Description
The sprayd service is used as a tool to generate UDP packets for testing and diagnosing network problems. The service must be disabled if NFS is not in use, as it can be used by attackers in a Distributed Denial of Service (DDoS) attack.
ℹ️ Check
From the command prompt, execute the following command:
# grep "^sprayd[[:blank:]]" /etc/inetd.conf
If there is any output from the command, this is a finding.
✔️ Fix
In "/etc/inetd.conf", comment out the "sprayd" entry by running command:
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'sprayd' -p 'udp'
Restart inetd:
# refresh -s inetd
