Packet Capture

Mobileums dsClient Desktop supports the capture and display of test traffic with the Packet Capture feature. With this feature, test configurations can be created, transmitted to the target servers, the test(s) executed, with capture/collection/display of the messages created by the test, without leaving dsClient Desktop.


Access the Packet Capture workspace from the menu bar: dsTest Servers>Manage><server name>. Click on the Packet Capture tab.


The Packet Capture Workspace window consists of three sections (see image below):

Capture Configuration;

Capture File list;


In the Capture Configuration Section, the following parameters can be configured:

File name – The file name for the capture file;

File count – the number of files to retain with the current capture;

File Size – the maximum size of the capture files being retained for the current capture;

Buffer Size – the size of the buffer to use for collecting capture date for the current capture;

Protocol – SCTP or TCP or UDP (default == any);

Port – Port (socket) to use as the source or destination (default == any);

Capture Count – the number of packet to capture (default: 0 == until current capture is stopped);

Connection – IP Address or Device name on which to capture packets (default == any).

If a capture is currently running on the server, the current capture parameters will be displayed in the Capture Configuration section when the Packet Capture window is opened.

The Capture File List section contains the list of capture files currently in the present working directory (PWD) on the target server. These files can be downloaded to the local disk and opened for display, assuming that a display application, such as Wireshark®, exists and is available on the local client machine.

The PWD of the file list can be modified by entering a pathname in the File Name box. The pathname must have a forward slash (/) character at the end, otherwise it will be interpreted as a file name.

The Operations Section consist of:

Status – retrieves the current capture status from the server;

Refresh File List – refreshes the file list;

Start – Start a capture;

Stop – Stop the current capture;

Download capture file from server;


Capture (Start);



Stream (existing) file.


This feature requires dsFilter to be installed on the server. Contact Mobileum dsTest Support for instructions on how to install  dsFilter on your dsTest server. In order to view the capture files, there must be a display application, such as Wireshark®, resident on the local client machine.
