This command was useful back when sudo did not have the -i option, but I think that option has been there for about 15 years by now. This would require giving the user(s) in question at least access to run the ` su - targetuserĬommand as root, and it will be more difficult to piece together from the logs what the user actually did.
To get a shell as the target user, with the exact same environment the target user would get when logging in directly.įor historical reasons, some people reflexively use sudo su - targetuserįor the second purpose. To quickly execute individual commands as the target user, or $ sudo -iu targetuser Then, the user(s) can do $ sudo -u targetuser command
#SUDO VS SU VS SUDO SU FULL#
If you want to give an user (or a group) full access to a specific other user account and nothing else, you can do it this way: user ALL=(targetuser) ALL Meaning: "any members of group wheel on ALL hosts can sudo to ALL user accounts to run ALL commands." So it's exactly the same as your "bad" line: bob ALL=(ALL) ALL When the wheel group membership gives an user full root access through sudo, it is normally configured like this in the /etc/sudoers file: %wheel ALL=(ALL) ALL Do I have to create a group and then add all users to this group or is there another way?
#SUDO VS SU VS SUDO SU HOW TO#
And according to my knowledge bob ALL=ALL ALLīasically makes bob have the same power like root which is not good right.Īnother question I have is how to make all users on the system able to execute the last command. When used with the -i option, sudo run an interactive. Running sudo su - and then typing the user password has the same effect the same as running su - and typing the root password.
sudo bash & sudo sh: Anything after the sudo is a program to run - so in these cases you are asking to run a couple of shells - bash and dash. If you drop the 'userid' it assumes you are trying to login as root - which you can't (unless you change the root password).
If the user is granted with sudo assess, the su command is invoked as root. Normally you would use the format su -Sorry, user bob is not allowed to execute '/sbin/iptables -L' as rootĪnd so am not sure how to give sudo access to the machine to a user if the group wheel is not there. The sudo command allows you to run programs as another user, by default the root user. So can I do the following line then: bob ALL=/usr/bin/sudoīut then I changed to user bob after and tried to execute # sudo iptables -L Not entirely accurate but close enough to remember. I find an easy way to remember which is which is su switch user (to root - yes, you can use it to switch to other users too), sudo switch user to root and do, and chroot as change root. Then how can I grant bob sudo access to the machine.When I did # which sudo almost confusingly, on ubuntu, visudo uses nano.
#SUDO VS SU VS SUDO SU INSTALL#
guix package -i emacs sudo apt-get install emacs sudo. Or let's say there is no wheel group or it is deleted for some reason. Here are some of the commands that various GNU/Linux distributions use to install a package named emacs.
Should I just add the user to the wheel group. When you are asked to give a user sudo access to the machine.
