copying same file name from client to server using tcp protocol with same size of file

Question

This is the client and server program where a client sends a file to server to save in the server. There is a issuse in that same file name is not getting copied on the server with same file size

Please help me in this

Client program

import socket
import sys


s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect(("localhost",9999))
path=raw_input("Please enter the complete PATH of your file :  ")
f=open (path, "rb") 
l = f.read(256)
while (l):
    s.sendall(l)
    l = f.read(10000)
s.close()

Server Program

import socket
import sys

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.bind(("localhost",9999))
s.listen(10) 

while True: 
    s, address = s.accept()

    print address
    i=1
    f = open( str(i),'wb') #open in binary
    #i=i+1
    while (True):       

        l=s.recv(256)
        #while (l):
        f.write(l)
        l=s.recv(256)
        print 'File recieve succesfully'
f.close()
#sc.close()
s.close()

Thanks in advance

Start by walking through the code and thinking about what the client knows about the data it is sending and what the server knows about the data it is receiving. You will have to send 2 types of messages: the data and the filename. How you do that is up to you.

Without over-thinking it, maybe try writing the filename first (followed by a newline or special character) then send the file data. On the server side accept the connection, read in data until you find a newline character (that's the filename), then receive the rest of the data and write it to the file.

Also, the server code you've provided doesn't work, at least I don't think, since you never break out of your while True loops.
