Many books and other resources on system administration for Red Hat products are available. Red Hat does not endorse any of these materials as preparation guides for exams. Nevertheless, you may find additional reading helpful to deepen your understanding.
Completely updated for this second edition, Dennis Matotek takes you through an infrastructure-as-code approach, seamlessly taking you through steps along the journey of Linux administration with all you need to master complex systems. This edition now includes Jenkins, Ansible, Logstash and more.
He is a contributor to a number of open source projects and regularly speaks on topics related to writing, systems administration, and open source technologies. He is the author of three books, Pulling Strings with Puppet: Systems Administration Made Easy (Apress, 2008), Hardening Linux (Apress, 2008), and Pro Nagios 2.0 (Apress, 2006).
Just like any other typical operating system, Linux has all of these components: kernel, shells and GUIs, system utilities, and an application program. What makes Linux advantageous over other operating system is that every aspect comes with additional features and all codes for these are downloadable for free.
This is a free eBook to download from GNU. As the name suggests, it deals with Bash Shell (if I can call that). This book has over 175 pages and it covers a number of topics around Linux command line in Bash.
I know that this is a good collection of free Linux eBooks. But this could always be made better. If you have some other resources that could be helpful in learning Linux, do share with us. Please note to share only the legal downloads so that I can update this article with your suggestion(s) without any problem.
The Linux administrator is the common point between the organization and the customer. The professional performs monitoring, partitioning, replication, load balancing, system administration, and performance tuning as well. They also have to conduct root cause analysis to prevent the recurrence of problems.
The contents of the module "The GNU/Linux operating system", of which this book is the main documentation, are mostly related to systems administration. Students will learn how to install, configure and optimise a GNU/Linux operating system and the most widely used computer services.

Starting with v2.1.0, XClarity Administrator utilizes Windows UpdateXpress System Packs (UXSPs) to enable the update of the OS device drivers on deployed Windows operating systems. Windows UXSPs contain Windows device drivers for supported Windows versions and for Lenovo servers that supports Windows. You can download or import Windows UXSPs in the repository. UXSPs must be available in the repository before you can update Windows device drivers on managed severs.
This download provides Lenovo XClarity Administrator base functionality plus a 90-day trial evaluation licenses for XClarity Administrator features Configuration Patterns and bare metal operating system deployment.
Within Lenovo XClarity, you can manage the firmware updates repository and apply and activate firmware updates for managed endpoints. Compliance policies can be started to flag managed endpoints that do not comply with the defined firmware rules. Refreshing the repository and downloading updates requires an Internet connection. If Lenovo XClarity has no Internet connection, you can manually import updates to the repository. The firmware apply and activate interface is shown in the following figure.
Note: The free downloads for both XClarity Administrator and XClarity Integrators do not include any entitlement for technical support. To gain entitlement for technical support, you will need to purchase a license for Lenovo XClarity Pro per physical managed device.
When you purchase XClarity Pro, the order is fulfilled via electronic software delivery (ESD) using the Lenovo Key Management System (LKMS). The order is placed onto LKMS using an email address for the end user who has ordered the code. This email address is where the Activation Code is sent in PDF format (the email will come from firstname.lastname@example.org). The recipient email address is the login to the LKMS system for administration and to manage the LKMS inventory.
For more information on how to redeem the Authorization Code, downloading the XClarity Administrator License key, and importing the license key into the XClarity Administrator appliance, refer to Installing the full-function enablement license in the online help.
Licenses are installed using a license activation key file, in .KEY format or as a .zip file (which consists of multiple .key files). After you redeem licenses, you can create an activation key for all or a subset of your available licenses (Note this can only be done at the time of redemption), and then download and install the activation key in XClarity Administrator per instructions as described in Installing the full-function enablement license in the online help.
Once downloaded, you'll need to put it in your USB. You can use the Fedora Media Writer program to do that. Download and install the application on your system. Now connect your USB drive and open the application:
Reflector can generate a list of mirrors based on a plethora of given constraints. For example, I want a list of mirrors that were synchronized within the last 12 hours and that are located either in India or Singapore (these two are closest to my location), and sort the mirrors by download speed.
I would like to clarify that this list of seven packages is not something mandatory. To have a functional Arch Linux installation, you just need the base, linux, and linux-firmware packages. But considering you'll need the other ones anyway, why not catch 'em all in one go.
The useradd command lets you create a new user. Make sure to replace my name with the one you want to use. The -m option indicates that you also want it to create the corresponding home directory. The -G option will add the new user to the wheel group which is the administration user group in Arch Linux.
There are hundreds of open-source tools that any cybersecurity professional would consider useful as part of their security toolkit. Some are useful within all areas of cybersecurity (analysis, response, forensics or administration), while others may be useful in a single area. Many come pre-installed on security-focused Linux distributions such as Kali Linux, while others can be installed as necessary.
Steve logs into his computer with a privileged account, checks his email, and inadvertently downloads a virus. Since Steve is a member of the DA group the virus has full rights to his computer, all servers, all files, and the entire domain. This could cause serious damage and result in critical systems going down.
Steve checks his email and inadvertently downloads a virus. The virus has limited access to the computer and no access to the domain or other servers. This would cause minimal damage and prevent the virus from spreading through the network.
A user with local admin rights has full access to the entire Windows Operating system. This can lead to all kinds of security issues, such as installing software, disabling antivirus, downloading and installing malware, stealing data, hacking credentials, pivoting to other computers, and so on.
