I'm in love!

Hey all, So I want to upgrade my mini-PC based homeserver, which is slowly dying to a NAS/homeserver. Right now it hosts a Homeassitant istance and some photos.

Initially I wanted to use the jonsbo N4 case, because it has the perfect size and i could use cheap uATX boards. But others reported bad cooling with this case. So two Options: Jonsbo N3 - limited to mini ITX Jonsbo N5 - rather big and a bit more expensive

So what's your opinion on this ? Thanks !

Last week my trusty UniFi US-8-150W caught some stray something from a lightning strike in our backyard. I'm keeping it around to see if I can fix it, but we work from home here so I'm using this as an excuse for some new gear.

APs are UniFi and I'm happy with the management for those (UniFi Network in a container) but am considering Mikrotik options for switching.

I'd like 14+ total ports with at least some 2.5 GbE. I need 6+ PoE+ ports with at least 60 W total (normal load is around 56 W). I'm looking at:

• UniFi option
  • UniFi Flex 2.5G PoE
  • UniFi AC Adapter 210W (seemingly always out of stock)
  • UniFi Lite 8 PoE
• Mikrotik option
  • CRS310-8G+2S+IN
  • RB5009UPr+S+IN (could replace the EdgeRouter X as well)

Both options have some compromises and some overkill, which is part of the reason I think I must be missing some better option. Also, space is a consideration. I'd like to stick with 10"-ish format so I don't have to completely rework my physical setup.

(Also, hi! New to Lemmy but not the fediverse in general.)

Hey All,

I bought a Startech server rack that has a top punchout panel for cable management. Unfortunately it's just raw metal around the edges and I don't want to damage the cables I pull through there so I was looking for a brush grommel like the one I have linked in this post. The one I found isn't for the rack I have but it's an example of what I'm looking for. I've seen a lot of horizontal, 1U panels to put in but I'm specifically looking for something to go around an already existing hole, vertically, in the top of the rack.

Does anyone know of any universal kits I could get? Something I could cut to length?

Or do you have different solutions for how you protect your cables like I need? I was thinking a real hack solution could be to just wrap some dead cable in electrical tape and tape it around the edge of the punchout hole but I wanted to see if there was a more official grommel solution of some kind.

Thanks!

What would be good specs for small but power-efficient NAS. I want it to be budget friendly, I would probably look for 2nd hand stuff. I plan to use it for media storage (most likely immich) and the arr stack + jellyfin.

Give me suggestions

I have had Proxmox running nightly backups and saving them to my NAS for years now without any issues. I've been thinking that it would also be nice to have these copied over to my cloud storage (some smaller company, no available plugins).

I know Proxmox Backup Server exists, but not much more than that other than it can backup to popular cloud providers.

The cloud provider I have has a Linux client that will create a shared folder on the system. My thought was to mount the Proxmox VM backup location with CIFS, install my cloud client and then write a script to run as a cronjob that would copy files from the Proxmox VM to the cloud folder each night.

This feels a bit clunky so I just wanted to ask if anyone knew of a better solution.

I was poking around for a USB C 5G/LTE modem that I can run either off my laptop or plug into my router as a secondary WAN. Has anyone messed with something like this?

The secondary WAN is common, but I usually need some sort of DC power input instead of a single USB C cable that I can put into my laptop.

Hey all,

I have some questions and this community has been great with my other ones, I'm hoping you can help me out with these too.

This is the diagram of how I think I want my physical network laid out.

Hardware:

The patch panel has LAN cables I installed in the walls on ports 1-20. The ISP feed comes into the patch panel on port 21.

I was looking at getting a Cisco CBS-220 but I found out that those are EOS/EOL and the Catalyst 1200/1300 replaces them. Also that the C1200/1300's aren't actual Catalyst switches but that's beside the point. I couldn't find exact stencils for the C1300 but just know the Catalyst in the picture is supposed to be a 48 port C1300 with 10G SFP+ ports on the right side.

The Netgate is an 8200. According to Netgate's specs, the 8200 LAN ports operate at 2.5G and if I wanted faster, I'd have to upgrade to the 8300 plus some expansion cards. No need for that.

Questions:

1. Does this diagram make sense? I want everything in my LAN to be protected and controlled by the Netgate. By connecting the switch to the LAN port of the Netgate and then the WAN of the Netgate to the internet feed, I feel like that accomplishes that goal.

2. Can the C1300 be connected like this? I would need to get a 10G SFP+ for ethernet, not fibre, which I haven't looked for yet. I know with fiber you have to be careful to match both sides of the connection with the same speed otherwise they won't work. Does the same hold true for ethernet SFP's? Meaning, if I find a 10G ethernet SFP+ (since that's what the Catalyst port is rated for) and plug it into a cable going to the 2.5G LAN port on the Netgate, will they communicate properly?

Linux systems unable to reach out to internet behind pfsense while Windows work fine.

I am trying to set up my #homelab for #forensics and I have encountered a very weird issue. I am running an internal pfsense #firewall for my environment. On this firewall there are 3 interfaces: WAN and two Isolated Labs.

On the "WAN" interface, both #linux and windows systems are able to access the internet without any problems.

But on the other two lans - named Infrastructure and Lab - the Linux systems are not able to connect to the internet after booting, while the systems are able to communicate with each other. In order to get them working I need to go the respective interface and make any change there and save the page, practically refreshing the settings on the interface. After this all currently online linux systems on that interface are working as expected and connectivity is restored. As you can imagine this is a huge pain, especially when I am testing things and I need to turn on various systems at different times. If i put the systems on the WAN interface they face no issue at all, so what could be the solution here for fixing connectivity for linux systems on the other interfaces?

edit: it issue is both on pfsense 2.7.2 and 2.8.0

Hey all,

Building out my lab, I was going to get a rackmount UPS. The one I'm looking at is a Cyberpower OR1500LCDRM1U. It says it offers:

1500 VA, 900 W, 120 V

Do I understand correctly that all I need to do is find the Wattage rating for each of the components I want to plug in and add them up? My components right now are pretty light, only about 120 watts total. But soon I'm going to expand and build out a Nutanix CE cluster with 3 nodes and a rack of drives. I was looking at using some NUCs but they are each rated at 330W.

So that would mean even the NUCs by themselves would over-provision the UPS right? Then on top of that I would still need all the other equipment in the rack to be powered.

Am I understanding this correctly or is there something I'm missing?

I have an R320 that has 4 SAS drives 10TB each, which holds a lot of my data + backups from other systems, I also have an R710 which runs a lot of heavy workloads for my homelab, now I have to move to the other side of the EU and I don't know what to do with that lab, the electricy cost on the new country will be around 0.33c per Kw, while now I was paying under .10c.

Here are the options that I have considered

Take R320 with me As the SAS drives are in a unique configuration in xcp-ng it would be the safest option to transport the drives in a secure case with me and have the R320 moved to the new country, where I will set it up again and have some of my VMs and data.

Make current pc the new server I have a quite powerful and recent pc build from 4 years ago, I was thinking of buying SAS pcie interfaces for my PC so I can cinvert it to a server and be able to read the SAS drives, but this is a bit expensive and requires me to buy a new computer for my self.

Also, as I won't be keeping the R710, I was thinking of buying a few lenevo sff mini PCs and setting up a low power virtualization cluster and using the R320 or my PC as the storage medium.

I have also backed up everything to storj and the most important data are also synced to a few cloud storage providers for safe keeping.

How would you handle something like that? Would you start from scratch or try to bring as much as you can? I plan to invest at max 1k in rebuilding if needed but I would like to avoid it if possible, the SAS drives are enterprise grade and bought just a year ago so I would like to keep using them.

Hey everyone,

I'm back with another question. I'm looking at switches and have it narrowed down to two options:

Cisco Catalyst 1200-24T-4X

Cisco Business CBS220-24T-4X

I'm going to have a Netgate as my main router in the house but I am also going to have a dev environment that I don't necessarily want interacting with my regular network. Originally I was thinking of just getting an unmanaged switch but I might like having some light VLAN capabilities of a managed switch that I can have the option of using.

I don't have any use right now for PoE devices so I don't need the switch to do that. I'm having a hard time figuring out exactly what the differences are between the CBS model and the Catalyst model.

It's a difference of about $45. As far as I can tell, the main benefit to the Catalyst is Cisco's Cloud dashboard. I don't need or want that. I'll handle everything through a VPN connection back to the house and honestly, I don't see myself needing to interface with the switch much after I get it set up. If the cloud dashboard is the only difference then I'll just save the $45 and get the CBS model.

But I wanted to ask you all if there's something else I'm missing that might make the Catalyst a better choice?

Thanks!--

Hey all,

I'm looking to build a small half rack server set in my house and was wondering if there were any tools that let me build out a solution? I'm worried I'm going to forget something and just wanted it all listed out as I think of things.

Yeah I can probably build it out and keep track of it in Obsidian or Excel or something, I was just curious if there were server builder tools like there are PC builder tools?

I mainly want to make sure I get a rack big enough for the few pieces I want to put in it as well as I want to try to calculate the power draw and BTU output which I imagine will be pretty minimal. I just would like hard numbers to know for sure.

Thanks!

Been planning to migrate from my Supermicro monolith server for a while and finally finished the migration. Red thing is opnsense on an APU engine, Lenovos run a proxmox cluster, below is a mini PC with attached JBOD running TrueNAS.

Next step is to get another shelf for my Raspi and openDTU.

I am currently running a FreeBSD system on an old Dell Optiplex 790 (i3 2100) that has been upgraded a bit.

It has 16G of ram, and 5 hard drives: 1TiB SATA SSD, where the OS itself is installed, using UFS+/FFS filesystem.

The other 4 are 3TiB SAS drives, connected to an LSI 9300 HBA, and are in a ZFS raidz1 configuration.

I would prefer to stick with FreeBSD, but would also consider TrueNAS Core (also FreeBSD based).

Here's the problem. The 5 hard drives don't quite fit into the case. The side panel won't close completely due to the SAS connectors being slightly larger than the original SATA connectors the case was designed for.

My budget is sub $300.

I've seen a few 2U and 4U servers on eBay that seem to fit the bill. My concern is that energy usage would be significantly higher than it is now.

Any suggestions for alternative ideas that keep my existing storage would be much appreciated.

A recent storm damaged the siding of my house so I'll have to have it replaced. The thought occurred to me to run some network cabling behind the new siding (and likely new insulation) while its all pulled off. Should I run standard riser cabling or outdoor-rated cabling if I do so?

Obviously the most ideal solution is standard in-wall but I don't have the appetite for such a project given half the house was built in the 19th century and I know such an undertaking would involve quite a few surprises that I almost definitely lack the know-how to handle, and I'll probably be moving in a couple of years so I don't want to invest too much time or money into the endeavor.

Alternatively is there a good type of conduit I could run instead?

I’m looking to switch. I like to tinker and try new things.

Replies I’d like to see:

Tell me what OS you’re using! What do you like about it? What don’t you like? What is your primary use for it?

I don’t just want recommendations for my use cases, though I’ll list it below. I want to learn what’s out there and what’s possible.

My Use Cases:

I’m currently using QTS that was preloaded on a QNAP NAS that I got used.

My main goal is to do more self-hosting. I want to be as independent and self-sustainable as possible. Like many of us, I’m burnt out on being treated as a product by big tech.

I’d also like to try to set up a game server for my Steam library.

Really, I just like to tinker. I like when things break or don’t go according to plan. I like to research a problem and fix it!

So I need help with a split dns approach, or a direct fix, normally when running my tunnel on the simplest configuration I get this error:

Couldn't resolve SRV record &{region1.v2.argotunnel.com. 7844 1 1}: lookup region1.v2.argotunnel.com. on 10.43.0.10:53: read udp 172.16.91.156:54443->10.43.0.10:53: i/o timeout

When I tried to change the nameserver to cloudflare to make it accessible I get this error:

Anyone know why cf tunnels is asking the wrong DNS server? I know i specified 1.1.1.1 but it should have also asked kubedns as I specified its ip I do have to specify its nameserver or else it does not work, it wont be able to connect to their argotunnel domain without going through 1.1.1.1

kube-dns   ClusterIP   10.43.0.10   <none>        53/UDP,53/TCP,9153/TCP   12d

also its the correct ip I would like it, if you cant give direct advice, to try this deployment, and add a custom dns server that idk, configures it so that correct ip queries goes to 1.1.1.1 and the rest kubedns, i dried coredns, and other dns servers and I couldnt get anything to work I am trying the nameserver 1.1.1.1 because otherwise I get the error mentioned above. and no, I am not running a firewall nor anything that should block it outside of k8s, as it runs perfectly fine on the host.

So I have a issue. whenever I accessed all of my services via 192.168.1.22/wordpress for example. it forwarded that /wordpress to the actual wordpress domain, leading to page not found, however when i strip the initial proefix, i can access the base page, however, when lets say wordpress wants any css or assets, it will look at 192.168.1.22/assets which wont work, so basically, I need a way for sort of, emulate the url paths, so it wont take actual queries to places that dont exist and tries to access resources the incorrect way, i know siteURL exists for WP, but i want a catchall solution which helps my other services.

As the title says I’m curious what quality people choose. I chose Ultra-HD and am a little stunned when I look at the file sizes for some movies at 100GB.

Another question is how can I change the quality and will Radarr remove the existing download and then get a smaller one?

If it helps I have a GPU capable of hardware transcoding.

When combined with today’s other vulnerabilities, CVE-2025-1974 means that anything on the Pod network has a good chance of taking over your Kubernetes cluster, with no credentials or administrative access required.

I got a server recently and now I need storage and I’m a little upset seeing the prices of HDDs.

My aim is for 4x10TB to run on RAID 5.

I saw other people linking serverpartdeals and they do ship to the uk but the shipping is insane particularly as I want to buy them one at a time to spread the cost.

So what would you guys suggest? New ones are hella expensive, but I can’t seem to find any decent places selling manufacturer recertified ones.

Hey community! Do you use any database or anything to manage your environments? I started a relational Notion database a while back but never dug in. Objects types for things like hardware, software, deployments, technologies, and tie-ins to my other LifeOs databases. (e.g., the inkbird aquarium thermostat in Smart Life/Tuya via Home Assistant is linked to my aquarium database as a gear object.)

I'm rebuilding half my lab right now and thought it might be worth seeing if there's a better method before returning to my half-assed system.

(I pay for Notion - I also failed at making my super complex Obsidian implementation work across my devices and platforms. I'm in the market for a replacement for that whole universe, so if this thread turns into a moratorium on Notion, I get it. Still, I'm open to discussion, so snark is unnecessary.)
