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.

SEE ALSO
     login(1), rlogin(1), telnet(1), nologin(8), shutdown(8)
