Linux common command nologin command can politely refuse users to log on to the system and give information at the same time.

Nologin refuses users to log in to the system

Add that if you try to log in as this type of user, add a record in log, and then output This account is currently not available information on the terminal, and that's it. Generally, such an account is set up for the account that starts the service, which only allows the service to start, but cannot log in to the system.

Syntax nologin instance Linux prohibits users from logging in:

After the user is prohibited from logging in, the user cannot log in to the system, but can log in to ftp, SAMBA, and so on. When we do system maintenance under Linux, we hope that individual users or all users can not log on to the system to ensure the normal operation of the system during maintenance. At this time, we will prohibit users from logging in.

1. Prohibit individual users from logging in, such as lynn users.

Passwd-l lynn this means locking out the lynn user so that the user cannot log in.

Passwd-u lynn above is to unlock the locked user lynn, and the user can log in.

2. We modify the shell logged in by the user in the / etc/passwd file

Vi / etc/passwd is changed to:

Lynn:x:500:500::/home/lynn:/sbin/nologin the user will not be able to log in.

3. All users are prohibited from logging in.

Touch / etc/nologin users other than root cannot log in.
