Common use cases for PCAP-over-IP include: Transmitting captured network traffic in real time to one or more remote machines; Transferring network traffic to other applications on the same host; Providing decrypted traffic from a TLS interception proxy to a packet analyzer or IDS.
In computer networking, port knocking is a method of externally opening ports on a firewall by generating a connection attempt on a set of prespecified closed ports.

xplico -m pcap -d /path/dir/ in all cases the data decoded are stored in the a directory named xdecode. With the parameter -m we can select the "input module" type. The input module named rltm acquires the data directly from the network interface, vice versa the input module named pcap acquires data form pcap files or directory.
