echo is a network service that responds to clients with the data sent to it by the client. 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.
Ensure the echo services are not enabled:
grep ^echo /etc/inetd.conf
No results should be returned.
Remove or comment out any echo lines in /etc/inetd.conf:
sed -i 's/^echo/#echo/' /etc/inetd.conf
Not enabled by default on Ubuntu 12.04 LTS Server.
