内网穿透工具


natcross是做什么的?

  • 需要自己提供硬件支持、部署的内网穿透工具
  • 提供TCP协议类型的内网穿透服务,包括但不限于http(s)、数据库连接、ssh等协议
  • 支持https协议转http协议与应用交互方式
  • 支持无加密、控制端口加密交互、数据加密交互方式
  • 主要服务场景,需要将内网的应用开放到公网,如微信小程序开发调试、支付回调等

打包使用

服务端-ServerApp打包:

修改ServerApp.java中serviceIp为公网服务器的IP

mvn clean compile package -PserverApp

客户端-ClientApp打包:

mvn clean compile package -PclientApp

安装

  1. 需要一台可在公网访问的机器,并将控制端口(默认 servicePort 10010)、数据端口(如tomcat,开放公网 listenPort 8081端口,外网连接时要对应数据端口8081)开放出来
  2. 将ServerApp.jar包放在公网可访问的机器并运行,打包前需要修改serviceIp为公网服务器的IP
  3. 将clientApp为入口进行运行,destIp:destPort为要开放的内网应用,如本地的tomcat(127.0.0.1:8080)
  4. 用浏览器访问serviceIp:listenPort便可以访问到内网的tomcat

参数解释

ServerApp:

字段 解释
serviceIp 公网服务器的IP
servicePort 服务端的控制端口,主要用来与客户端进行指令交互
listenPort 服务端的监听端口,也就是部署完成后,在外网访问 serviceIp:listenPort 的方式对内网应用进行访问
aesKey 交互密钥key,保证数据的秘密性,可以查看 SecretInteractiveModel.java 中的fullMessage和checkAutograph中确认密钥的使用方式。
如果你使用了secretAll方式进行部署,这个key还是数据加密的key,可以在 SecretPassway.java 中确认密钥的使用方式
tokenKey 交互签名key,签名同aesKey
sslKeyStorePath ssl证书的路径,默认方法只支持pkcs12的证书格式,使用这个证书可以做到https协议转http协议
sslKeyStorePassword 证书密码
createServerSocket 创建socket的方式,主要针对普通socket和sslSocket的方式进行封装,结合ssl证书使用

ClientApp:

字段 解释
destIp 要开放到公网的内网应用所在机器的IP
destPort 要开放到公网的内网应用的端口
serviceIp 复用ServerApp的字段,所以要保证部署包和内网包的参数一致
servicePort 复用ServerApp的字段,所以要保证部署包和内网包的参数一致
listenPort 复用ServerApp的字段,所以要保证部署包和内网包的参数一致
aesKey 复用ServerApp的字段,所以要保证部署包和内网包的参数一致
tokenKey 复用ServerApp的字段,所以要保证部署包和内网包的参数一致

内网穿透思路

因NAT网内CLIENT可以正常连接到SERVER端,并且能够保持一段时间的长连接,则由CLIENT发起连接,建立SOCKET对,在SERVER收到外部请求时,可以通过已经建立好的SOCKET将数据传输给CLIENT,CLIENT使用相同的方式将数据发送给指定的网络程序,网络程序回发数据后则按原路返回给请求方。 时序图
