The last version under the old naming scheme is CentOS 8, which was released in September 2020, and updates for it end Dec. 31, 2021, a major cut to the update window. There are RHEL training classes on Java, OpenShift, Ansible, OpenStack, and containers, among other topics.

  1. CentOS has the ability to load RHEL 8-compatible software and use the Enterprise Linux (EPEL) packages/repositories because it has a great degree of RHEL compatibility.
  2. If you are already familiar with Linux and like having full control and no cruft to get in your way, then Debian is a great way to go.
  3. There is not a significant amount of default software included in the RHEL distro other than the Firefox web browser.
  4. CentOS is a fully dual-protocol OS with IPv6 installed and enabled by default.
  5. Monitors the current bandwidth utilization across multiple network interfaces.
  6. Networking—The default network interfaces are ens33, virbr0, and virbr0-nic.

Linux OSes can use different default filesystem types, with ext4 and xfs being common among popular Linux distros. When it comes to networking, most Linux OSs use NetworkManager, support DHCP for IPv4 and DHCPv6, SLAAC with RDNSS/DNSSL, and natively support IPv6. The best approach would be to use either an old laptop and install Debian based Linux on it or to buy a single board computer such as the Raspberry Pi. Having access to the actual hardware gives you the opportunity to “mess around” with more aspects of the system.

Assembles and analyzes TCP/IP packets, sends packets to a remote host, and examines the responses. Establishes the connection to the remote server or system through a TCP/IP network using the Telnet protocol. Maps IP addresses to MAC addresses on a local network and manages the ARP cache.

Security—During the installation process, a root password and a standard non-privileged user account was created, and that user was automatically added to the sudoers list. The SSH daemon was not installed and running by default so we had to add it before we could SSH into the OS. Fedora uses SELinux for Mandatory Access Control (MAC) host OS security, and it is in Enforcing mode by default.

I would recommend it to those interested in learning about Linux, on a budget, but want a simple, yet modern, GNOME desktop experience. Licensing and support—RHEL is available via subscription that entitles the user to support, with several different options available. Self-support gives users access to download and run RHEL and access to the Red Hat knowledge base. Standard support adds daytime access to Red Hat engineers for technical support, and premium support provides 24-hour technical support for the most severe issues. The “iwconfig” command is allows you to view and configure the wireless network interfaces.

How to Install Linux

Different Linux distributions have different support and license models. As a distribution designed for penetration testing, Kali Linux comes with a massive variety of preinstalled tools that network engineers are certain to find useful. Use case—Ubuntu is one of my favorite Debian OSs that has a solid community of support. It is the extremely popular, de facto OS for network engineers, and has a broad application package to choose from.

CentOS uses Network Manager for network interface configuration, but Netplan can be enabled and is installable with Snap. After installation completed, the size of VM without its ISO file was 14.5 GB while the root partition disk usage is 4.57 GB. Use case—RHEL is recommended for commercial enterprise-production applications where technical support is required to keep the mission-critical systems running. It is the best Linux OS for running production applications requiring high availability using the most stable OS.
