Discussion

This is the Neighbor Discovery Protocol (NDP) daemon, required in IPv6. The ndpd-host is the NDP daemon for the server. Unless the server utilizes IPv6, this is not required and should be disabled to prevent attacks.

Check Content

If the system is using IPv6, this is Not Applicable.

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

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

Fix Text

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