Malicious backdoor in open-source messaging apps not spotted for 3 months
For almost three months, versions of three widely distributed open-source applications from Horde.org contained a backdoor that allowed attackers to remotely execute malicious PHP code on systems that ran the programs.

This is interesting…
“The impact through Linux distribution should be not so important,” Wednesday’s post went on to say. “Only users who have download the source code from FTP are mainly affected.”
Horde’s advisory said the releases were altered after unidentified hackers breached an FTP server used to distribute the installation packages.
New research: There’s no need to panic over factorable keys–just mind your Ps and Qs
We have been able to remotely compromise about 0.4% of all the public keys used for SSL web site security. The keys we were able to compromise were generated incorrectly–using predictable “random” numbers that were sometimes repeated. There were two kinds of problems: keys that were generated with predictable randomness, and a subset of these, where the lack of randomness allows a remote attacker to efficiently factor the public key and obtain the private key. With the private key, an attacker can impersonate a web site or possibly decrypt encrypted traffic to that web site. We’ve developed a tool that can factor these keys and give us the private keys to all the hosts vulnerable to this attack on the Internet in only a few hours.
The last time I was at this blog was many years ago when he showed how to hack electronic voting machines.
Hadoop Tutorial
Welcome to the Yahoo! Hadoop tutorial! This series of tutorial documents will walk you through many aspects of the Apache Hadoop system. You will be shown how to set up simple and advanced cluster configurations, use the distributed file system, and develop complex Hadoop MapReduce applications. Other related systems are also reviewed.
CentOS 5 – BIND/named network unreachable resolving issue
Disable the IPV6 in BIND. For CentOS 5.4, edit the /etc/sysconfig/named file and add the following options into the BIND startup
OPTIONS=”-4″
This will cause the BIND server to only resolve or use IPV4 and disable IPV6 support. Save the file and restart BIND server.

This has been going on for months and I finally noticed these errors from named filling up syslog. The above fix worked and now syslog is quiet again — the way it should be.
NASA unplugs last mainframe
Of course NASA is just one of the latest high profile mainframe decommissionings. In 2009 The U.S. House of Representatives took its last mainframe offline. At the time Network World wrote: “The last mainframe supposedly enjoyed “quasi-celebrity status” within the House data center, having spent 12 years keeping the House’s inventory control records and financial management data, among other tasks. But it was time for a change, with the House spending $30,000 a year to power the mainframe and another $700,000 each year for maintenance and support.”

Cue violins.
RADIUS
Remote Authentication Dial In User Service (RADIUS) is a networking protocol that provides centralized Authentication, Authorization, and Accounting (AAA) management for computers to connect and use a network service. RADIUS was developed by Livingston Enterprises, Inc., in 1991 as an access server authentication and accounting protocol and later brought into the Internet Engineering Task Force (IETF) standards.[1]
NZXT Switch 810: When Too Much Isn’t Enough
I think there’s ultimately a market for the Switch 810 for users that can take advantage of all of its customizability, as well as users who want to employ a tremendous amount of custom watercooling. For them it’s going to be worth checking out. If you don’t need to install a 360mm radiator, though, Rosewill’s Thor v2 remains the superior buy. It performs better, costs less, and is quieter to boot. NZXT’s case is a good one, but not great, and definitely not competitive at $169.

It seems like the market are calling cases enclosures. I like the term enclosures better. It sounds more sophisticated. 🙂
The Opteron 6276: a closer look
First let’s look at the pricing. The Opteron 6276 is priced similar to an E5649, which is clocked 5% lower than the X5650 we tested. If you calculate the price of a Dell R710 with the Xeon E5649 and compare it with a Dell R715 with the Opteron 6276 with similar specs, you end up more or less the same acquisition cost. However, the E5649 is an 80W TDP and should thus consume a bit less power. That is why we argued that the Opteron 6276 should at least offer a price/performance bonus and perform like an X5650. The X5650 is roughly $220 more expensive, so you end up with the dual socket Xeon system costing about $440 more. On a fully speced server, that is about a 10% price difference.
