Posted by Avik Sarkar On 11/30/2013 03:32:00 am

Red Hat Inc Announced The General Availability Red Hat Enterprise Linux (RHEL) 6.5 

The RHEL 6x series get another important update as Red Hat Inc, the world's leading provider of open source solutions announced the general availability of Red Hat Enterprise Linux 6.5, the latest version of Red Hat Enterprise Linux 6. According to the official press release of Red Hat -RHEL 6.5 expands Red Hat’s vision of providing an enterprise platform that has the stability to free IT to take on major infrastructure challenges and the flexibility to handle future requirements, with an extensive partner and support ecosystem. 
Red Hat Enterprise Linux 6.5 is mainly designed for those who build and manage large, complex IT projects, especially enterprises that require an open hybrid cloud. From security and networking to virtualization, Red Hat Enterprise Linux 6.5 provides the capabilities needed to manage these environments, such as tools that aid in quickly tuning the system to run SAP applications based on published best practices from SAP.“Red Hat Enterprise Linux 6.5 provides the innovation expected from the industry’s leading enterprise Linux operating system while also delivering a mature platform for business operations, be it standardizing operating environments or supporting critical applications. The newest version of Red Hat Enterprise Linux 6 forms the building blocks of the entire Red Hat portfolio, including OpenShift and OpenStack, making it a perfect foundation for enterprises looking to explore the open hybrid cloud.”-said Jim Totton, vice president and general manager of Red Hat Inc. Now lets take a closer look to the main highlights of RHEL 6.5 : 

Securing the Next-Generation Enterprise
Red Hat Enterprise Linux 6.5 continues the push for integrated security functionality that combines ease-of-use and up-to-date security standards into the platform. The addition of a centralized certificate trust store enables standardized certificate access for security services. Also included are tools that meet leading security standards, including OpenSCAP 2.1, which implements the National Institute of Standards and Technology’s (NIST’s) Security Content Automation Protocol (SCAP) 1.2 standard. With these additions, Red Hat Enterprise Linux 6 provides a secure platform upon which to build mission-critical services and applications.

Networking – When Every (Micro)Second Matters
In the financial services and trading-related industries, application latency is measured in microseconds, not seconds. Now, the latest version of Red Hat Enterprise Linux 6 fully supports sub-microsecond clock accuracy over the local area network (LAN) using the Precision Time Protocol (PTP). Precision time synchronization is a key enabler for delivering better performance for high-speed, low latency applications. Red Hat Enterprise Linux 6.5 can now be used to track time on trading transactions, improving time stamp accuracy on archived data or precisely synchronizing time locally or globally. Thanks to other networking enhancements in Red Hat Enterprise Linux 6.5, system administrators now have a more comprehensive view of network activity. These new capabilities enable sysadmins to inspect IGMP (Internet Group Management Protocol) data to list multicast router ports, multicast groups with active subscribers and their associated interfaces, all of which are important to many modern networking scenarios, including streaming media.

Virtualization Enhancements
Red Hat Enterprise Linux 6.5 continues Red Hat’s commitment to improving the overall virtualization experience and includes several improvements that make it a compelling choice for running in virtualized environments. Sysadmins can now dynamically enable or disable virtual processors (vCPUs) in active guests, making it an ideal choice for elastic workloads. The handling of memory intensive applications as Red Hat Enterprise Linux guests has also been improved, with configurations supported for up to 4TB of memory on the Kernel-based Virtual Machine (KVM) hypervisor. The KVM hypervisor also integrates with GlusterFS volumes to provide direct access to the distributed storage platform, improving performance when accessing Red Hat Storage or GlusterFS volumes. Finally, guest drivers have been updated to improve performance of Red Hat Enterprise Linux 6.5 running as a guest on supported third-party hypervisors.

Evolving Ease-of-Use, Storage, and More
As application deployment options grow, portability becomes increasingly important. Red Hat Enterprise Linux 6.5 enables customers to deploy application images in containers created using Docker in their environment of choice: physical, virtual, or cloud. Docker is an open source project to package and run lightweight, self-sufficient containers; containers save developers time by eliminating integration and infrastructure design tasks. Red Hat Enterprise Linux 6.5 stays current with the advancements in Solid-State Drive (SSD) controller interface, introducing support for NVM Express (NVMe)-based SSDs. The NVMe specification aims to standardize the interface for PCIe-based SSDs and its inclusion in Red Hat Enterprise Linux 6.5 positions the platform to support an expanding range of future NVMe-based devices.

Improvements have also been added to improve enterprise storage scalability within Red Hat Enterprise Linux 6.5. It is now possible to configure more than 255 LUNs connected to a single iSCSI target. In addition, control and recovery from SAN for iSCSI and Fibre Channel has been enhanced, and updates to the kexec/kdump mechanism now make it possible to create debug (dump) files on systems configured with very large memory (e.g. 6TB).

Red Hat Enterprise Linux 6.5 makes it easier to track and manage subscription consumption across the enterprise, integrating subscription tracking into existing business workflow. Usability enhancements include support for remote access to Windows clients and servers that use a newer version of the RDP protocol, including Windows 7 and 8 desktops and Windows Server 2012.

"CloudOpen" Open-source Cloud Conference Will Be Hosted By Linux Foundation on August

Posted by Avik Sarkar On 4/29/2012 04:32:00 pm

"CloudOpen" Open-source Cloud Conference Will Be Hosted By Linux Foundation on August
The Linux Foundation announced that it would hold a symposium on the cloud, big data and open source this August in San Diego dubbed CloudOpen. Topics like Hadoop, Gluster, Chef and KVM -- in addition to Linux -- are to be on the menu, as the event aims to inform developers and IT operations personnel alike.
Amanda McPherson, vice president of marketing and developer services for the Linux Foundation, said that the free exchange of ideas is a crucial concern for the community.
"This conference is built on one belief: open works. We know this from experience and know that the cloud demands it in order to be successful for the long term. Because Linux, open-source software and collaborative development are the foundations of the cloud, it's important to provide a vendor-neutral forum where those who are committed to openness can advance this work and users and industry can learn about 'open' as it is related to the cloud," she stated.
The foundation also released a call for proposals, asking that submissions be made by June 1. While there were a couple of seemingly high-profile absences from the announcement -- both Canonical and VMware are nowhere to be found on the official statement -- Linux Foundation communications director Jennifer Cloer says the organization is in talks with both companies and that both are expected to participate in CloudOpen.
The announcement comes at a crucial time for VMware and Canonical, as the latter firm is planning to make waves of its own with the official release of Ubuntu 12.04 later this week and the former battles an increasingly clouded public perception in the open-source sector. The foundation has confirmed that Canonical will be a founding sponsor of CloudOpen.

Microsoft Gets Recognition Among Top 20 Linux Kernel Contributors

Posted by Avik Sarkar On 4/06/2012 10:19:00 pm

Microsoft Gets Recognition Among Top 20 Linux Kernel Contributors

The Linux Foundation announced the top Linux kernel development contributors, with Microsoft getting on the list for the first time. The top 10 contributors to the Linux kernel in this latest report include "Red Hat, Intel, Novell, IBM, Texas Instruments, Broadcom, Nokia, Samsung, Oracle and Google," according to the report. For the first time, Microsoft has made the list of the top 20 contributors to the Linux kernel. Microsoft placed at No. 17 among companies that have contributed the most toward developing the Linux OS's kernel. As the Linux Foundation's announcement pointed out, it represents quite a change from the time when Microsoft CEO Steve Ballmer called Linux "a cancer" is now working within the collaborative development model to support its virtualization efforts and its customers. Because Linux has reached a state of ubiquity, in which both the enterprise and mobile computing markets are relying on the operating system, Microsoft is clearly working to adapt. In other words, some might recall the old adage: "If you can't beat 'em, join 'em.". The foundation suggested that Microsoft is "clearly working to adapt" in a world where Linux is used across enterprise and mobile environments.
The foundation's latest report, "Linux Kernel Development: How Fast It is Going, Who is Doing It, What They are Doing and Who is Sponsoring It," covers work completed through the Linux kernel 3.2 release, with an emphasis on the releases made since the last update to this report in December 2010 (2.6.36 to 3.2). 

Since 2005, there have been more than 7,800 developers contributing to the Linux kernel, according to the announcement. The foundation also claimed that "75 percent" of Linux kernel developers get paid for doing it. The full report, "Linux Kernel Development: How Fast It is Going.

Washington D.C. Online Voting System Hacked in Less Than 48 hrs

Posted by Avik Sarkar On 3/16/2012 07:33:00 pm

Washington D.C. Online Voting System Hacked By Researchers Of Michigan University in Less Than 48 hrs
The security functions of a pilot project for online voting in Washington D.C. compromised. Researchers at the University of Michigan have reported that it took them only a short time to crack the security of the whole function. "Within 48 hours of the system going live, we had gained near complete control of the election server", the researchers wrote in a paper that has now been released. "We successfully changed every vote and revealed almost every secret ballot." - Said the researchers.
The hack was only discovered after about two business days – and most likely only because the intruders left a visible trail on purpose. In 2010, the developers of the municipal e-voting system that enables voters living abroad to vote via a web site, invited security experts to conduct tests. The university researchers say that the project was developed in cooperation with the Open Source Digital Voting Foundation (OSDV) and that other US states have also worked on services similar to Washington's "Digital Vote-by-Mail Service". They also praise the system's transparency as exemplary but point out that its architecture has fundamental security weaknesses and was not able to withstand a shell injection and other common hacker techniques. The security experts investigated common vulnerable points such as login fields, the virtual ballots' content and filenames, and session cookies – and found several exploitable weaknesses. Even the Linux kernel used in the project proved to have a well known vulnerability.

Graphics Firm NVIDIA Joins The Linux Foundation

The Linux Foundation has announced that amongst its latest addition of new members is graphics firm, NVIDIA, a move which is expected to strengthen the company's relationship within the Linux community. It has been hoped that from this membership, NVIDIA may partake in open-source driver projects, as currently NVIDIA only offers closed-source drivers for Linux, which typically adds complexity to integration and prevents the open-source community from efficiently contributing enhancements and bug-fixes.
On the other-hand, at the most basic level, NVIDIA may simply wish to reap the benefits of membership to support its increasing involvement in Linux-based operating systems such as Google Android, with the firm no doubt interested in the multimedia direction that Ubuntu appears to be heading in. In a brief statement, Nvidia said that its membership in the Linux Foundation will enable it to collaborate better with "the organizations and individuals instrumental in shaping the future of Linux, enabling a great experience for users and developers of Linux."

Fedora Project Forces Users to Change Password & ssh Key

Posted by Avik Sarkar On 10/14/2011 06:29:00 pm


The Fedora Project has posted an announcement advising current users of the Fedora Account System to change their password and SSH public key before 30 November or risk their accounts being marked as inactive. The information was posted to the Fedora "announce" mailing list by Infrastructure Lead Kevin Fenzi, who stated that the change was "due to the large number of high profile sites with security breaches in recent months". Recently reported breaches include those of WineHQ, The Linux Foundation and kernel.org. The new move is precautionary, and is not due to any "specific compromise or vulnerability in Fedora Infrastructure".
The request sets out the requirement for passwords of at least 9 characters in length (20 if only lowercase characters are used) and notes that a new SSH public key must also be generated to avoid an account being marked as inactive. The announcement also includes a "Do's and Don'ts" section with several tips for increasing personal security. Instructions for changing Fedora Account System passwords and SSH public keys can be found in the Q&A section of the announcement.
According to Fedora:-
"All existing users of the Fedora Account System (FAS) at https://admin.fedoraproject.org/accounts are required to change their password and upload a NEW ssh public key before 2011-11-30. Failure to do so may result in your account being marked inactive. Passwords changed and NEW ssh public keys uploaded after 2011-10-10 will meet this requirement.

Backgound and Reasoning:-
This change event has NOT been triggered by any specific compromise or  vulnerability in Fedora Infrastructure. Rather, we believe, due to the large number of high profile sites with security breaches in recent months, that this is a great time for all Fedora contributors and users to review their security settings and move to "best practices" on their machines. Additionally, we are putting in place new rules for passwords to make them harder to guess.

New Password Rules:-
  • Nine or more characters with lower and upper case letters, digits and punctuation marks.
  • Ten or more characters with lower and upper case letters and digits.
  • Twelve or more characters with lower case letters and digits
  • Twenty or more characters with all lower case letters.
  • No maximum length.
Some Do's and Don'ts:-
  • NEVER store your ssh private key on a shared or public system.
  • ALWAYS use a strong passphrase on your ssh key.
  • If you must store passwords, use an application specifically for this purpose like revelation, gnome-keyring, seahorse, or keepassx.
  • Regularly apply your operating system's security related updates.
  • Only use ssh agent forwarding when needed ( .ssh/config: "ForwardAgent no")
  • DO verify ssh host keys via dnssec protected dns. ( .ssh/config:"VerifyHostKeyDNS yes")
  • DO consider a seperate ssh key for Fedora Infrastructure.
  • Work with and use security features like SELinux and iptables.
  • Review the Community Standard Infrastructure security document

First Ever Automotive Linux Summit (ALS 2011, Japan on November 28, 2011) By The Linux Foundation

Posted by Avik Sarkar On 10/12/2011 05:45:00 pm


The Linux Foundation announced today the first ever Automotive Linux Summit. Taking place in Japan on November 28, 2011, it will be an opportunity to address the growing need for carmakers and Linux developers to collaborate on the future of cars as devices. Nissan and Toyota will both be there, along with Intel, NEC, and a host of other mobile solutions developers.
Dig it: “cars as devices”. The Internet of Things will be upon us sooner than we imagined. Automobiles are becoming increasingly complicated, with computers and computer systems getting more and more integrated into the whole of the vehicle, not to mention connectivity being expected by the driver at the dashboard. No single vendor can provide the breadth of experience required to develop and maintain the kind of software necessary to power all the computing on a car, so the vendor-neutral approach of the Linux stack makes tremendous sense to car makers.
According to Linux Foundation:-
"Automotive Linux Summit (ALS) is event specifically for the automotive industry and the growing cross-industry ecosystem for future mobility solutions.
The Automotive Linux Summit is the premier vendor-neutral business and technical conference for companies and developers using or looking to use Linux and open-source technologies in automotive applications ranging from in-vehicle on-board system to cloud solutions for vehicle-to-vehicle and vehicle-to-infrastructure communications.
ALS is the event where automotive expertise meets open-source excellence talking and collaborating on solutions meeting the challenges of tomorrow's vehicular applications, traffic and mobility management solutions. For those who are developing embedded and/or infrastructure systems for the automotive industry and looking how they can leverage the power and flexibility of Linux and open-source to jump-start their product development ALS will be the one-stop source for business-oriented, technical and legal information.
Ultimately, ALS will bring together the key players and industry excellence to create a momentum for new opportunities through open innovation."

Embedded Linux Conference Europe (ELCE)

Posted by Avik Sarkar On 10/09/2011 07:35:00 pm

The Linux Foundation and CE Linux Forum announced a schedule for the Embedded Linux Conference Europe (ELCE), set to take place Oct. 26-28 in Prague. Co-located with LinuxCon Europe, ELCE 2011 offers 50 presentations on Linux and Android -- including projects such as Genivi, Yocto, Linaro, and possibly Tizen -- plus speakers ranging from Linus Torvalds to Intel's Dirk Hohndel.
This year's Embedded Linux Conference Europe conference is the second ELCE event since the CE Linux Forum (CELF) forum merged into the Linux Foundation (LF) as a working group in Oct. 2010. (The first post-LF event occurred the same week the merger was announced last October in Cambridge, U.K.)  CELF also sponsors the U.S. ELC show, which this year was held in April in San Francisco. Merging with the LF brings some benefits to CELF's conference attendees, in that ELC/ELCE registrations also provide free passes to co-located LF conferences. In Prague, for example, ELCE attendees can also attend the world debut of LinuxCon Europe, which will be held at the same venue during the same three-day Oct. 26-28 period. A GStreamer conference is also co-located with the events.
ELCE will start off Oct. 26 with an address from LF Executive Director Jim Zemlin, who will "imagine a world without Linux." This will be followed by a Kernel Developer Panel that features a star-studded cast including Linux creator Linus Torvalds (pictured at right), real-time Linux pioneer Thomas Gleixner, Intel's Alan Cox, and IBM's Paul McKenney. The Oct. 27 keynotes, meanwhile, include Ixonos President of Global Solutions Antti Aumo discussing the "Cloud Phone," which may or may not refer to his company's announced support for the HTML5-focused Tizen spin-off of MeeGo and LiMo. Aumo's address will be followed by Intel Chief Linux and Open Source Technologist Dirk Hondel (pictured at left) offering a "Reflection on 20 years of Linux." Perhaps Dirk, too, can help the somewhat skeptical Linux community understand how Tizen will do any better than MeeGo and LiMo.

Further information:-
The Embedded Linux Conference Europe (ELCE) will be held October 26-28, Clarion Congress Hotel, in Prague, Czech Republic. Combined registration for ELCE and the collocated LinuxCon Europe, costs $550, with discounts available for students and "hobbyists."

Registration specifics may be found on this ELCE Europe registration page.
More general information and session details may be found on the ELCE Europe site.

Security Breach on The Linux Foundation, Linux.com & their Subdomains

Posted by Avik Sarkar On 9/12/2011 04:59:00 pm


Dig a the history and go back into the previous week I hope you can surely remember  the attack on Linuxkernel.org. Now The Linux foundation is under cyber attack. the Linux Foundation has pulled its websites from the web to clean up from a “security breach.”
A notice posted on the Linux Foundation said the entire infrastructure including LinuxFoundation.org, Linux.com, and their sub domains are down for maintenance due to a security breach that was discovered on September 8, 2011.
“The LinuxFoundation made this decision in the interest of extreme caution and security best practices. We believe this breach was connected to the intrusion on kernel.org,” the group said.


Official Notice By The Linux Foundation is posted on their website and that is:- 

"Linux Foundation infrastructure including LinuxFoundation.org, Linux.com, and their subdomains are down for maintenance due to a security breach that was discovered on September 8, 2011. The Linux Foundation made this decision in the interest of extreme caution and security best practices. We believe this breach was connected to the intrusion on kernel.org.
We are in the process of restoring services in a secure manner as quickly as possible. As with any intrusion and as a matter of caution, you should consider the passwords and SSH keys that you have used on these sites compromised. If you have reused these passwords on other sites, please change them immediately. We are currently auditing all systems and will update this statement when we have more information.
We apologize for the inconvenience. We are taking this matter seriously and appreciate your patience. The Linux Foundation infrastructure houses a variety of services and programs including Linux.com, Open Printing, Linux Mark, Linux Foundation events and others, but does not include the Linux kernel or its code repositories.
Please contact us at info@linuxfoundation.org with questions about this matter."

Apache 2.2.20 Released (DDoS Vulnerability Fixed)

Posted by Avik Sarkar On 9/01/2011 03:37:00 pm


This afternoon the Apache Foundation released an awaited fix to the denial of service (DoS) vulnerability reported a few days ago. The fixes in version 2.2.20 of the Apache httpd server reduce the amount of memory that is used by range requests. If the total bytes of a file requested exceed the total file size, httpd will return the entire file. This follows closely on the heels of a tool released to the Full Disclosure mailing list this week that exploits the flaw. Apache web administrators are encouraged to apply this fix immediately. Unfortunately, as we see all too frequently, many Linux and Unix administrators "set and forget" their installations and never bother to look after their servers.
The Apache team should be applauded for testing and releasing an important security fix so quickly. Now it is up to you, the IT administrators who are using Apache, to follow through and apply these fixes.

Microsoft & SuSe Alliance (MS is Purchasing $100 Million of Support from SuSe)

Posted by Avik Sarkar On 7/28/2011 02:51:00 am


Despite the problematic relationship between Microsoft and Linux vendors over the years, it’s not always been a case of frosty relationships.  Previously Microsoft decided to work closely with Novell on the Enterprise version of SUSE Linux, and now the company has renewed their alliance with SUSE by purchasing $100 million of support.
This support will be for Windows enterprise customers who are also running a SUSE machines in conjunction with their Windows boxes.  It’s a good move on the part of Microsoft to avoid upsetting business customers who are already feeling squeezed with extremely tight profit margins and software assurance costs to the Redmond giant.  The move will mean these enterprise customers won’t have to pay for further Linux support.

In a press release Microsoft said… 
”As IT operating environments become increasingly consumerized, cloud-based and automated, there is an implicit expectation that the underlying technologies from multiple vendors should work together. For this reason, the collaborative relationship between Microsoft and SUSE has come to be viewed as a model for the industry.  The joint Microsoft-SUSE collaboration has served more than 725 customers worldwide across a range of industries, such as manufacturing, oil and gas, healthcare, and financial services.”

“Our collaboration with SUSE not only helps customers to achieve success today, but also seeks to provide them with a solid foundation for tomorrow,” said Sandy Gupta, general manager of the Open Solutions Group at Microsoft. “Through our continued engagement on the technical side, an outstanding support offering from SUSE and our ability to provide mutual IP assurance, we feel confident that we will be able to deliver core value to those running mixed-source IT environments well into the future – and into the cloud.”

This move doesn’t mean that Microsoft will stop complaining about Linux or even stop suing for patent infringement, as these are just what the technology industry does (probably at the request of lawyers needing to justify their sky-high salaries).  It’s further evidence though that, deep down, technology companies around the world are more interested in building better experiences for their customers than they are feathering their own nests.

This is something I have always felt sets the tech world apart from other industries such as finance or energy.  It’s a good move and both Microsoft and Novell should be applauded for working together again.
