Source again sent RST, ACK to destinationĪt this point, you can check the network traffic for the close port. Source sent ACK packet to the destinationĤ. Source sent SYN packet to the destinationģ. Also start the Wireshark on the other side to get the package: nmap -sT -p 445 192.168.1.102Īs you can see in the image below, executing the above command indicates that port 445 is open.Īt this point, you can look over the sequence of packet transfer between source and destination captured through Wireshark.ġ. You can type the NMAP command to scan TCP as shown below. Finally, the source again sent RST, ACK packets. After doing this, if the port is open, the source requests with the SYN packet, sends the SYN response destination, the ACK packet, and then the ACK packet source. It should note that this scan ensures listening to the (open) port via a three-way manual connection between the source port and the destination port. TCP Scan scans the TCP port like ports 21, 22, 23, 445. In the following, we will introduce you to the different sections on how to use Wireshark in Nmap. So you can distinguish them by your MAC address. This is common for Windows and Linux devices.
The important point to note in this section is that in this section, work is done with the IP address (192.168.1.102).
