Extracted out of #5797. This is a problem that becomes evident as https://github.com/firezone/firezone/issues/2667 is implemented: Whenever connlib sees a DNS packet where the sentinel DNS is a resource, it's forwarded to the resource instead of requests being resolved locally. This doesn't work well with system's DNS servers since many times those are provided by the DHCP to be a local resolver which can't be reached from a gateway. Meaning that with full route this request will be just dropped. Preventing all internet connections outside of Firezone. Most of the times when an administrator actually wants to forward all DNS request they will add explicitly an upstream DNS server which makes sense since depending on what the local DHCP configures isn't a good idea if you want to tunnel DNS requests. This makes this behavior explicit and docs and UI should be updated accordingly. Co-authored-by: Gabi <gabrielalejandro7@gmail.com> --------- Co-authored-by: Gabi <gabrielalejandro7@gmail.com>
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.

2024-04-01T18:25:47.238193266Z INFO GIT_VERSION = 1.0.0-pre.11-35-gcc0d43531
