  • Leopard Flower firewall – Protect your bytes

    Several months ago, I decided to explore a somewhat obscure topic of outbound per-application firewall control in Linux. A concept that Windows users are well familiar with, it’s been around for ages, providing Windows folks with a heightened sense of – if not practical factual – protection against rogues residing in their system and trying to phone home.

    In Linux, things are a little different, but with the growing flux of Windows converts arriving at the sandy shores of open-source, the notion of need for outbound control of applications has also risen, giving birth to software designed to allay fears if not resolve problems. My first attempt to play with Leopard Flower and Douane was somewhat frustrating. Now, I’m going to revisit the test, focusing only on the former.

    [...]

    Leopard Flower firewall is an interesting concept. Misplaced, though, for most parts. It caters to a Windows need that does not exist on Linux, and to be frank, has no place in the Microsoft world either. Then, it also tries to resolve a problem of control and knowledge by requiring the user to exercise the necessary control and knowledge. But if they had those to begin with, they wouldn’t need to dabble in per-application firewalls. Furthermore, the software is still fairly immature. There are at least half a dozen little things and changes that can be implemented to make lpfw more elegant, starting with installation and followed by service and GUI model, prompts, robustness, and a few others.

Post/Node #111111

This is the 111111th node. It's a special number and a milestone for us. Will we have reached the 222222nd by 2030? Time will tell. Maybe Drupal won't even be around by then.

Ubuntu: Didier Roche's Interviews Series and Resurgence of Ubuntu Touch

  • Welcome To The (Ubuntu) Bionic Age: Behind communitheme: interviewing Aaron
    I’m Aaron Papin and I’m from Trinidad and Tobago. I work at an IT consultancy that specializes in open-source solutions for SMBs. I’m a technician, but I also work in designing and deploying websites and even on ads from time to time. It’s pretty freeform and fun. I knew of Linux for years, but I only dove in after a hard drive failure a couple years ago. Because why not at that point? It didn’t take me long to start using it mostly full time (games). Even though I’ve worked on my own themes in the past, I’m still pretty new to the Linux community. Hobby-wise, I really like TV, cooking, video games and keeping fit when I’m not on an “extended break”.
