, this function is very useful. even if the root user forgets to log out of the system when he leaves the system, it will not be snooped into the system by other users who can access the keyboard. Because after the ticket expires, the system must log on again. Therefore, we recommend that you set the validity period to a shorter value, for example, the default validity period is five minutes. The ticket checking system can also be used to clear users' ticket files. ◆ Centralized management of mu

Article Title: Sudo is related to the Root account in Ubuntu. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In Ubuntu, the traditional UNIX 'root' is blocked (that is, you cannot use root to log on). The reason for this is described later in this article. 　　Quick answe

common user cannot change the password of other users except his or her own password. However, if you change to the root identity to execute the command, you can change the password of other users; For example, if you have a user named linuxsir in the system, we want to change the password of the user, [Beinan @ localhost ~] $ Passwd linuxsir Note: Do not run passwd directly through sudo to change the password of the linuxsir user;Passwd: only root

Sudo (substitute user [or Superuser] do) is a program that is used for UNIX-based systems such as Bsd,mac OS X, and Gnu/linux to allow the user to use a special limited-travel style (usually a super-user) in a way that is safe for users. Prior to Sudo being out 1980 years ago, the general user managed the system by using the Su-cut super-user. But one of the shor

For example: Run some commands like Mount,halt,su, or edit some system configuration files, such as/etc/mtab,/etc/samba/smb.conf. In this way, it not only reduces the number of login and management time of root users, but also improves the security of the system.I. The characteristics of sudo Sudo's role has doomed it to be extra cautious about security, or it could cause illegal users to grab root. At the same time, it also needs to take into accoun
