hi all,

i am facing the issue with sudo commands, as i have added myself into sudoers. but now this error is occuring.
Admin is not allowed to run sudo on localhost. This incident will be reported.

thnxs in advance.


nitsss

Admin does not need sudo, if he has uid 0.Try
on admion's home dir. Reading the output from the left, it's
permissions 9all the drwx- stuff), inodes, uid, gid, etc.

Someont with root permission will have entries like
whereas a user will see
Admin, incidentally, is windows speak. There is no admin on ;inux. root has unlimited power, so use it wisely.

actually Admin is an user which is created during OS installation.

[Admin@localhost ~]$ ls -n
total 52

Welcome to LinuxQuestions

What distribution/version are you running?

Most distributions not Ubuntu based do not enable sudo by default. As an example to enable sudo on debian:
https://wiki.debian.org/sudo

Is the OS installed?
Are you trying to modify sudoers in a Live* Environment?
Sounds like it.

Did you logout and back in after adding yourself to the visudo file?

Oh Boy are you in big trouble now ... I hope your mom don't find out too...

ensure you're in the group of sudo, or add yourself to a wheel group that is sometimes in sudo, create a group called wheel, or sudo then add yourself to that group ensure it is in the sudoers file,
you can also have it so that you do not have to use a password if you did not know that, just type sudo <command> press enter

or this will get a user w/ no password needed
if you want password needed then
if you put your user name into a group that is in sudoers then just add yourself to that group instead
and make sure sudo is installed

You need to tell us what OS you're running, why you think sudo should work in the first place, and what your sudoers file looks like.

i m using CentOs 6.
After adding the Admin user in visudo file, when i m running sudo command below is the result.

[Admin@localhost ~]$ sudo apt-get update
[sudo] password for Admin:
sudo: apt-get: command not found

That is most likely because centos does not use apt as its package manager.

I think Debian distros use apt, RedHat distros use yum or rpm.

CentOS does not use apt as the package manager. Apt is a Debian package, including Debian-based distros.

thnxs to all,

After adding the user in sudoers file, i used yum cmnd & is sorted by using yum instead of apt.

thnxs again..

Glad to be of help.

PLEASE tell me you're not trying to implement the abomination that is Ubuntu's root policy on CentOS!

Leave that crap where it belongs, [in the trash] on Ubuntu, don't let it infect the rest of the Linux world. Sudo is a very powerful tool for allowing a SPECIFIC user to run a SPECIFIC task without having to get out the root password. It was never designed to give a user complete administrative privileges using their normal user password. There already IS a user who can do that, it's called root.

This sudo abuse championed by Ubuntu does not make things better or safer, it compromises security in order to make Linux more Windows-like, so it's not as "scary" for new users. Do yourself a favor and learn how to PROPERLY administer a Linux system, don't try to turn CentOS into another Ubuntu.

Yeah what he said!

go ROOT !!!

Definitely post #13 ++

Ubuntu has a lot to answer for ...
