Docker Networking: macvlans with VLANs

If you have read my introduction to macvlans and tried the basic macvlan bridge mode network configuration you are aware that a single Docker host network interface can serve as a parent interface to one macvlan or ipvlan network only.

One macvlan, one Layer 2 domain and one subnet per physical interface, however, is a rather serious limitation in a modern virtualization solution. Fortunately, a Docker host sub-interface can serve as a parent interface for the macvlan network. This aligns perfectly with the Linux implementation of VLANs, where each VLAN on a 802.1Q trunk connection is terminated on a sub-interface of the physical interface. You can map each Docker host interface to a macvlan network, thus extending the Layer 2 domain from the VLAN into the macvlan network.

Multiple macvlans with VLANs configuration

You have a Docker host with a single eth0 interface connected to a router. Connection between the router and the Docker host is configured as 802.1Q trunk on the router with VLAN 10 and VLAN 20.

Configure VLAN 10 and VLAN 20 on your router. Add the following IP addresses to the Layer 3 interface: 10.0.10.1/24 and 2001:db8:babe:10::1/64 for VLAN 10, 10. Continue reading

DELL OS10 – FIB Optimisation

Dell OS10 is an open network operating system ounces its open network operating system(NOS) called OS10. Here are my thoughts and reactions. Operating System OS10 is a open source linux for networking devices. The base operating system has limited features in the same way that Windows or Linux on x86 has limited features.

Juniper’s new access switches add to its cloud-focused lineup

Juniper Networks’ Unite architecture is living up to its name, bringing more enterprise network gear into its system for simplified management and scaling.The latest additions to the lineup are entry-level and midrange access switches that also include other features for ease of use.Unite, introduced last year for the EX9200 core switches and other Juniper and third-party components, is designed to help enterprises turn their own infrastructure into private clouds and link those to public clouds in a hybrid architecture. It’s built around Junos Fusion Enterprise software, which collapses multiple network layers into one for simpler management. That gives administrators a single point of management.To read this article in full or to leave a comment, please click here

Up to a dozen banks are reportedly investigating potential SWIFT breaches

More banks have reportedly launched investigations into potential security breaches on their networks after hackers stole US$81 million from the Bangladesh central bank earlier this year through rogue SWIFT transfers.Security firm FireEye, which was hired to investigate the Bangladesh bank attack, was also called in to look for possible compromises at up to 12 additional banks, Bloomberg reported Thursday, citing an unnamed source familiar with the investigations.Most of the banks are from Southeast Asia but include banks in the Philippines and New Zealand, Bloomberg reported.To read this article in full or to leave a comment, please click here

Worth Reading: Are NVMe fabrics in your future?

NVMeF promises both a huge gain in system performance and new ways to configure systems. To understand what this means, we have to separate NVMe from its current implementation that uses direct PCIe connects. The PCIe approach arose a few years back from the then top-tier persistent storage, the flash card, which had reached the limit of SCSI-based operations due to IO stack overhead and interrupt handling problems. —Network Computing

Euro agencies on encryption backdoors: Create ‘decryption without weakening’

The two major international security agencies in Europe agree that building backdoors into encryption platforms is not the best way to secure systems because of the collateral damage it would do to privacy and the security of communications.“While this would give investigators lawful access in the event of serious crimes or terrorist threats, it would also increase the attack surface for malicious abuse, which, consequently, would have much wider implications for society,” says a joint statement by European Police Office (Europol) and European Network and Information Security Agency (ENISA), which focuses on cyber security.To read this article in full or to leave a comment, please click here

Microsoft eats another $1B as phone strategy shrinks to enterprise-only

Microsoft's announcement yesterday that it would eat nearly $1 billion and lay off another 1,850 workers, three-quarters of them from its phone division, prompted analysts to call the company's consumer smartphone business dead, deceased, departed.They agreed that Microsoft's only remaining shot at phones is the enterprise, probably with a "Surface"-branded model that apes the Surface Pro as a design benchmark that struts Windows' capabilities."They've discarded consumer," said Patrick Moorhead, principal analyst at Moor Insights & Strategy, in an interview. "They just tossed out the Windows fan. It's now all about business."Moorhead and others based their opinions on statements made in mid-2015 by CEO Satya Nadella, who spelled out three markets for Microsoft's smartphones after he announced a retrenchment and a massive $7.6 billion write-off for the failed acquisition of Nokia under his predecessor, Steve Ballmer.To read this article in full or to leave a comment, please click here

IT wants (but struggles) to operationalize big data

Big data leaders at large companies are confident their big data strategies are headed in the right direction, but most also feel that they're struggling to operationalize them, according to a new survey."Big data is not going away. It's increasing in momentum. People are starting to understand the different types of use cases and move things from prototyping into production," says Stephen Baker, CEO of Attivio, a company that helps customers catalog and leverage all the data at their disposal. "But there are challenges for sure: Challenges in terms of hiring the right kinds of resources, challenges around organizationally changing the way people behave. There's this concept of Shadow BI."To read this article in full or to leave a comment, please click here

Google may publicly shame phone makers who deliver tardy Android updates: report says

Google may have finally had enough.According to a Bloomberg report, the company is thinking about turning to public shaming as a way to entice handset manufacturers to step up their Android updates. Google has apparently collected considerable data (something it’s very good at) regarding manufacturers and carriers’ update performance and shared this information with OEMs and carriers. A Sprint executive said he’d seen the details and had been feeling the pressure from Google to push things along.Even without access to this information, we can assure you it isn’t a pretty picture: only 7.5 percent of the current Android devices are running Marshmallow, which is the latest major version. This after about half a year on the market. Some are slower than others, while the wireless providers have also been known to hold things up for “carrier testing.” To read this article in full or to leave a comment, please click here

Startup CEO agrees to $560K settlement to make long list of fraud allegations go away

Bob Ambrogi, who writes a terrific blog about technology and the law, today has posted remarkable details of a lawsuit settlement involving the head of a legal startup and a couple who allege he scammed them out of hundreds of thousands of dollars through, among other means, falsely claiming to be a lawyer, forging legal documents, fabricating court cases and even conjuring up a non-existent judge. The executive, Derek Bluford – CEO of California Legal Pros and QuickLegal – says in the settlement document that he “does not admit that any of the allegations set forth in the complaint are true or valid.” Ambrogi made that point twice so I will, too. Bluford did agree to pay the plaintiffs, Changming Liu and Aimei Wei, $559,330. The couple had enlisted the services of Bluford and California Legal Pros in 2014 to help them evict a tenant.    To read this article in full or to leave a comment, please click here
