This was a great tutorial, I love how you explained each step and each function and parameter, this is exactly what I was looking for and struggling with the most. Thank you so much dude!
Excellent video and explanation... I am new to network programming but grasped this very quickly bcz of the easy way of explaining each and every step.
I love you really, I figured how this works after a couple days searching for that clear explaintation. Sadly you dont have videos how to implement crash fault tolerance, reliable ordered multicast, voting and dynamic discovery of hosts :(
Thank you for this video! Very easy to understand for python n00bs like myself. I had a few questions if you have the time; 1. Is there a way to eliminate the senders typed message, to prevent it from doubling on the senders screen? 2. Is there a way to prevent user messages that are posted when you are typing from showing up in the message you are writing? 3. Any possibility of a follow up vid with login/encryption? :D Again, thank you.
Thanks a lot , appreciate it 😊 Regarding the first 2 questions; we can absolutely tweak in the code to hide messages ( sender/receiver ) to avoid double appearance but this was just for demonstration purpose :) As far as a follow up video for a login mechanism, I can’t promise in the near future but I’ll add it to my YT projects list :)
It says established connection with so and so but immediately shows error in alias.recv and the error is "An existing connection was forcibly closed by the remote host"
Yes i did I didn't reply earlier because i don't want to sound stupid infront of you so i made my search. Turns out i forgot to start the client thread because i didn't add receive_thread.start() at the client side
Thank you, Justin. Yes, you need to call 2 methods whenever you want to shut down the server : shutdown() and close(). You can create a function and call it at the end of your code block : def terminate(): server.shutdown(socket.SHUT_RDWR) server.close() Don’t forget the indentation in terminate() function
Hi Daniel ! Your question is a tough one 😄 There will be a lot of caveats to tackle down the road : 1- some configuration on the router of the computers on that other LAN . The reason is that nowadays everybody has a public IP address that is provided by your ISP ( internet service provider) This IP address is not fixed, but it is easy to lookup what is ur ip (whatismyip.com) 2 - sending is not going to be a problem, but receiving is. Some service providers like here in Poland don't allow just any port to be used and you have to find out which ports are allowed. The well known ports are most likely not allowed. That for instance makes it impossible to host a webserver without first contacting your ISP. It’s really not easy and require some experience in networking I’ll try in the future to answer your question with a live demo using sockets in python - thanks for your question, Daniel

i ran this once and it was running perfectly but now i keep getting this error (OSError: [WinError 10048] Only one usage of each socket address (protocol/network address/port) is normally permitted) whats that about?
Very nice ! But does anyone know why I don't get the chat updated in my git bash window(s)? They only update if I (from this git bash window) write a message. ... One of my clients is started in pycharm. There I have live chat update the way the git bash instances have it in the video.
@@BekBrace Yes, let's say I have three clients 1. "Git Bash A Client", 2. "Git Bash B Client" and 3. "Pycharm Client" (which only means this time I run the code directly in pycharm and not from git bash or cmd line or so). And the server is of course running. Problem is: "Git Bash A Client" sends message: Despite of the broadcast functionality of the server, only my "Pycharm Client" directly sees the message. "Git Bash B Client" is not updated with the text sent by "Git Bash A Client". But obviously anywhere in the background of "Git Bash B Client" the message must have been received because when I now send a message from "Git Bash B Client" the moment I press "ENTER" the old messages appear. I mean it's not really relevant for what I want to do but I asked my self what's the problem here...Maybe my git bash Version. I don't know. Best regards from MUC, GER

@@BekBrace Hi thanks for the reply. But I cannot host it on my machine/router due to the way my ISP works. Incomming connections will never reach my router as a result. What I am looking for is a cloud solution. I have experience with deploying a C# webAPI to Azure (app service) but it seems that a TCP server like this, is not that easy!
Hi man, my two questions may seem dumber than the others which have been asked. For creating this chatroom, I don't need a Python server like on PythonAnywhere, OpenShift, and all the other Python servers hosting services, right? And this chatroom only works for people on my LAN or on my own PC only? Because I can see it running on localhost
Hey Tech Tok. As far as I'm aware this is very easily done using Django channels. Unfortunately, I don't have django channels course or tutorial on the channel, but I might consider doing one just to show you how to connect a client - client or to disconnect a client from the chatroom
I doubt that , the core nature of tcp and udp is totally different, because udp doesn’t establish a connection before data is sent while tcp is connection focused protocol
This works only on localhost, it's not publicly available. I've answered this question many times, so one of my answers was : There will be a lot of caveats to tackle down the road : 1- some configuration on the router of the computers on that other LAN .

What's your point (if you have any?) and what does neurlanine mean ? In any case, this is the standard setup for multiple clients consumption and one local server in Python.

It says established connection with so and so but immediately shows error in alias.recv and the error is

Have you tried to search for that error on the internet in stack overflow or Google ?
Yes i did
I didn't reply earlier because i don't want to sound stupid infront of you so i made my search.
Turns out i forgot to start the client thread because i didn't add receive_thread.start() at the client side
Talk about not wanting to sound stupid 🤣
@@Majed_ashraf I have receive_thread.start() in my code but im still getting that same error message
This tutorial has been very helpful, but I can't figure out how to shut the server down. Do you have any advice??

Yes, you need to call 2 methods whenever you want to shut down the server : shutdown() and close().

Nice Tutorial. Is it possible for clients to connect with different ips?

The write thread glitches on my end, was there an update recently that possibly caused this? When ran on my raspberry pi, it crashes
Hey. As far as I know, no updates, but I don't think that running on pi would cause a crash; do you get an error message of some sort ?
What do I need to put on the client file if the server is on another computer on the same wifi network ?
