General :: Grasp The Proper Way To Modify The Sudoers File
Jun 3, 2010
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 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?
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 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.
I am setting up a file server using Ubuntu and want to make sure I set up a folder structure that will last. Where should I be placing everything that I am sharing (Music, Pictures, Videos, etc)? In theory, if I was setting this up on Windows, I would create a folder directly under C: and set up the different areas of sharing under that (not that that approach would be best either).
Based on constructive criticism, the question is rather ambiguous. My question could be restated to ask "Where shouldn't I set this up? Would /usr be an appropriate place to start? Or would /opt be better?
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 am trying to install Oracle ebs on my machine and I keep getting the above error.
it compares two files using md5... if they are same , a corresponding character is output to a text file .. but the problem is it gets appended by default.. is there any way to output in a normal way because the text is a message and it should be of proper format here is my script
Code:
#!/bin/bash g=`tail -1 new.txt|head -n 1` array=( a b c d e f g h i j k l m n o p q r s t u v w x y z ) for((i=1 ; i <$g+1 ; i++))
[code]....
the message is supposed to be hello , i need to get rid of the endlines somehow..
I need to modify a file that contains \tsus.fbfs.comappsdataStormLossProduction and replace the \tsus.fbfs.comappsdataStormLossProduction line with rm -f /mnt/nfsvol/PC/SLR/
I have tried:
But it provides an error on the second . I need to change this in place and not redirect to another file.
Is this possible? I have used sed and awk before but not extensively.
Whenever execute the below scriptlet with out proper file name it deletes /tmp directory .I guess this is because value of variable a didnt get initialized and there for rm -rf /tmp/ get executed and entire /tmp directory get deleted.How would i avoid any empty variables to be used in script? as this is a classic case of destructive script.
Code: #!/bin/bash echo "Enter file to delete from tmp"
Why is the info in the (BASH_Profile) file different than (echo $Path). Is the Profile file just there to modify another file and not actually hold information?
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.
If I want to modify my .bashrc file to change the HISTSIZE would the following command be for example; HISTSIZE=200? And if I want to change the DEBUG_LEVEL to 8 would the following command be; DEBUG_LEVEL=8?
But the idea is that I can add a line to a section and it check if the section is defined, (add the definition if not), the property is defined, let it undefine (erase the line), (and delete the section header if there is no property defined), etc...
I didn't find anything except gconftool-2 but it do not explain how to modify other files. (there is a shema file there).
there isn't a program/script to achieve this, but can easyly be made for every config file, If someone do something like that, with a little database of which markup use each file, it could become really popular.
I am in the process of setting up an Asterisk server with Broadvoice services. I am having issues with making outbound calls and Broadvoice suggests I modify the /etc/hosts file in order to add their proxy server IP address and name. I login to my server as root and get the following command line header
[root@root tmp]#
I entered cd thinking this is what I need to change directory but fails. What is the command I need to enter in order to get to the /etc/host file so I can change it? How do I confirm an /etc/host file even exists?
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?
