Chat over dns!

You can send messages to other people in a place where everything is blocked except for dns. The app sends all the traffic over dns. Client sends the message in domain labels. Server responds back with records.

Binds to 0.0.0.0:53 (requires privileges to bind the well-known port). Use a high port for local testing:

cargo run -p server -- --port 5354

The server writes structured JSON to stdout. Export them for lnav with:

journalctl -u igloo-server --output=json | lnav
# or
journalctl -u igloo-server --output=json -f | lnav

journalctl -u igloo-server --output=json > server.log
lnav server.log

Query logs directly from journald, or fetch from a remote server first:

# read from journald (default)
bin/logs.py
bin/logs.py latency

# fetch from remote, then query locally
ssh -i ~/.ssh/my_key user@server 'journalctl -u igloo-server --output=json' > /tmp/igloo.log
bin/logs.py /tmp/igloo.log
bin/logs.py /tmp/igloo.log latency

Available queries: errors latency throughput drops by_kind top_talkers top_errors

Client is vibe coded until I get time to do it.

See build/ directory for build instructions.

cargo run -p igloo

# debug mode connects to local igloo server.
# shows DebugPanel
cargo run -p igloo -- --debug

cargo run -p client-dioxus

You can install the Dioxus CLI and use hot reload:

cargo install dioxus-cli
dx serve --package client-dioxus --platform desktop

Sends a signup request to a resolver. Defaults to --domain limoo.lol and --resolver 1.1.1.1:53:

cargo run -p client
cargo run -p client -- --domain limoo.lol --resolver 127.0.0.1:5353

The DNS server the app uses is configurable from the Settings screen. There is also an option to detect your system's DNS resolver and use that.
