Discussion

This is the remote WHO service. To prevent remote attacks this daemon should not be enabled unless there is no alternative.

Check Content

From the command prompt, execute the following command: 
# grep "^start[[:blank:]]/usr/sbin/rwhod" /etc/rc.tcpip

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

Fix Text

In "/etc/rc.tcpip", comment out the "rwhod" entry by running command: 
# chrctcp -d rwhod
