</div>Not related to ipv6, but if you want a ntp server for your LAN you have to do this:<br>
# opkg remove luci-app-ntpc<br>
# opkg remove ntpclient<br>
# killall ntpclient<br>
# uci set system.ntp.enable_server 1<br>
# uci commit system<br>
# /etc/init.d/sysntpd restart<br>
<br></blockquote><div><br>This is an artifact of formerly using the isc ntp server in cero (for the multicast, and autokey support, as well as for the possible linkage to the gpsd daemon for a 1pps signal) At some future point I'd like to make this work again (because testing against a stratum 1 clock like what gpsd can do has long been on my list of worthwhile things to do), but I have no problem with using the well integrated smaller default ntp server in openwrt. (well, I'd like it to do ipv6, too)<br>
<br>I have made these two packages optional and enabled the local ntp server.<br><br>Still up here, no matter what ntp client/server is used is some means of doing dnssec again.<br> <br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
Otherwise sysntpd will fail to start because ntpclient has already bound the ntp port.<br>
According to <a href="http://wiki.openwrt.org/doc/uci/system" target="_blank">http://wiki.openwrt.org/doc/uci/system</a> busybox ntpd can act both as a client&server so<br>
I think that ntpclient is unnecessary.<br>

<br>
</div>Just one note regarding this comment in your script:<br>
# Append proper configuration commands to /etc/dnsmasq.conf<br>
# This is the proper configuration file: you can ignore both<br>
# /etc/config/dhcp and /var/etc/dnsmasq.conf as they seem not to have any effect<br>
<br>
/var/etc/dnsmasq.conf is overwritten when you '/etc/init.d/dnsmasq restart', thats why it seems to not have an effect.<br>
BTW initially I was doing this:<br>
<br>
# /etc/init.d/dnsmasq stop<br>
# vi /var/etc/dnsmasq.conf<br>
# /usr/sbin/dnsmasq -C /var/etc/dnsmasq.conf -d<br>
....<br>
^C<br>
# vi /var/etc/dnsmasq.conf<br>
# /usr/sbin/dnsmasq -C /var/etc/dnsmasq.conf -d<br>
....<br>
<br>
But after reinstalling dnsmasq-dhcpv6 I realized that just modifying /etc/dnsmasq.conf and restarting dnsmasq worked too<br>
(presumably due to this entry in /var/etc/dnsmasq.conf: conf-file=/etc/dnsmasq.conf).<br>
<br>
