飘零的代码 piao2010 ’s blog

此文是我的计算机网络课作业，拿出来凑凑数。

第一次接触“抓包”这个词应该是在高一的时候，当时刚刚迷上网络安全，经常从《黑客X档案》中看见一些利用抓包技术入侵的文章，最常用的工具就是WsockExpert， read more »

官方的文件通俗易懂，相信有需要的朋友们一看就能明白。

0. Introduction, and some stuff you should know.
————————————————

0.3.7 (Beta). It has been a while I know. But this year has been a hell, last
year of uni, projects, thesis, …. it didn’t stop. Well that is behind us
now, the most important thing, is that I’m back working on the program again,
and intend to keep on doing it.

I hope you enjoy this beta version. Like always, I removed some bugs. There
is a new ‘logging’ feature. It is now possible to record traffic with
Sniffit and process it later! (it is completely different from the logging
done in the 0.3.6 version, that is known to some hardcore Sniffit users)
Please take a minute to skim through the text and read the passages marked
with a ‘*’, these are the new features.
(Please read BETA-TESTING)

I use the libpcap library developed at Berkeley Laboratory, for easy
porting (Read the licence).
