[dnsdist] Strip EDNS option on response

Is there a way to configure dnsdist to strip a specified EDNS option (e.g., EDNS, COOKIE, etc.) from an outgoing DNS response? Thanks, Casey ___ dnsdist mailing list dnsdist@mailman.powerdns.com https://mailman.powerdns.com/mailman/listinfo/dnsdist

[dnsdist] Log timestamps

Hello there, I have another question about logging. When I send three DNS queries in a row, all within one second, often the log messages (i.e., with DnstapLogAction("foo", logger)) show that they arrived within the same microsecond. I realize that there is some buffering going on, such that

[dnsdist] High-fidelity timestamp in FrameStream logging

Hi all, I am using the following to log queries: logger = newFrameStreamTcpLogger("127.0.0.1:4343") addAction(AllRule(), DnstapLogAction("foo", logger)) Then I use this command line to read and produce yaml output: fstrm_capture -t protobuf:dnstap.Dnstap -a 127.0.0.1 -p 4343 -w - | dnstap-read

[dnsdist] Add ECS to response

Hello! I'm wondering if it is possible to add an arbitrary ECS value to a response. I've poked around through the docs, but it wasn't immediately clear how that might be done. I did try: addResponseAction(AllRule(), SetECSAction('0.0.0.0/0', '::/0')) But SetECSAction() is only for queries, n

[dnsdist] Logging

Hello! I'm new to dnsdist, and we're setting it up to use for some experimental measurements, so we can use its flexibility to send queries to different backends, based on different options. Our previous setup was almost exclusively BIND, so all of our logging was using BIND's logging mechanis
