Kali Common configuration after installation

Objective

It is possible to learn with the default Kali Linux settings, but we usually need to modify some of the basic settings of the system to maximize the functionality of the Kali platform.

Basic knowledge of the network

1. Private IP Address

The Router's intranet interface (or network card) has an IP address of 192.168.1.1, which becomes a private address. because it is not available on the Internet.

IP address range can IP number

10.0.0.0 to 10.255.255.255 16 777 216

172.16.0.0 to 172.31.255.255 1 048 576

192.168.0.0 to 192.168.255.255 65 536

　　　　private address, to connect to the Internet and to surf the Internet, routers use a technology called NAT (Network address translation) . It translates the private address into an address that can be used on the internet, which is usually provided by the ISP and assigned to the router's extranet interface (another network card for the router). If the user view uses a private address directly on the Internet and does not pass through a router with NAT technology, its communication will fail. Because routers and devices on the Internet will deny access to private addresses.

　　What is the use of private IP addresses?

In an internal or private network, but not on the Internet. is assigned by DHCP.

2. Default gateway

The router divides two networks, intranet and extranet. and provides some basic security features, such as a basic firewall. In addition, routers provide a way to access the extranet from the intranet. Therefore, the router's intranet address is a two-client access to the external network. This address is called the default gateway.

　　Gateway, which is to regard it as the only exit from the town.

The computer also needs to know the exit from the intranet, which is the default gateway .

　　3. Domain Name server

Here, very simple, not much to repeat.

　　4. DHCP Service

In the network domain, nothing is more magical than DHCP, if the computer has been configured for automatic DHCP configuration, then the user only need to plug in the network cable to be able to surf the Internet. When the computer initiates network traffic to find a DHCP server, a broadcast request is sent to look for the DHCP server. The server responds to the client and specifies the configuration required to request the computer, including the IP address, default gateway, domain name server, and subnet mask. In most cases, this is a good way to configure the NIC. But if you are conducting penetration testing, using DHCP to configure your network will tell the entire network that you are already logged into the network. This is usually not a good thing.
