Tcp File Server Client

Clientserver implementation in C sending datafilesI am not an expert in network so I will comment on the part that doesnt interest you that much. On top of that, your code is pretty clean, well documented and seemed to work properly when I tried it locally so there is not too much to say. You should try to avoid magic numbers to keep things maintainable and any other kind of hardcoded data in the middle of the code. You could put server and client in the same file in different methods. You have unused variable. An easy way to notice it is to try to put declaration as late as possible, in the smallest possible scope and as close to their first use as possible. Also, compiler warnings might help you.

Python Tutorial Network Programming Server Client B File Transfer. Note. In this chapter, were going to extend Python Network Programming I Basic Server Client A, and try to file transfer from a server to numerous clients. The main purpose is to check the performance of the server from which clients download files. Local file transfer. Here is the code to send a file from a local server to a local client. Import socket module. Reserve a port for your service. Create a socket object. Get local machine name. Bind to the port. Now wait for client connection. Server listening. Establish connection with client. Got connection from, addr. Server received, reprdata. Sent ,reprl. l f. Done sending. conn. Thank you for connecting. Import socket module. Create a socket object. Get local machine name. Reserve a port for your service. Hello server. with openreceivedfile, wb as f. True. printreceiving data. Successfully get the file. Output on a local server. Server listening. Got connection from 1. Server received, Hello server. Sent, 1 1. 23. Sent, 4. Sent, 3. 00 1. Output on a local client. Thank you for connecting. Successfully get the file. Our server code above can only interact with one client. If we try to connect with a second client, however, it simply wont reply to the new client. To let the server interact with multiple clients, we need to use multi threading. Here is the new server script to accept multiple client connections. Thread. from Socket. Server import Threading.

Below is the output from the server console when we run two clients simultaneously. Waiting for incoming connections. Got connection from 1. New thread started for 1.

In the following codes, we made two changes ip switched to amazon ec. To calculate the time to take download a file, we import time module. EC2 instance. from threading import Thread. Socket.

Download time vs number of clients. Here is the output showing the wall clock time depending on the number of concurrent connections Our server is located in California, and the following picture compares the download speed between US and Japan Python Network Programming.
