NOLOGIN(5)

NAME
nologin - file disallowing and containing reason for disallowing logins

DESCRIPTION
The file /etc/nologin, if it exists, causes the login procedure, used by programs such as login(1), to terminate. The program may display the contents of /etc/nologin to the user before exiting.

This file is a simple mechanism to temporarily prevent incoming logins. As such, the file /etc/nologin is created by shutdown(8) five minutes before system shutdown, or immediately if shutdown is in less than five minutes. The file /etc/nologin is removed just before shutdown(8) exits.

To disable logins on a per-account basis, see nologin(8).

The file /etc/nologin has no effect on the login procedure for the root user.

FILES
/etc/nologin
    The nologin file resides in /etc.

EXAMPLES

    NO LOGINS: System going down at 18:22
