通过数据库之后，便于做长久分析，以及美化的输出（html,xml,excel)，做事之前就要有一个长远的可扩展
性，要么不做，要做就要能给以后扩展或是增加什么功能都提供方便，呵呵。
perl的懒惰精神就在于此。
PS:这 ...

我已经说得很清楚了perl已经把底层的东西都封装的很抽像了跟本就谈不上有什么技巧
只是为了格式化一下以方便写网络程序时查看数据包能好看一点
所以贴上来给需要的人用的,没有你想的那样秀自己水平什么的
还有我水平是很一般但我还在学习中如果像您那么牛的话,我会想着去设计一下比perl很强悍语言^_^
让外国佬也来学习我创造东西(当然这只是假想实现还是比较难的不过你嘛应该是小意思吧)

helbreathszw

如果你仔细去对比，差距还不小的， use Net:: PcapUtils;

在perl journal 2005 march那一刊上就有介绍如何这个模块的使用
Perl的强大就在于cpan,楼主你写的那个perl脚本用到了吗，还是你根本就没好好使用过cpan?
至于你说的研究语言，我因为使用Emacs，所以也在用lisp这个语言。
楼主有兴趣的话，不妨试试Emacs,写写lisp玩玩！
自己弄个语言研究，有时间吧，读完perl journal就差不多消耗了俺不少周末时间了。

很遗憾我从不用emacs只感觉vim更合自己习惯
我说已经得很明白刚这下几个模块不久写的,只觉得根c的libpcap函数库差不多少像这些东西linux基本上是用AF_PACKET和SOCK_RAW实现的而且libpcap库linux下的大部份原码我都看过所以写起来很简单
而且我不是神,什么东西一到手就玩得很精！
如果有机会的话我会把我用c写的网络库给转成perl模块自己用自己的就行了如果好用的话我会再发上来^_^

很遗憾你不用Emacs,这不能怪你，中国现状就是如此，挑最速成的学。
像lisp这种语言，恐怕国内学的人连学perl的百分之一都不到。hoho

以阁下如此浮躁的态度，我担保你的 emacs 也好不到那儿去。
至少有很多我用 vim 能够轻易完成的动作你肯定不会用 emacs 办得到。

哦，这个总不能给你比下去了
哈哈！
