CentOS mentions (8)

  • SUSE working on a RHEL fork
    First, it is important to state that Stream is not a rolling release, at least not in the sense that you are thinking. It is "rolling" within a major release, but so are plenty of Linux Distributions. This is also why the centos.org website stopped using "rolling", and started using "continuos" instead at December 2020 (commit). So anyone that keeps using this wording is intentionally being misleading or... Source: 10 months ago
  • Keeping Open Source Open: Rocky Linux
    I get that Red Hat has shown themselves to be less than trust worthy given the sunset of CentOS 8, the removal of the centos.org repo updates and the characterization of anyone who uses their software via a clone distro as being a "freeloader" or "parasite". Source: 11 months ago
  • what is the typical size of Linux updates?
    This might be a good use case for RHEL family distribution (such as CentOS Stream or AlmaLinux) or Debian. These are much longer lived distributions, and provide fewer update churn over time than other distributions. Source: 11 months ago
  • How to learn Linux , what to learn in Linux , how to prove them i know linux?
    The easiest approach to this is to download CentOS 7 from centos.org. Source: almost 2 years ago
  • Wallpaper from CentOS
    I looked out for days now but didn’t find anything. I’m looking for the stock wallpaper from CentOS Stream. Like the background on their official website: Https://centos.org Does anybody have more luck or better sources than me? Thank you in advance. Source: about 2 years ago

OPNsense mentions (94)

  • How to bypass public IP and NAT
    Firmware's like Asuswrt-Merlin or OpenWRT can support dynamic-dns, or you can do like I do and run something like OPNsense in an x86 VM with a NIC passed through, or buy an inexpensive firewall appliance (up to 500mbps/1gbps/10gbps). Source: 5 months ago
  • Stop ISP from getting into my Router
    The easiest solution is to buy your own router, set it up, disable the router functionality on the Fritzbox 7590 and plug your router into it. It'll be cheaper and easier than a Cisco Firewall, but if you want to go the dedicated firewall route then I would recommenced OPNsense. Source: 5 months ago
  • OpenBSD Innovations
    BSDs may not have a significant presence on desktops, but they're well known in the networking world for their reliability. They also were the foundation used to build OSes for specific applications. OpnSense and XigmaNAS, for example, are two excellent FreeBSD based applications aimed at firewalling/security and NAS/services. https://opnsense.org/ https://xigmanas.com/xnaswp/. - Source: Hacker News / 10 months ago
  • Switches That You Actually Own
    For switches? OpenWrt supports a few models toward the lower end, and SONiC support a bunch at the higher-end datacenter ToR market, but none of these options are SME production-ready like Linux servers or OPNsense firewalls. Source: 11 months ago
  • Having to pay postage to ship back a DoA product sucks from a customer perspective
    That’s a stupid policy, and it looks like one of my UDMs is defective. I’m an idiot for not just buying good quality open boxes and putting https://opnsense.org/ on them. 🤦🏻‍♂️. Source: 11 months ago
