A small HTTP debug server in Go

Posted on August 31, 2018

Lately, I found myself to work on an application that was communicating via SOAP with a server. My goal was to understand how this application worked with the SOAP server to emulate its behavior. Even if I had access to the source code of the application, I thought it would have been easier, faster and more fun to do the work without actually reading the code. It’s important to note that actually, the application is fairly small and self-contained.

libVirt on Hetzner

Posted on April 26, 2017

After many years of using Hetzner as a server provider, and having rented from them multiple servers for many reasons, I decided to rent a server with 128Gb of RAM to do some tests with many (virtualized) machines on top of CentOS. As it often happens, hosting providers put in place a lot of security measurements that sometimes make doing simple stuff more complex. The first approach I tried was using the (only) Ethernet interface as a bridged interface, but that did not brought me very far.

The Wireshark Field Guide by Robert J. Shimonski (Elsevier)

Posted on April 2, 2014

I usually don’t start with this, but lately I had some time constraints that made me wondering if is right to use so much time reading books. The Wireshark Field Guide Analyzing and Troubleshooting Network Traffic by Robert J. Shimonski is only 149 pages long (if we cut the introduction, indexes, etc. it boils down to 128 pages). This is a really short book and I have really appreciated this fact.

Exam Ref 70-413: Designing and Implementing a Server Infrastructure by Steve Suehring (Microsoft Press)

Posted on January 29, 2013

I come to this book less than a month after reviewing the 70-410 Exam Ref. As the title may suggest, this book is tailored to the preparation of the Microsoft 70-413 exam. Speaking of the exam, I have to advice that the book does cover any exam objective, but does not cover every exam question. The book is split into an introduction, 5 chapters and the index. The first chapter helps to understand how to plan and deploy a server infrastructure.

CompTIA Network+ Training Kit (Exam N10-005) by Craig Zacker (Microsoft Press)

Posted on January 1, 2013

Reading this book has helped me a lot understanding better how the networking works. This book is tailored for the CompTIA Network+ certification (and this led me to this book instead of another one, since I’m looking forward to take this certification. I really liked the “structureness” of this book. After a brief introduction (Chapter 1) the book author analyzes the whole networking stack starting from ground up. The first chapters, in fact, are about Physical layer (Chapter 2), Data-Link Layer (Chapter 4) and Network Layer (Chapter 6).
