The ndpd-router must be disabled on AIX.

This manages the Neighbor Discovery Protocol (NDP) for non-kernel activities, required in IPv6.

The ndpd-router manages NDP for non-kernel activities. Unless the server utilizes IPv6, this is not required and should be disabled to prevent attacks.

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

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

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