The stdio listener wraps os.Stdin/os.Stdout as a net.Listener that accepts exactly one connection. It enables GOST to be used as an SSH ProxyCommand, where the parent process (SSH) pipes the transport byte stream through the child process's standard I/O. Usage: gost -L stdio://example.com:22 -F http://proxy:8080 The URL host:port is treated as the forwarding target and converted to a forward node in buildServiceConfig. The standard forward handler then routes traffic through the configured chain to the destination. Fixes go-gost/gost#433
x
The implementation layer for the GOST proxy framework. Every interface defined in core/ is implemented here — handlers, listeners, dialers, connectors, plus config parsing, registries, and all cross-cutting concerns.
Package layout
| Directory | Purpose |
|---|---|
handler/ |
Protocol handlers (http, socks4/5, ss, ssh, tunnel, tun, dns, redirect, etc.) |
listener/ |
Protocol listeners (tcp, tls, ws, http2/3, quic, kcp, icmp, tun, udp, etc.) |
dialer/ |
Outbound dialers (tcp, tls, ws, http2/3, quic, grpc, ssh, wg, kcp, icmp, etc.) |
connector/ |
Destination connectors (http, socks4/5, ss, ssh, relay, tunnel, direct, etc.) |
config/ |
Config struct, YAML/JSON parsing, and service construction |
registry/ |
Typed global registries for all component types |
service/ |
Accept loop wiring listener + handler |
chain/ |
Multi-hop forwarding chain and route implementation |
router/ |
Route table router (destination-based routing) |
hop/ |
Node group with load-balanced selection |
selector/ |
Load-balancing strategies (round-robin, random, weighted, hash) |
auth/, bypass/, admission/ |
Authentication, bypass rules, admission control |
resolver/, hosts/ |
DNS resolution and host mapping |
limiter/ |
Traffic, connection, and rate limiters |
recorder/, observer/ |
Traffic recording and observability |
ingress/, sd/, routing/ |
Ingress control, service discovery, routing rules |
logger/, metrics/, api/ |
Logging, Prometheus metrics, Web API |
metadata/, ctx/ |
Metadata key-value system and context propagation |
internal/ |
Shared internals — not importable externally |
Component pattern
Every handler, listener, dialer, and connector follows the same pattern: init() registers a constructor into a global registry, the constructor takes functional options, and Init(metadata.Metadata) extracts typed configuration from the metadata key-value map.
