1. Write python program which create TCP connection between server and client and do the following: (You need to use datetime, hashlib, random modules) 1.1. When the client connect to a server, it will send one of the following commands (time, md5 STRING, random) 1.2. The server will receive the command and based on the command will send back data to the user: 1.2.1. Time: the server will send back the current time using the datetime module. 1.2.2. MD5: the server will take the string along with the md5 word and calculate the MD5 value for it and then send the hash to the client. 1.2.3. Random: the server will generate a random number between 1,100 and will send it back to the user. 2. Check server.py and client.py code and answer the questions below. # Client from socket import * s = socket(AF_INET, SOCK_DGRAM) host = '127.0.0.1' port = 1234 buf =1024 addr = (host,port) req = input("Enter the filename and the line number needed separated by comma: ") #Example: req = 'book2.txt, 5' s.sendto(req.encode('ascii'), addr) print("Data requested.") data, addr = s.recvfrom(buf) print(data.decode()) s.close() # Server from socket import * host = '127.0.0.1' port = 1234 s = socket(AF_INET,SOCK_DGRAM) s.bind((host,port)) addr = (host,port) buf=1024 data,addr = s.recvfrom(buf) data = data.decode() data = data.split(',') f = open(data[0],'r') lines = f.readlines() index = int(data[1]) - 1 s.sendto(lines[index].encode('ascii'), addr) s.close() 1 - What modification(s) can you do to the code #1 and code #2 to make the server and client use the TCP Protocol? 2 - Modify the server code to send an error to the client if the file requested does not exist. 3 - Modify the server code to send an error to the client if the line requested does not exist. 4 - Modify the client code to request the first line if the client didn't write a line number in their request. Example req = 'book2.txt
