Before launching various "hacker behaviors", hackers will take various measures to detect (or "detect") The host information of the other party, in order to determine the most effective method to achieve your goal. Let's see how hackers know the most basic network information-the IP address of the other party, and how users can prevent their own IP

Running an operating system under a virtual machine, especially a Linux system, is already a very common practice. Sometimes you want to build a (simulated) server under a virtual machine for host access, such as setting up a telnet/ssh server. At this point, you will find that every time you start a virtual machine, VMWare assigns a dynamic IP address to the vir
Determine whether the IP source is China Telecom or China Netcom, which is often used in the background program of the site. the typical practice is to query the database. The database stores the IP address range of China Netcom (or China Telecom), and then determines whether the IP
MAC address of the VM Nic for the VMnet2 Internet Nic is: 00: 0C: 29: 3C: 78: 4B.
After the above configuration, we start to configure the eth0 and eth1 NICs of the VM, as shown below:
In this VM, The eth0 Nic is configured as an Internet IP address, corresponding to the VMnet0 Nic of VMWare, And the gateway is 192.168.3.1.
