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 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
