Wireshark (old name is Ethereal) is a program that can run in many operating systems such as Windows, Linux, MacOS or Solaris and can analyze all the traffic going to network cards connected to computer. Analyze over 750 protocols Can capture packets and save them to a file.
Logical operators are available for all filtering.
Example: http & ip.src == 192.168.0.1
Management Frame: The frame for the connection between the network device and the client.
Control Frame: Controls the integrity of data traffic between the network device and the client.
Data Frame: The frame on which the original data is transferred.
