To disable Firewall in Ubuntu OS

To disable the firewall on Ubuntu, you can use the ufw (Uncomplicated Firewall) command-line tool. Here's how you can disable the firewall:

1. Check Firewall Status (Optional):

   You can check the current status of the firewall to confirm whether it's enabled or disabled. Use the following command:

   sudo ufw status

   If the firewall is enabled, you'll see a message indicating that it's active.

2. Disable Firewall:

   To disable the firewall, you can use the following command:

   sudo ufw disable

   You'll see a message confirming that the firewall has been disabled.

3. Verify Firewall Status (Optional):

   After disabling the firewall, you can verify the status again using the sudo ufw status command to ensure that it's now inactive.
