怎样使用花生壳域名解析出IP?----即通常所说的"上线"

2010年10月05日 星期二 下午 01:09

本例仅为学习.一个写远控的,连上线都不会.一问三不知,还能算是个网络编程

的程序员?上线:就是敲门,1台电脑给另外一台电脑敲门,有人在就进去,没人在

就回去.这是最基本的常识.

方法:用的是原始套接字icmp获取的,其实就是一个ping程序(包括IP与网站名

的那种ping,仅IP的不可以)

主程序:ping.h与封装好的.直接在你的程序中调用.其实算

不上什么本事,都是抄来的.因为不是搞专业的远控,仅是学习,所以我也没花时

间仔细去学这.cpp

顺便介绍下花生壳:从/下载花生壳软件,登录后

116.209.15.221就是本机现在的外网就是你账号对应

的网站,无论你用的是哪一台机器.(那么端口呢?端口指定的一样的).花生壳其

它的就不用管了.你只要做一步即可:打开花生壳软件,登录你的账号即可.难吗?

不难,很简单的1步
