Ensure ndpd-router is not in use

SedangLevel 1Otomatisaix

Deskripsi

This entry starts ndpd-router on system startup. This manages the Neighbor Discovery Protocol (NDP) for non kernel activities. It receives Router Solicitations and sends Router Advertisements. It can also exchange routing information using the RIPng protocol. The ndpd-router manages NDP for non-kernel activities. Unless the server utilizes IPv6, this is not required and should be disabled. Audit: the ndpd-router start line in /etc/rc.tcpip must be commented out and the ndpd-router subsystem must not be active.
