Ubuntu open port 8080

Open ports on Ubuntu allow incoming network traffic to reach specific applications or services running on your Ubuntu system. For example, if you want to run a web server on your Ubuntu system, you need to open port 80 or 443 to allow incoming web traffic.

Similarly, if you want to allow remote access to your Ubuntu system via SSH, you need to open port 22.

By default, Ubuntu comes with a firewall called UFW (Uncomplicated Firewall) that blocks all incoming connections. Opening ports on Ubuntu involves configuring the UFW firewall rules to allow incoming traffic to specific ports.
