NOLOGIN(8)                System Administration               NOLOGIN(8)

NAME         top

       nologin - politely refuse a login

SYNOPSIS         top

       nologin [-V] [-h]

DESCRIPTION         top

       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         top

       -c, --command command

       -V, --version
           Print version and exit.

NOTES         top

       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         top

       The nologin command appeared in 4.4BSD.
