Discussion

The daytime service provides the current date and time to other servers on a network. This daytime service is a defunct time service, typically used for testing purposes only. The service should be disabled as it can leave the system vulnerable to DoS ping attacks.

Check Content

From the command prompt, execute the following command: 
# grep "^daytime[[:blank:]]" /etc/inetd.conf

If there is any output from the command, this is a finding.

Fix Text

In "/etc/inetd.conf", comment out the "daytime" entries by running commands: 
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'daytime' -p 'tcp' 
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'daytime' -p 'udp'

Restart inetd:
# refresh -s inetd
