| 详谈调用winpcap驱动写arp多功能工具 一 winpcap驱动简介  winpcap(windows packet capture)是windows平台下一个免费，公共的网络访问系统。 (编者注：WinpCap开发包可以到以下两个网址下载: (1)http://winpcap.polito.it/ , (2)VC知识库工具栏目 ) 开发winpcap这个项目的目的在于为win32应用程序提供访问网络底层的能力。它提供了以下的各项功能： 1> 捕获原始数据报，包括在共享网络上各主机发送/接收的以及相互之间交换的数据报； 2> 在数据报发往应用程序之前，按照自定义的规则将某些特殊的数据报过滤掉； 3> 在网络上发送原始的数据报； 4> 收集网络通信过程中的统计信息。 winpcap的主要功能在于独立于主机协议（如TCP-IP)而发送和接收原始数据报。也就是说，winpcap不能阻塞，过滤或控制其他应用程序数据报的发收，它仅仅只是监听共享网络上传送的数据报。因此，它不能用于QoS调度程序或个人防火墙。 目前，winpcap开发的主要对象是windows NT/2000/XP，这主要是因为在使用winpcap的用户中只有一小部分是仅使用windows 95/98/Me，并且M$也已经放弃了对win9x的开发。因此本文相关的程序T-ARP也是面向NT/2000/XP用户的。其实winpcap中的面向9x系统的概念和NT系统的非常相似，只是在某些实现上有点差异，比如说9x只支持ANSI编码，而NT系统则提倡使用Unicode编码。 本文讨论的是packet.dll所提供的各种函数，因为它们完全可以实现本文所希望的各项要求。但是如果你有其他特别的或更高级的要求，winpcap也提供了另一个动态连接库wpcap.dll。虽然wpcap.dll依靠于packet.dll,但是它却提供了一种更简单，直接，有力的方法来更好的利用编程环境。比如捕获一个数据报，创建一个数据报过滤装置或将监听到的数据报转存到某个文件等，wpcap.dll都会为你提供更加安全的实现方法。
首先介绍一些相关的数据结构： 下面，将介绍T-ARP用到的各个函数，他们都是在packet.dll中定义的： 2> VOID PacketCloseAdapter(LPADAPTER lpAdapter) 3> VOID PacketFreePacket(LPPACKET lpPacket) 4> BOOLEAN PacketGetAdapterNames(LPSTR pStr,PULONG BufferSize) 5> BOOLEAN PacketGetNetInfoEx(LPTSTR AdapterNames,npf_ip_addr *buff, PLONG NEntries) 6> BOOLEAN PacketGetNetType(LPADAPTER AdapterObject, NetType *type) 7> BOOLEAN PacketGetStats(LPADAPTER AdapterObject,struct bpf_stat *s) 8> PCHAR PacketGetVersion() 9> VOID PacketInitPacket(LPPACKET lpPacket, PVOID Buffer, UINT Length) 10> LPADAPTER PacketOpetAdapter(LPTSTR AdapterName) 11> BOOLEAN PacketReceivePacket(LPADAPTER AdapterObject,LPPACKET lpPacket,BOOLEAN Sync) 12> BOOLEAN PacketSendPacket(LPADAPTER AdapterObject,LPPACKET lpPacket, BOOLEAN Sync) 13> BOOLEAN PacketSetBuff(LPADAPTER AdapterObject,int dim) 14> BOOLEAN PacketSetHwFilter(LPADAPTER AdapterObject,ULONG Filter) 15> BOOLEAN PacketSetNumWrites(LPADAPTER AdapterObject,int nwrites) 16> BOOLEAN PacketSetReadTimeout(LPADAPTER AdapterObject,int timeout)
选项: 原理及实现过程： -m 以本地主机的名义(本地主机的ip和mac)向指定ip网段内的所有主机发送广播(ff:ff:ff:ff:ff:ff)ARP Request数据报，存活的主机就会发送ARP Reply数据报，这样就可以获得当前存活主机的列表。因为在很多网关上都对ARP Request做了限制--非内网ip发送的ARP Request数据报不会得到网关的回应，如果你用内网的其他某台主机的ip来发送ARP Request数据报，如果填写的mac地址和相应的ip不合，就会出现ip冲突。所以最好还是用自己的ip和mac地址来发送请求。 -a 以本地主机的名义(本地主机的ip和mac)向指定ip网段内的所有主机发送31位伪广播地址(ff:ff:ff:ff:ff:fe)的ARP Request数据报，只有正在嗅探的主机才会发送ARP Reply数据报，这样就可以获得当前存活主机的列表。嗅探中的win2000系统还会对16位伪广播地址(ff:ff:00:00:00:00)做出回应；而嗅探中的win95/98/me不仅会回应16位伪广播地址，而且也会回应8位伪广播地址(ff:00:00:00:00:00)，而*NIX系统对各种广播地址所做出的反应却有些不同。在此我们选择31位伪广播地址，是因为绝大多数的系统在嗅探时都会对它做出回应。而正常状况下的各种系统，都不会对31位伪广播地址做出回应。 -s (ARP欺骗spoof) 需要强调的是在某些局域网(如以太网)内，数据报的发送与接收是基于硬件地址的，这是我们实现欺骗的基础。首先获得指定的两台主机(假设为 A 和 B)的mac地址，然后向A发送ARP Reply数据报，其中的源ip地址为B的ip地址，但是源mac地址却是本地主机的mac地址，这样主机A就会认为主机B的mac地址是本地主机的mac地址，所以主机A发送到主机B的数据报都发送到本地主机了。同理向主机B发送ARP Reply数据报，通知它主机A的mac地址为本地主机的mac地址。这样主机A和主机B就会把目的主机的mac地址理解为本地主机的mac地址，于是他们之间相互发送的数据报都首先到达了本地主机，而先前我们已经将本地主机设置了ip路由功能，系统会自动将数据报转发到真正的目的主机。其间，你就可以监听它们通信的各种数据报了。 -s (网络嗅探sniff) 如果指定的两个目的主机均为本地主机，那么就只是将网络适配器设置为混杂模式，这样就可以监听到流过本地主机网络适配器的各种数据。 -s (ip冲突shock） 如果你选择欺骗的两台主机是同一台非本地主机(假如是主机C)，那么就会不断地向主机C发送ARP Reply数据报，报文中的源ip地址就是主机C的ip地址，但是源mac地址却是本地主机的mac地址，因此主机C就会发现有另一台主机同时拥有和自己相同的ip，这就是ip冲突攻击。如果是非xp系统,都会跳出一个ip冲突的提示窗口，而xp系统也会有类似的警告。但是请注意，在主机C的系统事件查看器中，会留下本地主机的mac地址与之冲突的恶心记录，所以你最好不要滥用这个功能。 -r 在实现了ARP欺骗的情况下，向主机A和B发送ARP Reply数据报，通知主机A(B)注意主机B(A)的mac地址为主机B(A)自己的mac地址，这样主机A和B就会更新他们的ARP缓存，实现正常的数据通信。 2> 主要代码分析 PacketGetAdapterNames((char *)adaptername,&adapterlength) //获得本地主机的网络适配器列表和描述； lpadapter=PacketOpenAdapter(adapterlist[open-1]);
