Reddit: Redirect all incoming and outgoing traffic from a port to a specific ip

Monday 18th of June 2018 01:15:49 PM

I am running a node server inside a docker container on port 8080 and i can access it via 172.17.0.2:8080 (container ip) now i want to access this ip from localhost:9099.

I have tried using iptables to redirect this traffic coming at localhost:9099 to 172.17.0.2:8080 but all measures are in vain.

This is the command i was using. Please correct me where i am going wrong. Thanks in advance.

sudo iptables -t nat -A PREROUTING -p tcp --dport 9099 -j DNAT --to-destination 172.17.0.2:8080

I referred to this (https://stackoverflow.com/questions/19897743/exposing-a-port-on-a-live-docker-container) ans but didn't work out.

Phoronix: Using W10Privacy To Boost Ubuntu WSL Performance On Windows 10

Monday 18th of June 2018 01:09:17 PM
While Microsoft is working on low-level improvement to the Windows Subsystem for Linux (WSL) to yield better I/O performance, it is possible to dramatically increase some disk workloads by removing a number of running Windows services via the independent W10Privacy application. Here are some benchmarks of W10Privacy on the overall performance impact to Microsoft Windows 10 Pro x64 itself and of Ubuntu 18.04 running on the Windows 10 installation via WSL.

Reddit: DD-CLI-HELPER and VBOXMANAGE-CLI-HELPER

Monday 18th of June 2018 01:08:27 PM

Hey everyone. I'm a noob to bash scripting, but I made a bash front end for helping use DD to clone disks, restore images, and backup disks.

https://gitlab.com/tj_v_debs/dd-helper

I also made a virtualbox cli helper for cloning disks, converting them to a different format, and creating the raw vmdk file for physical disk access.

https://gitlab.com/tj_v_debs/Vboxmanage-cli-helper

Check em out and tell me what yall think and how I could improve. Trying to figure out how to implement a file browser without having to make one myself lol.

LXer: 5 open source alternatives to Dropbox

Monday 18th of June 2018 11:50:31 AM
Dropbox is the 800-pound gorilla of filesharing applications. Even it's a massively popular tool, you may choose to use an alternative.Maybe that's because you're dedicated to the open source way for all the good reasons, including security and freedom, or possibly you've been spooked by data breaches. Or perhaps the pricing plan doesn't work out in your favor for the amount of storage you actually need.read more

Reddit: Where to start with learning security with Linux?

Monday 18th of June 2018 11:27:41 AM

I've looked through some of the stuff here and googled a bit, but there's a lot of info out there.

I'm brand new to security. I'm getting an old Thinkpad to learn more about security and how to make a crack-resistant system. I want to know where I should start? What books should I read as a beginner?

A bit of background about myself: I'm a teacher in China, and I do some web development on the side. I want to expand my knowledge into security, and I want to go deeper than the basics.

TuxMachines: 5 open source alternatives to Dropbox

Monday 18th of June 2018 08:42:06 AM

Dropbox is the 800-pound gorilla of filesharing applications. Even it's a massively popular tool, you may choose to use an alternative.

Maybe that's because you're dedicated to the open source way for all the good reasons, including security and freedom, or possibly you've been spooked by data breaches. Or perhaps the pricing plan doesn't work out in your favor for the amount of storage you actually need.

Fortunately, there are a variety of open source filesharing applications out there that give you more storage, security, and control over your data at a far lower price than Dropbox charges. How much lower? Try free, if you're a bit tech savvy and have a Linux server to use.

Linux Kernel and Security: LVM2, Containers, AMD

  • LVM2 Begins Work On Major Changes To Logical Volume Management
    LVM2 as the user-space tools for Logical Volume Management (LVM) on Linux is in the process of going through a big re-work.
  • Containers and Cloud Security
    The idea behind this blog post is to take a new look at how cloud security is measured and what its impact is on the various actors in the cloud ecosystem. From the measurement point of view, we look at the vertical stack: all code that is traversed to provide a service all the way from input web request to database update to output response potentially contains bugs; the bug density is variable for the different components but the more code you traverse the higher your chance of exposure to exploitable vulnerabilities. We’ll call this the Vertical Attack Profile (VAP) of the stack. However, even this axis is too narrow because the primary actors are the cloud tenant and the cloud service provider (CSP). In an IaaS cloud, part of the vertical profile belongs to the tenant (The guest kernel, guest OS and application) and part (the hypervisor and host OS) belong to the CSP. However, the CSP vertical has the additional problem that any exploit in this piece of the stack can be used to jump into either the host itself or any of the other tenant virtual machines running on the host. We’ll call this exploit causing a failure of containment the Horizontal Attack Profile (HAP). We should also note that any Horizontal Security failure is a potentially business destroying event for the CSP, so they care deeply about preventing them. Conversely any exploit occurring in the VAP owned by the Tenant can be seen by the CSP as a tenant only problem and one which the Tenant is responsible for locating and fixing. We correlate size of profile with attack risk, so the large the profile the greater the probability of being exploited.
  • Canonical Releases AMD Microcode Updates for All Ubuntu Users to Fix Spectre V2
    Canonical released a microcode update for all Ubuntu users with AMD processors to address the well-known Spectre security vulnerability. The Spectre microprocessor side-channel vulnerabilities were publicly disclosed earlier this year and discovered to affect billions of devices made in the past two decades. Unearthed by Jann Horn of Google Project Zero, the second variant (CVE-2017-5715) of the Spectre vulnerability is described as a branch target injection attack.

Programming: 5 Pillars of Learning Programming, New Releases of Rust and Git

  • 5 Pillars of Learning Programming
    Learning how to program is hard. I often find that university courses and boot camps miss important aspects of programming and take poor approaches to teaching rookies. I want to share the 5 basic pillars I believe a successful programming course should build upon. As always, I am addressing the context of mainstream web applications. A rookie’s goal is to master the fundamentals of programming and to understand the importance of libraries and frameworks. Advanced topics such as the cloud, operations in general, or build tools should not be part of the curriculum. I am also skeptical when it comes to Design Patterns. They presume experience that beginners never have.
  • The Rust Programming Language Blog: Announcing Rust 1.27
    The Rust team is happy to announce a new version of Rust, 1.27.0. Rust is a systems programming language focused on safety, speed, and concurrency.
  • Rust 1.27 Released With SIMD Improvements
    Most notable to Rust 1.27 is SIMD support via the std::arch module to make use of SIMD (Single Instruction, Multiple Data) instructions directly. Up to now Rust could already make use of LLVM's auto-vectorization support, but this lets Rust developers write SIMD instructions on their own and to allow for the proper Rust code to be executed based upon the CPU at run-time.
  • Git 2.18 Released With Initial Version Of Its New Wire Protocol
    Version 2.18 of the Git distributed revision control system is now available. Arguably most notable about Git 2.18 is the introduction of its new wire protocol "protocol_v2" that is designed to offer much greater performance. This new protocol is designed to be much faster and is already being used at Google and elsewhere due to the significant performance benefits.
  • Git v2.18.0
    The latest feature release Git v2.18.0 is now available at the usual places. It is comprised of 903 non-merge commits since v2.17.0, contributed by 80 people, 24 of which are new faces.

Linux Foundation: Heather Kirksey and the New LF Report

  • Heather Kirksey on Integrating Networking and Cloud Native
    As highlighted in the recent Open Source Jobs Report, cloud and networking skills are in high demand. And, if you want to hear about the latest networking developments, there is no one better to talk with than Heather Kirksey, VP, Community and Ecosystem Development, Networking at The Linux Foundation. Kirksey was the Director of OPNFV before the recent consolidation of several networking-related projects under the new LF Networking umbrella, and I spoke with her to learn more about LF Networking (LFN) and how the initiative is working closely with cloud native technologies. Kirksey explained the reasoning behind the move and expansion of her role. “At OPNFV, we were focused on integration and end-to-end testing across the LFN projects. We had interaction with all of those communities. At the same time, we were separate legal entities, and things like that created more barriers to collaboration. Now, it’s easy to look at them more strategically as a portfolio to facilitate member engagement and deliver solutions to service providers.”
  • Linux Skills Most Wanted: Open Source Jobs Report
    The 2018 Open Source Technology Jobs Report shows rapid growth in the demand for open source technical talent, with Linux skills a must-have requirement for entry-level positions. The seventh annual report from The Linux Foundation and Dice, released Wednesday, identifies Linux coding as the most sought-after open source skill. Linux-based container technology is a close second. The report provides an overview of open source career trends, factors motivating professionals in the industry, and ways employers attract and retain qualified talent. As with the last two open source jobs reports, the focus this year is on all aspects of open source software and is not limited to Linux.
