In Ubuntu system, you can use the following command to disable the firewall:

  1. Close the firewall using the ufw command.
sudo ufw disable

After executing this command, the firewall will be disabled.

  1. Turn off the firewall using the iptables command.
sudo iptables -F
sudo iptables -X
sudo iptables -P INPUT ACCEPT
sudo iptables -P FORWARD ACCEPT
sudo iptables -P OUTPUT ACCEPT

After executing the above command, all iptables rules will be cleared and the default rule will be set to allow all traffic.

Please note that disabling the firewall may reduce the security of the system, so make sure there are other security measures in place to protect the system before turning off the firewall.
