Meet Three APrIGF 2019 Fellows

The Internet Society, APNIC, and Coordination Center for TLD .RU sponsored 20 fellows to the 10th Asia Pacific Regional Internet Governance Forum (APrIGF 2019) held in Vladivostok, Russia in July. Let’s meet three fellows from Bangladesh, Myanmar, and Singapore as they share their experience at APrIGF 2019, as well as their interests and future aspirations.

Shah Zahidur Rahman, Technology Business Consultant, Bangladesh

I completed my Bachelor’s degree in Computer Science and Engineering from the American International University-Bangladesh and have many technical course certifications. Currently, I am a technology business consultant for small- and medium-sized enterprises and startup companies. I have also been mentoring youths in the Youth4IG coalition to become further engaged in Internet Governance issues. I have been an active member of the Internet Society Bangladesh Chapter since 2014. I am also a member of the Bangladesh School of Internet Governance Programme Committee and Fellowship Committee, the Bangladesh Internet Governance Forum, and the ICANN Non-Commercial Stakeholder Group and Non-Commercial Users Constituency. Additionally, I am a former fellow of IETF, APSIG and APAN.

This year at APrIGF 2019, my main interest was in one of the six subthemes on Emerging Technologies and Society, and here are some of the key things I learned Continue reading

Day Two Cloud 020: Design Tips For Cloud Networking Success

VPCs. Vnets. DirectConnect. Kubernetes. Calico. Public clouds. Hybrid clouds. Networking is no small feat when it comes to the cloud. How does an organization keep their cloud networks from turning into a flying spaghetti monster? Day Two Cloud tackles this critical question with guest Andrew Wertkin, Chief Strategy Officer at BlueCat Networks. We discuss design tips, the critical role of DNS, monitoring and troubleshooting options, and more.

vSAN Stretched Cluster Using an NSX-T Backed L3 Network

VMware vSAN and NSX-T Compatibility 

There are lot of discussions that talk about VMware NSX and VMware vSAN, most of them around compatibility.

vSAN and NSX are compatible with each other, however, vSAN traffic is not supported on NSX overlay network. But, the way VDS Portgroups can be used to configure vSAN vmkernel adapters, NSX-T VLAN backed logical switches can also be used to configure vSAN vmkernel adapters. Apart from this, NSX-T logical routers can be used as gateways to route the vSAN traffic, of course the backing for such configuration must be with NSX-T VLAN logical switches.

In this blog post I cover how NSX-T can be used to setup configuration for vSAN stretched cluster.

Deep Dive of vSAN Stretched Cluster Using an NSX-T Backed L3 Network

One of the configurations for vSAN stretched cluster can be achieved with L3 networking between Data Nodes and the Witness Host. In such deployment, the Data Nodes and Witness Host may reside in different networks. Hence, the vSAN vmkernel adapters need to point to their gateways to talk to each other. Following is the high-level network view of such topology for vSAN stretched cluster where hosts use VDS Portgroups to configure the Continue reading

How inspiration from your data center can modernize your campus network.

Campus networks are undergoing a rapid evolution as they draw inspiration from their data center peers from both a technology and cost perspective. At the forefront of this evolution is open networking, led by innovation and cost efficiencies that apply equally across data center and campus networks.

Interestingly, Cumulus Linux was originally intended for data center networking, but without a doubt, we’re seeing the lines between data center and campus blurring with campus standing to benefit significantly, and it’s about time. It’s the data center that has historically benefited from innovation, especially in compute and storage. The data center network, however, seemed to lag for more than a decade until our founders set out in 2010 to develop a fundamentally different approach to the data center with Cumulus Networks.

Cumulus Networks introduced an open, modern and innovative network operating system called Cumulus Linux. Cumulus Linux was originally designed to emulate the network architecture of the web-scale giants including Google, Amazon, Apple, Microsoft and Facebook allowing you to automate, customize and scale your data center network like no other, and for the first time, bringing this capability to the masses.

Cumulus Networks is building the modern data center network for applications Continue reading

How Did We End with 1500-byte MTU?

A subscriber sent me this intriguing question:

Is it not theoretically possible for Ethernet frames to be 64k long if ASIC vendors simply bothered or decided to design/make chipsets that supported it? How did we end up in the 1.5k neighborhood? In whose best interest did this happen?

Remember that Ethernet started as a shared-cable 10 Mbps technology. Transmitting a 64k frame on that technology would take approximately 50 msec (or as long as getting from East Coast to West Coast). Also, Ethernet had no tight media access control like Token Ring, so it would be possible for a single host to transmit multiple frames without anyone else getting airtime, resulting in unacceptable delays.

“I was told to buy a software or lose my computer: I ignored it.” A study of ransomware

“I was told to buy a software or lose my computer. I ignored it”: a study of ransomware Simoiu et al., SOUPS 2019

This is a very easy to digest paper shedding light on the prevalence of ransomware and the characteristics of those most likely to be vulnerable to it. The data comes from a survey of 1,180 US adults conducted by YouGov, an online global market research firm. YouGov works hard to ensure respondent participation representative of (in this case) the general population in the U.S., but the normal caveats apply.

We define ransomware as the class of malware that attempts to defraud users by restricting access to the user’s computer or data, typically by locking the computer or encrypting data. There are thousands of different ransomware strains in existence today, varying in design and sophistication.

The survey takes just under 10 minutes to complete, and goes to some lengths to ensure that self-reporting victims really were victims of ransomware (and not some other computer problem).

For respondents that indicated they had suffered from a ransomware attack, data was collected on month and year, the name of the ransomware variant, the ransom demanded, the payment method, Continue reading

How to prevent IPv6 VPN breakout

Enterprises unaware of the role IPv6 plays on remote users’ devices run the risk that these machines might access banned sites despite using VPNs that are meant to restrict what they access.This hole stems from the fact that some of these remote-access VPNs are configured to inspect and apply security controls only to IPv4 traffic as it passes through a VPN concentrator without enabling similar protections for IPv6 traffic.[Get regularly scheduled insights by signing up for Network World newsletters.] This leaves IPv6 traffic free to access the Internet directly without those controls being applied. Known as IPv6 VPN breakout, the issue is well known yet often remains overlooked.To read this article in full, please click here

Linux sudo flaw can lead to unauthorized privileges

A newly discovered and serious flaw in the sudo command can, if exploited, enable users to run commands as root in spite of the fact that the syntax of the  /etc/sudoers file specifically disallows them from doing so.Updating sudo to version 1.8.28 should address the problem, and Linux admins are encouraged to do so as soon as possible. [Get regularly scheduled insights by signing up for Network World newsletters.] How the flaw might be exploited depends on specific privileges granted in the /etc/sudoers file. A rule that allows a user to edit files as any user except root, for example, would actually allow that user to edit files as root as well. In this case, the flaw could lead to very serious problems.To read this article in full, please click here
