Graphical User Interface

The GUI is composed of two tabs: the connection tab and the message tab.

Connection tab

The connection tab contains a list of all connections captured by TProxy. Double-clicking on a connection displays its corresponding captured packets in the message tab.

Connection tab

Message tab

The message tab is composed of four main areas, as described below:

Message tab

  1. The text field is used to enter a new filter, which can then be used as one of the three filter types (explained in 4). The two buttons on the right respectively forward and discard a selected packet that was intercepted with an interception filter.
  2. The main table in the middle of the window displays a list of captured messages.
  3. The bottom pane is composed of three tabs that display the selected packet content: a text editor, a hexadecimal editor and the packet's dissection tree. A more detailed description of each tab is included below.
  4. The leftmost column contains one pane per filter type (for more details about filters, see TProxy Overview ). One can use the filter entered in the text field as a capture, interception or script interception filter using the corresponding "+" button.

Editors

The text and hexadecimal editors display the selected packet content as text and hexadecimal digits respectively. They also allow the user to modify the content of a packet that was intercepted with an interception filter. The modified packet can then be forwarded to its destination with the Forward button.

Dissection tree

When dissection is enabled (default), the dissection tab displays the dissection tree corresponding to the selected packet, which facilitates packet monitoring and editing. One can indeed double-click on a specific field in the dissection tree to retrieve the corresponding bytes in the hexadecimal editor.
