Hi, welcome to my blog 👋

I’m Gabriel, a Systems Engineering student and Network engineer. I’ve started this blog as a hobby, this is a place where I can keep all my study notes, write about whatever I want and share the knowledge I gain during my study sessions and work experience. Hope you like it!

    Hey there! Welcome to my blog! This is the third blog of a series of blog posts I’ve been doing so if you haven’t had the chance to check the other parts, I started this series here and the second part is here. In the last part of the series we configured the Apache web servers, SSH, FTP and the database server with all its components. In this tutorial we’ll be configuring the load balancer and then we’ll configure the web app that shows us the site that we want so play some music, grab something to drink and follow along!

    Hello! Welcome to another blog post :) in this one, I’ll be sharing one project that I did at school and really liked. If you are interested in knowing how you could have a highly available website and want to do it, follow along! Just as an fyi, this doesn’t mean that this is what all data centers have, I am a student, I am learning and this was just for fun.

  7. The network layer

    Third post of the TCP/IP blog series. Here I’ll be summarizing the 4th chapter in the book “Computer networking: a top down approach”. I’ve used some of the images from it to illustrate my point here. I do not own any of the content and all credits go to both authors of this great book. Without further ado, here’s the blog post. What's forwarding? Packet forwarding is taking a packet from an incoming interface and moving it to it’s outgoing interface (if there is one).

  9. The transport layer

    Following up on my “Computer networking: a top down approach” summaries, this blog entry will be about the transport layer. Hope you like it! The transport layer is the layer that sits in the middle of the network layer (where IP addresses live) and the application layer, which we discussed in the previous post. The transport layer gets a message from the application layer through its socket API and encapsulates it into a segment.
