ecserver.pl 源代码

作者：黑客防线网安网站维护基地来源：黑客防线网安网站维护基地浏览次数：0

下面的代码有用到unix/linux的系统功能所以不能在NT上使用。
运行这个代码，你需要在相同目录下面放一个文本文件chat.log
聊天内容将保存在这个文件内。代码调用unix/linux处理log的function
写入/读取聊天内容。
至于多进程，好像socket自己就可以处理。。。那个listen()你自己看一下。
Perl我是几乎什么都不懂的。所以只好您老人家自己研究了。：）
搞明白了别忘了教小弟几招。
另外，nt平台上可以用vc写chatserver嘛。(这个我更不懂了)
