How To Install pcapdiff on Fedora 34
Introduction
In this tutorial we learn how to install pcapdiff
on Fedora 34.
What is pcapdiff
Pcapdiff is a tool developed by the EFF to compare two packet captures and identify potentially forged, dropped, or mangled packets. Two technically- inclined friends can set up packet captures (e.g. tcpdump or Wireshark) on their own computers and produce network traffic between their two computers over the Internet. Later, they can run pcapdiff on the two packet capture files to identify suspicious packets for further investigation. See Detecting packet injection and EFF’s Test Your ISP Project for more background.
