  • University of Toronto ☛ BSD PF versus Linux nftables for firewalls for us

    One of the reactions I saw to our move from OpenBSD to FreeBSD for firewalls was to wonder why we weren't moving all the way to nftables based Linux firewalls. It's true that this would reduce the number of different Unixes we have to operate and probably get us more or less state of the art 10G network performance. However, I have some negative views on the choice of PF versus nftables, both in our specific situation and in general.

    • Dan Langille ☛ Another pair of SATADOM devices

      Now that r730-01 is booting from SATADOM devices (which are directly attached to the M/B, thereby freeing up drives bays / PCIe slots for larger devices), I thought it wise to buy a second pair. For two reasons: The price of used devices was pretty good It’s good to have spares nearby In this post: FreeBSD 14.3 smartmontools-7.5 smartctl info Here is the SMART info.

    • Dan Langille ☛ Creating a new zpool for r730-01

      Finally, it’s time to put together a new zpool for r730-01 (the storage information at that URL is already out of date; once this new zpool is created, another post will replace it).

    • Dan Langille ☛ r730-01 zpools

      This post documents the drive locations for zpools within r730-01. It will be replaced from time to time with a new post. To the left of a device is an indication of the drive physical location.

  • Jeff Geerling ☛ Nvidia Graphics Cards work on Pi 5 and Rockchip

    I have a Raspberry Pi and an Nvidia graphics card—and I'm easily distracted. So I put down my testing of a GB10 system for a bit, and compiled mariobalanica's branch.
