It's been a few years since I last installed Ubuntu. I searched the forums and can't seem to find the answer. I want to be able to do a "su root" and have root access. I know Ubuntu wants you to do the sudo command, and I know you can really mess things up being root. I know I got this to work before. What do I need to do?
View 3 RepliesOriginal HOWTO can be found at: [URL]... So the other day I was in IRC and someone had brought up a problem where they created a new Administrative user, but didnt have rights to use sudo. Looked into the problem a little bit to figure out what was wrong, and it turns out that when you create a new user through the user manager (in kubuntu, anyways. Havent tested in Gnome.) the user gets added to the adm group, however, a quick look at the sudoers file shows that its looking for users in the admin group to allow the use of sudo. So, to solve the problem we do the following: If youre on the new admin user (which Im assuming you are) use the following commands:
Code:
su [insert username of old account without brackets]
sudo usermod -G admin [username of new admin account without brackets]
exit
Then simply logout, and then log back in (not always necessary, but the easiest way to flush the permissions.)
Code:
su [insert username of old account without brackets]
Means were going to Switch User to the old admin account
Code:
sudo usermod -G admin [username of new admin account without brackets]
This simply adds the admin group to the secondary group list for the new user
Code:
exit
Pretty self explanatory
How to become a root user without using sudo?So,that i can become super user to edit configuration files in etc directory.
View 1 Replies View RelatedI recently re-installed my U10.04 and this time around, I added a root user and brought the permission levels of my default user to "Desktop User" as well as elevate the root permissions as explained elsewhere in these forums. Everything went fine until I wanted to "sudo" something from the Desktop User account terminal. I use Skype a lot and preferred to use the repos to get it loaded. Into synaptic where it asked me for the password. I entered the password and I was rejected. Ok, maybe I typed it in wrong. Tried again. The third time I checked in an editor to make sure I wasn't in all-caps. Third time OUT!
Switched user to root and there were no problems. Enabled the partner repos, installed Skype, as well as all the other stuff I use to run my home office. I have missed something, I know I have - perhaps a setting somewhere in the user permissions. I don't want to have to switch user every time I have to make changes to the system. Alternatively, if it's better practise to just leave my system as it is for security purposes I'm not running a server, but I'd like to have my system as secure as reasonably possible without elevating my problem to "paranoid security" level.......
I was wondering if someone had a logical reason and therefore complete, hopefully that makes total sense, for why when I install Ubuntu I cannot use the 'sudo' command either with root or user passwords. Even if I try to edit the permissions for sudoers, I still recieve an error message that says access is denied and so as the root user on my pc I don't understand why I can't put my name in the sudoers file or use the sudo command with the correct password.
View 9 Replies View RelatedI have a weird question about the sudoers file. Currently, I am running "Red Hat Enterprise Linux ES release 4 (Nahant Update 8)".
I edited the sudoers file (via visudo) and added the following:
User_Alias RPTS2 = vtmtest
RPTS2 xxxxx = (jboss) /oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
The user (vtmtest) issues the following command
sudo /oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
and gets this message:
user vtmtest is not allowed to execute '/oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh' as root on xxxxx
When I look at the log, I see the following:
Jan 25 14:17:57 xxxxx sudo: vtmtest : command not allowed ; TTY=pts/12 ; PWD=/export/home/vtmtest ; USER=root ; COMMAND=/oracle/app/oracle/apps/rptsd/deploy-jboss/deploy_rpts_jboss.sh
1. Why does sudo try to run as the root user, when I have specified in the command to run as jboss?
2. Do I need to specify anything else so that this command can run as the "jboss" user and not "root"?
I want to use root password instead of adding my user to the list of sudoers,In Arch wiki ander Root password:Users can configure sudo to ask for the root password instead of the user password by adding "rootpw" to the Defaults line in /etc/sudoers: but that did not work for me. it asks for root password.Why do I want to do that:
1. I want to do that, I like sudo more than su -c 'some_command'.
2. sudo enables bash completion, su -c does not.
3. I don't want to add my user to sudoers list.
I found many users Suggesting alternatives and lowering the important of my need for this, when I asked this question in anther please.
Can a sudo user do everything what a root user can do? I read sometimes expert say "You should run it as root rather than sudo user".
View 14 Replies View RelatedStumped on this one. I'm trying to set up limited sudo authority on a desktop with some sensitive user data, and as an extra precaution I wanted to configure sudo to use a password other than the user's or the root's. I'm not sure how to do this. From the manual, we have a few options, such as "runaspw" or "targetpw", but none seem quite what I'm looking for.For instance, "runaspw" could be used if I created a user for nothing other than sudo(ing) purposes, but it requires you set "runas_default", which means that said user would have to have authority to execute said commands in the first place. This is workable, but seems like a lot of extra configuration for each specific command that I want to run, as well as creating some issues with simply commands such as "shutdown" or "reboot". Also, "targetpw" can be used in conjunction with a sudo(ing)-only user if I set an alias, but, again, this isn't quite what I am looking for.
Ultimately, what I am really concerned about in this situation are keystroke loggers, so I would prefer to avoid repeated entering the user or root password when performing administrative tasks. Also, I would prefer not having to create a sudo(ing)-only user as mentioned above to prevent a comprimised password resulting in an attacker being able to log into my system.
I'm the only user, can login (meaning I know my pass). But cannot Sudo. I'm on Ububtu Studio, the latest release. Doesn't make any sense.
View 2 Replies View RelatedIn order to allow me to shutdown my PC from within fluxbox without being root I ran "visudo" and added the following line:
Code:
psionl0 ALL=(ALL) NOPASSWD: ALL
A check that the line had been accepted showed all ok:
Code:
bash-4.1$ sudo -l
User psionl0 may run the following commands on this host:
(ALL) NOPASSWD: ALL

I need sudo for www (apache) user to run a shell script('ip.sh' contains iptables rules) from cgi-bin directory via browser using a per script. I edit sudoers( www ALL=(ALL) NOPASSWD: ALL ),but when run the bellow command that's with err:
# sudo -u www sh /srv/www/cgi-bin/ip.sh
iptables v1.4.4: can't initialize iptables table `filter': Permission denied (you must be root) Perhaps iptables or your kernel needs to be upgraded. And:
# ls -al ip.sh
-rwxr-xr-x 1 root root 243 Sep 7 14:18 ip.sh
I edit sudoers so
'www ALL=(ALL) NOPASSWD: /srv/www/cgi-bin/ip.sh,/usr/sbin/iptables' too. but it doesn't work too. how can I execute this script via browser ?
I am trying to get a non-root account on one of our servers to run a script with sudo capability. To that end, I went into the /etc/sudoers file, and added the following syntax:
Code:
## Enable the nagios user to run the check_iptables.sh script as root
nagios ALL=NOPASSWD: /usr/local/nrpe/libexec/check_iptables.sh, /sbin/iptables
I restarted the nagios service, and tested the results. The results were the user account still could not run the script due to the user, nagios, not having permission to run the iptables binary.
Is there another step(s) that I need to take in order to get the sudo access available to the user account?
Prelude: OpenSUSE 11.2 (2.6.31.8-0.1-desktop), installed Novell client 2.0 SP2 (novell-client-2.0-sp2-sle11-i586.iso).
I found that if any usual user is logged into a NDS-tree, then _local_ root has full access to user's network shares, including the user's home directory located on remote Netware-server. Is it by design or
have I missed something? Nevertheless in windows local admin has no access to network resources mounted of any other user. If you runas shell (as admin) then admin in principle can't "see" network shares which were mounted (connected) by other users - they are accessible ("visible") per session.
I need to provide sudo access to Oracle User, run only this particular "SRVCTL" command.
Do I need to edit "sudoers" file .if so where do I need to add these two lines in sudoers file.

I made a Desktop User account. When I went on that account, it allowed me to execute sudo as if I was an administrator. I don't know what might be causing this. I do have ufw set up and blocking incoming connections. Do you guys know what might be at the root of this?Also, when I used sudo from the user account (which I shouldn't have been able to do), I provided the password for my admin account.

View 2 Replies View RelatedBefore, the "sudo cp -r" command automatically set the permissions to make the directory / files can be accessed by others.
But, after I reinstall Ubuntu 9.10 and apply all the latest updates, "sudo cp -r" command set the files to be accessible by root only.
After I copy the codecs directory to /usr/lib by using the above command, not only I cannot view the files inside, SMPlayer and other player software cannot access the directory.
To fix this, I have to run the chmod command to change the permissions.
Does anyone face this problem? Was it caused by the installation of latest updates?

After a week of working with Debian, I decided to install the KDE3 version straight from an NetInstall CD. This fixed some issues for me as well as made networking and folder sharring a snap! But now its time to add all the extra packages I need.
Here's the problem: Using any kind of Package Manager yields the same results:
E: Could not get lock /var/lib/dpkg/lock - open (11 Resource temporarily unavailable)
E: Unable to lock the administration directory (var/lib/dpkg/), in another process using it?
RESULT=100
I've tried apt-get from root command line and the KPackage Manager that comes with KDE3 with same results. I have only one user that was created during Debian install. I'm having some other problems, from what I've seen on the net, they all seem to point to not having proper Super User access (I'm guessing here). What could cause this error? AND/OR How do I make sure I have top level access to the configure the system? (I tried logging in as "root", but the login errored out saying that this was not allowed).
I need to create an SSH user that can only access the directory I would specify for them. For example, I've been able to execute the following:
useradd -d /home/me/directory_for_this_user someuser
So when someuser logs in they get into this directory. Problem is that once they log in they can simply execute:
cd /
and navigate through all other directories which is a security risk.
How I could limit someuser's access to only /home/me/directory_for_this_user and its subdirectories and nowhere else in the system?
How to allow access to some commands having root privleges to be run by non root user. I am new to unix/linux and I have a major assignment.
