python3-impacket 0.9.20-5 (amd64 binary) in ubuntu focal

 Impacket is a collection of Python3 classes focused on providing
 access to network packets. Impacket allows Python3 developers to
 craft and decode network packets in simple and consistent manner. It
 includes support for low-level protocols such as IP, UDP and TCP, as
 well as higher-level protocols such as NMB and SMB.
 .
 Impacket is highly effective when used in conjunction with a packet
 capture utility or package such as Pcapy. Packets can be constructed
 from scratch, as well as parsed from raw data. Furthermore, the
 object oriented API makes it simple to work with deep protocol
 hierarchies.
