In this tutorial, I am going to introduce useful pcap manipulation tools and show their use cases. If pcap files are used as part of penetration testing or any kind of offline analysis, there's often need for manipulating pcap files before injecting them into the network. When it comes to storing packet dumps, libpcap's packet dump format ( pcap format) is the most widely used by many open-source packet sniffing and capture programs. If you are a network admin who is involved in testing an intrusion detection system or network access control policy, you may often rely on offline analysis using collected packet dumps.
