Capture Filters: Use this area to filter the captured packets based on specific criteria (e.g., protocol, source/destination IP address, port number).
Packet List: Displays a list of captured packets, showing their source and destination addresses, protocol, timestamp, and other information.
Packet Details: This section provides detailed information about the selected packet, including its header fields, payload, and decoded content.
Protocol Trees: This visual representation of the network protocol stack helps you understand how packets are constructed and processed.

Packet Details: Click on any packet in the list to view its detailed information.
Protocol Trees: Use the protocol tree to visually analyze the packet structure and the protocols involved.

Tips for Using Wireshark on Ubuntu

Capture Filters: Use capture filters to focus on specific traffic of interest. For example, tcp.port == 80 will capture only packets related to HTTP traffic on port 80.
Display Filters: Use display filters to narrow down the displayed packets after capture. For example, ip.addr == 192.168.1.1 will show only packets involving the IP address 192.168.1.1.
Packet Color Coding: Wireshark uses color coding to identify different types of packets, making it easier to analyze the traffic.
Exporting Data: You can export captured packets to various formats, such as CSV, XML, and JSON.
