Training Tuesday Edition - 4

This week’s blog presents a set of free, short videos on performing network configuration functions on Oracle Linux 8. Being able to configure networks is an essential skill to access programs, storage and data on remote systems. This video series also covers firewall configuration required to keep your networks safe and secure from intruders.

Oracle Linux 8 handles network communications through software configuration files and the network interface cards (NICs) in your system. NetworkManager is the default networking service in Oracle Linux 8 and includes a command-line tool, nmcli to create, display, edit, delete, activate, and deactivate network connections. You can use the ip command to display the status of a network interface, configure network properties, or for debugging or tuning the network.

A firewall serves as the computer equivalent of a physical wall, gate, or fence to keep intruders out and protect what's inside. The default firewall service in Oracle Linux 8 is firewalld. In Oracle Linux 8, nftables replaced iptables, and firewalld interacts with nftables.

Here’s the list of videos and the time it takes for you to complete each one:

  • video Network Configuration Files on Oracle Linux 8 (7 Min)
  • video Using NetworkManager CLI (nmcli) on Oracle Linux 8 (7 Min)
  • video Using the ip command on Oracle Linux 8 (9 Min)
  • video Introduction to using firewalld on Oracle Linux 8 (8 Min)
  • video Using nftables on Oracle Linux 8 (7 Min)

Be sure to come back for our next edition, which will cover Oracle Ksplice. 

New videos are added on an ongoing basis so check back often.
