Hello
I have a use case for updating a dynamic IPv6 address for the mob1s1a1 interface. Since it is behind CGNAT, the V6 remains externally accessible and is a good way to remotely connect with the device. I previously used a custom script to update my DNS server (BIND) using TSIG key.
I don’t see any example of how to configure the bind-nsupdate method in the builtin Dynamic DNS config area. Is it documented anywhere?
Hello,
I use a direct freedns.afraid.org entry and a crontabs command for that:
15 3 * * * sleep 14; curl https://v6.sync.afraid.org/u/xxxxxxxx/
xxxxxxxx is the key assigned when you register a free name.
Works fine.
Regards,
Thanks as always @flebourse for your tips. I didn’t want to rely on another 3rd party (I already have my own BIND infra set up) so I just went back to my hand-rolled script + crontab.
At some point nsupdate was removed from the base RUTOS build so I did have to opkg -e /etc/opkg/openwrt/distfeeds.conf install ddns-scripts-nsupdate --force-overwrite (yes the force was needed for some reason…)
A little hairy but all good for now.
I noticed that there is a preinstalled package named ddns-scripts_nsupdate which conflicts with the needed ddns-scripts-nsupdate package (note the subtle difference: _ vs -).
The conflicting file is /usr/lib/ddns/update_nsupdate.sh
This should be corrected (or better yet, put nsupdate back in the base build, since out of the box the rfc2136 dyndns update choice is completely non-functional, with no visual indication of such)
