> Groff provides an excellent and fast way to produce nice documents from a flat text file.
> When a Threat Intelligence Management (TIM) license is present in your Cortex XSOAR environment, the feature to create relationships between indicators is available. This allows you to describe how indicators relate to each other and use this relationship in your automated analysis of a security incident.
> In the previous blog post in this series, we gave a brief overview of the additional features available in Cortex XSOAR when a TIM license is imported. We also showed you how to create relationships between indicators from within automations by using the CommandResults class from CommonServerPython.
> In this post, we will show you how to create relationships from within a Cortex XSOAR integration. This requires a different approach because there are different features available in an automation and an integration.
> Monit is an open-source utility program that manages and monitors resources and services on Linux systems. Some services and resources managed by Monit are CPU usage, memory usage, server uptime, network connections, and server application services. It also ensures that all running services are always healthy by restarting services that stop or encounter operating errors such as system downtime, application crashes, or resource spikes. In addition, Monit can also be configured to send alerts to administrators when certain events occur, allowing administrators to take corrective action before problems escalate. As a result, Monit is an essential tool for keeping Linux systems running smoothly.
> In the following tutorial, you will learn how to install Monit on Fedora 36 Linux using the version direct from Fedora’s repository and configure Monit to be accessible from your browser using the command line terminal.
> In this tutorial, we will show you how to install Monit on Fedora 36. For those of you who didn’t know, Monit is an open-source utility for monitoring and managing Unix systems. Monit monitors the server programs to increase service uptime and ensures that they stay online consistently. With Monit, system status can be viewed directly from the command line, or via the native HTTP web server.
> This article assumes you have at least basic knowledge of Linux, know how to use the shell, and most importantly, you host your site on your own VPS. The installation is quite simple and assumes you are running in the root account, if not you may need to add ‘sudo‘ to the commands to get root privileges. I will show you the step-by-step installation of the Monit monitoring tool on a Fedora 36.
> The top command is a Linux command that displays real-time information about your computer’s processes. This information includes how much CPU and memory each process is using. The top command is very helpful when you want to troubleshoot problems with your computer or optimize its performance. While there are many different top commands that can be used on Linux, the most common are ps, netstat, lsof, vmstat, and htop. These top commands can be used to view information about your computer’s processes, view information about your computer’s network connections, view information about open files and the processes that are using them, and more. The specific top command that you use will determine what information you can view.
> in handy when you need to remove directories. Both are part of the GNU core utilities that allow a user to clean their disk space by removing the directories that are no longer needed. While both the utilities allow removing the directories, the rmdir only allows removing “empty directories”. It prevents accidentally removing the non-empty directories. If you try to use the rmdir command to remove a non-empty directory, it will throw the “Directory not empty” error message. If you want to remove a non-empty directory, you can use the rm command.”
> Another thing to remember is that when a file or directory is removed using either the rm or rmdir, it is immediately removed from the system rather than being sent to the Trash. Hence, you must be very careful while using these commands, as you will not be able to retrieve the removed files and directories without a backup.
> In this article, we are going to show how you can use the rmdir command to remove directories in Linux, along with some examples. We have demonstrated the examples on Linux Ubuntu. However, these work the same on every Linux distribution.
> In this section, we will discuss some command line ways to check the OS version in a Linux OS. These commands work for all Linux distributions.
> You can open the Terminal by pressing the super key on your keyboard and then search for it using the search box at the top. When the Terminal icon appears, click on it to open.
> “We all know that a network interface card (NIC) acts as a bridge between a computer system and the network that this system is attached. The NIC has an associated speed which determines the quality of your interaction with the network. Therefore, in this guide, we will try to explore the methods through which we can check the NIC speed in Linux.”
