As I reflect on my experience with Gentoo Linux, I have to admit that I've grown increasingly frustrated with the all-encompassing nature of systemd. What was once a convenient and manageable system management tool has morphed into an overbearing behemoth that insists on doing its own thing. I've struggled with the countless issues it's introduced, from resource limits being imposed without warning to logging inconsistencies that leave me questioning what's happening behind the scenes. And let's not forget the constant tweaking required just to keep up with its ever-changing configuration. The final straw came when I found myself wading through a sea of logs and configs to troubleshoot a seemingly trivial issue - only to discover that systemd was hiding the problem from me in the first place. It was a moment of clarity: I'd had enough. I've made the switch, abandoning systemd for a more straightforward alternative. And while it's been a learning curve, I'm eager to enjoy the peace and quiet that comes with system management without this behemoth breathing down my neck.

The blog post explains how to use public key authentication with PuTTY for secure login to a server over SSH. To start, a key pair must be generated using Puttygen, then the public key is saved on the server and the private key is configured in PuTTY. After setting up the key permissions, users can log in without entering their password. The post also includes a bonus tip for setting up an SSH tunnel to secure traffic between two machines.
