- Sockets are low-level networking interfaces between computers. Many programming languages come standard with socket libraries for creating socket connections. In this lab, we’ll study the usage of networking sockets in Python to write a custom client/server program. Client/Server source code as a ZIP or RAR file in D2L Word document outlining the description of your program. The word document should contain screenshots containing your name on the VM and reports of what’s occurring in them. Demonstrate your socket solution accomplishes the following: The client connects to the server Client and server successfully exchange messages Following the TCP stream in Wireshark Identifying the message sent in Wireshark Any additional functionality you created in your solution. please use python.arrow_forwardPlease help with the following: What do the following commands do in the Linux cmd line: rm (-i -R -f)cp (-n -u -i -f -r -p)mv (-n -u -i -f )arrow_forwardWrite socket code to implement the following server/client commination - 1. Client asks the server for current Date and Time within a period of 5 seconds 2. Servers send the current Date and Time to client 3. Client prints the current date and time You MUST use a shared buffer to store the date and time information. There must be at-least 4 clients request to the server. You must use LOCKS to ensure no data corruption. Upload CODE AND OUTPUT SCREENSHOT for this assignment.arrow_forward
