The task of determining the ports used, statistics and active TCP / IP connections in the Microsoft Windows operating system can be solved by standard means of the system itself using the netstat console utility.
Instructions
Step 1
Call the main menu of the Microsoft Windows operating system by clicking the "Start" button to perform the procedure for determining the used TCP / IP protocol connections and place the cursor in the "Run" field.
Step 2
Enter the value cmd in the "Open" field and confirm the execution of the command for launching the "Command Line" tool by clicking the OK button.
Step 3
Enter the value netstat -ano in the Windows command interpreter test box and confirm the command by pressing the Enter function key.
Step 4
Remember the syntax for the console command you are using:
- a - display of all used connections and ports;
- n - display not aliases and DNS names, but actual numeric values of ports and IP addresses of connections;
- o - display of PID (Process ID) - digital identifier of the process using this connection or port.
Step 5
Identify the application responsible for the specific connection on the selected port and remember its identifier.
Step 6
Return to the Run dialog and re-enter the cmd value in the Open field to define the required process.
Step 7
Confirm the execution of the command to start the Windows command interpreter by clicking OK and enter the value tasklist | find the saved_PID in the Command Line tool text box.
Step 8
Confirm the execution of the command by pressing the Enter function key or simultaneously pressing the Ctrl + Shift + Esc function keys to launch the built-in Windows Task Manager utility.
Step 9
Go to the Processes tab of the dispatcher dialog box that opens and open the View menu of the top toolbar.
Step 10
Specify the "Select Columns" command and apply the checkbox to the PID (Process Identifier) field.
Step 11
Find the process you want or use the built-in TCPView utility.
