Hi everybody I own a HP DL380 g7 which works fine. Today I added a p822 controller for my d2700 storageworks. But when a attache the d2700 the controller doesn't initialize anymore. If I start the server and attache the d2700 sas cables when it's started it finds the d2700 and I can see the disks. Obviously I can't use it this way because when i reboot I need to unplug and plug the sas cables again. Not really allot of information to find online. Except for firmware update. Anybody have any experience with firmware updates in proxmox for HP servers gen7 ? Thanks for any advice.

Hey All,

Having a bit of trouble with my network setup. I'm mostly a noob with very light understanding of what I'm working with, so bear with me.

I've got my opnsense box setup with mostly defaults set for rules. The opnsense box is hooked directly to an MB8611 modem on the WAN interface, with LAN interface running to an 8 port managed netgear switch on port 1 of the switch. I have port 2 of the switch hooked up to a vlan-aware access point. Other ports are occupied by physical links to some servers.

Everything on LAN works fine, including the access point. I have the access point setup with 3 SSIDs, all that can connect clients no problem. Some of the clients on the network are game consoles/gaming PCs that run into connectivity issues with some titles, I believe because of a strict NAT. Rather than just assigning outbound rules by static addresses, I opted to create a VLAN to house all gaming devices and segment them from the network. I don't need them to talk to each other or other devices.

I have created VLAN10, assigned it a gateway address of 192.168.10.0/24, setup DHCP and assigned the LAN as the parent interface. I created a new SSID on the access point and gave it the VLAN 10 tag. All of the ports on the switch are now assigned to default vlan1 with untagged traffic, and then ports 1 and 2 are assigned to vlan 10 with tagged traffic. Testing with an iPhone, this works totally fine. I get assigned the correct leases and can make outbound connections to the internet. Testing on a windows 11 gaming PC, previously connected to an untagged SSID and now switched over to the tagged SSID, I am unable to make outbound connections to the internet. Another android device that I connected with to the new SSID also worked fine, so I'm not sure what's up with this PC. I haven't tested other gaming devices yet.

Any ideas on what I'm doing wrong here?

Not that this hasn't been asked before, but what are your favorite NAS cases on 2023?

I started with an old antec p180 case back 20 years ago.

Currently using a rosewell rsv-l4500 4u.

Really wish I could get my hands on a 45drivres style case like the q30 or something - just without the insane price tag. 😂

Does lemmy have an even remotely thriving version of r/homelabsales?

I don't want to break my anti-reddit oath since June but this might do it.

Today’s the day Jeff Geerling makes it to the Washington Post for a decent story about carrier pigeons vs. Ethernet. Very fun to see as both a homelabber and newspaper person.

Hi all,

I thought it would be as simple as flicking a switch to change from router to bridge mode and plug in my own router, and that couldn't have been further from the truth :(

My ISP provides a huawei hg8145v5. I ordered a static IP from them as well. They gave me full access to the router to be able to put it in bridge mode. The router I'd like to handle all actual routing is an asus zenwifi xd8.

The setup I'm going for is ISP ONT/Router > Asus Zenwifi XD6 -> TrendNet 10g unmanaged switch -> NAS, PC, server

So in the isp router, I set it to bridge mode and connected it to the wan port of the asus router, then connected LAN 1 of the asus router to my 10g switch. basically just inserting the asus router in the chain that had been working before.

I had no internet at all. Strangely, the asus reports that the internet is connected, but the speed test on the qos section cannot connect whatsoever.

I thought it might have something to do with the static IP, so I tried setting the static IP assigned to me to the WAN IP, used the same subnet mask the isp router had assigned, and set the isp router as the gateway. Same exact thing. Basically everything I tried resulted in either a "connected" status yet no internet, or a "disconnected" status.

I'd really appreciate some help. I really though I'd just change the isp router to bridge mode and I'd be smooth sailing but I've basically blown up my network. Also for some reason, the windows network tab is not finding my NAS anymore. I can only connect by typing its local ip or mapping a drive, but I used to be able to go to the network in window explorer and my nas would show up there and I could just access everything I wanted that way. anyway, I'd appreciate any help. i've been at this for literally the entire day and am only now reaching out for help. Thanks!

I've installed OpenWRT on an Edge router (ERX) and its made me want to custom firmware every piece of networking equipment I own.

I've got an ER4, AP Pro and PlusNet (BT) router lined up but I wondered if it's possible to do anything with the Unifi switch I have? I know there's OpenWRT images for the ToughSwitch line by Ubiquiti but looking at the OpenWRT forums it looks like the Unifi switches are a dead-end.

I've got a craving to hack/customise it but can't find any options.

I am still very much a novice in the self-hosting space, Linux etc. having fairly recently switched from using macOS as my daily driver and not tinkering much at all.

One of the things that often confuses me is networking and making sure my setup is secure. This is currently holding me back from hosting more stuff locally that I would require access to from outside my home, as I am afraid I am doing something that could severely compromise my data. It can sometimes be difficult to follow explanations from more advanced users due to the many different components of networking and security, and different layers of abstraction, which prevents me from following completely. I might understand one particular case, but then be unable to make connections to another one. So I would want to research this more intensively, and ideally I would end up being able to easily understand the data flows - the paths the data takes (e.g. I make a HTTPS request to some server from my laptop, how is that traffic routed correctly through my local area network and later the wide area network), in what forms (i.e. different protocols, encryption layers etc.).

In communities like this, I see there are a lot of very knowledgeable people who maybe could recommended any resources that cover this from the basics and onto more advanced stuff? Maybe a textbook from a university course on ICT that is considered particularly good? A YouTube channel with great explanations and visualizations? I am looking both at home LAN and internet in general. Enterprise level networks are not very interesting to me (at the moment).

Hi everyone! I have a couple of old desktops as servers in my rack. Sometimes , very rarely, I need to use the machines console.

Slide-out rack monitors are incredibly expensive here in Germany, so these are not an option. Next I thought about USB monitors - don these work out of the box with Linux or do the need special drivers? Or would I be better off using KVM over IP? Do you know of other not-so-expensive solutions?

I am currently looking into upgrading storage for my homelab. The two routes I am looking at are grabbing a dell r730 or a disk array. They are both about the same price, but my major purchase concern is heat and noise. My office/homelab is in a 10x10 foot room. I have worked hard to get the sound floor at my desk to be around 44dB, and the temps to top off at 79f, 74 on a good day with the door open. Is a disk array going to add more heat and noise to the room than a dell r730 server running proxmox with trunas?

Hi there peeps,

Currently got an old B250M Performance motherboard, although it does the job im looking to upgrade to something that is AM4 compatible, already bought a wraith stealth cpu cooler for dead cheap second hand.

I'm changing from Debian to Unraid too, mainly using the server as media server, but hosting some other apps too. Only got one ssd, the rest are hdds, so multiple ssd slots are not much of interest for now at least.

Is there anything I should be looking for in a motherboard whilst browsing? Anything that would make it more future proof etc? I don't really know a whole lot about Motherboards.

Appreciate any tips 😇

I have a home network consisting of several raspberry pis, a Roku, and a total of 4 laptops and smartphones.

Currently, I have the ISP provided router/modem in bridge mode which I'll refer to as my modem. This is connected to my own ASUS wireless router/Access Point which I'll refer to as my access point (AP). The AP supports about 900Mbps. I'm fine with this bottleneck for now as I intend to upgrade my AP in the future

My goal here is to purchase a router that supports the 1.5Gbps that's coming from my ISP's modem. I'd like to use it to set up a VLAN and tinker with, with the ability to connect 4 devices in addition to my access point.

The problem I'm facing is that I haven't yet found a router that's <$200CAD which supports 1.5Gbps. There are probably brands I'm unaware of, so would you fine folks be able to recommend me a router?

Does anyone knows why most Epyc CPUs and MB on eBay are shipping from China? Does anyone here has experience buying a used CPU/MB from China?

I've been using a sound bar from Sonos with my TV for several years now, but in an effort to ditch the last appliances that unnecessarily require accounts and internet access, I am looking to ditch it in favor of something that is entirely contained within my own network.

What I think are my requirements:

• No microphone
• Ability to directly play audio from my Android (running Calyx OS), something I cannot do with the Sonos.
• HDMI ARC-connection to TV so that it can be controlled by my remote
• Sound must not be abysmal, but I am no audiophile. Preferably stand-alone without subwoofer
• Maximum 90 cm in length so that it fits under my TV, preferably in black / dark grey with a clean look

So far I've found something like this, which I believe gives me enough flexibility with HDMI ARC, Bluetooth and 3.5mm, even though it comes with a subwoofer: https://www.tcl.com/eu/en/soundbar/p733w

In terms of software, I have long been considering something like balenaSound to replace the Sonos functionality, but I'll soon be setting up Home Assistant to run my lights, and I see that there is a Snapcast integration that might work for me here?

Are there anyone here who have done something similar and have found setups that work well or that I should stay away from?

Based on an r210 II I'm currently doing up

• Orico HB-325 3.5 to 2.5 inch Hard Drive Caddy - don't even bother. Could be useful in a CRU sled, but I don't have a dell one to hand.
• SilverStone SDP08B 3.5" to 2 x 2.5" Drive Bay Converter Getting better, but all four screws don't align in the dell caddy
• SilverStone SDP08B, 3.5" to 3 x 2.5" Drive Bay Converter Absolutely perfect.

random info I thought may be useful to others

I may have the options between two Mikrotik l009 routers or a single rb5009. Which route should I go?

Dumping info for whoever needs it in the future. I had mine apart and used the opportunity to scan then cooler and measure the positions of the mounting holes. If anybody plans to manufacture their own cooler or make another cooler fit - here's the measurements you need. Image is calibrated in X and Y.

So, this open computer has been my homelab for a good while now, but I desperately want to upgrade it, so please recommend any hardware/upgrades.

Edit: I will use this server primarily as a media server! (shock) Edit2: I'm based in Norther Europe, so Amazon is not an option for me.

Current hardware: /What you see on the picture

• Motherboard: B250M Performance
• GPU: Nvidia GTX 1080 (defect, runs like an airport as soon as it needs to do 'a heavier task')
• CPU: Intel(R) Core(TM) i5-7500 CPU @ 3.40GHz
• CPU Cooler: Some cheap XILENCE fan
• RAM: 16 GB
• PSU: WPM600 Bronze
• Case: Custom company (defo want to replace)
• Storage: 1TB HDD + (2TB HDD but dead)

What I have to spare from previous build;

• GPU: Nvidia GTX 1060
• CPU Cooler: AMD Stock fan (doesn't fit this motherboard)

I've spent far longer than expected to set up an VLAN on my network for IoT devices which I don't want to have access to the internet. I'm running RB4011iGS+ router with RouterOS 6.48.4 and what I thought was a simple change took the whole network down for a while.

Granted, I'm not the most skilled network admin around, but I have built networks in the past and I'm (partly) maintaining them at work, but apparently I'm approaching this somehow from the wrong angle.

The current setup is a single subnet (172.17.0.0/24) where Mikrotik manages firewalling and DHCP without VLAN. WAN side has SPF module for the uplink, couple of bridged ports for that to provide raw internet to my server, some static mappings on the DHCP and things like that, pretty basic stuff. Other hardware includes Unifi access points, manageable switch and various stuff which just connects to the network.

Now, I'd like to add a VLAN (id 20, not that it matters) on the setup so I could have another /24 subnet for IOT devices. What I tought would be enough to take couple of ports from the existing LAN bridge, create a new bridge, set up an VLAN interface with IP, DHCP server and just connect tagged port on my switch, connect laptop for testing for untagged port and configure switch so that I could have another SSID on access points on that VLAN and connect couple of other things directly on the switch.

There's plenty of guides around the net, but when I attempted to follow them I ended up in a situation where untagged port just would not work with ARP. I could dump traffic on my laptop with wireshark and there's ARP 'who-has' requests running, but Mikrotik won't reply on those no matter what I do. Same of course goes with DHCP requests and all traffic in general. My laptop would receive ARP query when attempting to ping it from the router, and laptop would respond, but sniffing traffic from the mikrotik port the reply just disappears somewhere. No matter if I have the switch in between to untag VLAN for the port or directly connecting cable to the mikrotik or even moving the laptop to VLAN20 and using that as a test setup.

What I'm currently assuming is that the problem is with non-tagged "general" network I'm running. As in VLAN20 and VLANnothing somehow are fundamentally incompatible on RouterOS, but that seems kind of backwards.

The end goal would be to have a trunk port on the router and on the switch and distribute VLAN to ports as needed. Or even a port for generic use and another for VLAN networks. Maybe someone here is more experienced with RouterOS and could point me to the right direction?

Just bought Cyberpower OR700 1U UPS (20lbs). Will I need rack mount rails to support the back or will the cage nuts at the front be enough to support the UPS?

Hello fellow Homelabbers,

I am in the process of setting up my first homelab and taking my first steps in self-hosting. I got an old pc as a gift from a friend and I want to convert it together with my old pc into 2 2U servers.

But first of all I need an enclosure where these servers and the rest of my equipment can go in. Since this homelab will be located in my flat for the time being, I don’t have a particularly large amount of space for it. I think a size of 15 to 22U would be perfect, also in terms of long-term upgrades.

I have looked around on my local online marketplaces but I am not sure what I should really focus. Since this purchase will literally be the foundation of my future upgrades, I don’t want to rush into anything and would like to ask you homelab veterans for some advice.

Thanks in advance.

Sorry, I'm not very used with server stuff, if I buy an Intel CPU without an integrated GPU like most Xeon, then I wouldn't have enough pcie lanes for a GPU because all is taken for nvme drives

Specifically, the motherboard ipmi is powered by aspeed ast2500

If I understood right, that chip will act as a 2d basic graphics card that's enough to see what happens that day the server is unresponsive

I don't plan to connect a monitor, it's just that I'm scared if I break truenas and I can't connect via ssh, then I could still see the local screen from the management Page on the browser

So, I just realized that if i use my WAN IP in my browser from within my network, it brings me to my pfsense login page..

At first I panicked thinking this was also accessible externally, but luckily it is not.

I have rules in place to prevent devices from accessing the GUI unless they're part of an alias, however if I access it in this way, it bypasses the check.

Why is my WAN IP resolving to my pfsense login?

Edit: As just about everyone has mentioned, this seems like NAT Reflection, however I have this disabled everywhere I've found. Here is the setting in System>>Advanced>>Firewall & NAT as well as in the individual NAT rules as seen here

Outbound NAT

Port Forwards

Hey all,

I've been using Proxmox for some time and have several VLANs that I use across my VM's.

I have a trunk to my Proxmox server that is tagged with these VLANs, and everything seems to be working as I expect.

The question I have comes from early today when I was adding a new VLAN to my Proxmox server to use in a VM, and noticed that I do not seem to have the actual VLAN ID's like I remembered (maybe this changed between Proxmox VE 7 to 8?) and instead I only have comments here.

When I check the config in shell, I see this, and it appears all VLAN ID's are allowed.

My question is, how can I limit this to only the desired VLAN ID's (100, 200, 300, etc) and not that entire range? Is there a GUI option or should I just modify that config? If I modify the config, do I just enter them comma seperated?
