Whether the same network segment can do the same IP and MAC address,In fact, you can completely change the IP of the two computers to the same as the Mac, not only the internet but also no IP conflict. This method can not only break through the routing blockade used in the ADSL shared Internet, but also can be used in
proxy server software that comes with Windows systems, such as Sygate and early proxy server software such as WinProxy and Wingate, the most widely used is shared by ICS or Sygate.
Gateway-based sharing has the following features:
(1) A high-configuration computer is required to serve as a shared gateway server for a long time, and the corresponding software
In many applications, you may need to record the real IP address of the user. In this case, you need to obtain the real IP address of the user. In JSP, you can obtain the IP address of the client by: request. getRemoteAddr (), whi
In JSP, the method for obtaining client IP is: request.getremoteaddr (). This method is effective in most cases, but can not obtain the real IP address of the client when the reverse proxy software such as Apache,squid is passed.

However, the real IP address of the client cannot be obtained through reverse proxy software such as Apache and squid. If the reverse proxy software is used, the IP address obtained using the request. getremoteaddr () method is 12
Use the Linux system IP address to disguise the hacker-Linux Enterprise Application-Linux server application information. The following is a detailed description. Firewalls can be divided into several different security levels. In Linux, because there are many different firewall software options, the security can be low and high, and the most complex

Firewalls can be divided into several different security levels. In Linux, because there are many different firewall software options, the security can be low and high, and the most complex software can provide almost no penetration protection capabilities. However, the Linux core itself has a simple mechanism called "Disguise". Apart from the most specialized hacker attacks, it can withstand the vast major

In the formal conduct of various "hacker behavior", the hacker will take various means to detect (also can say "reconnaissance") the other party's host information, in order to determine the most effective way to achieve their goals. Take a look at how hackers learn the most basic network information-the IP address of each other, and how users can protect themselves from
