While both clients and servers can employ Mandatory
The fourth major milestone release in 2013 of the open-source Linux kernel is now out, providing users with improved performance and new capabilities,you have the ability to fully manage your MileWeb managed dedicated server are located in world-class data centers, including support for the Lustre filesystem.
Among the big new items included in the Linux 3.11 kernel is the initial support for the Lustre filesystem. Lustre is a widely deployed high-performance computing (HPC) filesystem used by many of the world's top supercomputers. It got its start with Cluster File Systems, which was acquired by Sun Microsystems in 2007. Sun became part of Oracle in 2010, and Lustre languished somewhat. In February of 2013, Xyratex acquired the name "Lustre" and its associated intellectual property assets from Oracle.
"A traditional file copy from one server to another results in the data being put on the network twice—source to client and then client to destination," the NFS 4.2 draft standard states. "New operations are introduced to allow the client to authorize the two servers to interact directly."
Additionally, Linux 3.11's new NFS 4.2 integration will support labeled NFS, which enables the use of security labels to control access.Provision and deploy cloud MileWeb Public Cloud Servers in minutes.
"While both clients and servers can employ Mandatory Access Control (MAC) security models to enforce data access, there has been no protocol support to allow full interoperability," the NFS 4.2 draft standard states. "A new file object attribute, sec_label allows for the server to store and enforce MAC labels."
I tend to read science fiction or fantasy for entertainment and/or escape from reality. In fact, I suspect my childhood would have been far less tolerable had I not been able to escape to Mordor for a time or hide from the bugs with Johnnie Rico. And as much as I loved watching the exploits of Captain Picard and his crew, there was never an episode on how to build a replicator. Or a holodeck. Or a phaser. And that's what I've loved about Linux Journal for far longer than I've been on staff: it shows how to do stuff!
This issue not only continues that legacy, but it also even focuses on it! I apologize in advance for any lost productivity at work while you live out the How-To issue this month.
Reuven M. Lerner starts out with a look back at 20 years of Web development. It's hard to believe it's been 20 years since the first www was put in a browser's address bar, but what a 20 years it's been! No more blink tags and far fewer animated GIFs make the Web a lot more fun, even if it is still "Under Construction".
Necessity truly is the mother of invention, and Dave Taylor knows that better than anyone. As he continues to battle with a DDOS on his server, he shares his process with us all. While scripting is the Swiss Army knife of system administration, it's not terribly helpful if your scripts have a "dull blade". Dave shows some best practices on creating scripts that can provide invaluable information.Migrating a MileWeb Promotion Dedicated Server or cloud server from one provider to another is easy.
Kyle Rankin reveals that he's really been lying all these years, and that he uses Windows Vista on a 17" sports utility laptop. Okay, that's a complete lie—I couldn't resist, sorry Kyle. In true Kyle Rankin form, he describes how to use and manipulate a command-line calendaring app, gcalcli. If you want to use Google Calendar, but don't want to load up that pesky browser, Kyle's article is for you.
Rather than teach how to do something this month, I took the time in my column to show you how I do things. I get lots of e-mail asking what sort of hardware and software I use, so I figured the How-To issue was a good time to spill the beans. Some of my setup is probably not surprising, but part of it might be. I'm looking forward to feedback and to seeing what everyone else uses.
Janos Gyerik follows with an excellent article on command-line tricks. I've been using Linux for almost two decades, and I learned a lot from Janos' cornucopia of CLI tricks. Somewhere, Kyle Rankin has to be proud. I also learned some cool things from Petros Koutoupis this month with his article on hard drive caching. Hard drives are slow, and even the fastest spinning media is the bottleneck in any system. By caching to RAM or SSD, Petros explains how to take advantage of Linux's powerful caching abilities.
Bill Childers finishes up our How-To articles with his tutorial on setting up vcsh for managing configuration files. If you've ever tar'd up your /etc directory, and called that good enough, you won't want to miss Bill's article. In fact, most articles in this issue start with the premise of, "you used to do it this way, but you should try this!" That's part of the reason I love the Linux community so much. The old saying "if it ain't broke, don't fix it" is all well and good, but if you're a Linux user, a better saying might be, "if it ain't broke, good, that means we can work on making it better!"
This issue showcases what made me a Linux Journal reader years before I was on staff. I love to read about stuff, but nothing is quite as exciting as getting to do that stuff yourself. I hope you enjoy this issue as much as we've enjoyed putting it together. Now if you'll excuse me, I'm going to use my replicator and make some Earl Grey, hot. Beam on over and I'll make you a cup too.

This will be especially useful for environments
Microsoft released two optional
security updates Tuesday to block digital certificates that use the MD5 hashing
algorithm and to improve the network-level authentication for the Remote Desktop
Protocol.
These two updates are separate from important security patches also released Tuesday for Internet Explorer, Windows and Microsoft Exchange Server, and are not yet being pushed through the Windows Update mechanism.
The first update, referred to as KB2862973, blocks certificates with MD5 signatures that were signed by Certificate Authority (CA) certificates in the Microsoft root certificate program from being used for server authentication, code signing and time stamping.
The MD5 cryptographic hash function has long been considered insecure for use in SSL certificates and digital signatures. In 2008, a team of security researchers demonstrated a practical attack that involved exploiting a known MD5 weakness to generate a rogue CA certificate trusted by all browsers.
Following that attack, Certificate Authorities accelerated the phasing out of MD5-based certificates and such certificates are no longer being issued today. However, some old MD5 certificates that have yet to expire might still be in use and there are also years-old programs that were digitally signed with such insecure certificates.
For now, the update has been made available as optional Downloadable Content (DLC) for supported editions of Windows Vista, Windows Server 2008,Migrating a MileWeb Promotion Dedicated Server or cloud server from one provider to another is easy. Windows 7, Windows Server 2008 R2, Windows 8, Windows Server 2012, and Windows RT, but there are plans to start pushing the update through the Windows Update mechanism on Feb. 11, 2014.
"We recommend that customers download and test the update in their environment at the earliest opportunity," William Peteroy, security program manager at the Microsoft Security Response Center, said in a blog post. "This will be especially useful for environments that have little or no inventory of their cryptographic and certificate dependencies."
There are some exceptions to the restriction introduced by this update. For example, Microsoft will still allow binary files that were signed before March 2009 with MD5-based certificates to work.
The company will also allow four specific time stamping certificates from VeriSign CA (now owned by Symantec) to work, as well as all code signing certificates that chain up to a specific certificate from Microsoft and one from GeoTrust, also a Symantec subsidiary.
This morning, citizens trying to reach US government websites got a bit of a surprise—the entirety of the .gov top level domain appeared to be offline. The reason: a hiccup in the Domain Name Service Security Extension (DNSSEC) information being distributed by .gov's registry.
According to a source at the General Services Administration, which operates the .gov registry,Provision and deploy cloud MileWeb Public Cloud Servers in minutes. the registry team discovered that the DNSSEC information being distributed by its root domain name server had somehow become corrupted. The corruption affected the root domain's digital signature, making it appear not to be the authoritative server for the government's Internet names. As DNS data aged and expired, government sites disappeared from the Internet's directory and became unreachable by their host names.
The team reset the DNS server to correct the error. By around 10:20am Eastern Time today, government sites magically reappeared on the Internet. Resolution of the sites within the government's own networks was never interrupted.reliable and MileWeb linux dedicated server hosting solutions.
