RFC 2136 Dynamic DNS updates. Anyone using them?



  • I've been trying to get dynamic dns working with pfsense 1.0.1 but it doesn't seem to actually run. Running tcpdump on the dns server didn't show any attempts to update. There is a cron job to run the DynDNS client but I didn't find anything for RFC 2136 Dynamic DNS.

    I looked through the code and found the services_dnsupdate_process(); function. When I run that function manually it creates the keys and the nsupdatecmds file in /var/etc.  The nsupdatecmds file doesn't have a server entry to tell nsupdate where to send the update so the update doesn't work.  If I add the server line to nsupdatecmds, then run nsupdate from the command line with the key generated by pfsense and the nsupdatecmds file, the update succeeds.

    It doesn't seem like the code for RFC 2136 Dynamic DNS updates is complete. Am I doing something wrong?
