19CS406-EX-1 STUDY OF SOCKET PROGRAMMING WITH CLIENT-SERVER MODEL

DATE : 09-03-2023

AIM :

To implement socket programming date and time display from client toserver using TCPSockets

ALGORITHM :

Server:

1. Create a server socket and bind it to port.

2. Listen for new connection and when a connection arrives, accept it.

3. Send server‟s date and time to the client.

4. Read client‟s IP address sent by the client.

5. Display the client details.

6. Repeat steps 2-5 until the server is terminated.

7. Close all streams.

8. Close the server socket.

9. Stop.

Client:

1. Create a client socket and connect it to the server‟s port number.

2. Retrieve its own IP address using built-in function.

3. Send its address to the server.

4. Display the date & time sent by the server.

5. Close the input and output streams.

6. Close the client socket.

7. Stop.

SERVER PROGRAM :

import socket
s=socket.socket()
s.connect(('localhost',8000))
print(s.getsockname())
print(s.recv(1024).decode())
s.send("acknowledgement recived from the server".encode())

CLIENT PROGRAM:

import socket
s=socket.socket()
s.bind(('localhost',8000))
s.listen(5)
c,addr=s.accept()
address={"165.165.80.80":"6A:08:AA:C2","165.165.79.1":"8A:BC:E3:FA"};
while True:
    ip=c.recv(1024).decode()
    try:
        c.send(address[ip].encode())
    except KeyError:
        c.send("Not Found".encode())
