A simple Programing simulating Emergency services Complaint Registration using TCP sockets. A client contacts a server to get a service(police or medical) and gets connected to the service server to register the complaint.
This python program utilzes AF_INET streaming sockets in other words,it sets up a TCP IPv4 only connections so ensure that the client,server and the service_server processes are all connected within the same netwrok/router.
Also,this code should be able to run in any OS/machine with a built-in python 3.x Interperter it should be noted that it was tested extensively on a GNU/Linux machine having Python 3.8.10 interperter and a Windows 10 Machine.
1.The Client process Establishes a connection with the server processs requesting a paticular Emergency service ("police"/"medical")
2.The server then responds with the I.P and port number which the client uses to contact the requested service
3.The client then connects with the service_server and fills up the data form which is registered as new file in the COMPLAINTS folder
4.The service_server then sends an acknowledgement back to the client and all connections are closed
Please note that the unmodified source code can run only within the same machine but to run it across two or three machines ensure that these programs run within the same netwrok/subnet to do that type open terminal and type ifconfig (or ipconfig on windows command ) and ensure that first 3 octets are same refer to the server.py source code comments and modify accodringly.
1)Download this repo as a zip&extract it or git clone this repository
git clone https://github.com/Fat-Krow/Socket-Programing-using-python.git
2)Create a sub directory/folder inside the downloaded repository called COMPLAINTS
mkdir COMPLAINTS
3)Run the server
python3 server.py
4)Run the Service server
python3 service_server.py
5)Finally run the client
python3 client.py

Here is a helpful vedio to get you started with Socket Programming with python by channel called Tech with Tim https://www.youtube.com/watch?v=3QiPPX-KeSc
I did find it very useful when I started out :)
