Im not possible to unlock screen saver or in TTY where I see (after login attempt): Arch Linux 5-8-3-arch1-1 (tty5) jenpockej login: waldauf The account is locked due to 3 failed logins. After reboot, I see the SDDM login screen. It is common to see ALL or (ALL:ALL) used to allow the user to act as anyone or any group, but in my case this is not necessary, so I have left it blank, which disables -u and -g. Hello, I have trouble log in into my system. I personally don't even have sudo installed, and just use su. Use the following command to edit the /etc/sudoers file: sudo visudo This will open the default text editor (Nano in Ubuntu) for editing this file. Imo, it's better to have one more step between you and the execution of a sudo command. If a user runs a nasty script by accident, that could be a real problem. For my alias, this rule was: ducklord ALL ( ALL. It should look like: USERNAME ALL ( ALL) NOPASSWD:ALL. If there isn't, move to the end of the file and create a new rule there. If there is, change it to what we'll see next.
Arch sudo without password password#
The (RUN_AS_USER:RUN_AS_GROUP) portion of the line can be used to allow the user to run commands as other users or groups with the -u and -g arguments, respectively. From a puristic point of view though, being able to sudo without a password is equivalent to root access, so the only benefit to the privilege separation at that point is that typos are less likely to kill your whole computer. Aside from the sudo password being the user's password and not root's as pointed out already, NOT requesting a password means that scripts run by the user can invoke sudo undetected. To stop sudo from asking you for your password, first, check whether there's an existing rule with your alias. The HOST argument specifies what hosts this rule is valid for - in this case I have chosen the special value ALL to mean that it's valid for all hosts. For sudo there is a -S option for accepting the password from standard input. Adding NOPASSWORD: as part of the command means that they will not be prompted for a password when they call sudo for this particular command. This prevents sudo from creating files with more open permissions than the users umask allows. This says that the USER may use sudo to execute the command COMMAND. Sudo will union the users umask value with its own umask (which defaults to 0022). USER HOST=(RUN_AS_USER:RUN_AS_GROUP) COMMAND
