Last week, Red Hat released version 7.3 of her Enterprise Linux. CentOS builds will follow soon. There are a number of features introduced as Technology Preview. The complete release notes can be found on the Red Hat website.
- The SELinux userspace has been rebased and provides various enhancements and performance improvements. Notably, the new SELinux module store supports priorities, and the SELinux Common Intermediate Language (CIL) has been introduced.
- OpenSCAP workbench now provides a new SCAP Security Guide integration dialog and enables modification of SCAP policies using a graphical tool.
- The OpenSCAP suite now includes support for scanning containers using the atomic scan command.
- Upgraded firewalld starts and restarts significantly faster due to a new transaction model. It also provides improved management of connections, interfaces, and sources, a new default logging option, and ipset support.
- The audit daemon introduces a new flush technique, which significantly improves performance. Audit policy, configuration, and logging have been enhanced and now support a number of new options.
- Media Access Control Security (MACsec) encryption over Ethernet is now supported.
I’m busy with the training and certification for Red Hat Enterprise Linux 7. Many things changed in the new release of Red Hat Linux. IPtables is replaced by Firewalld, UPstart is replaced by systemd and the ext4 file-system by xfs. The problem: good documentation isn’t available in books. However, online there are tons of documentation. One of my favorites: certdepot.net.
This website doesn’t only include documentation but also daily lab-exercises that are mandatory to pass the RHCSA or RHCE exams since these are hands on instead of multiple choice questions. Sorry braindump fellows out there. These will not help you. Hands on experience is mandatory in order to separate the wheat from the chaff. Without this, you won’t pass the exams.
My RHCSA exam is planned for August. RHCE will follow later. There were no options to take the exam earlier in the Netherlands due to the holiday season.
Update: another website to help you: Tecmint.com.
Update: Passed RHCSA on 12/aug/2016. Next: RHCE (but time…).
