The capture window is shown above in figure 6. The red stop button (as circled in blue below) may be selected at any time when the capturing needs to be stopped:

Enable the checkbox as circled in red below:.The promiscuous mode can be verified as follows: Verifying that the promiscuous mode has been selected:

The promiscuous mode, which is enabled by default, allows all other packets on the same network to be displayed. This is demonstrated in the illustration below: Immediately after the “start capturing” button (as circled in red above) is selected, the packets are displayed in real time. To start capturing data, the application is launched, and an interface is selected as shown below:įigure 1 – Selecting an Interface for Capture Wireshark, formerly known as “ethereal” can be downloaded from This allows a systems administrator to unveil any potential attacks.

This article reviews Wireshark, which is a free and open source packet analyzer used to capture, analyze and filter packets. Network attacks can be identified explicitly by analyzing the incoming and outgoing traffic because unusual behavior comes from suspicious patterns of packets.2 A network troubleshooting software and protocol analyzer would help us to identify any such anomalies. Packets traversing across networks, when seized, unveil their true signature This enables system administrators to take ownership and restore systems from damages caused by attackers. To prevent these network-related attacks, it is necessary to know their origination point. These threats not only affect the users of the systems but the administrators and the forensic investigators themselves. As networks have become more complex, hackers across the globe are launching attacks such as identity/information theft, and machine hijacking.
