Hottest Releases of This Week

Which guy is hottest? At this week, Red Hat based distributions gets new updates. CentOS is most popular Linux distribution as a completely free for RHEL. New release has published two days ago. The new release is contains of some major changes. Some packages are deprecated on this release as well.

CentOS 7-1810

Newest version of CentOS has been rebuild from RHEL 7.6 source codes. The following is the major changes which comes with CentOS 7-1810:

  • Since release 1503 (abrt>= 2.1.11-19.el7.centos.0.1) CentOS-7 can report bugs directly to bugs.centos.org. You can find information about that feature at this page.
  • Among others, the following packages have received rebaseing to more current upstream versions: samba, pki-core, gcc-libraries, elf-utils, GNOME shell, X11-server, ipset, firewalld, gnutls and libreswan.
  • SSL-cpabilites have been added to Net::SMTP.
  • Open-JDK-11 is now available.
  • pNFS SCSI is no longer a Technology Preview.
  • Thunderbolt-3 interfaces are now supported.
  • As always – various driver updates.
  • The following packages have been declared deprecated: Python 2, lvm2app, 3DES as part of Python, signtool, sendmail, dmraid, Btrfs filesystem, several rsyslog options, various drivers and others. More information can be found in the RHEL 7.6 Release Notes.
  • If you plan to use Security Profiles in Anaconda, please see this link.
  • ipset users should note that as part of the above mentioned rebase, the location of saved ipset data has changed from /etc/sysconfig/ipset to /etc/sysconfig/ipset.d/ and the new directory now contains one file per saved ipset. Users with configuration management that sets up /etc/sysconfig/ipset will need to modify their setup.

Scientific Linux

Scientific Linux is a clone from Red Hat Enterprise Linux same as CentOS. This week Scientific Linux 7.6 has been released. The major changes are same as changes on Red Hat Enterprise Linux 7.6.

Proxmox VE

Proxmox VE (Virtual Environment) 5.3 has been released. Here are the highlights of the new version 5.3:

  • Based on Debian 9.6 and Linux Kernel 4.15
  • You can create CephFS and the Metadata servers (MDS) in the GUI
  • Improved disk management: add ZFS raid volumes, LVM, and LVMthin pools
  • ZFS over iSCSI storage plug-in can access LIO target in the Linux kernel
  • LXC: nesting is enabled for containers – you can use LXC or LXD inside a container
  • PCI passthrough and vGPUs via GUI
  • Countless bugfixes

Arch Based Linux

Arch Linux is most updated Linux distribution. There is some Arch based distributions such as SwagArch and BlackArch. These two distributions has new release this week. SwagArch is a GNU/Linux desktop distribution based on Arch Linux. The SwagArch distribution features a live DVD that runs the Xfce desktop and uses the Calamares graphical system installer. SwagArch offers popular FOSS applications pre-installed, including Firefox and the VLC multimedia player.

BlackArch Linux is an Arch Linux-based distribution designed for penetration testers and security researchers. It is supplied as a live DVD image that comes with several lightweight window managers, including Fluxbox, Openbox, Awesome and spectrwm. It ships with over a thousand specialist tools for penetration testing and forensic analysis.

Security Distributions

This week, VyOS 1.2.0-rc10 and pfSense 2.4.4-p1 have been released. VyOS is a community fork of Vyatta, a distribution discontinued in 2013. It is a network operating system that provides software-based network routing, firewall and VPN functionality. VyOS is based on Debian GNU/Linux and is completely free and open-source. Its features include the ability to run on both physical and virtual platforms, and support for para-virtual drivers and integration packages for virtual platforms.

pfSense is a free, open source customized distribution of FreeBSD specifically tailored for use as a firewall and router that is entirely managed via web interface. In addition to being a routing platform, pfSense includes a long list of related features and a package system which allows further expandability.

BSD Based

DragonFly is an operating system and environment designed to be the logical continuation of the FreeBSD-4.x OS series. These operating systems belong in the same class as Linux in that they are based on UNIX ideals and APIs. DragonFly is a fork in the path, so to speak, giving the BSD base an opportunity to grow in an entirely new direction from the one taken in the FreeBSD-5 series. DragonFly 5.4.0 has been released this week.

FreeNAS is a tiny FreeBSD-based operating system which provides free Network-Attached Storage (NAS) services (CIFS, FTP and NFS).

These major features are new in the 11.2 series:

  • The login screen defaults to the new, Angular-based UI. Users who wish to continue to use the classic UI can select “LEGACY WEB INTERFACE” in the login screen.
  • Beginning with this release, there are two published versions of the 11.2 User Guide: one contains the screenshots for the new UI using the default dark theme and the other contains the screenshots for the legacy UI. The availability of both versions of the Guide is to assist users as they become familiar with the new UI during the transition period before the legacy UI is deprecated in a future release. Both versions contain a menu selector, making it easy to navigate between different versions of the Guide.
  • The rewrite from the old API to the new middlewared continues. Once the API stabilizes and the rewrite is complete, freenas.org will be deprecated and replaced by the new API documentation. In the mean time, to see the API documentation for the new middleware, log into the new UI, click on the URL for the FreeNAS system in your browser’s location bar, and add /api/docs to the end of that URL.
  • The boot loader has changed from GRUB to the native FreeBSD boot loader. This should resolve several issues that some users experienced with GRUB. GRUB was introduced as a temporary solution until the FreeBSD boot loader had full support for boot environments, which it now has.
  • The Plugins and Jails backend has switched from wardento iocage and warden will no longer receive bug fixes. The new UI will automatically use iocage to create and manage Plugins and Jails. Users are encouraged to recreate any existing Plugins and Jails using the new UI to ensure that they are running the latest supported application versions.
  • Virtual Machines are more crash-resistant. When a guest is started, the amount of available memory is checked and an initialization error will occur if there is insufficient system resources. When a guest is stopped, its resources are returned to the system. In addition, the UEFI boot menu fix allows Linux kernels 4.15 and higher to boot properly.
  • Cloud Sync Tasks provides configuration options to encrypt data before it is transmitted and to keep it in the encrypted format while stored on the cloud. The filenames can also be encrypted. Additionally, support has been added for these providers: Amazon Cloud Drive, Box, Dropbox, FTP, Google Drive, HTTP, Hubic, Mega, Microsoft OneDrive, pCloud, SFTP, WebDAV, and Yandex.
  • Support has been added for Self-Encrypting Drives (SEDs).
  • OpenZFS is up-to-date with Illumos and slightly ahead due to support for sorted scrubs which were ported from ZFS on Linux. Notable improvements include channel programs, data disk removal, more resilient volume import, the ability to import a pool with missing vdevs, pool checkpoints, improved compressed ARC performance, and ZIL batching. Note that many of these improvements need further testing so have not yet been integrated into the UI.

FreeBSD is most popular BSD based. This week, FreeBSD 12.0-RC3 has been released. This version is still release candidate (RC).

HardenedBSD 1100056.10 has been released. HardenedBSD is a security-enhanced fork of FreeBSD. The HardenedBSD Project is implementing many exploit mitigation and security technologies on top of FreeBSD. The project started with Address Space Layout Randomization (ASLR) as an initial focal point and is now implementing further exploit mitigation techniques.

Cloning!

Clonezilla Live is a Debian-based live CD containing Clonezilla, a partition and disk cloning software similar to Norton Ghost. It saves and restores only used blocks in hard drive. With Clonezilla, one can clone a 5 GB system to 40 clients in about 10 minutes.

  1. Great post David. I’m sure I’m not the only one concerned about the CentOS/Red Hat relationship now that IBM is in the picture…

    1. Thanks. I guess, IBM has plan for some Red Hat’s products such as OpenShift.
      About RHEL, if IBM does any action, it has a lot of consequences.
      ِDon’t forget, even IBM has to fight with Oracle!
