# OmniSocketGo

Linux only. Go 1.22.

如果目标机器只运行 `server`，只需要编译并拷贝 `server` 二进制。
如果目标机器只运行 `peer`，只需要编译并拷贝 `peer` 二进制。

`go build ./cmd/server` 和 `go build ./cmd/peer` 会把各自依赖到的功能一起编译进最终二进制，不需要再单独编译 `cmd/internal/...` 包。

- `server` 二进制会包含它依赖到的转发、协议、传输等代码
- `peer` 二进制会包含它依赖到的注册、交互发送、接收落盘、协议、传输等代码
- 只有没有被这个可执行程序引用的其他命令，才不在该二进制里，比如 `cmd/latencysummary`

## Build

按目标架构分别编译。
  mkdir -p bin
  go build -o bin/server ./cmd/server
  go build -o bin/peer ./cmd/peer
  go build -o bin/latencysummary ./cmd/latencysummary

### Linux amd64

```bash
CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build -o bin/server-linux-amd64 ./cmd/server
```

### Linux arm64

```bash
CGO_ENABLED=0 GOOS=linux GOARCH=arm64 go build -o bin/peer-linux-arm64 ./cmd/peer
```

### Linux armv7

```bash
CGO_ENABLED=0 GOOS=linux GOARCH=arm GOARM=7 go build -o bin/server-linux-armv7 ./cmd/server
CGO_ENABLED=0 GOOS=linux GOARCH=arm GOARM=7 go build -o bin/peer-linux-armv7 ./cmd/peer
```



## Run On Different Machines

`server D` 所在机器监听 `0.0.0.0:10909`。

```bash
go run cmd/kcpserver/ -listen 0.0.0.0:10909
-kcp-ts-debug-log logs/d-kcp-ts.jsonl -kcp-session-stats-log logs/d-kcp-stats.jsonl
```

`relay server C` 所在机器

```bash
go run ./cmd/kcpserver/ -mode=relay -listen 0.0.0.0:10909 -relay-remote 172.21.0.13:10909

2>&1 | tee logs/c.stdout.log
```

### peer-a (A)

```bash
go run ./cmd/kcppeer/ -id peer-a -server 172.21.0.13:10909 -relay-via 139.199.57.110:10909 -inbox-dir inbox/a

-latency-log logs/a-latency.jsonl -kcp-ts-debug-log logs/a-kcp-ts.jsonl -kcp-session-stats-log logs/a-kcp-stats.jsonl

go run ./cmd/kcpping/ -id peer-a -server 139.199.57.110:10909 -echo
```

### peer-b (B)

```bash
go run ./cmd/kcppeer/ -id peer-b -server 152.136.164.246:10909 -inbox-dir inbox/b

-latency-log logs/b-latency.jsonl -kcp-ts-debug-log logs/b-kcp-ts.jsonl -kcp-session-stats-log logs/b-kcp-stats.jsonl

go run ./cmd/kcpping -id peer-b -server 152.136.164.246:10909 -to peer-a -count 20 -interval 100ms
```

## Interactive Commands

`peer` 启动后可以在终端里持续使用同一条长连接发送多次消息。

```text
help
text peer-b hello
text peer-a hi
file peer-a /tmp/test125.bin
file peer-a /tmp/test5.bin
quit
```
