NAME
nologin - message displayed to users attempting to log on in the process of a system shutdown SYNOPSIS
/etc/nologin DESCRIPTION
The /etc/nologin file contains the message displayed to users attempting to log on to a machine in the process of being shutdown. After displaying the contents of the nologin file, the login procedure terminates, preventing the user from logging onto the machine. This procedure is preferable to terminating a user's session by shutdown shortly after the user has logged on. Logins by super-user are not affected by this procedure. The message contained in the nologin file is editable by super-user. A typical nologin file contains a message similar to: NO LOGINS: System going down in 10 minutes. SEE ALSO
login(1), rlogin(1), telnet(1), shutdown(1M) SunOS 5.11 21 Dec 1995 nologin(4)

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 SEE ALSO
login(1), ftpd(8), nologin(8), rshd(8), shutdown(8), sshd(8) BSD
