I followed this tutorial to create local certificates for my home server, but now it failed to renew automatically and I have no clue waht to do. Can anybody assist me in debugging, please? https://notthebe.ee/blog/easy-ssl-in-homelab-dns01/

I'm using duckdns.org, added mydomain.duckdns.org and the local IP of my home server. In Nginx-Proxy-Manager I have created the respective wildcard certificate. The log of my NPM container reports the following:

I noticed my home servers SSD running out of space and it ended up being my Jellyfin Docker container which wasn't clearing the directory for transcodes in /var/lib/jellyfin/transcodes correctly.

I simply created a new directory on my media hard drive and bind mounted the above mentioned directory to it. Now Jellyfin got over 1 TB of free space to theoretically clutter. To prevent this I simply created a cronjob to delete old files in case Jellyfin isn't.

@daily /usr/bin/find /path/to/transcodes -mtime +1 -delete

Easy!

I got a bunch of self-hosted stuff and use a VPS that has a public IPv4 to access my services because my home network has only DS-Lite. My home server ist connected to the VPS using Wireguard.
Now I want to connect my Smartphone to my VPN to be able to access some local services remotely. I'm able to add a second peer to the Wireguard config on the VPS, but I'm struggeling to configure the AllowedIPs correctly.
The VPS apparently needs AllowedIPs 10.0.0.0/24 and 192.168.178.0/24, but the Smartphone as well for both to redirect request into my home network. But it's not possible to configure the same IP ranges for two peers. What do I do?

I'm running Jellyfin in Docker in my home server for movies and shows. I recently added a music directory and apparently after that I'm getting almost hourly notifications from my Uptime-Kuma instance connected to Gotify that Jellyfin is down with status code 502. It's quickly up again, but I'm wondering what's causing this.
I have Nginx Proxy Manager configured for a local and a public domain pointing to my Jellyfin instance.
Any idea what could be causing this?

I just discovered the Sota Remix of Bring Me The Horizon's "Can You Feel My Heart" and feel like I've heard it in someone's set, but I don't know who's. I listened to a lot of Nitepunk, Imanu, Buunshin, DJ Ride, Gladde Paaling and Luude lately. Maybe someone recognizes it.
Here's the track: https://www.youtube.com/watch?v=6SRzEgCY0Xs

I have an Intel Core i5-7600K and just passed through my Intel HD 630 iGPU from my Proxmox host to a virtual machine running Debian to be able to use it in a Jellyfin Docker container. Everything worked fine, but I used only the basic configuration that I found which I don't really get. Can someone explain to me whether I'm missing something?

First I followed this tutorial: https://3os.org/infrastructure/proxmox/gpu-passthrough/igpu-passthrough-to-vm/
But I only added intel_iommu=on iommu=pt to my boot parameters and vfio, vfio_iommu_type1, vfio_pci, vfio_virqfd to /etc/modules.

But what are all the other parameters good for?
pcie_acs_override=downstream,multifunction initcall_blacklist=sysfb_init video=simplefb:off video=vesafb:off video=efifb:off video=vesa:off disable_vga=1 vfio_iommu_type1.allow_unsafe_interrupts=1 kvm.ignore_msrs=1 modprobe.blacklist=radeon,nouveau,nvidia,nvidiafb,nvidia-gpu,snd_hda_intel,snd_hda_codec_hdmi,i915"

Then I added the iGPU as a PCIe device to my VM using the Proxmox webUI and added the render device /dev/dri/renderD128 to the Jellyfin Docker container.
I followed the official instructions from Jellyfin: https://jellyfin.org/docs/general/administration/hardware-acceleration/intel/#configure-with-linux-virtualization

But I haven't added the host group ID, what is that good for?
And I also installed the intel-media-va-driver, i965-va-driver and firmware-linux-nonfree as well as firmware-misc-nonfree. Are all of those necessary?
And then I had to add options i915 enable_guc=2 to /etc/modprobe.d/i915.conf to get it to work. This is supposedly only necessary for Low-Power Encoding, but it was necessary to get hardware transcoding to work at all?

I'm happy that it is working now, but I don't really feel like I fully understood what I did. Were some steps unnecessary or did I miss anything?

I followed this guide: https://notthebe.ee/blog/easy-ssl-in-homelab-dns01/

But my Nginx Proxy Manager is running on a VPS that is connected to my local network through a WireGuard tunnel. Could that be an issue? I don't know why it's not working?

My NPM is also accessible to the local IP of my homeserver on which WireGuard is running.

I want to start Konsole in Split View which is possible using the --layout command but then also run a command like htop in one of the sessions. How do I do that?

I played a dozen or so matches in CS2 and sometimes enemies had a Premier rank of around 2500-4000 but according to Leetify the were Global Elite in CS:GO matchmaking!I'm Gold Nova 2 in CS:GO so naturally I get stomped by those players. What are your experiences? Is the rank not representative yet?

I'm currently using BackInTime and TimeShift to create local backups of my system and personal data. I configured both to keep 7 daily, 4 weekly and 6 monthly backups. I use this setup on my Desktop-PC as well as on my laptop.
Now I also use BorgBackup to create an additional backup of my local backups and right now use the same retention policy, so keeping 7 daily, 4 weekly, 6 monthly and 1 yearly backup.
This turned out to be a lot of data and my 1 TB off-site storage solution is currently using 953 GB of storage.
Now I was wondering if my double retention policy is even making sense and what others are using. So how long do you usually keep backups? How many backups do you keep and what would you suggest for my setup?
