NOLOGIN(8) System Administration NOLOGIN(8)NAMEnologin - politely refuse a login
SYNOPSISnologin [-V] [-h]
DESCRIPTIONnologin 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 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-h, --help
Display help text and exit.
-V, --version
Display version information and exit.
NOTESnologin is per-account way to disable login (usually used for system
accounts like http or ftp). nologin(8) uses /etc/nologin.txt as
optional source for non-default message, the login access is always
refused independently on 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 /etc/nologin file.
