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'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.

My Internet provider just installed a 2,5/1Gbps Internet connection and I've asked the guys to run a couple of their fiber to connect my router (HP Prodesk with OPNsense) to my server. I didn't know that the fiber is single mode and all the SFP+ sold used now seems to be all for multi mode fiber (www.bargainhardware.co.ukfor example). The cable is about 30m, can I use a 810nm SFP+ or is it definitely better to use a 1310nm?

Hi everybody! For my OPNsense router (on a VM on Proxmox) I need a 2,5Gbe card (to connect to the ONT of my provider); I only have 2 PCIe 3.0 x1 or 1 x4 because the only x16 is for a dual SFP+ fiber card.

Can you suggest me a NIC (I'd prefer to buy used)? Is it better to go with a 2,5 or 10Gbe? The cooler (temperature!) the better. I just need 1 port, if there are 2 it would be better, but the most important thing is the low operating temperature.

Thanks!

I have installed Debian with software RAID1 (and installed Proxmox on it) on 2 256GB SSD and I now want to move to 2 500GB SSD, how do I proceed?

Edit: the RAID is of the OS disks.

Hi all, I have a Proxmox server hidden away where it annoys nobody, and a small PC I'm the TV cabinet that I need to turn On/OFF every time I use it and when a movie needs to be transcoded, the fan spins like crazy.

Have anybody tried to use a Windows VM and share the desktop with NDI? In this way I just need an NDI decoder behind the TV and all the job will be done by the server.

Any thoughts about this?

Edit: NDI: Network Device Interface: basically it's an audio/video (and intercom) transmission over IP with low latency. The sender could be an hardware encoder or a software.

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! 🤷🏻‍♂️
