If the -A ( askpass) option isspecified, a (possibly graphical) helper program is executedto read the user's password and output the password to thestandard output. A' Normally, if sudo requires a password, it will read itfrom the user's terminal. If an I/O plugin is configured, the running command's input and output may be Security policies may log successful and failed attempts to use sudo. When invoked as sudoedit, the -e option (described below), is implied. The cached credentials without running a command.

By running sudo with the -v option, a user can update Sudoers policy caches credentials for 5 minutes, unless overridden in sudoers(5). Security policies may support credential caching to allow the user to run sudo again for a period of time without requiring authentication. This limit is policy-specific the default password prompt timeout for the sudoers security policy is 5 minutes. If authentication is required, sudo will exit if the user's password is not entered within a configurable Password or another authentication mechanism.

The policy may require that users authenticate themselves with a The security policy determines what privileges, if any, a user has to run sudo. See the PLUGINS section for more information. The default security policy is sudoers, which is configured via the file Logging plugins to work seamlessly with the sudo front end. Third parties can develop and distribute their own policy and I/O Sudo supports a plugin architecture for security policies and input/output logging. Sudo allows a permitted user to execute a command as the superuser or another user, as specified by the security policy.

Note: As mentioned, you may need to use adm as your admin group name, depending on which version of Ubuntu is being used.Īs I was researching this, I realized that there's a line in the /etc/sudoers file that is not a comment, but a directive that makes any file or folder under the directory /etc/sudoers/* override the contents of /etc/sudoers. You can also add the default AWS ubuntu user to the admin group via this command: sudo usermod ubuntu -g admin (on older versions of ubuntu, you may need to): sudo service sudo restartĮdit: You may have to add the admin group as I don't think it exists by default. Then for every user that needs sudo access WITH a password: sudo adduser sudoĪnd for every user that needs sudo access WITH NO password: sudo adduser admin # See sudoers(5) for more information on "#include" directives: # Members of the admin group may gain root privileges # Allow members of group sudo to execute any command

I found that the most straight forward thing to do, in order to easily replicate this behavior across multiple servers, was the following: sudo visudoĬhange this line: # Members of the admin group may gain root privileges
