Re: [MirageOS-devel] simple dns server

[Anil Madhavapeddy <anil@xxxxxxxxxx>]

It's not obvious, but that particular zone file came from a regression test of the original OCaml DNS library written in 2006, and so is an odd choice (my fault) for an example zone file!

Feel free to change it around to something a little more accessible.  The other thing missing from the DNS library is a more natural way to add and remove records without going through a zone file, and so that's a good area for improvement.

Now that the TLS stack is up and running, I'm going to move the mirage.io DNS over to a unikernel as well. We used to run the DNS self-hosted, but it has migrated to Gandi recently.  The GitHub workflow is proving to be quite an effective deployment interface, and so we're in good shape to bring back the hosted DNS as well.  It just needs a good logging interface (c.f. the other thread), but for now I'll capture the console output.

Hm, I had this same problem.  I was able to get the server to run by making the following changes to data/test.zone (although the initialization still complains about unknown services in other lines):

on line 55, s/udp/17/

Then, rerun `mirage configure --unix` and `make`.  After doing that and starting the server, I'm able to get a response from `dig @127.0.0.1 ns0.d1.signpo.st.` (127.0.0.1 because I'm running in socket mode).

Cheers,

Hello

I'm trying to get the simple dns server to work that Heidi has in her examples (github.com/heidi-ann/ocaml-dns-examples) and I'm getting an error which I don't really understand - it's occurs both on the cubieboard and my amd64 desktop:

Does anyone have any idea how I can move forward on this?

Thanks
