Prerequisites Before we dive into packet analysis, make sure you have the following set up: Two Endpoints (VMs or Containers) Wireshark tcpdump It’s also important to have a basic understanding of: TCP SSH Linux Introduction In this blog post, I'll guide you through the step-by-step process of analyzing SSH connection packets using Wireshark. Whether you're troubleshooting SSH issues or simply curious about how SSH works at the protocol level, this tutorial is for you. We'll cover both successful and failed SSH connections, examining the packet flow and explaining what’s happening in the background. I've already set up a working environment for this use case. Let’s dive right into packet capture and analysis, and uncover what happens during an SSH connection. Fig. 1: A list of servers with roles and IP addresses for quick network reference. Breaking Down Packet Capture and Analysis: A Step-by-Step Guide In this post, we'll break down the process of packet capture...

Telnet Under the Microscope: Why It's Unsafe for Modern Use

Telnet, an early protocol for remote server and device access, was once groundbreaking. However, in today’s era of cybersecurity threats, Telnet’s lack of encryption has made it obsolete and dangerous to use. This blog will demonstrate the security risks of Telnet by capturing and analysing its unencrypted communication over a network. We Will: Create two Ubuntu instances using Multipass. Install and configure a Telnet server on one instance. Create a user and password on the server. Capture network packets while authenticating to the server. Analyse the captured packets to show how credentials are sent in plain text. Part 1: Introduction and Setting Up Ubuntu Instances In Part 1 , we start by setting up Ubuntu instances using Multipass . We walk through the process of creating a Telnet server and Telnet client , preparing the environment for the next steps. Watch the video here: In Part 2 , we install and configure the telnetd package on the Telnet server . This is the crucial step...

Working in such a rapidly growing software industry, there are new software and certifications which are announced almost every day. And for every new certification announced, you would think that doing it would be cool or help you in your career. Similarly, I saw some of the certification announcements, which included AWS, Azure, Jenkins, Docker, and Kubernetes certification. My initial thought was that I should do each & every one of them, but time passed by and here I am, with just one and only certification "CKA". This made me realize and question myself if completing a certification is necessary. Decision : Here is my take on it. Holding a certification won’t get you on top of the world, and not holding one will not make you fall. That being said, I enrolled to complete CKA, and here are a few points which made it easier for me to decide. 1. Cost : For some, this may not be the most important, but I still consider if its worth spending 200/300$ for it...
