![]() The example above shows that when we log in as the user guest and start the script with sudo, we must type the password. Therefore, if we execute the same script as another regular user, we have to provide the correct password: guest$ sudo. However, this privilege is only assigned to the user kent. Further, we havenât leaked the password anywhere. rw- 1 root root 19768 Oct 24 22:59 root_vimrcĪs weâve seen in the output, this time, sudo didnât prompt for the password and copied the file directly. See for example Set sudo password differently from login one. This can be altered by policy files such as /etc/sudoers. For example: derek sudo ls /var/log/secret sudo password for derek: audit.log audit.log.1 audit.log.2.Next, letâs save the change and test if it works as we expected: kent$ sudo. Initially running the following, note down the highlighted public ip address then proceed till sudo apt-get update and when password is not matched, type ssh azureuserpublicipaddress, substitute your public ip address noted above then press enter -> Type yes -> sudo apt-get update ->. It is usually your personal login password. This line tells sudo: When the user kent executes the script /tmp/test/cpvimrc.sh with sudo, the sudo command will run the script as root without asking for a password. To achieve that, we can add one line to the sudo commandâs configuration: kent ALL=(root) NOPASSWD: /tmp/test/cpvimrc.sh cpvimrc.shâ command in a non-interactive mode. Our goal is to allow the kent user to run the â sudo. Both of them require root permission to save the changes. This will work even if you are at a desktop manager login screen, and you cannot login to your DM, as the alt-ctl-f2 console does not depend on the GUI at all.To edit the sudo commandâs configuration, we can either execute the visudo command or edit the file /etc/sudoers. Anyway you might need to wait a few minutes or type 'man passwd and look up how to unlock the user from thealt-ctrl-f2` root account. I was locked out of my account for 8 minutes because of fails, but I think this reset that timer. Open a new terminal and test with sudo ls.alt-ctrl-f7 brings you back to your desktop.Execute command passwd USERNAME with your user name substituting for 'USERNAME'.Login as root You need to have root's password, which is not the same as sudo.This does not work in a terminal or via su I am slightly concerned that I have been hacked, but that would be difficult because two firewalls would have to be compromised, and no one in the household would know how to change a passwd but me, so I am assuming that is not the issue, but I changed both user and root passwds as a precaution. My password was the same but when I entered it for sudo it no longer worked. Gksudo xclock was something I was able to get into, no problem. I changed my password with pkexec passwd $USER. Su $USER <- worked for me, however, my password still does not do much (in sense of not working for other things) ![]() Pkexec usermod -a -G admin $USER <- Says admin does not exist Pkexec apt-get -purge -reinstall install sudo (Although, I haven't gone into recovery mode.)Īnd also reinstalled sudo with: pkexec apt-get update I can log in with my password, but it's not accepted as valid for authentication <- That is pretty much my issue. # See sudoers(5) for more information on "#include" directives: # Allow members of group sudo to execute any command ![]() # Members of the admin group may gain root privileges # See the man page for details on how to write a sudoers file.Äefaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin" # Please consider adding local content in /etc/sudoers.d/ instead of # This file MUST be edited with the 'visudo' command as root. As a result, non-root users can enter such commands without logging in to the root user account. System administrators can grant sudo access to allow non-root users to execute administrative commands that are normally reserved for the root user. ![]() (And it was the same ubuntu, ubuntu 12.04 LTS) groupsĪi adm cdrom sudo dip plugdev lpadmin lsb_release -rd A Red Hat training course is available for RHEL 8. Is there some other password (one I'm not aware of) I'm supposed to be using other than my user password? I've had this ubuntu before, on another hard drive and I didn't have this problem. ![]() I'm typing my user password in (not a capslock issue), and for some reason it still says 'Authentication Failure'. Before I mention anything further, DO NOT give me a response saying that terminal won't show password input. ![]()
