![]() ![]() So a bit of experimentation will be needed -). ![]() For reference, I'm leaving my previous answer: If you add a line of the form wheel ALL (ALL) NOPASSWD: ALL to /etc/sudoers (using the visudo command, of course), it will let everyone in the group wheel run any commands without providing a password. So I suspect is a matter of finding all the occurences of pam_unix.so in the files above, and add the option nullok (or change the nullok_secure to nullok) to the entries.Īccording to this post the file should be /etc/pam.d/common-auth - but I am not sure about this because in Ubuntu the VC are in the /etc/securetty list so the null password for root should work from there (although not from a terminal emulator), and the SO states it doesn't work. to allow all users to run all commands without a password. Set to one of the values found in /etc/securetty. Password to access the service as long as the value of PAM_TTY is To a service if their official password is blank. The nullokĪrgument overrides this default and allows any user with a blank To a service if their official password is blank. Initially, my only change to the sudoers file ( /etc/sudoers) was one line, a user specification that should have enabled nicholsonjf to run all commands with sudo without having to enter a password (see the line that starts with nicholsonjf): This file MUST be edited with the 'visudo' command as root. The default action of this module is to not permit the user access ![]() 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. Now, the module that check for the passwords "unix style" is pam_unix.so, in which man page you can find among the options: nullok A Red Hat training course is available for RHEL 8. In /etc/pam.d there are all the PAM configuration files that tell the system how to do the authentication of users. I think this is a PAM thing (PAM= pluggable authentication modules). Warning not tested because I think it's not such a great idea, even for a VM (bad habits are difficult to remove.). ![]()
