Interacting with Remote Systems

Inspecting SAMBA packets

If we capture the SMABA packets on port 445 , then we can see how the Windows
Server communicates with the Linux SAMBA client over the CIFS protocol.
In the following two screenshots, a detailed communication between the client
and the server, has been presented. The connection setup has been shown in the
following screenshot:
