Integrating RHV & OpenStack with Neutron

Hi folks, I recently posted an article on one of the official Red Hat blogs about the new Neutron integration between RHV and RHOSP. I have to say it’s very cool and might change the way you look at networking capabilities in RHV, at least if you’re also using RHOSP in the same data center.

As a side note, I’ve mentioned my friend and colleague, Tony James in recent posts and he makes another appearance this week. He helped pull together the configuration steps as well as the demo that we recorded. Big kudos to to “Big T”.

Back to the actual integration. If you don’t want to look at the other article, the condensed version of “why should you might care” is as follows:

  1. Run applications across RHV & RHOSP – front end of the app on RHOSP and the back end on RHV using the Neutron integration to bridge the network gap.
  2. Add SDN capabilities to RHV via the Neutron integration, even if the app only exists in RHV.
  3. Manage the SDN network topologies for both RHV and RHOSP from a single management space (web or programmatic).

Those are the 3 big use cases, in a nutshell. If Continue reading

Impending cumulative updates unnerve Windows patch experts

Microsoft's decision to force Windows 10's patch and maintenance model on customers running the older-but-more-popular Windows 7 has patch experts nervous."Bottom line, everyone is holding their breath, hoping for the best, expecting the worst," said Susan Bradley in an email. Bradley is well known in Windows circles for her expertise on Microsoft's patching processes: She writes on the topic for the Windows Secrets newsletter and moderates the PatchMangement.org mailing list, where business IT administrators discuss update tradecraft.Bradley's anxiety stems from Microsoft's announcement last month that beginning in October it will offer only cumulative security updates for Windows 7 and 8.1, ending the decades-old practice of letting customers choose which patches they apply.To read this article in full or to leave a comment, please click here

6 expert tips to better secure third-party network access

Third-party accessImage by Harris & Ewing Collection (Library of Congress)Earlier this year, the Soha Third-Party Advisory Group conducted a study that surveyed more than 200 enterprise IT and security C-Level executives, directors and managers about the daily challenges they face providing fast and secure third-party application access to their contractors and suppliers. The survey revealed that 98 percent of respondents do not consider third-party access a top priority in terms of IT initiatives and budget allocation. This is a huge concern, considering that third parties cause or are implicated in 63 percent of all data breaches.To read this article in full or to leave a comment, please click here

5 tech trends that have Turing Award winners worried

Technology has considerable potential to make the world better, but those benefits are far from guaranteed. Plenty of downsides can pop up along the way, and some of them have Turing Award winners especially worried.1. The internet echo chamber "Technology by itself is not evil, but people can use it for bad things," Barbara Liskov, an Institute Professor at MIT, told an audience of journalists Thursday at the Heidelberg Laureate Forum in Germany. "I do worry a lot about what's going on."The ability to selectively filter out news and opinions that don't agree with one's own viewpoint is one of Liskov's top concerns.To read this article in full or to leave a comment, please click here

Saving Backup/Rescue Config on Juniper

A lot of times I find myself having to back a config up on a Juniper before I start work. Usually, I want a quick point I can restore to if I need to rollback. So enter rescue configurations to the, errr, rescue?

request system configuration rescue save

This saves the current saved system configuration as a rescue configuration you can easily rollback to with.

#rollback rescue
#commit

You can also save the current configuration to file using:
>file copy /config/juniper.conf.gz /var/tmp/temp_backup.cfg

/config/juniper.conf.gz is synonymous with the current running configuration.

Potentially, you could stash files in /var/tmp/ and restore them using the above. And restore using your backup with #load replace /var/tmp/temp_backup.cfg

View your stashed files using file list /var/tmp


Vint Cerf’s dream do-over: 2 ways he’d make the internet different

Vint Cerf is considered a father of the internet, but that doesn't mean there aren't things he would do differently if given a fresh chance to create it all over again."If I could have justified it, putting in a 128-bit address space would have been nice so we wouldn't have to go through this painful, 20-year process of going from IPv4 to IPv6," Cerf told an audience of journalists Thursday during a press conference at the Heidelberg Laureate Forum in Germany.IPv4, the first publicly used version of the Internet Protocol, included an addressing system that used 32-bit numerical identifiers. It soon became apparent that it would lead to an exhaustion of addresses, however, spurring the creation of IPv6 as a replacement. Roughly a year ago, North America officially ran out of new addresses based on IPv4.  To read this article in full or to leave a comment, please click here

Majority of US users opt to stay with Galaxy Note7 after recall

Samsung Electronics may have some comfort after its debacle with faulty batteries in the Galaxy Note7 smartphone.The South Korean company reported Thursday that about 500,000 devices, or half of the recalled Galaxy Note7 phones sold in the U.S., have been exchanged through its program.Interestingly, "90 percent of Galaxy Note7 owners have been opting to receive the new Galaxy Note7," since the phones became available on Wednesday, Samsung said. That figure suggests that most of the users of the Note7 have chosen to stay with the smartphone model, with new batteries, rather than go in for a refund or exchange the phone with another Samsung model.To read this article in full or to leave a comment, please click here

Pushing Database Scalability Up And Out With GPUs

What is good for the simulation and the machine learning is, as it turns out, also good for the database. The performance and thermal limits of traditional CPUs have made GPUs the go-to accelerator for these workloads at extreme scale, and now databases, which are thread monsters in their own right, are also turning to GPUs to get a performance and scale boost.

Commercializing GPU databases takes time, and Kinetica, formerly known as GPUdb, is making a bit of a splash ahead of the Strata+Hadoop World conference next week as it brags about the performance and scale of the parallel …

Hackers have a treasure trove of data with the Yahoo breach

The massive breach at Yahoo means that a treasure trove of stolen data is in the hands of hackers -- putting millions of internet users at risk.At least half a billion Yahoo accounts have been affected in one of the biggest data breaches in history.

Apple Car rumors resurface amid new buyout rumors

One of the more fascinating rumors surrounding Apple these days rests on whether or not the company will ever roll out an Apple branded electric car. Undoubtedly, Apple has been spending lots of R&D resources on its electric car initiative, but whether or not that research will actually result in a car remains to be seen.That said, there were some interesting rumors in the news this week. First and foremost, a report surfaced indicating that Apple was potentially interested in acquiring McLaren, a company that most people know as a purveyor of expensive sports cars and incredibly fast Formula 1 race cars. That rumor naturally got the Apple blogosphere going but it wasn’t long before a McLaren spokesperson came forward and denied the report.To read this article in full or to leave a comment, please click here
