LayerView

LayerView is a lightweight packet sniffer whose purpose is to help you keep an eye on data that your computer is sending and receiving.

The layout looks user-friendly and reveals information about the Low Level and TCP/UDP Conversations. You can easily switch between the aforementioned features.

Plus, the tool displays information about the packet, time, protocol, source and destination MAC addresses, source and destination IP addresses, as well as source and destination port. All of these details are recorded in the Low Level panel, while the Conversations window reveals data about the protocol, local and remote address, local port and remote port.

If the layout embeds too many features that you do not actually use, you can opt for hiding the data link, network, transport and application layers.

LayerView gives you the possibility to enable the packet tracing mode by selecting the network interface card whose traffic you want to monitor.

The program is able to reveal detailed information of every packet which your NIC sends and receives. You can select a packet from the list in order to perform an in-depth analysis, namely the protocols that are in use and a thorough examination of the entire packet contents in both hex-dump and text formats.

What’s more, you are allowed to view all conversations which were captured for any of LayerView’s supported protocols, filter packets by setting up rules, as well as save any packet trace to a file so you can easily import in your future projects.

Last but not least, the tool lets you set up rules for coloring the text and background when a received packet matches a custom expression, perform name lookups (convert IP addresses into their associated host names), use promiscuous mode in order to collect sent/received data by other users on the network (useful for wired connections), and specify the read packet buffer value.

In conclusion, LayerView comes with a handy suite of features and delivers an intuitive environment for helping you check out the TCP/UDP conversations for browsing, analyze various protocols and filter data.
