Linux systems: Scraping up information about apt updates

When you use the apt command to install new packages or run routine upgrades on your Debian-based Linux system, you might wonder where information about your activities are being recorded. For one, your history file probably retains information on the commands that you use, though history files like ~/.bash_history will only keep the most recent commands that you've run — depending on your $HISTSIZE setting — and generally will not include dates and times. There is, however, another place to find information about apt commands and that place is /var/log/apt.The /var/log/apt directory contains a number of log files — the history.log file, plus a series of older versions of the file named history.log.1.gz, history.log.2.gz, history.log.3,gz and so on. Each of these logs will contain information on apt commands that have been run within a particular timeframe.To read this article in full, please click here

Huawei introduces AI-driven data center switch

Chinese telecom giant Huawei introduced a new data center switch powered by an artificial intelligence (AI) chip designed to improve performance and reduce latency to near zero. The new switch follows the announcement of a 64-core ARM server processor.The CloudEngine 16800 series of data center switches use AI to improve network operations and also provide an underlying network foundation for companies to build new apps that utilize AI for network performance.Huawei claims the CloudEngine 16800 is the first data center switch use an embedded AI chip, using the iLossless algorithm to implement auto-sensing and auto-optimization of the traffic model, thereby lowering latency and providing higher throughput based on zero packet loss.To read this article in full, please click here

Optimism around 5G may be strong for now, but service providers are finding it difficult to convey a feasible business case for the technology as average consumers remain ill-informed of its true benefits. 61% of respondents were hopeful about the overall availability of 5G coming in the next two years, however, 40% don’t believe consumers will be willing to pay more for the privilege. —Sigal Biran-Nagar

DNS security from the client perspective is a one-hour online course examining both technical and managerial topics associated with the security of the Domain Name System.

Understanding the JunOS routing table

I was just about to finish another blog post on MPLS when I got a question from a colleague about Junos routing tables. He was confused as to how to interpret the output of a basic Juniper routing table. I spent some time trying to find some resource to point him at – and was amazed at how hard it was to find anything that answered his questions specifically. Sure, there are lots of blogs and articles that explain RIB/FIB separation, but I couldn’t find any that backed it up with examples and the level of detail he was looking for. So while this is not meant to be exhaustive – I hope it might provide you some details about how to interpret the output of some of the more popular show commands. This might be especially relevant for those of you who might be coming from more of a Cisco background (like myself a number of years ago) as there are significant differences between the two vendors in this area.

Let’s start with a basic lab that looks a lot like the one I’ve been using in the previous MPLS posts…

For the sake of focusing on the real Continue reading

The SamKnows Cloudflare Platform

This is a guest post by Jamie Mason, who is the Head of Test Servers at SamKnows. This post originally appears on the SamKnows Megablog.

We leveraged Cloudflare Workers to expand the SamKnows measurement infrastructure.

At SamKnows, we run lots of tests to measure internet performance. Actually, that’s an understatement. Our software is embedded on tens of millions of devices, and that number grows daily.

We measure performance between the user’s home and the internet, across dozens of metrics. Some of these metrics measure the performance of major video-streaming services, popular games, or large websites. Others focus on the more traditional ‘quality of service’ metrics: speed, latency, and packet loss.

In order to measure speed, latency, and packet loss, SamKnows needs test servers to carry out the measurements against. These servers should be relatively near to the user’s home - this ensures that we’re measuring solely the user’s internet connection (i.e. what their Internet Service Provider sells them) and not some external factor.

As a result, we manage high-capacity test servers all over the world. Some are donated by research groups, some we host ourselves in major data centers, and still others are run inside ISPs’ own networks.

Consumer Electronics Show: Everything’s Connected, But What About Security and Privacy?

We spent last week at the Consumer Electronics Show (aka CES) in Las Vegas, with over 180,000 of our closest friends. And with 4,500 exhibitors present, you’d have less than 30 seconds at each booth if you wanted to talk to all of them. Many articles have covered the cool new things, so in this blogpost we are going to discuss our overall impressions as they relate to our work on consumer IoT security and privacy.

Not surprisingly, there were many interesting conference sessions and a wide variety of innovative products on display, including some that seemed to push the bounds of credibility in their claims. Integration of devices with voice-driven and other platforms was everywhere – Amazon Alexa, Google Assistant, Apple HomeKit, and Samsung SmartThings being the most widely adopted to date. 5G was a hot topic, especially for its improved speeds and flexibility, though specifics about its availability are still hard to pin down.

Everything these days is getting connected to the Internet – from cat toys to sports simulators to home automation. One area that seems to be gaining more traction because it has gone beyond the “gadget” stage and is solving real problems is health and Continue reading

Short Take – HTTPS Interception

HTTPS was created to ensure end to end encryption of web traffic but both good guys and attackers circumvent this with man-in-the-middle interception. In this Short Take, Russ talks about some of the mechanics of HTTPS interception as well as some implications of doing it intentionally.
