Information
chargen is a network service that responds with 0 to 512 ASCII characters for each connection it receives. This service is intended for debugging and testing purposes. It is recommended that this service be disabled. Disabling this service will reduce the remote attack surface of the system.
Solution
Comment out or remove any lines starting with chargen from /etc/inetd.conf and /etc/inetd.d/*. Set disable = yes on all chargen services in /etc/xinetd.conf and /etc/xinetd.d/*.
