Ensure the IP Addresses for Listening for Requests Are Specified

НискаНиво 2Аутоматскаapache

Опис

The Apache Listen directive specifies the IP addresses and port numbers the Apache web server will listen for requests. Rather than be unrestricted to listen on all IP addresses available to the system, the specific IP address or addresses intended should be explicitly specified. Specifically, a Listen directive with no IP address specified, or with an IP address of zeros should not be used. Every Listen directive must name a specific IP address (not just a port, *, 0.0.0.0 or [::]). Reads the main configuration (APACHE_CONF overrides; default /etc/apache2/apache2.conf, /etc/httpd/conf/httpd.conf or /usr/local/apache2/conf/httpd.conf) and every Include/IncludeOptional file.

Очекивани излаз: compliant

Како се исправља

Метод исправке: Смерница или закрпа инфраструктуре

Change each Listen to an explicit address, e.g. Listen 10.20.30.40:80. Then run apachectl configtest and reload Apache.
