method needs to write the driver at the core layer of the system, which requires the writer to be familiar with the working mechanism of the core layer of Windows operation, and the driver is very high in code quality, which can cause the system to crash with a slight carelessness, b) win2kfilter-hookdriver. This is a driver from the Windows2000 system, which is
Han o Sinox not only executes Windows applications through wine. Windows drivers can also be executed through NDISHan o sinox using the Windows NDIS driverThe detailed implementation method is to convert the Windows driver sys driver into a kernel module KO file with Ndisgen. Then let the system load the KO module to be able to use. The
Question:[Original] differences between NDIS intermediate layer driver development in win7 and Windows XPAuthor:TianhzTime:2011-07-21,14: 58: 04Link:Http://bbs.pediy.com/showthread.php? T = 137545 Network Data is composed of packets sent and received over the network. NDIS provides data structures to describe them. NDIS6.0 provides the following data structu
This problem is a classic problem for most people who learn the intermediate NDIS layer. When asked on the Forum, others will only tell you the approximate method and steps. Here we post the specific code, hoping to help the buddies who study the NDIS middle layer: Ndis_statusMysendpacket (Ndis_handle ndisbindinghandle,Ndis_handle ndissendpacketpool,Pvoid pbuffer,Ulong dwbufferlength){Ndis_status status;Pnd

NDIS is short for Network Driver Interface Specification. The main purpose of NDIS is Is to develop a standard API for NIC (network interface card, Netwok interface cards. Mac (Media Access Controller) the device driver encapsulates all Nic hardware. In this way, all NICs using the same media can be accessed through
Email: flashsky@xfocus.org Site: http://www.xfocus.net www.shopsky.com/ In normal Windows 2000, the main method to implement package filtering is to write the NDIS filter driver, which requires a high skill and requires a lot of details. However, for many applications, you only need to be able to more easily filter IP packets. In fact, NDIS provides a write filt
Due to communication problems in the project, prepare a tool that can simulate packet loss for troubleshooting and make up for the network knowledge. At the beginning, I thought that the SPI technology could be used to solve the problem. Later I realized that packet loss and so on must be completed under the protocol layer. For the protocol layer, I wanted to publish a complete article after it was done.ArticleThe result shows that the difficulty is a little higher than expected. There is no way

--- Inline hook implements NDIS HookThe previous section describes how to implement the NDIS Hook by obtaining ndis_protocol_block. The second method is the inline Hook method. Inline hook is nothing new. It is nothing more than embedding a JMP machine command in the first part of a function. Before the function executes valid code, it jumps to our proxy function, after necessary processing is done in our p
Key Technologies for implementing NDIS Hook Firewall Firewall cannot be mentioned when talking about network security. At present, most firewalls in China adopt the TDI technology, and NDIS can be regarded as a relatively advanced technology (if you don't think so, it can only mean that I am outdated, haha) technical details about implementing the NDIS firewall a
