Question

TCP client and server using C programming

I am having trouble on how to read in the IP adress and port number from the terminal

Example: Enter IP address: 127.0.0.1

Enter Port Number: 8000

in both client and server code. How do can I make I can assign the Ip address and port number using the example above.

the error I get is that the client couldn't connect with the server whenever i get the port number from the user in the terminal

Answer 1

BELOW IS THE PYTHON IMPLEMENTATION OF SOCKET PROGRAMMING FOR BOTH CLIENT AND SERVER

CLIENT SIDE:

import socket

port=8000

s=socket.socket( socket.AF_INET,socket.SOCK_STREAM,0 )
s.setsockopt( socket.SOL_SOCKET,socket.SO_REUSEADDR,1 )

s.connect(( '127.0.0.1' ,port ))

while 1:
        print("client>>\n")

        msg=raw_input()

        if msg=="quit":
                break

        s.send(msg)
        

        data=s.recv(50)

        print(data)

        if data=="quit":
                break   


s.close()

SERVER SIDE:

import socket

port = 8000

s = socket.socket( socket.AF_INET,socket.SOCK_STREAM,0 )
s.setsockopt( socket.SOL_SOCKET,socket.SO_REUSEADDR,1 )

s.bind(( '',port ))
s.listen( 5 )

print(" i am the Server !, May I help you ?!")
conn, addr = s.accept()

while 1:
        data = conn.recv(500)

        print("Client >> " + str(data))

        msg = raw_input()
        msg = "Server >> " + msg
        conn.send(msg)
        if data == "quit":
                break
        if msg == "quit":
                break

conn.close()
