NOLOGIN(5)                    File Formats Manual                   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

SEE ALSO
