And in cloudinit file you can specify all users to be created and you can give them passwordless sudo. #includedir setting NOPASSWD:, still I have to enter the password. multipass supports cloud-init and with it you can do all those things automatically without any script. # 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.ĭefaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin" # Please consider adding local content in /etc/sudoers.d/ instead of # This file MUST be edited with the 'visudo' command as root. How can I fix that in order to run passwordless sudo commands for the test user. ^ This blocks access to console for anyone who is not a member of system or root.I have added a username to the sudoer file, but as you can see below, when I run sudo ls I have to enter the password. If safety is your concern, then your concern should be directed towards remote/code threats versus someone actually touching your computer when you leave the room!!!įood for paranoia(dont type this one in just review it): sudo sed -i 's/#-:ALL EXCEPT (wheel) shutdown sync:LOCAL/-:ALL EXCEPT (wheel) shutdown sync:LOCAL/g' /etc/security/nf "/etc/security/nf" has the layout for access control via tcp/ip(192.168.0.1) communication and through telnet services (tty1&tty2&tt圓.etc) This allows more precise filtering per application via transport protocol. Superuser authentication uses the same pam.d procedure as all other login authentications. There are a lot of checks/balances that 'su' authentication must go through. The second/third commands allows all members of group "root" to be superuser without a password, versus only allowing the user "root" su privileges for authentications.ĭon't mess around with /etc/sudoers. *The first command adds your %username% to the group "root" Goto line 19 and remove the "#" before # auth sufficient pam_wheel.so trust (may be a different line number for some) sudo sed -i 's/# auth sufficient pam_wheel.so trust/auth sufficient pam_wheel.so trust/g' /etc/pam.d/su` Step 1: Open up a terminal window and then type " sudo usermod -a -G root %username%" %username& is the global variable for your username(replace it with desired username) You can read my security concern/solution for this procedure at the later part of this post. Just enter your password a couple times and then you'll never have to enter it again! This will allow you to add a local admin account to the group "root" which is then un-commented from a template which will allow the entire group "root" superuser privileges. Now for the simple answer! No possible way to mess anything up or fudge your install up. It may be advantageous to only give password free access for certain commands. Sudo is designed to give users just enough access to do their job without the need to expose your entire system. You should really read the documentation. This will help prevent breaking sudo completely. If you have multiple users on your system, or if this is a file server, all users files could be at risk as root can do anything!Īlso, if you make a mistake, visudo will output and error message and not save changes to the file. Keep in mind that anyone who has access to your terminal while you are logged in - or if you have ssh setup for key-based auth, or (even worse) have enabled password free session logins - complete and unfettered access to your entire system. If all goes well, and you are a member of the steroid_users group, you will be able to issue sudo *some-command* without the bother of needing to enter your password. To the end of the file, exit, and save the file. For example, if you wanted to give everyone in the steroid_users group root privileges without the need for a password for all commands you would add: %steroid_users ALL=(ALL) NOPASSWD: ALL You will need to decide who you want to give access to it could be ALL for everyone (a very bad idea), a user, or a system group. nano is generally thought to be the easiest to use, but pick the editor you are most comfortable/familiar with. If this is the first time that you have run visudo, it will ask you which editor you prefer. The short answer is run sudo visudo in a terminal. This is thoroughly explained in the documentation. The real answer to this question can be complicated because sudo is very powerful, and can be configured to do cool things.
