Why is tcpdump better than Wireshark?
Furthermore, Wireshark helps you to separate streams, such as an entire TCP session’s chat. Tcpdump is most commonly used for system-based traditional interfaces. On the other hand, Wireshark maps Additional network interfaces. Tcpdump only provides do a simple analysis of such types of traffic, such as DNS queries.
Why would you use Tshark over Wireshark?
Even though both tools are almost equivalent in traffic capturing functionality, tshark is a lot more powerful. The best you can do is to use tshark to set up a port in your server that forwards information to your system, so you can capture traffic for analysis using a GUI.
