I have created a hotspot following a previous post . In this post I explain how I avoided the errors and succussfully created the hotspot on Kali Linux.

• If you have a fresh installation of Kali Linux, first ensure the internet connection. If you are connected to Wi-Fi and still having no internet, then use the following command.

sudo dhclient eth0 or sudo dhclient wlan0

• Next, install hostapd(hotspot server) and dnsmasq (dns dhcp server).

apt-get install hostapd dnsmasq

• Prevent the installed services starting at the start up

 sudo service hostapd stop
 sudo service dnsmasq stop
 sudo update-rc.d hostapd disable
 sudo update-rc.d dnsmasq disable

• Setup the configuration file of dnsmasq.

gedit /etc/dnsmasq.conf

# Bind to only one interface
bind-interfaces
interface=wlan0
dhcp-range=192.168.150.2,192.168.150.10

• Setup the configuration file of hostapd.

gedit /etc/hostapd.conf

interface=wlan0
driver=nl80211
ssid=myhotspot
# Set access point harware mode to 802.11n
hw_mode=g
ieee80211n=1
channel=6

• Create hotspot.sh.

#!/bin/bash
# Start
sudo ifconfig wlan0 192.168.150.1
sudo service dnsmasq restart
sudo sysctl net.ipv4.ip_forward=1
sudo iptables -t nat -A POSTROUTING -o eth0-j MASQUERADE
sudo hostapd /etc/hostapd.conf
sudo iptables -D POSTROUTING -t nat -o eth0-j MASQUERADE
sudo sysctl net.ipv4.ip_forward=0
sudo service dnsmasq stop
sudo service hostapd stop

• Now, execute the shell script

sh <path to hotspot.sh>

Error:

nl80211: Could not configure driver mode
nl80211: deinit infname=wlan0 disabled_lib_rates=0....

Solution:

airmon-ng check
killall wpa_supplicant
sh <path to hotspot.sh>

A device is connected to the hotspot!!

Cheers !! 🙂
