Package: nginx-extras Version: 1.14.2-2+deb10u3 The description for the package stipulates "Limit Connections, Limit Requests" is a standard module, yet it doesn't seem to be built with the modules:
ngx_http_limit_conn_module ngx_http_limit_req_module Oddly nginx does not complain about unknown directive, but it's does not function correctly and no module files exist for these modules in "/usr/lib/nginx/modules".
