## Description
|
|
|
|
Implement the server's main accept loop and configuration. This ties together the transport acceptor, server handler, rate limiting, and logging into a coherent server process.
|
|
|
|
`ServeOptions` is the programmatic configuration struct (ADR-011) for the server. The accept loop:
|
|
1. Binds a `TransportAcceptor` based on transport mode
|
|
2. Accepts incoming connections (respecting rate limits)
|
|
3. Creates a `ServerHandler` per connection
|
|
4. Passes the stream to `russh::server::run_stream()`
|
|
5. Handles graceful shutdown on SIGTERM/SIGINT
|
|
|
|
## Acceptance Criteria
|
|
|
|
- [ ] `crates/wraith-core/src/server/mod.rs` re-exports all server components
|
|
- [ ] `ServeOptions` struct with fields matching server.md CLI interface: `key`, `authorized_keys`, `cert_authority`, `transport_mode`, `listen_addr`, `tls_cert`, `tls_key`, `acme_domain`, `stealth`, `proxy`, `iroh_relay`, `max_connections_per_ip`, `max_auth_attempts`
|
|
- [ ] `Server::new(opts: ServeOptions) -> Result<Server>` — creates server with bound acceptor, auth config, rate limiter
|
|
- [ ] `Server::run()` — enters accept loop, for each connection: check rate limit → create handler → `run_stream()`
|
|
- [ ] Stealth mode integration: if enabled, protocol detection before `run_stream()`
|
|
- [ ] Graceful shutdown: `Server::shutdown()` method and signal handler (SIGTERM/SIGINT)
|
|
- Stop accepting new connections
|
|
- Send SSH disconnect to active sessions
|
|
- Wait for drain timeout (~2 seconds per session)
|
|
- Forcibly terminate remaining connections
|
|
- [ ] iroh mode: prints endpoint ID on startup
|
|
- [ ] `ServeOptions::key` and `ServeOptions::authorized_keys` accept `KeySource` (file or in-memory)
|
|
- [ ] Integration test: start server, client connects via mock transport, session works, shutdown completes
