Socket Programming

Requirements:

• Python installed on your system.

Setting up the Environment:

1. Make sure you have the Python client and server files ready to be executed.
2. Ensure that you have a network connection available between the client and server if they are on different machines.
3. If you are using different machines, use the IP address connected to the network.

Running the Server:

1. Open the terminal or command prompt.

2. Navigate to the directory that contains the Python server file using the cd command, for example:

   cd socket-python
   

3. Next, execute the server file using the following command:

   UDP:

   python udp_server.py
   

   TCP:

   python tcp_server.py
   

   The Python server will start and begin listening for UDP packets or TCP client connections, depending on the file you executed.

Running the Client:

1. Open another terminal or command prompt. Make sure it is on a different machine from the server if possible, or open 2 terminals or command prompts.

2. Navigate to the directory that contains the Python client file using the cd command, for example:

   cd www/networking/socket/python
   

3. Next, execute the Python client file using the following command:

   UDP:

   python udp_client.py
   

   TCP:

   python tcp_client.py
   

   The Python client will connect to the server and initiate communication.

Communication between Client and Server:

• After running the client and server, the communication between them will be established.
• Check the available files: small.txt, medium.txt, large.txt.
• Enter the name of the file you want to receive.
• Finally, a brief description of your request will appear on the screen.

Ending the Execution:

• To terminate the client or server, you can press Ctrl + C in the terminal where they are running, or type 'bye' to exit the application.
• Make sure to terminate the server before closing the client.
