I changed the own of all the etc folder, it was a mistake, but I can't change it again, now, I cant use "sudo" because root is not the own. When I try to use "sudo" this is the error: sudo: /etc/sudoers is owned by uid 1000, should be 0. so, the own is my user instead of the root. How can I change it again?

Ubuntu Servers :: Error - /etc/sudoers Owned By Gid 1001 Should Be 0

Feb 11, 2011

I've got the following error message on my Ubuntu 10.10 Server after messing up the root permissions.

Code:

/etc/sudoers owned by gid 1001 should be 0

I've found some threads on this forum but they do relate to Ubuntu Desktop while this is Ubuntu Server. Therefor I started a new thread. Hope you don't mind. I've tried the following command:

Code:

chown root:root /usr/bin/sudo

Code:

chmod 4755 /usr/bin/sudo

The first command works, the second returns error: No permission

Slackware :: Error - Libusb Couldn't Open USB Device /dev/bus/usb/001/001: Permission Denied

Mar 24, 2011

Hello,

this error spams about 100 times, then the scanner does indeed work. So I'm not completely broken, but the error messages are of concern, and it slows down the process of scanning for the time it takes to do the messages.

Error in console:

libusb couldn't open USB device /dev/bus/usb/001/001: Permission denied. libusb requires write access to USB device nodes.

my sript runs:

scanimage
--device $MODEL
--resolution=$RESOLUTION
-x 5104 -y 6840

my groups:

uid=1000(fogie) gid=100(users) groups=100(users),7(lp),11(floppy),12(mail),15(man),17(audio),18(video),19(cdrom),20(games),21(sloca te),83(plugdev),84(power),86(netdev),93(scanner)

Even a simple:

scanimage -Lv

in console gives this on a separate --current pc as well.

Server :: Uppercase Usernames In / Etc / Sudoers Triggers Warnings

Jan 6, 2010

We're syncing users from Active Directory over to our linux LDAP server (Red Hat Directory Server). The user names on the AD side are all written in uppcase letters, which is the company policy.The uppername usernames causes problems when setting up /etc/sudoers, since uppercase words are interpreted as aliases. For example, if I add user KENNETH to a User_Alias (i.e. something like "User_Alias ADMINS = KENNETH"), I will get a warning from visudo which expects KENNETH to be an alias and thus not a username. Despite the warning, sudo does seem to work correctly. But is there a way to tell visudo or sudo that usernames are uppercase, and should not trigger a warning? Or are there other ways to go about this sort of thing?

When trying to mount samba share off of domain member server sysimage in Windows receive error "There are currently no logon servers available to service this logon request". When trying to mount.cifs from PDC to samba share on sysimage receive error "mount error(13): Permission denied".

Server :: ProFTPd - Upload Anything Or Create Directory: 550 Permission Denied Error

Jan 7, 2010

I have proftpd @ Ubuntu 9.04 server. It authenticates users via Auth file, e.g. those are "FTP only" users, not real linux users. Each of them has assigned home dir in the same auth file. They also get Chrooted into it, e.g. default dir is ~ in proftpd.conf They can connect and download files successfully, however, they cannot upload anything or create directory: 550 permission denied error.

When I login via ssh and change user to proftpd user, I can create directories in that particular place, so I guess it's not Linux permissions problem? Or is it? /var/log/daemon.log is the place where proftpd stores its logs, but I cannot find anything relevant there

Debian :: User Not In Sudoers

Feb 21, 2011

I have installed debian 6 recently, and during installation I selected not to allow root login (and thereby enable my standard user to use sudo).If I check sudoers (by using visudo) my standard user is not listed anywhere, but he can still use the sudo command without any problems.Where else could this permission be stored?

Fedora :: Sudoers Can Not Display

Mar 14, 2010

I am going to school for IT Security and will be taking my first Linux class this semester. I have dabbled a little bit in Linux before this but never really had the time to get to involved so I put it off untill now. Now I am forced . Anywho...I just installed Fedora11 (dual booting with Vista home basic) and the first thing that I am trying to tackle is install VMware. I have access to a bunch of Window OS's because of school and would like to create a 'virtual' version of windows for things like iTunes. This way, i have to force myself to use Linux for everything and I can install it on the whole PC. Until then, I am going to dual boot. When I was trying to install VMware, I tried to do it from the Terminal using sudo sh then the file name which is a .bundle file, I typed in the password and it said that my account was not in the 'sudowers' profile or something like that. I read on-line that you can modify who can sudo and who can't in the ect/sudoers file but if has an 'X' at the top right and I can't open it. It says 'Could not display "/etc/Sudoers". I tried to use visudo in the terminal and it says that permission is denied.

Red Hat / Fedora :: Add User To Sudoers

Jul 16, 2010

I recently installed Fedora 13 "Goddard" using the graphical installer (although I prefer the 'text/ reduced graphics' option.When I start the system (after installation completes), it runs in graphical mode and presents me with a graphical login prompt. However, due to security reasons (I'm told), it won't let me log on as the root/ admin user (which is fair enough).If I log on as another user (eg : alpha, charlie or delta, for this example), I can't edit the sudoes file to add one of these users (alpha) to the file. This is because these users aren't in the file, as far as I know.

At no stage during installation was I offered an option of either setting the runlevel or adding a non-root user to the sudoers file.I have found a way to change the runlevel setting, so that is not really an issue.What I would like is either of the following :

1. A modification to Fedora's graphical installer that allows for an explicit option to set the runlevel (graphical/ command-line) and another option to add the first created non-admin user (alpha in this example) to the sudoers file.

2. Information on how to add a user to the sudoers file without adding all others (eg : alpha, but not charlie and delta, in this example).

I have read the relevant man and info pages for the su, sudo, sudoers and visudo commands, but I only got confused. (I don't know BNF/ EBNF and I would like a solution that doesn't involve having to learn these BNF dialects, although I will if I have to.)Also, I have seen solutions that show how to add all users, but not individual users, to the sudoers file. What I want is to add an individual user (if this isn't clear already).Please feel free to send me an e-mail about this post : nigel.nq.ngw[at]gmail[dot]com with the subject line "Linux Forums - Fedora 13 Add User to Sudoers"
