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.txtexists, 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
       -i --interactive
       --init-file file
       -i, --interactive

       --rcfile file

              Display help text and exit.

       -V, --version
              Display version information and exit.

NOTES         top

       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
       logging into the system.  pam_nologin(8) functionality is controlled
       by /var/run/nologin or the /etc/nologin file.

HISTORY         top
