2.1.1 Ensure chargen services are not enabled (Scored)

Level 1 - Server 
Level 1 - Workstation

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.

Run the following command and verify chargen-dgram and chargen-stream are off or missing:

# chkconfig --list 
xinetd based services: 
  chargen-dgram: off 
  chargen-stream: off

Run the following commands to disable chargen-dgram and chargen-stream:

# chkconfig chargen-dgram off 
# chkconfig chargen-stream off
