NOLOGIN(8) System Administration NOLOGIN(8)
NAME
nologin - politely refuse a login
SYNOPSIS
nologin [-V] [-h]
DESCRIPTION
nologin displays a message that an account is not available and exits
non-zero. It is intended as a replacement shell field to deny login
access to an account.
If the file /etc/nologin.txt exists, nologin displays its contents to
the user instead of the default message.
The exit code returned by nologin is always 1.
OPTIONS

--init-file
-i --interactive
--init-file file
-i, --interactive
-l, --login
--noprofile

These shell command-line options are ignored to avoid nologin
error.
-h, --help

-V, --version
Display version information and exit.
NOTES
nologin is a per-account way to disable login (usually used for system
accounts like http or ftp). nologin(8) uses /etc/nologin.txt as an
optional source for a non-default message, the login access is always
refused independently of the file.
pam_nologin(8) PAM module usually prevents all non-root users from log-
ging into the system. pam_nologin(8) functionality is controlled by
/var/run/nologin or the /etc/nologin file.
