Information
This entry starts the sprayd daemon when required. This service is used as a tool to generate UDP packets for testing and diagnosing network problems.
The sprayd service is used as a tool to generate UDP packets for testing and diagnosing network problems. The service must be disabled if you are not running NFS, as it can be used by attackers in a Distributed Denial of Service (DDoS) attack.
Solution
In /etc/inetd.conf, comment out the sprayd entry-
chsubserver -r inetd -C /etc/inetd.conf -d -v 'sprayd' -p 'udp'
