需求分析 在软件开发测试过程中,我们会经常遇到需要网站部署测试.给客户演示.APP开发的调试这样的需求.通常的做法是申请一个域名和空间,将网站放到外网上给客户演示. 这种方法确实可行不过会有两点不好,第一是增加了开支,不利于调试. tunnel可以让公网访问内网部署的站点,对于软件开发测试很有帮助. 解决方案 现在国内关于tunnel的代理服务器有很多,主要如下: 1. qydev.com 2. natapp.cn 3. www.ngrok.cc 由于我使用的是qydev.com提供的方法,所以…

ssh反向通道的可用场景之一:从外网访问内网的主机.所必须的是你需要一个有ssh登录权限的公网主机. 步骤如下(将内网主机称作A,公网ssh主机地址为hostP ): 1.在内网A上执行 :localhost: [user@]hostP #需要身份验证,根据你的情况:无密码.-i 秘钥文件.输入密码 其中remoteListenIp指在hostP上监听22222端口的ip,可以省略.在没有对hostP上的GatewayPorts参数进行设置时不起作用,默认只绑定到本地回环,这可能导致只能在hos…

在笔者的系列微信开发教程中,有一个比较基础且重要的一节:微信开发的调试.在文章中我推荐了两种动态域名解析的工具用于将本地的开发环境部署成服务器,一种是花生壳,一种是ngrok,但毕竟我等屌丝用不起或者不愿意付费试用花生壳,导致花生壳经常来大姨妈(解析失败).而ngrok的服务器是国外的,而天朝的网络想必大家都懂的.那在这样的一个环境下,调试微信的时候显得特别不方便.无意中呢,看到tunnel这样一个工具,看了下官网的介绍后,觉得尝试使用下,最终让我觉得放弃使用花生壳和ngrok了.至于为何,那我…
