Explanation:
To capture packets sent to and received from the URLhttps://www.companypro.net:7100/apiusing Wireshark, you would use the following filter options:
* Protocol:tcp
* Filter Type:port
* Port Number:7100
This filter setup in Wireshark will display all TCP packets that are sent to or received from port 7100, which is the port specified in the URL for the API service. Since HTTPS typically uses TCP as the transport layer protocol, filtering by TCP and the specific port number will help isolate the relevant packets for troubleshooting the app's data download issues.
* cp: The app is using HTTPS, which relies on the TCP protocol for communication.
* port: The specific port number used by the application, which in this case is 7100.
* 7100: This is the port specified in the URL (https://www.companypro.net:7100/api).
This filter will capture all TCP traffic on port 7100, allowing you to analyze the packets related to the application's data download.
