NAME

6       nologin - politely refuse a login
7

SYNOPSIS

9       nologin [-V] [-h]
10

DESCRIPTION

12       nologin displays a message that an account is not available and exits
13       non-zero. It is intended as a replacement shell field to deny login
14       access to an account.
15
16       If the file /etc/nologin.txt exists, nologin displays its contents to
17       the user instead of the default message.
18
19       The exit status returned by nologin is always 1.

NOTES

53       nologin is a per-account way to disable login (usually used for system
54       accounts like http or ftp). nologin uses /etc/nologin.txt as an
55       optional source for a non-default message, the login access is always
56       refused independently of the file.
57
58       pam_nologin(8) PAM module usually prevents all non-root users from
59       logging into the system. pam_nologin(8) functionality is controlled by
60       /var/run/nologin or the /etc/nologin file.
