Kali Linux configure network manually a Complete Guide for beginners

Hello and welcome on my blog, there Vijay Kumar,

This article about the ” Kali Linux configure network manually ” In this topic, I will cover all about the Kali Linux network configuration of LAN (Ethernet) and Wireless LAN adapter as well. After reading this article you will able to assign IP manually and by DHCP server as well.

Kali Linux Network Configuration for Ethernet Connection

Network interfaces (LAN adapter, wireless adapter, usb adapter, fast Ethernet) are responsible to connect and make communication between two or more computers in a network.

If the network card is not configured properly, then you are out of network and configuration is important for network security. The network should have proper IP Address, subnet mask, Default gateway, domain name server, etc.

So configure the network and get into the network. but the most important question:

How do you check the Kali Linux network configuration?

There are different methods for windows and Linux operating systems. 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:

Before run command makes sure, you are working as root. I mean “You must be root to make changes in network configuration.

If you are checking only network configuration then you don’t have a need to be root.

You have seen the result of ifconfig command, You can see assigned IP address, MAC address, Netmask, for IPv4, etc.

You can run this command as a normal user, sudo user, or root user. If you didn’t create a normal user in Kali Linux then you are using the system by the root user.

Enable/Disable network interface cards

Sometimes you find that network interface is not responding properly, you will have to enable and disable.

You have more than 1 interface, and you want to use only 1 adapter, then disable other adapters.

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 can use the following syntax to enable and disable network interface cards.

#ifconfig eth0 down

#ifconfig eth0 up

Assign IP Address for the network (eth0 or wlan0)

Eth0 is the number of a wired network interface card. if you want to assign IP address for wireless adapter replace eth0 by wlan0. The current configuration of this adapter can be changed by using the following command and this command will assign new IP address for your computer interface

$sudo ifconfig eth0 192.168.1.10

Kali Linux network configuration with IP address and Netmask

Netmask is used to indentify the network address. It can be configured by using given command. This will set the ip address 192.168.1.10 and set the subnet mask 255.255.255.0

$sudo ifconfig eth0 192.168.1.10 netmask 255.255.255.0

Add default gateway

Default gateway is added or changed, by using following command. It will set the default gateway 192.168.1.1

#route add default gw 192.168.1.1
OR
$sudo route add default gw 192.168.1.1

Add dns-namesevers

In Linux Domain Name Server or DNS can be set or modifying the resolv.conf in the /etc directory. It can be changed by editing this file. add the following sytex in terminal

#echo nameserver 8.8.8.8 > /etc/resolv.conf

This command will remove the current nameserver and set 8.8.8.8. It can be added alternate nameserver by using following syntax

#echo nameserver 4.4.4.4 >> /etc/resolv.conf

Kali Linux network configuration from DHCP

DHCP services are one of the easiest ways to configure an Ethernet. A free DHCP server provides all required configuration settings for the network cards. Use the following method:

make these entries

iface eth0 inet static

Save the file and exit to complete the modification. It is required to take down the network and again bring up Ethernet interfaces to applying this configuration.

Use the following command to configure the network adapter
#dhclient eth0

This will configure the network adapter using the settings provided by the DHCP Server.

какую ошибку пишет?

у меня после режима монитора вручную надо было всегда поднимать

в том то и дело, что я не запускал режим монитора. Ошибку не скажу точно, смысл в том что писало мол устройство не найдено, попробую переустановить.

переустановил, те же грабли. при вводе ip link set wlan0 up, отвечает RTNETLINK answers: Operation not permitted

Да я устанавливаю с воткнутым кабелем. То что проблема с дровами скорее всего, тоже догадываюсь. Но как их переустановить немного не понимаю. Исключил и рабочее окружение, та же проблема на кедах и гноме. На арче норм заводится адаптер.

Помнится раньше, во времена кали 18 го года, что бы видел некоторые адаптеры, надо было закинуть дополнительно файлы firmware на флешку с записанной кали кажется. Но уже не помню где их качать(

Если не помогает попробуй:

sudo service network-manager restart

Failed to restart network-manager.service: Unit network-manager.service not found

А что касается подмены дров от 8821, то ошибку выдает и не ставится.

sudo service network-manager restart

Failed to restart network-manager.service: Unit network-manager.service not found

А что касается подмены дров от 8821, то ошибку выдает и не ставится.

О_о
покажи последовательный вывод следующего:

после установки
lshw
и выполнение команды
lshw -C network
вот что показало

на 99% уверен, что проблема в дровах. На Арче все работало, в форточках тоже. Подключил внешний адаптер AR9271 и он работает как надо. Но не встройка.

Вот если бы можно было нормально поставить нужные инструменты, и запуск их с ярлыков как у кали, в гробу бы я видел эту ос. Остался бы на арче. Но на арче lazy script не ставится и не понимаю как поставить вот так с ярлыков и с иконками что бы в гноме, как в кали, нужные инструменты.

На форумах нашел вроде бы решение, но что то не пойму как ставить этот драйвер.

Configuring the Network

September 30, 2017 by digip Comments are off

5.1. Configuring the Network

5.1.1. On the Desktop with NetworkManager

In a typical desktop installation, you’ll have NetworkManager already installed and it can be controlled and configured through GNOME’s control center and through the top-right menu as shown in Figure 5.1, «Network Configuration Screen».

Figure 5.1. Network Configuration Screen

The default network configuration relies on DHCP to obtain an IP address, DNS server, and gateway, but you can use the gear icon in the lower-left corner to alter the configuration in many ways (for example: set the MAC address, switch to a static setup, enable or disable IPv6, and add additional routes). You can create profiles to save multiple wired network configurations and easily switch between them. For wireless networks, their settings are automatically tied to their public identifier (SSID).

NetworkManager also handles connections by mobile broadband (Wireless Wide Area Network WWAN) and by modems using point-to-point protocol over ethernet (PPPoE). Last but not least, it provides integration with many types of virtual private networks (VPN) through dedicated plugins: SSH, OpenVPN, Cisco’s VPNC, PPTP, Strongswan. Check out the network-manager-* packages; most of them are not installed by default.

5.1.2. On the Command Line with Ifupdown

Alternatively, when you prefer not to use (or don’t have access to) a graphical desktop, you can configure the network with the already-installed ifupdown package, which includes the ifup and ifdown tools. These tools read definitions from the /etc/network/interfaces configuration file and are at the heart of the /etc/init.d/networking init script that configures the network at boot time.

Using sudo to access Administrative Privileges

The sudo (super user do) command allows privileged users to run commands with administrative permissions. This gives full access to items that may be restricted to only the root user, such as programs in /sbin/ or access to network options that are useful for common penetration testing tools.

The command takes one argument, being the subsequent command that will be run with administrative permissions. One useful use case when dealing with services is to elevate to the root user account. To elevate to root user, we will use the command su (substitute user) to create a shell under the root user. The substitute user command takes a user account as an argument. Additionally, the su command has a useful flag ( —login, or -l, or -) to use the substituted user’s login environment. Multiple commands in the following chapter require the use of sudo, as such we will elevate to the root user to seamlessly execute these commands.

Each network device managed by ifupdown can be deconfigured at any time with ifdown network-device. You can then modify /etc/network/interfaces and bring the network back up (with the new configuration) with ifup network-device.

Let’s take a look at what we can put in ifupdown’s configuration file. There are two main directives: auto network-device, which tells ifupdown to automatically configure the network interface once it is available, and iface network-device inet/inet6 type to configure a given interface. For example, a plain DHCP configuration looks like this:

Note that the special configuration for the loopback device should always be present in this file. For a fixed IP address configuration, you have to provide more details such as the IP address, the network, and the IP of the gateway:

For wireless interfaces, you must have the wpasupplicant package (included in Kali by default), which provides many wpa-* options that can be used in /etc/network/interfaces. Have a look at /usr/share/doc/wpasupplicant/README.Debian.gz for examples and explanations. The most common options are wpa-ssid (which defines the name of the wireless network to join) and wpa-psk (which defines the passphrase or the key protecting the network).

5.1.3. On the Command Line with systemd-networkd

While ifupdown is the historical tool used by Debian and Kali, and while it is still the default for minimal installations, there is a newer tool worth considering: systemd-networkd . Its integration with the systemd init system makes it a very attractive choice. It is not specific to Debian-based distributions (contrary to ifupdown ) and has been designed to be very small, efficient, and relatively easy to configure if you understand the syntax of systemd unit files. This is an especially attractive choice if you consider NetworkManager bloated and hard to configure.

Enable Wi-fi on Kali Linux

I just installed Kali Linux on Dell Inspiron 1545, and am unable to get wireless connection.

I attempted the following

I even tried commands I used when I installed Ubuntu on the same laptop

UPDATE

sudo apt-get install kali-linux-wireless

but I still cannot detect and connect to my home wi-fi.

Tried first solution

I tried first solution, but when I go to Administration > System, I get package manager. I searched for everything Broadcom downloaded, installed, rebooted, but still no wireless.

There has to be an easy solution .

I was getting errors with install. After I reboot, still no wireless detector.

Update

I’m trying all your suggestions . seems I will have to read the links you provided. Who knew getting wireless would be so difficult! I will extend bounty time if possible.

May be your wireless card is in turned off state, does the laptop have any dedicated physical switch or key combo(like Fn+F3 on my acer laptop) to turn on/off Wi-Fi ? most laptops also have a LED to show Wi-Fi card state.

Device firmwares are not pre installed in kali-linux(my last used version 1.0.4 can’t tell about latest versions) , so if not already installed, install them.

sudo apt-get install firmware-linux firmware-linux-free firmware-linux-nonfree

Install Broadcom wireless card firmware

sudo apt-get install firmware-brcm80211 firmware-b43-installer firmware-b43legacy-installer broadcom-sta-dkms

Then use proper kernel drivers, b43 or b43legacy, iwlwifi is Intel Wi-Fi card driver so firmware-iwlwifi is not necessary.
