A number of challenges are designed around IoT devices that will require a hotspot to be set up this guild will help you setup your hotspot.
NOTE SSID overlap:
*highly recommended* that as a player you should use either a kali virtual machine or the kali live option for the game, as toolset available in kali will meet the requirements of this years challenges. Its also a requirement for some of the IoT Challenges that a bridged wifi network between the IOT device and their vpn to the game network be created. This can easily be accomplished from kali by connecting to the team vpn and then creating a hotspot with the provided USB wifi adapter.
Make sure that the virtual USB port in your virtual machine configuration is USB2.0 standard. If you are using VirtualBox you will need to install the Oracle VM VirtualBox Extension Pack to get USB2.0
- The default SSID is the system hostname so anyone using kali live in the same area will have the same ssid of ‘kali’
- So players in close proximity will need to change their
Hotspot SSID to prevent overlap.
- This can be done by editing the
/etc/NetworkManager/system-connections/Hotspot file or by running the
nmtui command and editing the HotSpot configuration.
Kali has a good built in hotspot from network manager that does not require a lot of changes to use, Once the hotspot is created you will have the to connect the IOT device to that hotspot.
- Connect the wifi dongle to the vm
- Using the network manager: (top right select click on the wifi icon or press windows type "Network" select the entry with the folder and wifi icon)
- on the left select "Wi-Fi"
- click the 'use as HotSpot...'
- click 'Turn On'
- add the wifi information to your esp8266
- Manually setting up a hotspot
- open a terminal and type (navigate using the arrow keys and enter and tab, etc)
- Under 'wifi' select ‘Hotspot’ then click edit Or Add 'Hotspot' under ‘WiFi’
- Under the General tab:
- Tick all users many connect to this network
- Under Wi-Fi Tab:
- SSID = ‘anything’
- Mode = Hotspot
- Band = Automatic
- MTU = Automatic
- Under security:
- Security = WPA & WPA2 personal
- Password = ‘anything’
- IPv4 settings tab:
- Method = Shared to other computers
- IPv46 settings tab:
- Save settings
Hotspot not starting:
- If when you try and start a hotspot and it does nothing.
- Check your
/var/log/syslog If the follow message is there:
kali gnome-control-c: Failed to add new connection: (2) A 'wireless' setting with a valid SSID is required if no AP path was given.
Then you will need to restore the default Hostspot Config
Default Kali Hotspot config:
