    Help with dnsextd and BIND on Ubuntu


    Hello.
    I currently have Ubuntu 12.04 Server running BIND 9.8.1. It is a simple dynamic dns server setup for testing and there is no encryption key involved. Everything appears to be working. I am able to dynamically update the DNS using nsupdate from a client machine and verify that the records were added using dig.

    I am attempting to install the dnsextd so that it can support Long Lived Queries (DNS-LLQ). I reconfigured bind to listen on port 5030 and to allow-updates from 127.0.0.1 (previously set to any). After restarting bind and starting dnsextd, I can no longer dynamically update dns records using nsupdate. I get an update failed: REFUSED.

    I've also tried changing allow-updates back to any but I get the same problem.

    I was hoping if anyone here has any experience successfully setting up dnsextd on linux.

    Let me know if you need any additional information.

    Thanks

    Hey all.
    I narrowed down my problem. I'm getting the output error in dnsextd when attempting to dyamically add a record with nsupdate

    "Rejecting Update Request with 1 additions but no lease".

    Looking at the code, it seems like a lease time is not defined when doing dynamic updating. Is there additional settings for bind/dnsextd that I need to set some default lease time? Or is there another parameter I need to specify when doing the dynamic updating?
    I'll continue to investigate but if anyone has come across this before, let me know.
    thanks!
