Operating system commands.
– Windows:
Use the “netstat” tool on the command line to display all ports and their statuses. You can filter results for a specific port with the command netstat -an | find "Puerto".

– Linux:
Use commands like "lsof" (list open files) or "netstat" to get detailed information about ports and the processes using them.

Graphic tools.
– Operating system utilities:
On both Windows and Linux, you can access graphical tools like Resource Monitor in Windows or System Monitor in Linux to view network activity and ports used.

– Third-party applications:
There are numerous third-party applications, such as “CurrPorts” on Windows or “Netstat Viewer” on Linux, that provide user-friendly graphical interfaces for viewing and managing port activity.

Firewalls and antivirus.
– Personal firewalls:
Check your personal firewall settings to make sure the port in question is allowed and not blocked.

– Antivirus software:
Some antivirus programs also include firewall features. Make sure that your antivirus is not blocking the port you need to use.
