Cumulus Linux Switch Monitoring with Datadog

As a Linux platform, one of the cool things is that we often don’t have visibility into how customers use their switches running Cumulus Linux. They buy HCL-compatible hardware from our partners, and with some training and enablement, are off to the races.

The idea for running Datadog in Cumulus Linux came about for the simple reason that we were in adjacent booths at PuppetConf last year, and we all figured it would be cool to try it out. Further, since Datadog already provides visibility across systems, apps and services, they were interested in seeing how networking can be added into the mix. As you will see, it turns out to be pretty simple.

Installing Datadog in Cumulus Linux

The Datadog agent, as with most things Debian, installs easily on Cumulus Linux. For x86 switches, this is as simple as installing a Debian package and performing simple changes in the Datadog agent files, such as the application/API key, which is the tag associated with the switch. You can easily automate this installation using common automation tools like Puppet and Ansible.

Configuration

Since the Datadog agent is designed for servers, metrics can be collected using Datadog’s SNMP plugin, a custom sFlow Continue reading

Three Tips for Technical Blogging

From time to time, I’m asked by new or potential technical bloggers for advice on how to get into writing, or how to overcome some kind of mental reservation that he/she may have.

It’s actually somewhat ironic – I still suffer from many of the same issues that I suffered from back before Keeping It Classless existed.

I have been having some serious "Newbie Blogger" issues last few weeks. Ironically, I feel compelled to write about them.

So, truth be told, I constantly remind myself of the same advice that I give to the bloggers-to-be that ask me for advice. It’s high time that I open the kimono a little bit and hopefully help someone in the process. Here are my top five tips for technical bloggers – whether you’re just getting started, or if you’re already fairly established but maybe hitting some blockage.

Know Why You Do It

Be keenly aware of the motivation(s) that drive your blogging. Write them down. Look at them every day. Keeping these in mind should be your primary source of energy when writing about a technical topic. Unless blogging is your actual job (in which case Continue reading

Lebanese cyberespionage campaign hits defense, telecom, media firms worldwide

For the past two years, a cyberespionage group that likely operates from Lebanon has hacked into hundreds of defense contractors, telecommunications operators, media groups and educational organizations from at least 10 countries.The still-active attack campaign was uncovered and analyzed recently by security researchers from Check Point Software Technologies, who dubbed it Volatile Cedar. The company’s researchers found evidence that the attackers started their operation in late 2012, but have managed to fly under the radar until now by carefully adapting their tools to avoid being detected by antivirus programs.Unlike most cyberespionage groups, the Volatile Cedar attackers do not use spear phishing or drive-by downloads to gain a foothold into their victims’ networks. Instead they target Web servers and use them as initial entry points.To read this article in full or to leave a comment, please click here

Broken NFC terminals, lack of retail support stifling Apple Pay usage

Apple Pay got off to a hot start after its debut in October, attracting 11% of all credit card-using households and converting 66% of iPhone 6 users in its first four months on the market, according to an ongoing study of more than 3,000 credit card users conducted by market research firm Phoenix Marketing International.Although iPhone users appeared eager to try out Apple's new mobile payment plan – the study estimates that more than 88% of those who set up an Apple Pay wallet went on to make a purchase with it either in a retail store or in a mobile app – they have run short on opportunities to use them in the time since."The demand is there: 59% of Apple Pay users have gone into a store and asked to make a purchase with Apple Pay," Greg Weed, Phoenix Marketing International director of research, said in a statement. "But so is the disappointment: 47% visited a store that was listed as an Apple Pay merchant only to find out that the specific store they visited did not accept (or were not ready to accept) Apple Pay."To read this article in full or to leave Continue reading

The Upload: Your tech news briefing for Tuesday, March 31

Silk Road investigators charged with stealing bitcoinVirtual evidence is no less tempting to a corrupt agent than cash or drugs found in a raid: Two former US federal agents face charges related to stealing hundreds of thousands of dollars worth of bitcoin in the course of investigating the Silk Road marketplace. A former DEA special agent, who worked undercover to cultivate a relationship with recently convicted Ross Ulbricht, allegedly used online personas to engage in complex bitcoin transactions to steal both from the government and the targets of the investigation. And a former Secret Service agent who served as a computer forensics expert allegedly took more than $800,000 in digital currency that he gained control of during the Silk Road investigation—and put it in his account at now-defunct bitcoin exchange Mt Gox.To read this article in full or to leave a comment, please click here

LG may introduce leather-covered flagship smartphone at April 28 event

LG Electronics is expected to introduce its next high-end smartphone on April 28, and has hinted that the back of the device will be covered in leather.In the light of the growing focus on looks at the recent Mobile World Congress, it wouldn’t be surprising if LG uses better materials for the successor to the G3, which is expected to be called the G4. The invite for April 28 that the company sent out on Tuesday just said “save the date” and “see the Great”, but the text is written over a leather back with stitching on one side.LG wouldn’t be the first to offer leather or faux leather as an alternative. Real leather is an option on Motorola Mobility’s Moto Maker customization service, and Samsung Electronics uses faux leather on the back of the Galaxy Note 4.To read this article in full or to leave a comment, please click here

Thought for The Day: NetBIOS over IPX

I found a capture file from 2002. I must have been troubleshooting name resolution of NetBIOS over IPX for print servers because I am only capturing broadcasts on the Ethernet segment. And Wireshark can still open a data format from 15 years ago and render the data.   I surely do not miss these days. […]
