Analyzing network traffic with Tshark
Conclusions
The Tshark analyzer is a simple, command-line tool for monitoring and analyzing data streams. Tshark filters out individual protocols from the array of packages with just a few simple steps.
Tshark is easy to use and learn, and, like its GUI-based counterpart Wireshark, it works well on a small scale. However, sooner or later, Tshark will impair system performance if you need to collect large volumes of data. See the Wireshark wiki [14] for some tips on mitigating any performance slumps that occur when you are using Wireshark or Tshark.
