NTP
By default,
ntpd
is factory-configured to listen on both IPv4 and IPv6 addresses on all interfaces.
This may be changed by editing
/etc/ntp.conf
and adding the desired
interface
directives to
achieve the desired behavior, and then copying it to
/boot/etc
. For example, adding this line:
interface ignore ipv6
will cause ntpd to not bind to any IPv6 addresses. Refer to the NTP documentation for details on the
interface
directive.
IPv4-Only Protocols
There are several protocols running on RTM3205 which are not IPv6 capable:
telnet
(client and
server),
ftp
and
dhcpcd
. Due to their intrinsic insecurity,
telnet
and
ftp
are rapidly being depre-
cated, and probably have little business running over an IPv6 network. The address autoconfiguration
capabilities of IPv6 along with the Neighbor Discovery Protocol (NDP) make the DHCP protocol less
important in IPv6 networks. The optional PTP/IEEE-1588 protocol is also not available on IPv6.
