## README

# 跨平台TCP测试终端 netTool

## 开发初衷
在windows平台上有很多的TCP测试工具，非常方便。有一天，需要在linux测试一个端口是否正常打开时，没有找到合适的工具，搜索也没有发现。于是想开发一个测试工具。

## 开发环境
vs2026
.net 10.0

打包

dotnet publish "nettool/nettool.csproj" -r linux-x64 --self-contained true -c Release -o "d:/mygitee/nettool/nettool/bin/release/net8.0/publish/linux-x64" /p:PublishSingleFile=true

# linux下载

wget https://gitee.com/bonn_admin/net-tool/releases/download/v1.0.0/netTool  && chmod +x netTool 



## 命令示例
```bash
./netTool
./netTool localIp=0.0.0.0 port=10003
./netTool port=20001
./netTool port=20001 echo=true
./netTool type=tcpServer port=20001 echo=true
./netTool type=tcpServer port=20001 respData=hello
./netTool type=tcpServer port=20001 respData=0x010203
./netTool help

# 其他工具示例

## socat

如果没有安装，则先安装

```bash
sudo apt install socat      # Debian/Ubuntu
sudo yum install socat      # CentOS/RHEL
```

侦听8080端口
```bash
bonn@bonnTest:~/桌面$ socat TCP-LISTEN:8080,fork STDOUT
2026/01/26 15:27:39 socat[3048] W address is opened in read-write mode but only supports write-only
I am Client TestI am Client Test
```

socat - tcp-listen:1234,fork 	#STDIO TCP	服务端监听1234端口
socat - tcp:127.0.0.1:1234		#STDIO TCP	客户端连接1234端口

socat - udp4-listen:1234,bind=192.168.56.20,fork	#STDIO UDP	服务端仅监听192.168.56.20接口的1234端口
socat - udp4:192.168.56.20:1234						#STDIO UDP	客户端连接1234端口



socat可以创建虚拟串口
创建两个可以相互通信的 Linux 虚拟串口
socat -d -d PTY PTY


## nc

```bash
bonn@bonnTest:~/桌面$ nc -l -p 8080
