NAT 内网穿透工具
服务端介绍
1. 如何使用
1.1. 基本使用
git clone https://github.com/byteYuFan/NAT.git
cd NAT/server
go build -o server
修改配置文件相关信息：
Server:
Name: "Server-NAT"
ControllerAddr: "0.0.0.0:8080"
TunnelAddr: "0.0.0.0:8008"
VisitPort:
- 25565
- 57852
- 64251
- 12541
TaskQueueNum: 4
TaskQueueBuff: 32
MaxTCPConnNum: 4
MaxConnNum: 128
StartAuth: true
Database:
Username: "root"
Password: "123456"
Host: "127.0.0.1:3309"
DBName: "NAT"
// 执行命令
[root@VM-4-7-centos ~]# ./server

[ServerName] Server-NAT
[MaxServerConn] 4
[服务端开启端口] [25565 57852 64251 12541]
[服务器控制端开始监听]0.0.0.0:8080
[Start Auth Successfully!] 服务器开启认证请求
1.2. 命令行参数
命令行的优先级是最高的，您可以在命令行输入相关的配置信息
[root@VM-4-7-centos ~]# ./server --help
GO language-based Intranet penetration tool that supports multiple connections
Usage:
Server-NAT [OPTIONS] COMMAND [flags]
Flags:
-c, --controller-addr string Server controller address
-p, --expose-port ints Server exposed ports
-h, --help help for Server-NAT
-l, --log-name string The name of the log.
-x, --max-conn-num int32 Maximum connection number
-m, --max-tcp-conn-num int32 Maximum TCP connection number
-n, --name string Server name
-a, --start-auth string This is the method that whether the server start the auth. (default "true")
-b, --task-queue-buffer-size int32 Task queue buffer size
-q, --task-queue-num int32 Task queue number
-t, --tunnel-addr string Server tunnel address
如果您开启了不需要进行认证功能，那么您不需要进行配置数据库模块：
[root@VM-4-7-centos ~]# ./server --start-auth=false

客户端介绍
1. 如何使用
1.1. 基本使用
git clone https://github.com/byteYuFan/NAT.git
cd NAT/client
go build -o client
修改配置文件：
Client:
Name: "Client-NAT"
PublicServerAddr: "公网服务器域名"
TunnelServerAddr: "公网服务器隧道端口"
ControllerAddr: "公网服务器控制端口"
LocalServerAddr: "本地服务端口"
Auth:
Username: "用户名"
Password: "密码"
$ ./client.exe

[PublicAddress]
[TunnelAddress] :8008
[LocalAddress] 127.0.0.1:8080
[Conn Successfully] :8080
[ClientInfoUID] 1
[VisitAddress] :25565
[receive KeepLive package] ping
1.2. 命令行参数
$ ./client.exe --help
If the intranet is written in the go language, you need to start the intranet client before you can connect
Usage:
Client [OPTIONS] COMMAND [flags]
Flags:
-c, --controller-addr string The address of the controller channel used to send controller messages to the client
-h, --help help for Client
-l, --local-server-addr string The address of the local web server program
-n, --name string Client name
-P, --password string the password for auth the server.
-s, --public-server-addr string The address of the public server used for accessing the inner web server
-t, --tunnel-server-addr string The address of the tunnel server used to connect the local and public networks
-u, --username string the name for auth the server.
案例测试
1. 基本web接口代理
内网客户端代码:
[Client Running Successfully!]
[PublicAddress] pogf.com.cn
[TunnelAddress] pogf.com.cn:8008
[LocalAddress] 127.0.0.1:8080
[Conn Successfully]pogf.com.cn:8080
[ClientInfoUID] 1
[VisitAddress] pogf.com.cn:25565
package main
import (
"github.com/gin-gonic/gin"
"log"
)
func main() {
// 创建一个Gin的默认引擎
r := gin.Default()
// 定义一个路由处理函数
r.GET("/", func(c *gin.Context) {
c.JSON(200, gin.H{
"message": "Hello, World!",
})
})
// 启动Web服务，监听在8080端口
err := r.Run(":8080")
if err != nil {
log.Fatal("启动Web服务失败: ", err)
}
}
D:\goworkplace\src>curl pogf.com.cn:25565
{"message":"Hello, World!"}
