I’ve noticed that my Intel Xeon E3-1230 v2 CPU runs at the maximum frequency on my TrueNAS Core, even at a negligible load. This post describes how to configure the
powerddaemon to shave off a few watts of idle power by allowing the frequencies to scale. -
Cloudflare Zero Trust tunnel client does not support FreeBSD out of the box, and Cloudflare does not provide FreeBSD binaries either. This means that we need to either fetch the package or build the binary ourselves, and then configure tunnel in a roundabout way: automatic tunnel setup does not work. Lastly, we want to enable it in a way to survive the TrueNAS OS upgrades, let alone reboots.

These are my notes about configuring services with Podman on RHEL and related OSes with SELinux enabled, using compute instance in the Oracle Cloud with Oracle Linux 8. Information presented below is readily available elsewhere – see references – however, the intent of this opus is to condense all of that into palatable chunks to serve as a somewhat quick answer to the question “How do I get this container running on my instance?” without needing to spend hours reading pages and pages of documentation.

This is a short description of how to host services, using STORJ node as an example, on a host behind CG-NAT, or otherwise restrictive firewall, by forwarding packets through WireGuard endpoint on a relatively fast nearby VPS. This is not specific to Storj, and can be adopted to hosting other services.

One can connect to the Xfinity modem configured in bridge mode directly with a cable as described in the support article or configure static route on the third party gateway and avoid running around with cables. This post is a confirmation that this approach works. -

How to add Self-Signed CA and Server SSL certificate to Synology DSM and configure it to be used with services. Two poorly documented pitfalls I stumbled upon. -
Could not find the guide that worked. Had to figure stuff out on my own. -
This is a somewhat tutorial-ish guide about creating a self-signed Certificate Authority suitable for issuing SSL certificates to be used for various servers, services, and devices to ensure "green lock" in the browsers and happy users using macOS GUI tools. -
Ever wanted to have an always-on VPN on an iOS device? IKEv2 is the answer; unfortunately, it is not properly supported by any appliances commonly laying around the house - so we'll improvise. This post is about the setup and configuration of an IKEv2 VPN server based on Strongswan running inside of the Alpine Linux instance in the virtual machine hosted on Synology Diskstation. Pitfalls and challenges making split-tunnel work seamlessly. And don't have your hopes up too high -- while both full tunnel and split tunnel work just fine on a routing level it is not currently possible to make split-DNS work seamlessly enough, without client-side configuration. See closing notes for details. You might as well jump to the OpenVPN article if that is important. -

It shall not be longer than 64 characters. The UI will accept longer string, however, doing so will result in failures setting up the tunnel. -
I have a fairly old but great laser multifunction Canon MF4150 that never really supported scanning from anything but windows and whose macOS printing drivers lag behind OS releases by a large margin, causing frustration after each new release. Still, it has been over 10 years, and it works great, and I’m absolutely happy with its performance.

What do you do when your favorite backup provider decides to focus on corporate customers and discontinues the home edition of its cloud backup software? You start testing replacements and soon come with an alternative that in retrospect happens to be more robust, flexible, and resilient. This post will provide supplemental information for setting up unattended periodic Duplicacy backup on a macOS. The main goal is to provide meaningful configuration files to save time re-inventing the wheel.
