First, the purpose and requirements of the experiment1, understand the scanning technology working principle;2, deepen the understanding of the bottom of the network;3, master the basic usage of common scanning tools;4, the basic method of learning Scanner program design.

for client access is named "Public Address ", the network connection used for communication between nodes is named "private address ". · Enter the command "ipconfig/all" on the computer server to view the computer's IP address. 6 shows that the "Public Address" IP address is 192.168.0.2 and the "private address" IP address is 192.168.1.2. run the "ipconfig/all" command on the client to view the IP address

I. Differences between the three types of networks 1. vmnet0 Vmnet0 is actually a virtual bridge. This bridge has several ports, one for connecting your host, and the other for connecting your virtual machine. Their locations are equal, no one is the gateway. So in bridged mode, you can make the virtual machine the same as your host. 2. vmnet1 Vmnet1 is a host-only network mode, which is used to establish an isolated network environment. vmnet1 is also a virtual switch, and a port of the

timeout was 2 seconds. This shows that our computer does have a DNS resolution fault. TIPS: If the DNS resolution is normal, the correct IP address will be returned. For example, if I use the address www.jb51.net for query resolution, the name: jb51.net, addresses: 61.129.70.67, 61.135.133.104 information will be obtained. (2) check whether the DNS server works properly: In this case, we need to check the DNS address used by our computer and its running status. Step 1: confirm that your

; Enter cmd to enter the command line mode. Step 2: Enter the NSLookup command and press enter to go To the DNS resolution query page. Step 3: the command line window displays the DNS server address used by the current system. For example, the IP address of the author's DNS server is 202.106.0.20. Step 4: Enter the domain name of the site you cannot access. If it cannot be accessed, DNS resolution may fail. We will receive a prompt message for DNS request timed out and timeout was 2 seconds.
