General :: What Are The Percentage Signs For In The Sudoers File
Aug 18, 2010
In my sudoers file, there are lines that begin with #, lines that begin with % and lines that begin with neither. The # is definitely being used to comment out lines, but what does the % do? Is it a comment marker too?
I logged in as root and was trying to add a user to sudoers, but then when I tried to save it said that the file was write protected and couldn't be saved. However, when I returned to look at the contents of the sudoers file, they were all done. The file is now empty.
1- How can I restore the contents of the default sudoers file. (I have FC12) 2- How can I add a user (no password) to the sudoers list without this happening again?
1.sudo command runs command as root,is that our name should be mentioned in the sudoers file of root?i got the error like this-"sandyain is not in the sudoers file.This incident will be reported."so what is that mean?
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.
Relatively new to Linux, but I'm trying to grasp the proper way to modify the sudoers file. As an example, what would I have to modify in /etc/sudoers to allow a user (say 'user1' for the example) to be able to add/remove software through yum? I'm aware of the fact that I need to use visudo and how to use the vi editor. I've Googled this topic and while I've found a number of pages on the topic, I never see many examples.
I'm trying to follow this guide http://tech.blog.box.net/2007/06/20/how-to-debug-php-with-vim-and-xdebug-on-linux/ and I need to compile Vim with signs and python options.I have: downloaded the latest source with hg clone https://vim.googlecode.com/hg/ vim uncommented the signs feature in src/feature.hran ./configure --enable-perlinterp --enable-pythoninterp with no errorsran make with this output and errors that I don't understand and can't find on google:
Recently I migrated from Ubuntu to Debian, first thing i wanted to do was to give myself sudo permissions and lock the roir account. By default sudo group don't have permissions to do this on debian, so i wanted to edit sudoers file by typing visudo. But i keep getting this error: Error opening terminal: vanilla How can i solve this.
since a recent upgrade to Mandriva 2010.1 I am not able to 'sudo' as administrator or when I use the 'root' password. I am the only user on this machine (Dell Inspiron 530S multi-booted with Window's Vista Home Premium, Ubuntu 10.4, and Mandriva 2010.1). I can get into the 'Manage Users' section of the control center by authenticating as 'root' but I can't access 'sudoers file' from command line.
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.
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.
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.
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 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 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 am in need to create a script that queries how large a partition is and when it hits a certain percentage (say 90%) it will execute another script that tars up certain files (or they could just be part of the same script). I would create a cronjob that runs this script once a day.
I have the script that tars up the files I need, sets permissions, etc. (btw, the files in question are audit logs). I just need the part that runs something like a df -h and takes the use percentage of the /var partition in that query and if that percentage is greater than/ equal to 90%, it kicks off the tar script.
Here is a sniplet of the df -h with just the /var partition shown:
Quote:
So, when the cronjob sees that the Use% is >= 90%, it would kick off the tar script...if not above 90%, it closes.
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 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.
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!!!
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?
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".
