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