Implement TCP/IP programming under DOS real model (lower)
Http://blog.csdn.net/dos5gw/archive/2010/03/29/5429582.aspx
There may be very few people using DOS, and fewer people are working on DOS.
There are many reasons.
But in terms of industrial control, there are still a lot of
packets through a system vulnerability to enable the target host to achieve the denial of service. Hackers find vulnerabilities, plant zombie programs, make machines Zombie, and attack traffic and normal access traffic are not easy to distinguish. The Udpflood is an increasingly rampant, traffic-type Dos attack, and the principle is simple. A common scenario is to use a large number of UDP packets to impact a DNS server or RADIUS authentication s
Netsh–c Interface ip set address " Local Connection "140.130.0.1 255.255.255.0: modify on Interface "Local Area Connection" IP for 140.130.0.1 , MASK for 255.255.255.0

netsh interface ip dump >c:\pc1.txt
The command is to display the IP configuration of the interface of course "local connection" and save it in the Pc1.txt text file
I'll check the C:\pc1.txt file.
Displays the IP configuration of the current "Local Area Connection" interface, and we use the command Ipconfig/all to see if the current interface configuration is
.(A) The system kernel layer to intercept the external false ARP packets, protect the system from ARP spoofing, ARP attacks, keep the network unblocked and communication security;(B) intercepting the native external ARP attack packets at the system kernel level, in order to reduce the inconvenience caused to the users after the malicious program is infected;2. Intercept IP conflicts. The IP conflict packet

Implement TCP/IP programming under DOS real model (I)
In short, I was very busy recently. I thought it was really time-consuming to make a summary of the system. I wrote half of the previous article. I wanted to simply write the process from environment setup to coding, but let's take a closer look at the previous article, which involves a lot of nonsense and has no direct cuttin

In fact, if the server's TCP/IP stack is not strong enough, the end result is often a stack overflow crash--even if the server-side system is strong enough, the server side will be too busy processing the attacker's spoofed TCP connection request to ign
