D46 #100DaysOfCode. We have communication baby! I finally got my server and client to talk to each other of separate devices.

We have communication!

So I’ve been working on trying to learn Python sockets, and how to make a simple chat application where I can send a message from one device to another.

I first started with running both the client and server locally on the one machine, this worked fine.

I started facing issues when I tried to point a separate device to the server via an IP address, I would just keep getting a connection refused message.

Now my issue was that I was telling the client to connect to 192.168.1.222 which is my internal IP but I was setting the IP of the server to “localhost”. What I thought would happen is that localhost would resolve to it’s IP address, but I should have known better.

So after making that change from localhost to the actual IP address of my PC I started up the client script on my Raspberry PI and started the server script on my PC and BAM! Connection baby!

In doing this, I am actually pretty confident in setting this up without any documentation now so I definitely got something out of it. I went from not knowing anything about sockets to making this. I’m pretty happy about that.
