NAME
nologin -- disallow logins
DESCRIPTION
Programs such as login(1) disallow logins if the file /var/run/nologin
exists. Programs display the contents of /var/run/nologin to the user
and exit. This makes it simple to temporarily prevent incoming logins
systemwide.
To disable logins on a per-account basis, investigate nologin(8).
SECURITY
Ignored by login(1) for user root.
FILES
/var/run/nologin The nologin file resides in /var/run.
