Network Utilities Welcome back. In this lecture we’ll talk about network utilities. We’ll talk about some of those tools and commands that can help us with troubleshooting. Let’s begin. We’ll talk about six commands in specific. Those commands are telnet, SSH, ping, traceroute, FTP, and file copy. Let’s start with the first one called Telnet. To take a look at the these commands will go straight to the terminal. All right, as you can see, I’m at the terminal. Let’s try the commands one by one. All of these commands…

System and Chassis Information Welcome back. In this lecture, we’ll understand how can we use Show commands to view important system and chassis information. Let’s begin. First, let’s talk about system information. We can use the operational mode Show System command to get system information. I have some important Show System commands listed on the screen right now, such as Show system alarms, shows boot messages, show System commit, showstem connections, show system login lockout, memory storage, uptime users, and so on. The best way to understand this is by…

Summary of Section 4 Hello and welcome back. In this lecture we are going to summarize what we learned in section four. So in section four, we started by talking about initial configuration where we talked about how to set a root authentication password. We also spoke about system services for remote access such as SSH and telnet. We understood how we can set the host name, system time and time zone. We also understood how we can set a login message and how we can configure the command line…

Network Time Protocol Welcome back. In this lecture, we’ll talk about network time protocol. Let’s begin. The first question is what is network time protocol? Network Time Protocol, also known as NTP, is a very widely used protocol which is used to synchronize the clocks of routers and other hardware devices on the Internet. Net debugging and troubleshooting becomes easier when timestamps in the log files of all devices are synchronized. Because events that span the network can be correlated with synchronous entries in multiple logs. Devices running Juno’s can…

Tracing Welcome back. In this lecture we are going to talk about tracing. Let’s begin. All right, so first of all, what do we mean by tracing? Tracing is the juno’s term for what other vendors sometimes call as debugging. When you enable tracing, a trace file is created that is used to store decoded protocols information received or sent by the routing engine. In other words, when you enable tracing, a file is created which contains all the messages captured using the trace function. Juno sends the tracing results…

System Logging Hello and welcome back. In this lecture, we’re going to talk about system logging. Let’s begin. First of all, what do we mean by Syslog or system logging? System logging operations record systemwide highlevel operations such as interfaces going up or down or users logging into or out of the device. By default, logging logs are placed in files that are stored in the VAR log directory. The primary Syslog file which is included in all factory default configurations is the VAR log messages file. Every system log…

Introduction Welcome to the new chapter that is Taste, Tool and Automation. For this particular chapter.  Our discussion points would be tool Selection, tool Lifecycle and Tool Metrics. So let’s try to get into detail one by one. Tool Selection So, how the test tools should be selected and what are the criteria to be kept in mind while selecting the test tools. What are the options available? What is the pros and cons of different types of types of test tools? Let’s discuss all the details in this sub…

Introduction Welcome to the last chapter of the Syllables for ISTQB advanced Level Test Manager Certification. The chapter is about people skills and team composition. Being a test manager, it’s not all about knowing technical details and how something should be done. Manager is someone who manages the team, who builds up the team, who motivates the team and who gets the things done. So let’s see how the manager should work and what are the factors to be considered. Test managers should recruit, hire and maintain teams with proper…

Introduction Welcome to the next chapter and it is about improving the testing process. The discussion points for this chapter are as following once established, an organization’s overall test process should undergo continuous improvement. So this chapter covers generic improvement issues first and then introduction to some specific models which can be used for taste process improvement. Taste managers should assume they will be the driving force behind taste process changes and improvements and so should be familiar with the industry accepted techniques we are going to discuss in this…

Introduction And the chapter we are going to discuss is about defect management. And the discussion points would be to gain insight of status of project and present it in correct way. Two critical factors are defect Management process tool used for management of defects. Taste manager must be familiar with what critical data to capture how to properly use process and selected defect management tool. Defect Lifecycle and Software Development Lifecycle So, before getting into how to manage defects, let’s try to understand the defect lifecycle and the software…
