Wildcard DNS records not working #53

Open negatethis opened 5 months ago

negatethis commented 5 months ago

I've setup leng on NixOS through the provided flake.nix with customdnsrecords = [ "*.nixos.container. IN A 192.168.0.76" ]; thinking it would provide the appropriate DNS mappings. However, leng interprets the wildcard literally, so only *.nixos.container gets mapped to 192.168.0.76, not nixos.container and any subdomains.

Thank you for your report! What you expect is indeed zonefille syntax as per RFC5492. The lib I use (https://github.com/miekg/dns) claims to be compliant to this RFC so might be a bug on my end. I will investigate and hopefully fix it over the next few days

I filed an issue upstream https://github.com/miekg/dns/issues/1534

In the meantime, if you set customdnsrecords = [ "nixos.container. IN A 192.168.0.76" ];

that should get you what you want (but you are still correct that what you posted should work)

An update: I have submitted a PR https://github.com/miekg/dns/pull/1536 upstream (which should fix your case)

Perfect, thank you for looking into it so quickly! I'll keep an eye out for when that PR gets merged upstreamed and used in leng.
