Mellanox Adds Cumulus Linux Support for Ethernet Switches

Tuesday, March 8th, 2016

SUNNYVALE, Calif. & YOKNEAM, Israel–(BUSINESS WIRE)–Mellanox® Technologies, Ltd. (NASDAQ:MLNX), a leading supplier of high-performance, end-to-end interconnect solutions for data center servers and storage systems, today announced it has added Cumulus® Linux® support for the Spectrum line of 10/25, 40/50, and 100 Gb/s Ethernet switches.

The addition of Cumulus Linux provides customers a best in class Network Operating System (NOS) with the highest performance and most predictable Ethernet switch platform. The availability of third party NOS solutions is the cornerstone of the Open Ethernet initiative and provides customers with freedom of choice. “Mellanox is uniquely positioned to capitalize on a big opportunity as the industry continues to move towards open solutions” Tweet this“The addition of Cumulus Linux means we now give our customers the option to choose the leading Linux NOS on the market,” said Amit Katz, vice president Ethernet switch sales, Mellanox Technologies. “We are confident our Ethernet switch platforms will continue to deliver unmatched predictability, packet performance and the ability to achieve Web-Scale IT efficiencies.”In order to achieve more agile innovation and to avoid vendor lock-in, many of the largest and most advanced web scale businesses have rejected closed, proprietary, black box switches.

Taking a page from these hyperscale data centers, more modestly sized businesses are emulating these architectures and adopting open, disaggregated switches – which separate the choice of hardware and software components. These open networking platforms enable customers to choose best of breed components in order to optimize and automate their data centers to meet their business needs. The fully integrated and tested combination of Spectrum switches and Cumulus Linux is the ideal way to achieve this agility, with an open networking platform that frees enterprises to extend and improve the pace of innovation, efficiency, and automation of their data center infrastructure.Mellanox is helping to accelerate the adoption of open networking and the transformation of businesses to achieve web-scale IT efficiencies.

The partnership between Mellanox and Cumulus Networks is a realization of the Open-Ethernet initiative and furthers both companies’ long-standing commitment to open networking, as demonstrated by their contributions to the Open Compute Project (OCP), Switch Abstraction Interface (SAI), Linux Switchdev, and Open Network Install Environment (ONIE). In addition, Mellanox has made multiple contributions of 10/25, 40/50, & 100 Gb/s Ethernet switch and OCP adapters designs.“Mellanox is uniquely positioned to capitalize on a big opportunity as the industry continues to move towards open solutions,” said JR Rivers, CEO and co-founder, Cumulus Networks. “With Mellanox’s performance-focused value proposition, Open Ethernet initiative, and large base of clients, Cumulus can expand into new markets and help accelerate customers’ move to Web IT. Open is becoming the industry standard at every level in modern infrastructure builds. As ecosystems open up, customers win; all due to selecting the best technology under the best terms.”“At Cloudalize, we offer the GPU Desktop as a Service (GDaaS) Platform to a wide range of partners for the cloud solutions they deliver to their customers, so we demand performance, predictability, and industrial-grade control of our networking equipment,” said Benny Willen, CEO Cloudalize. “Cloudalize’s requirements for high performance networking, that could be provisioned as easily as servers, led us to look at an Open solution in the form of Cumulus Linux running on top of Mellanox’s Ethernet Switches.

With Cumulus Linux, we could leverage many of our server tools to automate our network orchestration and monitoring activities. With Mellanox Ethernet Switches, we get the predictable performance we need, without worrying about packet loss.”Come see how to transform your data center and achieve web-scale IT efficiency with the Cumulus Linux running on the Spectrum switch at the Mellanox booth #B4 at the OCP Summit taking place March 9-10 at the San Jose Convention Center.

​Why has SQL Server come to Linux? Windows-only cloud makes no sense | ZDNet

Tuesday, March 8th, 2016

Some people are asking why. After all, with MySQL, MariaDB, postgreSQL, and Oracle Database 12c Linux, there’s no shortage of RDBMS servers on Linux.Part of the reason is simple enough. Scott Guthrie, head of Microsoft’s Cloud & Enterprise business, said “This will enable SQL Server to deliver a consistent data platform across Windows Server and Linux, as well as on-premises and cloud.The more complex answer is that Microsoft’s fortune is no longer based on Windows. True, SQL Server will be available on Red Hat Enterprise Linux (RHEL) and Canonical’s Ubuntu Linux as a standalone server applications, that’s not where it’s meant to run. As Ed Bott recently uncovered, Microsoft’s new cash cows are Azure and server applications. In particular, “Microsoft Azure is growing rapidly and is reported in the same group as traditional server products (SQL Server is up, Windows Server is down). Collectively, that pair is at the top of the list.”And what operating systems run on Azure? Mark Russinovich, CTO of Microsoft Azure, Microsoft’s cloud program, said last fall that open source and Linux make great financial and technical sense for Microsoft. “It’s obvious, if we don’t support Linux, we’ll be Windows only and that’s not practical.” Then, one in four Azure operating systems instances were Linux. And that number has only been increasing.ADVERTISINGFor Microsoft to continue to grow as a cloud and services company it must become a Linux company.And, in particular, Microsoft wants to be a Linux cloud power. Today, Azure is certainly the primary way Microsoft monetizes Linux, so it’s only logical that SQL Server would be added to Linux.Al Gillen, IDC’s group vice president, sees this. “By taking this key product to Linux, Microsoft is proving its commitment to being a cross platform solution provider. This gives customers choice and reduces the concerns for lock-in. We would expect this will also accelerate the overall adoption of SQL Server.”

Microsoft Open Sources .NET, Saying It Will Run On Linux and Mac | WIRED

Wednesday, November 12th, 2014

Satya Nadella’s rapid reinvention of Microsoft continues.

In yet another bid to make up lost ground in the long march to the future of computing, Microsoft is now open sourcing the very foundation of .NET—the software that millions of developers use to build and operate websites and other large online applications—and it says this free code will eventually run not only on computer servers that use its own Windows operating system, but also atop machines equipped with Linux or Apple’s Mac OS, Microsoft’s two main operating system rivals.

“We want to have a developer offering that is relevant and attractive and valuable to any developer working on any kind of application,” says S. “Soma” Somasegar, the 25-year Microsoft veteran oversees the company’s wide range of tools for software developers.

With the move, Microsoft is embracing the reality that modern software and online services run atop a variety of operating systems—and that Windows no longer dominates the market the way it once did. At least tacitly, the software giant is acknowledging that so many businesses and developers now choose to run their software atop computer servers loaded with the open source Linux operating system, which, in recent years, has evolved in ways that Windows has not. Most notably, it offers what’s called containers, a new means of streamlining the way applications are built and operated.

“Today, people who are stuck on the .NET platform have to use a server environment that doesn’t have what Linux does,” says James Watters, who, at a company called Pivotal, works hand-and-hand with a wide range of developers and companies as they build large online software applications. “They’re stuck with a generation-behind technology.”

For Watters, Microsoft has ample ground to make up. But in opening sourcing what’s called the .NET Core runtime—freely sharing it with the world at large—the company at least gives itself a fighting chance as it seeks to maintain a hold on the way the world builds and runs software.

In theory, an open source .NET that runs on Linux and Mac OS will expand the use of Microsoft’s developer tools. Then the company can pull in revenue through other channels—through premium versions of its developer tools and through its cloud computing service, Microsoft Azure, a means of building and running software without setting up your own servers.

The move is just the latest in a long line of rather large changes Microsoft has made since Nadella took over as CEO in January—all with an eye towards the rise of rival operating systems and open source software. The company now offers free versions of its Office applications for Apple iPhones and iPads. It provides a free version of Windows for phones and other small devices, hoping to catch up with Google’s open source Android operating system. And it says that the next version of Windows for computer servers will run Docker, a hugely important container technology that was originally built on Linux.

All this seemed unlikely under previous CEO Steve Ballmer—and all can help Microsoft find new relevance in the ever-changing world of online computing.

Chasing Java

Among developers and businesses building websites and other large online services, .NET is one of the primary competitors to Java. It’s widely used among companies that rely heavily on Microsoft software —the company says .NET was installed more than 1.8 billion times over the last year—but according to most estimates, Java is still the more popular tool. And many consider it the more powerful.

According to Watters, about 60 percent of Pivotal’s customers built their apps atop Java, about 40 percent on .NET. “Java is the go-to, and .NET is the legacy,” he says.

Google Releases ‘nogotofail’ Network Traffic Security Testing Tool

Google Releases 'nogotofail' Network Traffic Security Testing Tool

Google introduced a new security tool to help developers detect bugs and security glitches in the network traffic security that may leave passwords and other sensitive information open to snooping.

The open source tool, dubbed as Nogotofail, has been launched by the technology giant in sake of a number of vulnerabilities discovered in the implementation of the transport layer security, from the most critical Heartbleed bug in OpenSSL to the Apple’s gotofail bug to the recent POODLE bug in SSL version 3.
The company has made the Nogotofail tool available on GitHub, so that so anyone can test their applications, contribute new features to the project, provide support for more platforms, and help improve the security of the internet.
Android security engineer Chad Brubaker said that the Nogotofail main purpose is to confirm that internet-connected devices and applications aren’t vulnerable to transport layer security (TLS) and Secure Sockets Layer (SSL) encryption issues.
The network security testing tool includes testing for common SSL certificate verification issues, HTTPS and TLS/SSL library vulnerabilities and misconfigurations, SSL and STARTTLS stripping issues, and clear text traffic issues, and more.

Google is committed to increasing the use of TLS/SSL in all applications and services. But ‘HTTPS everywhere’ is not enough; it also needs to be used correctly,” Brubaker wrote in a blog post.

Most platforms and devices have secure defaults, but some applications and libraries override the defaults for the worse, and in some instances we’ve seen platforms make mistakes as well. As applications get more complex, connect to more services, and use more third party libraries, it becomes easier to introduce these types of mistakes.

Nogotofail tool, written by Android engineers Chad Brubaker, Alex Klyubin and Geremy Condra, works on devices running Android, iOS, Linux, Windows, Chrome OS, OS X, and “in fact any device you use to connect to the Internet.” The tool can be deployed on a router, a Linux machine, or a VPN server.
The company says it has been using the Nogotofail tool internally for “some time” and has worked with developers to improve the security of their apps before releasing it. “But we want the use of TLS/SSL to advance as quickly as possible,” Brubaker said.
The Nogotofail tool requires Python 2.7 and pyOpenSSL>=0.13. It features an on-path network Man-in-the-Middle (MiTM), designed to work on Linux machines, as well and optional clients for the devices being tested.

BlackEnergy Cyber Crimeware equipped to Target Linux Systems and Cisco Routers

 

Security researchers at Kaspersky Lab have unearthed new capabilities in the BlackEnergy Crimeware weapon that has now ability to hacking routers, Linux systems and Windows, targeting industry through Cisco network devices.The antivirus vendor’s Global Research & Analysis Team released a report Monday detailing some of the new “relatively unknown” custom plug-in capabilities that the cyber espionage group has developed for BlackEnergy to attack Cisco networking devices and target ARM and MIPS platforms.The malware was upgraded with custom plugins including Ciscoapi.tcl which targets The Borg’s kit, and According to researchers, the upgraded version contained various wrappers over Cisco EXEC-commands and “a punchy message for Kaspersky,” which reads, “Fuck U, Kaspersky!!! U never get a fresh B1ack En3rgy. So, thanks C1sco 1td for built-in backd00rs & 0-days.”BlackEnergy malware program was originally created and used by cybercriminals to launch Distributed Denial-of-Service DDoS attacks. The malware developer then added some custom plugins used to funnel banking information.Most recently BlackEnergy malware was observed in alleged state-sponsored attacks targeting the North Atlantic Treaty Organization NATO, Ukrainian and Polish government agencies, and a variety of sensitive European industries over the last year.Now, the cyber espionage group has enhanced the malware program which also has the capabilities like port scanning, password stealing, system information gathering, digital certificate theft, remote desktop connectivity and even hard disk wiping and destroying.In case if a victim knew of the BlackEnergy infection on their system, the attacker activates “dstr,” the name of a plugin that destroys hard disks by overwriting them with random data. A second victim was compromised by using VPN credentials taken from the first victim.Security researchers, Kurt Baumgartner and Maria Garnaeva, also came across BlackEnergy version that works on ARM and MIPS based systems and found that it has compromised networking devices manufactured by Cisco Systems.However, the experts are not sure for the purpose of some plugins, including one that gathers device instance IDs and other information on connected USB drives and another that collects details on the BIOS Basic Input/Output System, motherboard, and processor of infected systems. “We are pretty sure that our list of [BlackEnergy] tools is not complete,” the researchers wrote. “For example, we have yet to obtain the router access plugin, but we are confident that it exists. Evidence also supports the hypothesis that there is a decryption plugin for victim files.”Multiple unnamed victim companies in different countries were targeted with the latest BlackEnergy malware, including victims in Russia, Germany, Belgium, Turkey, Libya, Vietnam and several other countries.Another Crimeware group, the Sandworm Team, believed to have used the BlackEnergy exclusively throughout 2014 at victim sites and included custom plugin and scripts of their own. Also last month, the Sandworm Team had targeted organizations across the world in an espionage campaign, and iSIGHT Partners revealed that the team used spear phishing as the major attack vector to victimize their targets.

CVE-2014-4877: Wget FTP Symlink Attack Vulnerability

CVE-2014-4877: Wget FTP Symlink Attack VulnerabilityThe open-source Wget application which is most widely used on Linux and Unix systems for retrieving files from the web has found vulnerable to a critical flaw.GNU Wget is a command-line utility designed to retrieve files from the Web using HTTP, HTTPS, and FTP, the most widely used Internet protocols. Wget can be easily installed on any Unix-like system and has been ported to many environments, including Microsoft Windows, Mac OS X, OpenVMS, MorphOS and AmigaOS.When a recursive directory fetch over FTP server as the target, it would let an attacker “create arbitrary files, directories or symbolic links” due to a symlink flaw.IMPACT OF SYMLINK ATTACK “It was found that wget was susceptible to a symlink attack which could create arbitrary files, directories or symbolic links and set their permissions when retrieving a directory recursively through FTP,” developer Vasyl Kaigorodov wrote in a Red Hat Bugzilla comment.A remote unauthenticated malicious FTP server connected to the victim via wget would allow attackers to do anything they wanted. Wget could download and create or overwrite existing files within the context of the user running wget.The vulnerability was first reported to the GNU Wget project by HD Moore, chief research officer at Rapid7. and is publicly identified as CVE-2014-4877. The flaw is considered critical since wget is present on nearly every Linux server in the world, and is installable although not by default on OS X machines as well, so needs a patch as soon as possible.PATCH AVAILABLE “This flaw can lead to remote code execution through system-level vectors such as cron and user-level vectors such as bash profile files and SSH authorized_keys,” Moore wrote.The vulnerability has now been fixed by the Wget project in wget 1.16, which blocks the default setting that allowed the setting of local symlinks. “Upgrade to wget version 1.16 or a package that has backported the CVE-2014-4877 patch,” Moore said.

Ubuntu 14.04 wows through subtlety – TechRepublic

Friday, April 18th, 2014

It’s a rare occasion that a new release of a Linux desktop — especial a new Long Term Support (LTS) — can wow with subtlety. Usually, the releasing entity attempts to change the game with major updated features or complete redesigns. That is not the case with Ubuntu 14.04 (Trusty Tahr).

This time around, Canonical wows us with a subtle makeover. In some cases, the change is almost imperceptible, but it’s there. These subtle changes make Ubuntu 14.04 as polished a distribution as you’ll find. It’s cleaner, performs better, and is all around improved. Some users may say that this is the most boring release Canonical has unleashed in years, but I believe it to be one of the finest.

Let me explain.

Every modern desktop operating system is in a war to win over users. To do this, distributions must not only be highly useable and reliable, but they also have to look professional. It’s one of the issues some of the more fringe Linux desktops have yet to grasp. Users (new users, not those already initiated into the ways of Linux) want to work with a polished and clean desktop that’s worthy of their trust.

Ubuntu 14.04 ‘Trusty Tahr’ Released For ‘Cost-Effective Windows XP Replacement’ – HotHardware

Friday, April 18th, 2014

Linux, and Ubuntu in particular, missed a golden opportunity to truly break into the mainstream market during the early days of Vista. The buggy operating system (prior to SP1) left consumers angry and willing to consider alternatives, but at the time, even Ubuntu was still a little rough around the edges to draw widespread interest among lifelong Windows users. With Canonical’s release of Ubuntu 14.04 (Trusty Tahr) coming hot off the heels of Microsoft discontinuing support for Windows XP, could a mass migration take place?

Hey, anything is possible. And unlike the early Vista era, Canonical is actively chasing Windows users with its latest release.

The 14.04 LTS release offers a solid, intuitive experience which is easy to manage,” Jane Silber, CEO at Canonical comments. “It is a viable and affordable alternative for those organizations considering a switch from Microsoft, and specifically those replacing XP or Windows 7 as they come to the end of life.”

Based on those comments, Canonical is also going after Windows users who don’t like the direction Microsoft took the platform with Windows 8. It’s a bold and aggressive strategy, and you have to give Canonical credit for going about it in a tactful manner — the company isn’t bashing Microsoft or Windows, it’s just pointing out that Ubuntu 14.04 is a cost-effective alternative.

50 Open Source Replacements for Windows XP – Datamation

Friday, April 18th, 2014

Before we get to the list itself, here’s a some quick background for Windows XP users who aren’t familiar with Linux or open source software. Linux is an operating system that anyone can use free of charge. In addition, anyone can see the source code for Linux and modify it however they like. Because anyone can tweak it, it comes in thousands of different versions, which are known as “distributions.” Different Linux distributions use different interfaces or “desktops,” which determine how the operating system looks on the screen. Unlike Windows, Linux distributions generally come with lots of free applications already built in, so users don’t have to pay extra for office productivity software, security software, games or other applications.

Beginner-Friendly Linux Distributions

1. Linux Mint

Many people consider Linux Mint to be among the most intuitive operating systems for Windows XP users. It supports several different desktop interfaces, including Cinnamon, which users can configure to look and feel a lot like XP.

2. Ubuntu

Very easy to use, Ubuntu is likely the most widely used Linux distribution in the world. The desktop version offers speed, security, thousands of built-in applications and compatibility with most peripherals.

 

3. Zorin OS

Built specifically to attract former Windows users, Ubuntu-based Zorin is probably the Linux distribution that’s the most similar to Windows. It includes a unique “Look Changer” that switches the desktop to look like Windows 7, XP, Vista, Ubuntu Unity, Mac OS X or GNOME 2, and it includes WINE and PlayOnLinux to allow users to keep using their Windows software.

4. Robolinux

Also similar to Windows, Robolinux promises to allow users to run all their Windows XP and 7 software without making themselves vulnerable to malware. It also includes more than 30,000 open source applications.

5. StartOS

Formerly known as YLMF, the interface for StartOS looks an awful lot like Windows XP. It’s managed by a group of Chinese developers, so the website is in Chinese. However, English versions of the OS are available.

6. Pinguy OS

According to the Pinguy website, “PinguyOS is very much designed for people who are new to the Linux world; many people coming from both a Windows or a Mac background will find plenty of familiar features along with some new ones that aren’t available in either Windows or Mac.” It’s based on Ubuntu and uses the Gnome-Shell desktop.

7. MEPIS

Popular with new Linux users, MEPIS aims at providing a Linux distribution that’s very stable and very easy to use. It comes with hundreds of applications preinstalled and you can easily dual-boot it alongside Windows so that you can continue using XP software.

8. Antergos

Previously known as Cinnarch, Antergos is based on Arch Linux, which is popular with hard-core open source users, but Antergos much easier for beginners to use than Arch. It comes with a graphical installer that allows the user to choose from among several interfaces, including some that look quite a bit like XP.

9. Manjaro

Like Antergos, Manjaro aims to be a more user-friendly version of Arch. It comes with desktop environments, software management applications and media codecs pre-installed so users can get right to work after installing it.

10. PCLinuxOS

Like many other OSes on this list, PCLinuxOS was designed with usability in mind. It can run from a LiveCD, meaning you can try it out while still keeping Windows XP installed on your PC.

11. Edubuntu

For those looking to replace Windows XP on a PC primarily used by kids, Edubuntu is an excellent choice. It’s based on Ubuntu (and supported by Canonical, the company behind Ubuntu), so it’s very user-friendly. Plus, it adds plenty of software tailored for use by schools or home users with children.

12. Mageia

Forked from Mandrake (which was later renamed Mandriva), Mageia is a community-driven Linux distribution with a good reputation for being beginner-friendly. Because it’s updated very frequently, it tends to include more recent versions of software packages, and it has excellent support for several different languages.

13. OpenMandriva

Like Mageia, OpenMandriva is a community-managed Linux distribution based on Mandrake/Mandriva. It attempts to be simple and straightforward enough for new users but also to offer the breadth and depth of capabilities demanded by advanced users.

14. Kubuntu

Kubuntu’s goal is to “make your PC friendly,” and it’s fairly easy for new Linux users to figure out. It combines Ubuntu and the KDE desktop and includes plenty of built-in software, like a web browser, an office suite, media apps and more.

15. Netrunner

Netrunner is based on Kubuntu, plus some interface modifications to make it even more user friendly and some extra codecs to make it easier to play media files. The project also offers a second version of the same OS based on Manjaro.

16. Kwheezy

Kwheezy is based on Debian, which is popular with advanced Linux users, but it’s designed to be more accessible for Linux newcomers. It comes “with all the applications, plugins, fonts and drivers that you need for daily use, and some more,” and it uses the intuitive KDE desktop.

17. Point Linux

Also based on Debian, Point Linux uses the Mate desktop, which should feel comfortable to most Windows XP users. It aims to be a “fast, stable and predictable” desktop operating system.
