nologin
— disallow
logins
Programs such as login(1)
disallow logins if the nologin
file exists. The
programs display the contents of nologin
to the user
if possible and interrupt the login sequence. This makes it simple to
temporarily prevent incoming logins systemwide.
To disable logins on a per-account basis, investigate nologin(8).
The nologin
file is ignored for user root
by default.
The nologin
feature is implemented through
login.conf(5), which allows to
change the pathname of the file and to extend the list of users exempt from
temporary login restriction.
PAM-aware programs can be selectively configured to respect
nologin
using the
pam_nologin(8) module via
pam.conf(5).
The nologin
file will be removed at system
boot if it resides in /var/run and
cleanvar_enable is set to
“YES
” in
rc.conf(5), which is default.
Therefore system reboot can effectively re-enable logins.
