Announcement of RHEL 9 courses

MUK Training Center – Red Hat Advanced Training Partner, Authorized delivery partner – is pleased to announce the start of set for authorized courses according to RHEL 9:

12-16.09.2022 – Red Hat System Administration I (RHEL9) (RH124)

26-30.09.2022 – Red Hat System Administration II (RHEL9) (RH134)

10-14.10.2022 – RHCSA Rapid Track Course (RH199)

Here’s what’s new in RHEL 9 that you can now find covered in Red Hat Training courses:

Installation and Registration

• Simple Content Access changes subscription management, removing many tasks related to preparing registered systems.
• Cloud Access methods, images and registration training content have been created to aid in the understanding of how to deploy simple RHEL instances to the cloud.
• Kickstart has been simplified and enhanced, with training updated to conform to new procedures and syntax.

Software Management

• Training courses will start using DNF commands to replace YUM commands.  YUM is still supported.

Networking

• Network teams are deprecated. The teamd service and the libteam library are deprecated in RHEL 9 and will be removed in the next major release. Our courses will revert to teaching network bonding instead.
• All firewall infrastructure based on iptables has been removed. The ability to migrate iptables configurations to NFT has been removed. Our courses will teach the standard NFT structures and methods.

Security

• SSH root access is now disabled by default.  RHEL 9 adds the following new options to the root password configuration screen:
  • Lock root account: To lock the root access to the machine
  • Allow root SSH login with password: To enable password-based SSH root logins.
• Support for disabling SELinux through /etc/selinux/config has been removed.  With this release, support for disabling SELinux through the SELINUX=disabled option in the /etc/selinux/config file has been removed from the kernel. When you disable SELinux only through /etc/selinux/config, the system starts with SELinux enabled but with no policy loaded.

Storage

• The exFAT filesystem is now supported in RHEL 9. This filesystem is used for external USB storage and interoperability and  data exchange with other operating systems, especially Windows.
• VDO management is now built into LVM. Volume management discussions will be updated to new syntax.

Containers

• Containers and tools were added in the most recent update to RH134, and the content remains valid. Podman now supports secure short names, which can be used in our examples.

Important! A 15% discount is available to all registered for RHEL 9 courses.
