The release of the NethServer 7.7 distribution, offering a modular solution for the rapid deployment of servers in small offices or medium-sized enterprises, is presented. The distribution is based on the CentOS 7.7 package base and provides a web-based interface for managing available server components. The size of the installation image is 1.1 GB. An online demo is provided to familiarize yourself with the capabilities of the interface. Project developments are distributed under free licenses.

The user is offered ready-made modules for organizing the work of the mail server (Postfix, Dovecot, Amavis, ClamAV + Roundcube web client), collaboration system (SOGo), firewall (Shorewall), web server (LAMP), file server and Active domain controller Directory (Samba), filtering proxy (Squid, ClamAV and SquidGuard), VPN server (OpenVPN, L2TP), cloud storage (ownCloud), intrusion detection and prevention systems. Installation and commissioning of the required service is carried out in one click and does not require knowledge of the configuration features of each server component. Typical administration work can be done through the web interface.

Key innovations:

  • The new user interface, built on the basis of Cockpit and offering a more modern design, has moved to the beta testing stage and is included in the default delivery. Previously installed systems can test the interface by installing Server Manager in the Software Center. The interface provides tools for managing accounts, DNS, DHCP, FQDN, setting the time, creating backups, setting up the network, applying TLS encryption, managing the system, installing applications, managing storage and SSL certificates;
  • A new interface for setting up a VPN, which allows you to evaluate traffic for each tunnel, track the connection history of each user and quickly send connection parameters by email. Through the interface, you can also define your own routes, change the UDP / TCP protocol, activate or disable the account;

Oracle to Release Unbreakable Kernel R5U3

The update for the kernel, that can be used as alternative for Red Hat Enterprise Linux used in the Oracle Linux is based on the Linux 4.14 
25 March 2020   182

Oracle has released the third functional update for the Unbreakable Enterprise Kernel R5 kernel, positioned for use in the Oracle Linux distribution as an alternative to the regular kernel package from Red Hat Enterprise Linux. The kernel is available for x86_64 and ARM64 architectures (aarch64). Kernel sources, including breakdowns into individual patches, are published in the public Oracle Git repository.

The Unbreakable Enterprise Kernel 5 package is based on the Linux 4.14 kernel (UEK R4 was based on the 4.1 kernel), which is supplemented with new features, optimizations and fixes, as well as tested for compatibility with most applications running in RHEL and specially optimized for working with industrial software and Oracle hardware. Installation and src packages with the UEK R5U1 kernel are prepared for Oracle Linux 7 (there are no obstacles to using this kernel in similar versions of RHEL, CentOS and Scientific Linux).

Key improvements:

  • Improved support for 64-bit systems based on the ARM architecture. Updated drivers for ARM.
  • InfiniBand includes on-demand paging support, which allows you to reflect memory through a processor for accessing unallocated pages of memory (page faults), i.e. consume memory when it is actually being used.
  • In XFS, a deadlock was eliminated, which caused the locks to freeze and not free.
  • CIFS resolved an issue that could lead to POSIX lock leaks and crashes.
  • Bug fixes resolving issues with incompatibility of certain equipment with QEMU / KVM.
  • Device drivers are synchronized with the Linux kernel 4.14.35. The driver for Broadcom Emulex LightPulse Fiber Channel SCSI has been updated to version 12.2.0.13.
