packet tracer 标注的字体大小
学习CCNA课程大家做实验最常用的模拟器就数packet tracer了。 下面是用packettracer平台做的实验，都是独家的，网上几乎找不到，这些包含了CCNA涉及的所有实验，是每个学习CCNA人求之不得的“攻略”！ packettracer到Cisco官网就可以下载得到，就不上传了~呵呵。 文件: E2-PT实验.part1.rar 大小: 2929KB 下载: 下载 文件: E2-PT实验.part2.rar 大小: 2824KB 下载: 下载 本文来自ChinaUnix博客，如果查看原文请点：http://blog...

一个简单的 stack trace 例程，C/C++ 两套接口
debug.h，前半是 C 接口，后半是 C++ 接口
[code]#ifndef DEBUG_H
#define DEBUG_H

The sender first enters a CSMA delay period, listening for an idle channel. The sender then transmits a packet start symbol at 10Kbps, which a receiver samples for at 20Kbps. As the following data is transmitted at 40Kbps, after the start symbol the receiver must synchronize to the sender at a finer granularity. The sender pauses for a few bit times after the start symb...

packet Analysis Aha, finally it is time to start using our newly obtained Jedi skills! (wheee!!) This section will focus on peaking into the packets to extract the information (which is what we wanted to begin with). First off we must arm ourselves! Go ahead and get all the relevent RFC's. Lets start off with RFC 791 (IP) RFC 768 (UDP) RFC 826 (ARP) RFC 792 (ICMPv4) and of course RFC 7...
Writing a Basic packet Capture Engine Hi :-), this section consists of a discussion on how to write a simple packet capture engine. The goal is to demonstrate methods of capturing and filtering multiple packets to aid in packet analysis. All the juicy info on disecting IP packets and forging new ones are reserved for later sections.. Yes I can see your dissapointment, but you must admit that a ...
