You can use Ifconfig command followed by up option and interface name to start the network interface and for stopping it use the down option. You have more than 1 interface, and you want to use only 1 adapter, then disable other adapters. Sometimes you find that network interface is not responding properly, you will have to enable and disable. If you didn’t create a normal user in Kali Linux then you are using the system by the root user. You can run this command as a normal user, sudo user, or root user. You have seen the result of ifconfig command, You can see assigned IP address, MAC address, Netmask, for IPv4, etc. TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 :~ $ ~$ sudo ifconfig -a TX errors 0 dropped 0 overruns 0 carrier 0 collisions 0 If you are checking only network configuration then you don’t have a need to be root. I mean “You must be root to make changes in network configuration. Here we are discussing Kali Linux, I will explain tasks used in Linux. Following command is used to check the status of the networking cards in Kali Linux:īefore run command makes sure, you are working as root. There are different methods for windows and Linux operating systems. but the most important question: How do you check the Kali Linux network configuration? So configure the network and get into the network. The network should have proper IP Address, subnet mask, Default gateway, domain name server, etc. Intentionally vulnerable VMs will generally have more open ports than your own attack or desktop machines.If the network card is not configured properly, then you are out of network and configuration is important for network security. This is the easiest but slowest method since you’re scanning every open port on your network. To find active hosts within a network, type the following command in your terminal: We’re going to focus on using nmap to find and list all hosts on a network, and we’re assuming you already have nmap on your Kali Linux machine. Nmap is compatible with every major operating system including Mac OS, Windows, and Linux. Hence nmap assumes that the host is not up. The hosts you have on the network are blocking ping and the port 80 is not accepting connections. This is not 100% reliable because modern host based firewalls block ping and port 80. If ping fails it tries to send syn packets to port 80 (SYN scan). When you run the below command, nmap tries to ping the given IP address range (192.168.73.1 to 192.168.73.254) to check if the hosts are alive. or you can use any number of toolkit distributions for the tool. We do this by typing Ĭommand: netdiscover -P -i eth0 -r 192.168.73.0/24Īnother popular tool which is nmap can also be used to find out the live hosts within a network. In the command below, we are asking netdiscover to find all the live hosts with IP addresses between 192.168.73.1 to 192.168.73.255. In netdiscover, we can use the -r switch (for range) and then in CIDR notation provide it the network range we want it to scan. To discover the IP’s on an internal network, we will usually want to scan a range of IP addresses. Netdiscover is a relatively simple tool, so there are not a lot of options. When you click on netdiscover, it opens a screen which displays some basic help. You can find netdiscover by going to Kali Linux machine, then Information Gathering, then Route Analysis, about midway down the long list of discovery tools. One of the most popular tool to do this is the excellent open source tool netdiscover. This is accomplished by probing the network and looking for a response. No matter how good our skills are, we need to find systems that we can attack. While solving CTF or bug bounty challenges, sometimes you need to find out the IP address of the machine because that machine is not logged in at that time. We realize that some people who like to break stuff haven’t had experience in building stuff.
