![]() ![]() This will tell the firewall to allow that port for remote communication. If it's a VM in the cloud, then make sure you allow it via ufw: $ ufw allow 5001 If you wish to run the server code on a remote machine and not on the local network, then make sure you allow the port on your firewall. I need to go to my Linux box and send an example file: python3 sender.py Learn also: How to List all Files and Directories in FTP Server using PythonĪlright, let me try it on my own private network: C:\> python receiver.py Once that's finished, we close both the client and server sockets. However, we are opening the file as write in binary ( "wb") here and using the recv(BUFFER_SIZE) method to receive BUFFER_SIZE bytes from the client socket and write it to the file. Not entirely different from the client code. # write to the file the bytes we just received # read 1024 bytes from the socket (receive)īytes_read = client_socket.recv(BUFFER_SIZE) Let's create the TCP socket: # create the client socketĬonnecting to the server: print(f" Connecting to ", unit="B", unit_scale=True, unit_divisor=1024) Os.path.getsize(filename) gets the size of that file in bytes that's great, as we need it for showing progress bars in the client and the server. The filename needs to exist in the current directory, or you can use an absolute path to that file somewhere on your computer. # the name of file we want to send, make sure it exists # the ip address or hostname of the server, the receiver We need to specify the IP address, the port of the server we want to connect to, and the name of the file we want to send. Let's start with the client, the sender: import socketīUFFER_SIZE = 4096 # send 4096 bytes each time step Related: How to Organize Files by Extension in Python.įirst, we gonna need to install the tqdm library, which will enable us to print fancy progress bars: pip3 install tqdm Client Code ![]() However, the goal of this tutorial is to transfer files with Python programming language and without any third-party tool. Please note that there are more reliable ways to transfer files with tools like rsync or scp. We will use the socket module, which comes built-in with Python and provides us with socket operations that are widely used on the Internet, as they are behind any connection to any network. On the other hand, the client will try to connect to the server and send a file of any type. The basic idea is to create a server that listens on a particular port this server will be responsible for receiving files (you can make the server send files as well). In this tutorial, we'll go step by step on how you can write client/server Python scripts that handles that.
