Hi community!
I'm in the process of building a new office PC for:

• tenths of firefox tabs open some with Microsoft 365 Excel
• some VMs because I will be installing Debian on the host, but in the office we use some Microsoft software and because, since I install, uninstall, create a lot of mess, I like to be able to go back to old snapshots or format and reinstall Windows without impacting my day to day job.

I'm still undecided about the CPU: AMD 9950x, 9700x or 7950x, but where I' completely blind is the motherboard. What I would like:

• more than 2 PCIe slots to:
  • install a PCI USB card to pass the whole controller to a VM
  • install an extra NIC
  • I want to be able to install a graphic card in future if needed
• more than 4 USB-A ports
• more than 1 USB-C port
• a well known and reliable brand

Do you have any suggestion even for an SSD (probably 4TB, in the 2-300€ range, maybe even something more) and RAM (64GB)?

Thanks!

I want to switch from Windows to Linux for my office PC.
I will be using multiple Windows VM because in the office we use multiple software that runs only on Windows (maybe we'll switch to something else, but right now I need the VMs) and because i like to snapshots and go back in time when I test new software.
I thought about Ubuntu because it seems to be the most user friendly.
I always work with a tons of opened windows (mainly Firefox) and I like to have a place for each of them, Right now on Windows I use DisplayFusion that creates multiple virtual screens (7, 4 or the 32" horizontal monitor and 3 on the 28" vertical one, both 4K), I've attached the configuration.
So, the question: is there a software that works kinda like DisplayFusion? (virtual screen each with it's own taskbar, maximize in each of them, remember the position of each window, ...).

P.s. Can I pass only some USB port to a Windows VM using KVM?
Pp.s. Is it possible to use Premiere on a Windows VM? Would it run smooth?

When I go on vacation I prefer to keep my smartphone with WiFi and mobile data off, but I really don't like the way Spotify handle offline content. Most of the time it doesn't download everything and when I do a research, it show me even content that's not available offline (how can it do that?). Is there a selfhosted service that I can use to download my playlists and play them with an Android app that can download them?

I'd like to use my smartphone WiFi SSID to determine if I'm home or not. When I'm home the alarm (kinda, just notifications from some sensors) needs to be shut off and a light needs to be turned on. Since the sensors update can be forced at maximum 1 minute (but I'd prefer to leave it at 15 minutes to preserve battery) and since 1 minute is too much, is there a way to send an intent to HA companion app to send a sensors update? I would use Tasker to send the intent.

I've a VLAN dedicated to IoT devices and, of course, HA can't discover them. Is it possible have them discovered by HA via MQTT? Create them manually it's a pita because they're a lot and I would have to create sensors/switches + battery level + RSSI Thanks!

I've finally been connected to a fiber connection 2,5/1Gbps! 🥳 Now I want to share my connection with my neighbor and so I've installed 3 PCIx dual 1GB nic (I'm out of PCIe slots 🤷‍♂️).

The connections comes from my OPNsense to the server (Proxmox) via a 10Gbps fiber connection.

I want OPNsense to take car of firewalling dividing the neighbor networks with VLANs. The OPNsense part is done and working, I need to assign to each of the 6 1Gbps NIC each VLAN.

I've tagged the traffic going into the server via the fiber connection, but now how can I assign each VLAN to each NIC? Thanks!

Edit: Proxmox has nothing to do in the equation, it just happens to be on the same server where the NICs are.

I have only a PCIe 2.0 x4 and a PCIe 3.0 x16 free and I need to install a 10Gbps SFP+ card and a graphic card for transcoding with Jellyfin (the CPU is an old E5-2620 v2). Since I can't find any SFP+ card that is x4, do you know a graphic card with decent transcoding capabilities (I'd day 2 4K simultaneously) that is only PCIe 2.0 x4?

Edit: the x4 slot is full length.

Hi all! Do you know a valid app for GutHub? I've searched on F-Droid, but they are all abandoned. Thanks!

I've found these NetApp SAS Festplatte 6TB 7,2k SAS 12G 3,5" - 111-02374 E-X4064A-R6 ST6000NM0034, that cost only 38€! It's a brand that I've never heard about and I've no idea how many hours they've worked (I've asked and I'm waiting for an answer). What do you think?

Edit: I've asked the seller if there is a custom firmware that makes the drive unusable and it answered me saying that they work with any SAS HBA controller. They have worked 1863h and written 130TB (he showed me 4 screenshots of 4 tests of 4 drives)

Hi all, I've bought 2 Dell H310 6gbps SAS HBA controlelr with cables, but the cables have the wrong connectors (for me). They have this:

While my drives have this one:

What's the name of those 2 so that I can sell mine and buy new ones? ...or should I just cut the side of these and power supply connectors? 🤔

Hi all, I don't know if this is the right place to post this...let me know :)

I'm trying to create a NFS share, this is my /etc/exports:

/mnt/pool/var_VM_docker/ 172.31.0.0/24(rw,sync,no_subtree_check)

When I try to connect with:

sudo mount -t nfs -o nfsvers=3 -vvvv 172.31.0.1:/mnt/pool/var_VM_docker /mnt/test

I get:

mount.nfs: timeout set for Mon Apr 15 19:07:11 2024
mount.nfs: trying text-based options 'nfsvers=3,addr=172.31.0.1'

I don't have iptables enabled, nor SELinux. I've tried exporting it on 127.0.0.1 and connecting it to 127.0.0.1, but the problem persist. What am I doing wrong?

Fellow selfhoster, do you encrypt your drives where you put data to avoid privacy problems in case of theft? If yes, how? How much does that impact performances? I selfhost (amongst other services) NextCloud where I keep my pictures, medical staff, ...in short, private stuff and I know that it's pretty difficult that a thief would steal my server, buuut, you never know! 🤷🏻‍♂️
