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 status returned by nologin is always 1.

OPTIONS

-c, --command command

--init-file

-i --interactive

--init-file file

-i, --interactive

-l, --login

-r, --restricted

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

-h, --help

-V, --version
    Print version and exit.

NOTES

nologin is a per-account way to disable login (usually used for system accounts like http or ftp). nologin 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 logging into the system. pam_nologin(8) functionality is controlled by /var/run/nologin or the /etc/nologin file.

HISTORY

The nologin command appeared in 4.4BSD.
