NOLOGIN(5) BSD 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 min-
utes 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 affect 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
