Currently, we simply drop a DNS query if we can't fulfill it. Because DNS is based on UDP which is unreliable, a downstream system will re-send a DNS query if it doesn't receive an answer within a certain timeout window. Instead of dropping queries, we now reply with `SERVFAIL`, indicating to the client that we can't fulfill that DNS query. The intent is that this will stop any kind of automated retry-loop and surface an error to the user.

Rust development guide
Firezone uses Rust for all data plane components. This directory contains the Linux and Windows clients, and low-level networking implementations related to STUN/TURN.
We target the last stable release of Rust using rust-toolchain.toml.
If you are using rustup, that is automatically handled for you.
Otherwise, ensure you have the latest stable version of Rust installed.
Reading Client logs
The Client logs are written as JSONL for machine-readability.
To make them more human-friendly, pipe them through jq like this:
cd path/to/logs # e.g. `$HOME/.cache/dev.firezone.client/data/logs` on Linux
cat *.log | jq -r '"\(.time) \(.severity) \(.message)"'
Resulting in, e.g.
2024-04-01T18:25:47.237661392Z INFO started log
2024-04-01T18:25:47.238193266Z INFO GIT_VERSION = 1.0.0-pre.11-35-gcc0d43531
