Overview Of tcpdump With Examples

Filed under
Linux

You can view information about traffic coming and going from a given network interface using tcpdump. This diagnostic tool allows you to see packet information, that is where incoming packets come from and where outgoing packets are heading to on an interface, with some extra information. You can even save the output to a file to inspect later on. This article will demonstrate the simple examples of tcpdump.

  • State of Linux Containers

    In this video from the Stanford HPC Conference, Christian Kniep from Docker Inc. presents: State of Containers.

    “This talk will recap the history of and what constitutes Linux Containers, before laying out how the technology is employed by various engines and what problems these engines have to solve. Afterward, Christian will elaborate on why the advent of standards for images and runtimes moved the discussion from building and distributing containers to orchestrating containerized applications at scale. In conclusion, attendees will get an update on what problems still hinder the adoption of containers for distributed high performance workloads and how Docker is addressing these issues.”

  • ONS 2018: Networking Reimagined

    For the past seven years, Open Networking Summit (ONS) has brought together the networking industry’s ecosystem of network operators, vendors, open source projects, leading researchers, and investors to discuss the latest SDN and NFV developments that will shape the future of the networking industry. With this year’s event, taking place March 26-29, 2018 in Los Angeles, ONS will evolve its approach as the premier open source networking event. We’re excited to share three new aspects of this year’s ONS that you won’t want to miss:

  • AT&T contributes code to Linux open source edge computing project

    The Linux Foundation recently announced a new project, dubbed Akraino, to develop an open source software stack capable of supporting high-availability cloud services for edge computing systems and applications. To kick off the project, AT&T will contribute code made for carrier-scale edge computing applications running in virtual machines and containers.

  • AT&T Brings Akraino Networking Project to Edge of the Linux Foundation

    The Linux Foundation has been particularly busy in 2018 thus far consolidating its existing networking project under a single umbrella, known as LF Networking. That umbrella might need to get a bit larger, as on Feb. 20 the Linux Foundation announced the new Akraino project, with code coming initially from AT&T.

  • FreeOffice 2016 – An Efficient Alternative to Microsoft Office

    FreeOffice 2016 is the latest version of the Office software from SoftMaker. In fact, you wouldn’t be wrong if you called it the free version of SoftMaker Office 2018 seeing as it features the same suite of applications.

  • Stellaris 2.0 'Cherryh' patch & Stellaris: Apocalypse expansion released, over 1.5 million copies sold

    Stellaris: Apocalypse [Steam], the latest expansion for the grand space strategy game from Paradox Development Studio is out. The big 2.0 'Cherryh' patch is also now available.

    Paradox has also announced today, that Stellaris has officially passed 1.5 million copies sold making it one of their most popular games ever made. I'm not surprised by this, as I consider Stellaris their most accessible game.

  • Action-packed platformer with local and online co-op 'Vagante' has left Early Access

    After being in Early Access for quite some time, the action-packed platformer 'Vagante' [Steam, Official Site] has now officially left Early Access.

  • Gentoo has been accepted as a Google Summer of Code 2018 mentoring organization
  • Getting Debian booting on a Lenovo Yoga 720

    I recently got a new work laptop, a 13” Yoga 720. It proved difficult to install Debian on; pressing F12 would get a boot menu allowing me to select a USB stick I have EFI GRUB on, but after GRUB loaded the kernel and the initrd it would just sit there never outputting anything else that indicated the kernel was even starting. I found instructions about Ubuntu 17.10 which helped but weren’t the complete picture. What seems to be the situation is that the kernel won’t happily boot if “Legacy Support” is not enabled - enabling this (and still booting as EFI) results in a happier experience.

  • Dell PowerEdge T30

    I just did a Debian install on a Dell PowerEdge T30 for a client. The Dell web site is a bit broken at the moment, it didn’t list the price of that server or give useful specs when I was ordering it. I was under the impression that the server was limited to 8G of RAM, that’s unusually small but it wouldn’t be the first time a vendor crippled a low end model to drive sales of more expensive systems. It turned out that the T30 model I got has 4*DDR4 sockets with only one used for an 8G DIMM. It apparently can handle up to 64G of RAM.

  • Quad-Ethernet SBC and controller tap new Renesas RZ/N1D SoC

    Emtrion’s Linux-ready “SBC-RZN1D” SBC, which will soon power a “Flex2COM” controller, features a Renesas dual-core -A7 RZ/N1D SoC and 4x LAN ports, and is designed for multi-protocol fieldbus communications.

    Emtrion, which recently announced its emCON-RZ/G1H module based on an octa-core Renesas RZ/G1H SoC, has unveiled a Renesas based, quad-LAN port SBC-RZN1D SBC focused on industrial communication. The SBC-RZN1D taps the Renesas RZ/N1D (R9006G032), one of a new line of RZ/N1D SoCs launched last year by Renesas for industrial multi-protocol communications. Renesas recently collaborated with Avnet to ship its own dual-Ethernet Renesas RZ/N1D Solution Kit (see farther below).

  • Postage-Stamp Linux

    There was a time when big operating systems ran on big iron. IBM, Data General, Burroughs, DEC, and other computer makers built big machines with big, blinking lights, and big price tags. They ran grown-up software and they supported multiuser operating systems. If you wanted a toy, you built a microcomputer. If you wanted a real machine for serious work, you bought a mainframe. Maybe a minicomputer, if it were for lesser tasks.

  • Most Popular Android Versions In February 2018 (Always Updated List)

    Android is the most used operating system on the planet. In fact, it’s almost omnipresent in the mobile ecosystem. Even the Android versions, like Nougat, Marshmallow, Lollipop, etc. have been able to build their individual fan following.

  • Red Hat’s David Egts: Microservices Tech Could Help Simplify App Deployment

    David Egts, chief technologist for Red Hat’s public sector, told MeriTalk in an interview published Wednesday that the microservices technology works to help the developer split complex, large applications into small components and share them with other members of the DevOps team.

  • Radcom partners with Red Hat for NFV management

    Radcom announced it is collaborating with Red Hat to provide operators with a fully virtualized network visibility solution running on Red Hat OpenStack Platform. As operators transition to NFV, a critical first step is gaining end-to-end network visibility. This collaboration enables operators to attain cloud-native network visibility without the hassle of building their own private cloud infrastructure, the vendor said. Once the operator's transition to NFV matures, integration efforts with the NFV and MANO infrastructure can be simplified.

  • Justin W. Flory: Humanitarian open source work: My internship at UNICEF

    In December, I received the happy news of an offer for a internship position at UNICEF in the Office of Innovation. The Office of Innovation drives rapid technological innovation by rapid prototyping of new ideas and building full-stack products to make a positive impact in the lives of children. This is a simple answer, but a more detailed description is on our website.

    My internship at UNICEF is unique: I support open source community engagement and research as my primary task for the MagicBox project. For years, I’ve done this in open source communities in my free time (namely SpigotMC and Fedora), but never in a professional role. As I navigate my way through this exciting opportunity, I plan to document some of the experience as I go through blogging. My intent is that my observations and notes will be useful to someone else in the humanitarian open source space (or maybe to a future me).

  • Fedora participating in Google Summer of Code 2018

    GSoC is a summer program aiming to bring more student developers into open source software development. It enables students to spend their summer break working with open source organizations on projects proposed by participating organizations and supported by mentors.

  • FOSS Wave with Fedora at KGISL, Coimbatore

    Recently, I was invited by Prem to NASSCOM to give a brief talk on FOSS and Technology as part of the FOSS Wave community. Prem is doing a great job there by putting his effort in helping students from Tier2 and Tier3 cities. Around twenty enthusiastic students were selected and invited to Bengaluru to take part in such events. Mine was one of them. I conducted a GitHub session after Intro to FOSS and a brief intro about Fedora Project.

  • Comment: Many happy returns to open source

    Twenty years ago the phrase “open source” was first used and the development of software – and hardware – was changed forever.

    Very few designers today will not use some element of open source software in their development projects.

  • Worth seeing in Barcelona: Open source for white box vRAN solutions

    News this week from cloud and carrier infrastructure platform company Kontron builds on our earlier coverage of the emerging virtual radio access network (vRAN); a promising technology that could help the evolution to 5G by maximising available bandwidth while lowering costs. The market for open vRAN solutions is gaining wider acceptance as operators seek more cost-effective approaches to network architectures and deployment. According to analyst firm Research and Markets, the growth of the vRAN market is expected to grow at a CAGR of approximately 125 per cent during the next three years.

    Published in Gigascience, the open source Galaxy workflow aims to make researchers job of finding find gene families much easier.

  • 3 reasons to say 'no' in DevOps

    DevOps, it has often been pointed out, is a culture that emphasizes mutual respect, cooperation, continual improvement, and aligning responsibility with authority.

    Instead of saying no, it may be helpful to take a hint from improv comedy and say, "Yes, and..." or "Yes, but...". This opens the request from the binary nature of "yes" and "no" toward having a nuanced discussion around priority, capacity, and responsibility.

  • 5 rules for having genuine community relationships

    As I wrote in the first article of this three-part series on the power and importance of communities, building a community of passionate and committed members is difficult. When we launched the NethServer community, we realized early that to play the open source game, we needed to follow the open source rules. No shortcuts. We realized we had to convert the company in an open organization and start to work out in the open.

  • Rust Typestates

    A long time ago, the Rust language was a language with typestate. Officially, typestates were dropped long before Rust 1.0. In this entry, I’ll get you in on the worst kept secret of the Rust community: Rust still has typestates.

  • It's Time To Do CMake Right

    Not so long ago I got the task of rethinking our build system. The idea was to evaluate existing components, dependencies, but most importantly, to establish a superior design by making use of modern CMake features and paradigms. Most people I know would have avoided such enterprise at all costs, but there is something about writing find modules that makes my brain release endorphins. I thought I was up for an amusing ride. Boy was I wrong.

  • OpenBSD Gets Mitigated For Meltdown CPU Vulnerability

    A few days back FreeBSD 11 stable was mitigated for Meltdown (and Spectre vulnerabilities), which came more than one month after these nasty CPU vulnerabilities were disclosed while DragonFlyBSD was quickly mitigated and the first of the BSDs to do so. While OpenBSD is known for its security features and focus, only today did it land its initial Meltdown mitigation.

  • Meltdown fix committed by guenther@

    Meltdown mitigation is coming to OpenBSD. Philip Guenther (guenther@) has just committed a diff that implements a new mitigation technique to OpenBSD: Separation of page tables for kernel and userland. This fixes the Meltdown problems that affect most CPUs from Intel. Both Philip and Mike Larkin (mlarkin@) spent a lot of time implementing this solution, talking to various people from other projects on best approaches.

    In the commit message, Philip briefly describes the implementation [...]

France Proposes Software Security Liability For Manufacturers, Open Source As Support Ends

OSS
Security

It sometimes seems as though barely a week can go by without yet another major software-related hardware vulnerability story. As manufacturers grapple with the demands of no longer building simple appliances but instead supplying them containing software that may expose itself to the world over the Internet, we see devices shipped with insecure firmware and little care for its support or updating after the sale.

The French government have a proposal to address this problem that may be of interest to our community, to make manufacturers liable for the security of a product while it is on the market, and with the possibility of requiring its software to be made open-source at end-of-life. In the first instance it can only be a good thing for device security to be put at the top of a manufacturer’s agenda, and in the second the ready availability of source code would present reverse engineers with a bonanza.

  • Removing Support for Unpacked Extensions

    With the release of Firefox 62 (currently scheduled for August 21, 2018) Mozilla will discontinue support for unpacked sideloaded extensions. You will no longer be able to load an extension via the Windows registry by creating an entry with an extension’s directory (i.e. unpacked) after Firefox 61. Starting with Firefox 62, extensions sideloaded via the Windows registry must be complete XPI files (i.e. packed).

  • Making a Clap-Sensing Web Thing

    The Project Things Gateway exists as a platform to bring all of your IoT devices together under a unified umbrella, using a standardized HTTP-based API. We recently announced the Things Gateway and we’ve started a series of hands-on project posts for people who want to set up a Gateway and start playing around with the Web of Things. Earlier this month we began with a high-level overview of how to build a Gateway add-on.

  • Trying Mozilla's Things Gateway

    I have an old Raspberry Pi 1 Model B with a RaZberry Z-Wave Daughterboard which I had soldered a larger external antenna on to last year. I used to run OpenHAB on it to control some z-wave devices before I moved last year and since then it's just been in a box. Let's fire it up!

    This original Raspberry Pi is a single core 700mhz CPU, so I'm planning on running it headless and doing everything remotely over SSH to save on GUI resources.

  • Lando Demo

    Lando is so close now that I can practically smell the tibanna. Israel put together a quick demo of Phabricator/BMO/Lando/hg running on his local system, which is only a few patches away from being a deployed reality.

  • Snips Uses Rust to Build an Embedded Voice Assistant

    The team at Paris-based Snips has created a voice assistant that can be embedded in a single device or used in a home network to control lights, thermostat, music, and more. You can build a home hub on a Raspberry Pi and ask it for a weather report, to play your favorite song, or to brew up a double espresso. Manufacturers like Keecker are adding Snips’ technology to products like multimedia home robots. And Snips works closely with leaders across the value chain, like NVIDIA, EBV, and Analog Devices, in order to voice-enable an increasingly wider range of device types, from speakers to home automation systems to cars.

  • Mozilla v FCC: Mozilla Re-files Suit Against FCC to Protect Net Neutrality

    This morning, the Federal Communications Commission officially published its order overturning net neutrality rules in the Federal Register. We had originally filed suit early while simultaneously urging the court that the correct date was after this publication. We did this in an abundance of caution because we’re not taking any chances with an issue of this importance. That is why today, immediately after the order was published, Mozilla re-filed our suit challenging the FCC net neutrality order. We won’t waste a minute in our fight to protect net neutrality because it’s our mission to ensure the internet is a global public resource, open and accessible to all. An internet that truly puts people first, where individuals can shape their own experience and are empowered, safe and independent.

  • The Death Of Net Neutrality Will Be Official In April (Cue The Lawsuits)

    Of course that's really just the beginning of an entirely new chapter in the fight to prevent broadband monopolies from abusing a lack of competition in the broadband space (remember: net neutrality violations are just a symptom of a lack of competition, a problem nobody wants to seriously address for fear of upsetting campaign contributors).

    The publication in the Federal Register opens the door to the myriad lawsuits that will be filed against the agency. Those lawsuits range from suits by Mozilla and consumer groups, to the 22 state attorneys general who say they're also suing the agency for ignoring the public interest. These lawsuits must be filed within the next 60 days. Expect the court battle to quickly begin heating up in March.

Besides bringing Ubuntu Touch to new mobile devices, the UBports team has also managed to continue their community-driven work on advancing the Unity 8 convergence desktop after Canonical abandoned work on it last year. They now have Unity 8 working on top of Ubuntu 18.04 LTS.

The UBPorts' fork of Unity 8 is now working on Ubuntu 18.04 LTS where as previously they were focused on older versions of Ubuntu. Installation instructions can be found via this GitHub repository with this being work found outside of the official Ubuntu archives. Ubuntu 16.04 LTS and 18.04 LTS users can make use of the project's install scripts where they have assembled an APT archive with their own packages of Unity 8 complete with Mir.

  • Linux Adds CH341 GPIO

    There was a time when USB to serial hardware meant one company: FTDI. But today there are quite a few to choose from and one of the most common ones is the WCH CH341. There’s been support for these chips in Linux for a while, but only for use as a communication port. The device actually has RS232, I2C, SPI, and 8 general purpose I/O (GPIO) pins. [ZooBaB] took an out-of-tree driver that exposes the GPIO, and got it working with some frightening-looking CH341 boards.

  • Shrinking the kernel with an axe

    This is the third article of a series discussing various methods of reducing the size of the Linux kernel to make it suitable for small environments. The first article provided a short rationale for this topic, and covered link-time garbage collection. The second article covered link-time optimization (LTO) and compared its results to link-time garbage collection. In this article we'll explore ways to make LTO more effective at optimizing kernel code away, as well as more assertive strategies to achieve our goal.

  • The rest of the 4.16 merge window

    At the close of the 4.16 merge window, 11,746 non-merge changesets had been merged; that is 5,000 since last week's summary. This merge window is thus a busy one, though not out of line with its predecessors — 4.14 had 11,500 changesets during its merge window, while 4.15 had 12,599. Quite a bit of that work is of the boring internal variety; over 600 of those changesets were device-tree updates, for example. But there was still a fair amount of interesting work merged in the second half of the 4.16 merge window; read on for the highlights.

Canonical Outs New Ubuntu Kernel Update with Compiler-Based Retpoline Mitigation

Filed under
Ubuntu

New Linux kernel security updates have been released for Ubuntu 17.10 (Artful Aardvark), Ubuntu 16.04 LTS (Xenial Xerus), Ubuntu 14.04 LTS (Trusty Tahr), and Ubuntu 12.04 ESM (Extended Security Maintenance), adding the compiler-based retpoline kernel mitigation for the Spectre Variant 2 vulnerability on amd64 and i386 architectures.

Canonical fixed the Spectre Variant 2 security vulnerability last month on January 22, but only for 64-bit Ubuntu installations. This update apparently mitigates the issue for 32-bit installations too. Spectre is a nasty hardware bug in microprocessors that use branch prediction and speculative execution and it could allow unauthorized memory reads via side-channel attacks.
