In Ubuntu Linux, the firewall is managed by the UFW (Uncomplicated Firewall) service. To disable the firewall, you can stop the UFW service and then disable it from starting automatically at boot time.
Here’s how you can disable the firewall in Ubuntu Linux:
- Stop the UFW service:
sudo systemctl stop ufw
- Disable the UFW service from starting automatically at boot time:
sudo systemctl disable ufw
Note: Disabling the firewall can make your server vulnerable to security threats, so it’s recommended to only do this temporarily, and then re-enable it when you’re finished. Also, make sure to take proper security measures, such as securing your SSH access and keeping your software up-to-date.
