    Manually create a hotspot in your linux(debian) machine :


Install hostapd(hotspot server) and dnsmasq (dns dhcp server) : sudo dhclient eth0 or sudo dhclient wlan0


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 : sudo gedit /etc/dnsmasq.conf


paste the code below :
  # 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 : sudo gedit /etc/hostapd.conf


paste the code below :
  interface=wlan0
  driver=nl80211
  ssid=JackSparrow
  hw_mode=g
  channel=11
  wpa=1
  wpa_passphrase=test12345
  wpa_key_mgmt=WPA-PSK
  wpa_pairwise=TKIP CCMP
  wpa_ptk_rekey=600
  macaddr_acl=0


You should change the ssid and wpa_passphrase to your preferences


Create hotspot.sh file :sudo gedit hotspot.sh


paste the code below :
    #!/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 hotspot.sh
