How to protect from ARP spoofing

In my campus, some people they are using netcut in Windows and they are blocking us not to use Internet.

Since I am a Ubuntu user, I can't install neither nutcut nor netcut-defender to protect and even I tried TuxCut. It's is also not working properly.

Can any one give me the right solution for this?

Try ArpON, it is already in Ubuntu repository:

sudo apt-get install arpon

sudo arpon -i eth0 -d

• man arpon

Try changing macaddress. It will remove you from the list of the attacker.

• Figure out Network Interface name which connects you to wifi

   sudo ifconfig
  

If ifconfig is not installed

    sudo apt install net-tools

• This will give you a list of network interface card. Some of them are for bluetooth, wifi. Note down the name responsible for wifi connection. For my PC it was wlp3s0

• Now install macchanger

   sudo apt-get install macchanger
  

• Turn off the network interface card

  sudo ifconfig wlp3s0 down
  

• Randomly change macaddress

   sudo macchanger -r wlp3s0
  

• Turn on the network interface card

  sudo ifconfig wlp3s0 up
  

• Turn off wifi and turn it on

Macaddress is changed, internet will work fine. This changes macaddress temporarily. Upon restart you need to change address again.
