Ubuntu Servers :: Unable To Add User Directly Into The Sudoers File
Jun 22, 2011
I'm running Ubuntu Server 11.04. It came time to add User to the sudoers file: so I decided to simple add User to the admin group: usermod -a -G admin user Then I used visudo to check if admin users had been set to receive sudo privileges. I uncommented the line admin ALL=(ALL) ALL. Nothing happened. I've even tried to add user directly into the sudoers file as user ALL=(ALL:ALL) ALL, but that failed too.
I just installed Gutsy server. It is the only disk I can get to boot on this old PC trying to salvage. I'm at the "SERVER LOGIN" prompt. I created one user during the install. I can login as that user, but that user has "...Is not in the SudoersFile." How do I setup this user to be in the sudoers file, without having any ability to make changes to the system?
I have a bit of a problem... I thought (for certain reasons) I would just add myself to root group and therefore gain some more rights for my account. I could sudo before... But once I gained the root group as a secondary group it says I am not in the sudoers file anymore...
Code: id uid=1000(kosta) gid=1000(kosta) groups=0(root),1000(kosta) Code: sudo ls [sudo] password for kosta:
kosta is not in the sudoers file. This incident will be reported. It is really weird and messed up. I can view sudoers file but not edit it... I can cat passwd but I can not view syslog. Is there any way to fix this without having to reboot to recovery mode? And why the heck is this happening after all?
I get this message if i try to use sudo/gksudo. What causes this, how can I solve it? It has been working for years. If i remember correcttly there was a sudo update few days ago, maybe it doesnt work since then, i havent used it in the last few days.
Suddenly I am not in the sudoers file. I am not sure how to recover from this. I have no grub screen at bootup, so I can't boot into single user. I think I am going to have to boot a live version of ubuntu to start with. Is that right? What's next after that? Also, how could this happen, I haven't touched the sudoers file or added users or anything like that (well not that I am aware of) I am a little concerned that this may be the result of someone breaking in? Would this be a likely symptom?
How do I add myself to the Sudoers File? When I go to use the "Sudo" command, it tells me I am not in the Sudoers File, so I have to do "su -" to bypass it for the time being. How do I add myself?
I wanted to do an installation from my user login so I typed sudo make install then it says <my_user_loggin> is not in the sudoers file. This incident will be reported. How to correct this matter...
I need to install a package. For that I need root access. However the system says that I am not in sudoers file. When trying to edit one, it complains alike! How I am supposed to add myself to the sudoers file if I don't have the right to edit one? I have installed this system and only administrator. What can I do?
Edit: I have tried visudo already. It requires me to be in sudoers in the first place.
is it possible to do so? I mean, I want every user to be able to run '/bin/x' for example, as root without entering a password. I know the security risks, but I'm trying this in a risk-free environment which security does not matter very much.
Warning: Do not edit /etc/sudoers directly with an editor; Errors in syntax can cause annoyances (like rendering the root account unusable). You must use the visudo command to edit /etc/sudoers. In the previous section we added your user to the "wheel" group. To give users in the wheel group full root privileges when they precede a command with "sudo", uncomment the following line:
%wheelALL=(ALL) ALL
so i signed in as root and typed in visudo now i alreayd made the changes but how do i exit and save super+x doesnt seem to do it for me since im not using nano and not supposed to cause it causes errors
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?
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"
I have a fairly complicated request The short version is, I want to set up a system so that any user can change the ownership of a certain set of files at any time without root access. I think it's possible to set up sudoers to do that, but so far I have failed miserably.I have tried setting up a wrapper script around chown, then putting that script into sudoers, but it didn't work. Here's the script and sudoers (paths changed to genericize them):
Code: #!/bin/bash #this script moves a copy of the code
I managed without knowing to remove my user from the sudo users group. I did usermod -G fuse <username> and now I can't sudo anymore. How do I get back to the promised land?
How do i add the default normal user to the sudoers group? Is it normal for the main user to be kept out of the sudoers group or did i do something wrong during install?
When i installed the new version of debian on my laptop to try it out, i noticed that i can't sudo as my main account is not in the sudoers list and i cannot put me in because i'm not sudo.
Code: cesar@debian:~$ groups
cesar cdrom floppy audio dip video plugdev netdev powerdev scanner bluetooth I have to enter as a root account but don't know how, plus i forgot my root password.
note. i dualboot with ubuntu 10.04 and grub is managed by it.
I have tried several things to attempt to fix my sudoers file however it is still coming up with errors. The error says
[code]...
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.
I need to add a user to the sudoers in my vps host and edit a couple of files and I just cannot make sense of visudo, vi or nano. The tutorials I find on the net just take too long to study and they are never complete, can someone explain what I need to do? I am running Debian 506.
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
Is it possible to disable all passwords in debian. I do not need any security usernames and passwords. I don't want type sudo all the times and i want free acces all the time. With debian i allways have some premission problems and why i need a password for my home computer?
1. For example today when i tried to install a file debian told me that my username is not in sudoers file. How can i fix this? 2. Is it possible to disable all passwords and asking admin premission, i dont need that kind of ??? for my home computer. (including the login screen user/password asking) And i am sorry for my grammar errors, i hope you can still understand what i have tried to say.
I changed my user name, and now the Terminal shows my new user name.I log in with the same user name and the same password. But after changing the username, I can't get anything done as sudo. It says that I am not in the sudoers file, and I can't get in at all. I tried sudo visudo, sudo -i, sudo -l..When, I wrote sudo -l the following came in the Terminal.How do I get into sudoers file and give my new user name ariya the root privileges. Even my old user name doesn't work at all.
The normal user is now in the sudoers group. How can i allow it to install programs using it's own password rather than having to know the super-secret Root-Users password?
I want to create a group called scripts, add www-data to that group. I then want to edit the sudoers file and tell it that the script group doesn't need a password. Where should I put this line excatly in the sudoers file?
I was planning on getting the USB to work in my 3.2.4 Oracle virtual box, and I found a post that says you have to be a part of vboxusers. I ran > sudo usermod -G vboxusers alias and then id to see that I was a part of the vboxusers group. After I installed an update which required restart. That is right! I am no longer in the /etc/sudoers file!!!
I am using Ubuntu 9.10 and I lost my sudo accesses for the User. So I am not able to use sudo command as I get the error,user1 is not in the sudoers file. This incident will be reported.Also I tried to login into the root usersu rootit will ask for the password(actually I dont know the password of root but after pressing enter I get the following error)su: Authentication failureI dont know how to add the user1 into the sudoers list.Also, is there any way to add the current user into admin group without using "sudo".
I'm trying to add my single user 'moreaue' to the sudoers. this user seems to be have admin privilege but is not in the sudoers:
Code: moreaue@bloom:~$ sudo ls [sudo] password for moreaue: moreaue is not in the sudoers file. This incident will be reported. moreaue@bloom:~$ su Password: root@bloom:/home/moreaue# adduser moreaue admin The user `moreaue' is already a member of `admin'. root@bloom:/home/moreaue# exit exit moreaue@bloom:~$ sudo ls [sudo] password for moreaue: moreaue is not in the sudoers file. This incident will be reported. moreaue@bloom:~$
As you can see I can connect as root, run the adduser command which says the user is already admin... but then the user is still not a sudoer. Of course I can edit the sudoers file manually, but I wonder what is going wrong?
everytime i try to do anything with sudo i cant and this time it was extremelly costly. From now on i don't want to risk anything like this again and i need to be able to sudo.
