  • FOSS Projects Live Off Community Support

    If there's a project you like you don't just have to be a developer to help support and help that project grow, there are plenty of other ways in which a regular person can help out a FOSS project.

  • Routing and Firewalling VLANS with FreeBSD

    When first experimenting, it is important to start with something simple. It can sometimes be far too easy to model very complex setups and then have to spend a lot of time debugging to understand what is not configured correctly.

    These example networks offer both an introduction on how to set up VNET jails with VLANs and show some of the power of their use. A production network built from this would want to give each jail its own file system, this step was skipped to make it easier to follow along.

    The BSD Router project has an example VLAN and VNET multi-tennant set up on their website that includes multiple different virtual machine frameworks. This example is well worth study and this article has hopefully provided the background to help you understand how this network is set up.

  • [Old] FreeBSD On A Raspberry Pi 4 With 4GB Of RAM

    This is the story of how I managed to get FreeBSD running on a Raspberry Pi 4 with 4GB of RAM, though I think the setup story is pretty similar for those with 2GB and 8GB.1

    I also managed to get Rust built from source, (kind of) which is nice because the default Rust installer doesn’t seem to work for FreeBSD running on a Raspberry Pi.

    If there’s anything awry with these steps, please contact me so I can fix it.

  • The Surprising Power of Business Experimentation

    We’ve long associated innovation breakthroughs with science and technology coming out of R&D labs, e.g., the transistor, penicillin, DNA sequencing, TCP/IP protocols, and so on. Such major lab-based breakthroughs are at one end of the innovation spectrum. At the other end are market-facing innovations, whose purpose is to create appealing and intuitive user experiences, new business models, and compelling market-based strategies.

    Lab-based innovations were generally born when scientists, mathematicians or engineers developed new theories, technologies, algorithms or programs in an R&D lab. Over time, often years, the innovations found their way to the marketplace. Since technology and markets advanced at a relatively slow pace, there was little pressure to reduce the transition times from lab to market. This was the prevailing innovation model through most of the 20th century.

    It all started to change in the 1980s as the rate and pace of technology advances significantly accelerated. The hand-offs and elapsed times to take an innovation from lab to market were no longer competitive, especially with products based on fast changing digital technologies. Start-up companies significantly shortened the time-to-market for new products and services, putting huge pressure on companies still operating under the old rules.

    These competitive pressures, were further exacerbated by the explosive growth of the Internet in the 1990s, as I personally learned when becoming general manager of the newly established IBM Internet Division in December of 1995. A lot was starting to happen around the Internet, but it was not clear where things were heading, and in particular what the implications would be to the world of business. With the Internet, there was no one technology or product you could work on in the labs that would make you a success in the marketplace. This time around, the strategy itself had to come from the marketplace, not the labs.

  • SeaMonkey on Pi4 no longer freezes

    Ans now SM is behaving nicely, no appreciable freezing. I am testing version 2.6.1, and playing around on youtube.com do get a segmentation fault sometimes. I can live with that, better than freezing. Running SM 2.53.5.1.

    One other thing: The SM cache is in /root/.mozilla, not happy with this, as always trying to reduce writes to the drive. So have changed it to /tmp. SM creates a folder named /tmp/Cache2. In EasyOS, /tmp is a tmpfs, in RAM. The downside of this is the cache will be lost at shutdown. Probably an upside is a possible security benefit.

  • 5 ways Red Hat Insights can improve your sysadmin Life

    The way we do things is changing fast. This has become a necessity as our systems get more complex, our workloads evolve, and our deployments rapidly grow in size. Thanks to the innovations brought about by openness and collaboration, we can develop tools and services to cope with these quickly evolving times. For us to reap the benefits of these advancements, we should open ourselves to carefully exploring how various tools suit our requirements and fit into or change our norms. By doing so, we may simplify a lot of our mundane tasks, reduce overhead, and address the major pain points in our operations. Having worked as a sysadmin in the past, I've discovered many automation tools and services that have made my life easier. One of the most recent is Red Hat Insights. In this article, I share five ways this service that is included with your Red Hat Enterprise Linux (RHEL) subscription can improve your life as an admin.

croc Is A Tool For Resumable, Encrypted File And Folder Transfers Between Computers (Command Line)

croc is a free and open source command line tool for secure file transfers between computers. It uses relay-assisted peer-to-peer transactions and end-to-end encryption via password-authenticated key exchange. The program is written in Go and is available for Microsoft Windows, macOS, Linux and *BSD. The idea behind croc is being able to transfer files and folders between cross-platform computers securely, fast and easy. With support for resumable, peer-to-peer transfers. As a bonus feature, croc is also able to securely transfer a short text or URL directly. The data transfer is done using a relay, either using raw TCP sockets or websockets. When the sender and the receiver are on the same LAN, croc uses a local relay, otherwise a public relay is used. Thanks to this, croc can send files between computers in the same LAN, or over the Internet, without having port-forwarding enabled. The data going through the relay is encrypted using a PAKE-generated session key. For this, croc uses code phrases, a combination of three random words. By default, a code phrase can only be used once between two parties, so an attacker would have a chance of less than 1 in 4 billion to guess the code phrase correctly to steal the data. Read more

Linux distributions: All the talent and hard work that goes into building a good one

I regularly read the Linux Mint Blog, not only because it is useful to keep up with what is happening with the Linux Mint distribution but also because it occasionally gives very interesting insights into the development and maintenance of a Linux distribution in general, and the Linux Mint distribution(s) in particular. To be honest, I was disappointed some years ago when Clem (Clement Lefebvre) discontinued his Segfault blog, because it always contained good technical information and interesting insights. Read more
