Posted: 2024-03-18 Earlier versions of Red Hat Enterprise Linux (on which AlmaLinux is based) provided two virtualization platforms: Kernel-based Virtual Machine (KVM) and Xen. In recent releases, support for Xen has been removed, leaving KVM as the only bundled virtualization option supplied with AlmaLinux 9. In addition to KVM, third-party solutions are available in products…

Posted: 2024-02-26 Although Linux has made some inroads into the desktop market, its origins and future are very much server-based. It is unsurprising, therefore, that AlmaLinux 9 can act as a file server. It is also common for AlmaLinux and Windows systems to be used side by side in networked environments. Therefore, it is a…

Posted: 2024-02-14 AlmaLinux 9 provides two mechanisms for sharing files and folders with other systems on a network. One approach is to use a technology called Samba. Samba is based on Microsoft Windows Folder Sharing and allows Linux systems to make folders accessible to Windows systems and access Windows-based folder shares from Linux. This approach…

Posted: 2024-02-28 In the previous chapter, we looked at how to display the entire AlmaLinux 9 desktop on a remote computer. While this works well if you need to display the entire desktop remotely, it could be considered overkill if you only want to display a single application. Therefore, this chapter will look at displaying…

Posted: 2024-02-25 AlmaLinux 9 can be configured to provide remote access to the graphical desktop environment over a network or internet connection. Although not enabled by default, displaying and accessing an AlmaLinux 9 desktop from a system anywhere else on a network or the internet is relatively straightforward. This can be achieved regardless of whether…

Posted: 2024-02-22 When an AlmaLinux 9 system is first installed, it is configured by default to allow remote command-line access via Secure Shell (SSH) connections. SSH provides password-protected and encrypted access to the system for the root account and any other users added during the installation phase. However, this level of security is inadequate and…

Posted: 2024-02-14 A firewall is vital in protecting a computer system or network of computers from external attacks (typically from an external source via an internet connection). For example, any computer connected directly to an internet connection must run a firewall to protect against malicious activity. Similarly, any internal network must have some form of…

Posted: 2024-02-14 A firewall is a vital component in protecting an individual computer system or network of computers from external attacks (typically from an internet connection). Any computer connected directly to an internet connection should ideally run a firewall to protect against malicious activity. Similarly, any internal network must have some form of firewall between…

Posted: 2024-02-17 It is difficult to envisage an AlmaLinux 9 system that does not have at least one network connection, and harder still to imagine how such an isolated system could be of much practical use. The simple fact is that AlmaLinux 9 is designed to provide enterprise-level services over network and internet connections. Therefore,…

Posted: 2024-02-05 To gain proficiency in AlmaLinux 9 system administration, it is essential to understand the concepts of systemd units with a particular emphasis on two specific types known as targets and services. This chapter provides a basic overview of the different systemd units supported by AlmaLinux 9 and how to configure the many services…
