It is a powerful tool that requires strong networking knowledge. Administrators use this to detect malfunctioning network devices that drop packets, latency problems caused by machines moving traffic halfway around the world, and the deletion of or even hacking of data. This helps you to track the network traffic and offers tools to search and drill down to the root cause of the problem. Popular troubleshooting issues that Wireshark can support include dropped packages, latent problems, and malicious network activities. You can track network traffic in real-time by using this free program and it is also the best way to troubleshoot issues within your network. Similarly when used on a wireless network, most sniffers can only scan one channel at a time, but the use of multiple wireless interfaces can expand this capability.Wireshark is the leading global network traffic analyzer and an important resource for all safety professionals or system administrators. When used on a wired networks, sniffers might have access to the packets of every connected machine or can be limited by the placement of network switches. Filtered Mode: Only capture packets that contain specific data elements.
Unfiltered Mode: Capture all packets possible and write them to a local hard drive for later examination.It’s possible to configure sniffers in two ways.
These settings allows anyone (eg network engineers or malicious intruders) to examine any packet, regardless of destination.
