Always get "Error LANrx: invalid DNS section counts: 1 0 0 1, dropped" when using `dig` about fdns HOT 5 OPEN

Bug! Thanks for reporting it.

from fdns.

I'll have to document it in the man page.

dig attaches to the query a DNS cookie in the "additional" section of the packet. We filter out and drop such requests, and we let through only regular queries generated by regular applications. We also drop anything else but A and AAAA requests, so most of the request options dig provides will be filtered out.

When using dig from behind fdns, send the query to a specific server using @server-ip-address on the command line. This way you bypass fdns. For example:

$ dig @9.9.9.9 debian.org

from fdns.

just to remember to document it!

i use dig to test the setup, so a @... is exactly not what i want to do... ;)

do you know a way to tell dig to do request that fdns would not filter out? maybe that should be documented as well?

from fdns.

its not only dig that does it, go seems to suffer from that too:

main.go:29:2: maunium.net/go/[email protected]: Get "https://proxy.golang.org/maunium.net/go/mauflag/@v/v1.0.0.zip": dial tcp: lookup proxy.golang.org on 127.0.0.1:53: read udp 127.0.0.1:48660->127.0.0.1:53: i/o timeout

(with corresponding logs from fdns). why does fdns drop such requests?
