Ubuntu Security :: "unstable" Sudoers File?

Mar 11, 2011

I am having problems on a server installation (9.10) with a kind of unstable sudoers file. Logging in as a user of group admin allows only sometimes to issue sudo commands.Most of the time I am getting a "not in sudoers file" errror.

Code:
$ sudo COMMAND
[sudo] password for USER:

Ubuntu Security :: User Is Not In The Sudoers File

Mar 15, 2011

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?

Fedora Security :: Limiting Sudo - Giving Full Privileges To The Wheel Group In The Sudoers File

Feb 15, 2011

I have previously set up sudo via adding my name to the wheel group and then giving full privileges to the wheel group in the sudoers file. Now I choose to learn to limit that. Had noticed the most frequent use I have of sudo is to run yum update. This got me thinking, could I remove the wheel group privileges and add the following line in sudoers to limit the privilege to simply running yum, and furthermore, make it so I could run yum without a password:

## Allow root to run any commands anywhere
rootALL=(ALL) ALL
Troy ALL= NOPASSWD: /usr/bin/yum

I think that would in fact work (if I understood one of the pages here, it will work). However, upon further thinking I realized that in such a case then anyone sitting at my computer could then use yum, without a password, to install or remove any file on my system � probably not a good idea. As a result I have to ask, can I tighten the privilege even further such that the only privilege so given was to run �yum update� and nothing else? (for example if they ran �yum install� it would fail). If you can do it, how?

Last, I was going to limit the privilege, time wise and try wise, by adding the following to the sudoers file:

# Defaults specification
Defaults:Troy timestamp_timeout=0, passwd_tries=3

Will that really work to limit the elevated privilege so I don't have elevated privileges lingering about, or is there a better way to do so?

Ubuntu Security :: Locked Out From Sudoers

Jun 5, 2010

A few minutes ago I accepted a suggestion from update-manager for restarting my system, such that some security updates could be effective. After restarting and login in as usual, I discovered that I could not use my adminstrative rights as a sudoer. To recover them I booted again, as root, and added my username in the "admin" group. Rebooting, all seemed well again. As an extra check I installed and ran 'chkrootkit' and nothing suspect was found.What could have hapenned? Just a glitch in the system? Can a user disappear from a group for nothing?What further checks can I make to be sure that my system is safe?I'm using Ubuntu Jaunty Jakalope amd64, with kernell 2.6.28-15-generic.

Security :: /etc/sudoers Syntax With %groupname?

Feb 1, 2010

My goal: I want to give users in the group "rtkprd" the ability to elevate their privileges and run a restricted shell script by using sudo. The full path to the shell script is /usr/local/bin/only_rtkprd.sh
The syntax of /etc/sudoers is giving me fits, to I've reduced my sudoers to a single log directive and a single line to enable the rtkprd group.

Code:
Defaults logfile=/var/log/sudo
%rtkprd ALL = (rtkprd) /usr/local/bin/only_rtkprd.sh

[code]....

Security :: Using Sudoers To Restrict Editing Of Certain Files?

Aug 2, 2010

In a recent discussion I had, I was led to believe I could use sudoers to restrict using vi (for example) for the editing of say specific config files. I know how to allow root use of vi and how to lock it down from getting to a bash prompt with NOEXEC tag,but I can't figure out how to restrict the use of vi to only edit certain files. Tutorials and howtos I have checked don't address this

Fedora Security :: Wrong SELinux Context On /etc/sudoers?

Nov 21, 2010

I'm suspicious that the context of /etc/sudoers is wrong. During the last upgrade to Fedora 14, RPM dropped /etc/sudoers.rpmnew, which had a different context than the real sudoers file. But, when I try to get SELinux to relabel the file (using restorecon or fixfiles), it refuses to make a change.

> ls -lZ /etc/sudoers
-r--r-----. root root unconfined_u:object_r:etc_t:s0 /etc/sudoers
> matchpathcon /etc/sudoers

Ubuntu Security :: Patch For Sudo That Allows Sudoers Information To Be Pulled From MySQL?

Apr 12, 2011

This may be a stupid (?) question, but does any one know of a patch for sudo that allows the sudoers information to be pulled from mySQL?
I run multiple servers with multiple people working on them and would like a one-stop update of permissions.
Yes, I could use rsync or the like, but I'm just wondering if this has been done, or could be done.

(Sorry if this is the wrong forum, I'm kinda new around here, posting wise and this seemed to fit. Feel free to move it if it's not)

Ubuntu :: User Not In The Sudoers File?

Jul 15, 2011

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?

Ubuntu :: Member Of Admin But Not In Sudoers File?

Jun 8, 2011

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?

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.
