Discussion

The rwalld service allows remote users to broadcast system wide messages. The service runs as root and should be disabled unless absolutely necessary to prevent attacks.

Check Content

From the command prompt, execute the following command: 
# grep "^rwalld[[: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 "rwalld" entry by running command: 
# chsubserver -r inetd -C /etc/inetd.conf -d -v 'rwalld' -p 'udp'

Restart inetd:
# refresh -s inetd
