• Toolbars: Contains essential functions like capturing, stopping, saving, and replaying packets.

Capturing Packets

To start capturing packets:

1. Select the network interface you want to listen to from the interface dropdown menu.
2. Click the Start Capture button.
3. Watch as packets populate in the Packet List in real time.

Analyzing a Packet

1. Click on any packet in the list to view its details.
2. The details pane will unfold, showing you each layer of the packet’s structure.
3. You can expand headers to drill down into specific fields.

Modifying a Packet

To modify a selected packet:

1. Right-click on the packet in the list.
2. Select the option to edit fields or data.
3. Make desired changes and save your modifications.

Tips for Effective Data Manipulation

1. Experiment with Custom Packets: Don’t hesitate to create and experiment with custom packets. Altering headers or payload data can provide insights into network responses.

2. Use Filters: Apply filters while capturing packets to focus on specific types of traffic, which can save time during analysis.

3. Regularly Save Captures: Make it a habit to save your packet captures frequently to ensure you don’t lose any critical data during long sessions.

4. Study Protocols: Familiarize yourself with common protocols through resources or PacketEditor’s built-in documentation. Understanding how protocols operate will enhance your manipulation skills.
