If management interface of VIRL routers are accessible from outside machines, we can run management application in the client machine and connect directly … Continue reading Connecting VIRL, CML networks to outside world →

US gains in mobile patents as IBM passes Samsung

The U.S. widened its lead in mobile patents last year and IBM took the top spot in new patents granted in that space, according to a report this week that analyzed data from both the U.S. and Europe.While the number of mobile patents granted by the U.S. Patent and Trademark Office (USPTO) jumped by 17 percent between 2013 and 2014, the total fell by 4 percent at the European Patent Office (EPO), according to Chetan Sharma Consulting. The U.S. continued to gain on Europe as the place where mobile inventions are devised, a trend driven by software development in Silicon Valley and Americans’ heavy use of mobile data, the report said.To read this article in full or to leave a comment, please click here

The .onion address

A draft RFC for Tor's .onion address is finally being written. This is a proper thing. Like the old days of the Internet, people just did things, then documented them later. Tor's .onion addresses have been in use for quite a while (I just setup another one yesterday). It's time that we documented this for the rest of the community, to forestall problems like somebody registering .onion as a DNS TLD.

One quibble I have with the document is section 2.1, which says:

1. Users: human users are expected to recognize .onion names as having different security properties, and also being only available through software that is aware of onion addresses.

This certain documents current usage, where Tor is a special system run separately from the rest of the Internet. However, it appears to deny a hypothetical future were Tor is more integrated.

For example, imagine a world where Chrome simply integrates Tor libraries, and that whenever anybody clicks on an .onion link, that it automatically activates the Tor software, establishes a circuit, and grabs the indicated page -- all without the user having to be aware of Tor. This could do much to increase the usability of the Continue reading

Benchmark scores show performance gap between Surface 3 and Surface Pro 3, iPad Air 2

A handful of benchmark scores for Microsoft's not-yet-released Surface 3 tablet hint that it's between a third and half as fast as the company's older 2-in-1, the more powerful Surface Pro 3.The scores also show that Apple's iPad Air -- which starts at the same $499 price of the Surface 3 -- is between 36% and 93% faster than Microsoft's latest device.Five Surface 3 benchmark scores posted on Primate Labs' Geekbench in the last two days have ranged from 949 to 1009 for single-core, and from 3200 to 3430 for multi-core.The tests may have been run by people who have a review unit; like other hardware makers, Microsoft often seeds media outlets and influential blogs with machines prior to bringing them to retail, giving reviewers hands-on time so that they can publish their takes on or before the sale or ship date.To read this article in full or to leave a comment, please click here

Senator wants bomb-making information removed from the Internet

After two U.S. women were charged this week with conspiring to build bombs in support of terrorist groups, a U.S. senator wants two publications that include bomb-making instructions deleted from the Internet.Senator Dianne Feinstein, a California Democrat, called for the 44-year-old Anarchist Cookbook and al-Qaeda’s Inspire Magazine to be banished from the Web, notwithstanding the difficulty of removing material from the entire Internet or the U.S. Constitution’s First Amendment. It’s not the first time that Feinstein has tried to ban publications that instruct would-be bomb-makers.“I am particularly struck that the alleged bombers made use of online bomb-making guides like the Anarchist Cookbook and Inspire Magazine,” Feinstein, a veteran member of the Senate Intelligence Committee, said in a statement. “These documents are not, in my view, protected by the First Amendment and should be removed from the Internet.”To read this article in full or to leave a comment, please click here

Use software license optimization tools to get your money’s worth out of SaaS

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach.

Software as a Service (SaaS) breaks the shackles of traditional software licensing approaches, but savvy users still optimize their SaaS environments to avoid undue costs.

SaaS subscription models typically require a one to three year commitment. Customers are invoiced, usually on a monthly basis, and the license typically uses some sort of billing metric based on resource usage, such as the number of end users that can access the product. The flexibility of SaaS licensing models enables organizations to expand the use of the product according to their needs during the term of the subscription.

Exporting RSA keys from Cisco ASA: Harder than it should be

Unlike Cisco IOS routers, which by default don't allow RSA private keys to be exported from NVRAM, Cisco ASAs don't protect private keys. But there's no command (of which I'm aware) to directly export the keys either.

Sometimes you need to squirrel away those keys. You can do it by getting a certificate that uses the keys, then exporting a certificate bundle (with private key included). Here's how.

First, create a key:
 crypto key generate rsa label mykey modulus 2048

Next, create a trustpoint which references the key, and generate a self-signed certificate:
 crypto ca trustpoint throwaway  
  keypair mykey  
  enrollment self  
 crypto ca enroll throwaway noconfirm

Now the throwaway trustpoint has a certificate. Export that certificate to the terminal.
 no terminal pager  
 crypto ca export throwaway pkcs12 <passphrase>

Save the blob of text including the begin/end lines. The blob is a PKCS12 bundle encrypted using the passphrase above and then base64 encoded. Be sure to save the encryption passphrase.
 -----BEGIN PKCS12-----

 -----END PKCS12-----

We no longer need the certificate or the throwaway trustpoint in which it's stored. Kill it. The private key will survive.

PlexxiPulse—Spotlight on SDN

Infonetics analyst Clifford Grossner recently released a SDN enterprise study which found that nearly 80 percent of medium and large size businesses plan to implement SDN technology in the data center by 2017. The survey of 153 businesses also revealed that 65 percent of respondents are currently conducting data center SDN lab trials or plan to do so in 2015. Marcia Savage of NetworkComputing cites the Infonetics data and names SDN as a top networking trend in a piece this week titled “What’s Hot In Networking: 7 Key Trends.” We’re excited to see SDN in the spotlight. Marcia’s piece and the Infonetics study are both worth a read before you kick off your weekend.
