Currently, we are sending each ICE candidate individually from the client to the gateway and vice versa. This causes a slight delay as to when each ICE candidate gets added on the remote ICE agent. As a result, they all start being tested with a slight offset which causes "endpoint hopping" whenever a connection expires as they expire just after each other. In addition, sending multiple messages to the portal causes unnecessary load when establishing connections. Finally, with #5283 we started **not** adding the server-reflexive candidate to the local ICE agent. Because we talk to multiple relays, we detect the same server-reflexive candidate multiple times if we are behind a non-symmetric NAT. Not adding the server-reflexive candidate to the ICE agent mitigated our de-duplication strategy here which means we currently send the same candidate multiple times to a peer, causing additional, unnecessary load. All of this can be mitigated by batching together all our ICE candidates together into one message. Resolves: #3978.
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.
