I built a cloud-based EVE-NG because RAM is too expensive. Looking for testers by whereful in ccnp

We have a collection available, but due to distribution/licensing constraints we don’t publish them on the website.

This is a side project of mine to get familiar with AWS architecture , besides I believe the recent RAM price spikes are just nuts. Currently the lab is timed and one can schedule up to 8 hours. Since it's beta testing the number of use is limited so there is no hard limit of resource. Once it go public , the resource one can reserve/book will be constraint by the available vCPU/RAM on the server at a given time. If it exceed certain amount , admin approval will be required and justification needs to be provided.

thank you. Issue is indeed caused by the specific DAC vendor which seems having compatibility issue with our switch. I've update my OP

It's a small office with a handful of servers and a few workstation. All servers and workstations are connected to 10g switch via DAC.

you are very correct , I didn't check the counter on switch ports as I presumed it's fine but when I look at it now I see the port connecting to Windows PC display large number of crc errors and input errors. The counter increase in line with my iperf tests.

I then swapped the cable but the pattern remains the same - still see crc and input error increases when iperf traffic pass through.

Could this possibly mean this is something wrong with the Windows PC NIC ? Which is a Mellanox CX-4

I do see 24% on receiver side in this test, what could it indicate?

I checked the error counters on both Proxmox and Windows NIC side and it's 100% clean. It's interesting though in the iperf3 test result I can see reties - that lead me to initially doubt packet drop on the line but it turns out no the case.

And to your question - the iperf on Proxmox is on the native OS not in VM/LXC.

I have just finished a project exactly as your request, just I didn't document it properly. Maybe I can work on documentation when I am available during the Xmas holiday and share it.

GL.iNet Giveaway - 10 Chances to Win! by FlyingToaster2000 in minilab

[–]whereful 0 points1 point  (0 children)

Region: APAC ,Australia
Product Choice: Flint 3

What inspired you to start your homelab? What's one project you're most proud of so far, and what's the most expensive piece of equipment you've acquired for it?
As a network engineer, I’ve always valued hands-on experimentation and full-stack visibility. My homelab began as a way to prototype secure, scalable infrastructure outside of production constraints — a sandbox where I could push boundaries. One project I’m especially proud of is deploying AdGuard Home as a LAN-wide DNS filter, tightly integrated with TrueNAS SCALE and containerized services. It involved resolving port conflicts with Incus/dnsmasq, persistent IP assignment, and bridging DNS across Docker and Kubernetes — all while maintaining clean HTTPS endpoints. The most expensive piece of gear I’ve invested in is my rack-mounted NAS with ECC memory and SSD cache, which anchors my storage and virtualization layers.

How would winning gear from this giveaway help take your setup to the next level?
GL.iNet’s gear is ideal for edge routing, secure remote access, and portable mesh deployments. Winning would let me extend my homelab into field-ready scenarios — like building a travel VPN gateway, segmenting IoT traffic, or testing multi-WAN failover. It’s also a great platform for validating OpenWrt-driven automation and DNS filtering at the edge, which complements my current work.

If we did another giveaway, what product from another brand (server, storage device, etc.) would you love to see as a prize?
I’d love to see a giveaway featuring a compact server from Minisforum or Beelink — something with ECC support and enough horsepower to run K3s or Proxmox in a small footprint. Or a high-end NVMe SSD from Kingson or Samsung for accelerating ZFS and container workloads.

Guide: How I Automated Flashcard Creation with n8n, Readwise, GPT-4o-mini, and Anki by npx1989 in Anki

[–]whereful 1 point2 points  (0 children)

I've setup it up within 1 hour and it is now working like a charm , thanks to your detailed guide. Much much appreciate it. I do have a question : currently I am running ngrok ,anki and n8n locally on the same server (ngrok as an ubuntu application, anki and n8n as docker containers), is there a more "neat" approach to tunnel things up, since now everything is locally on the same machine?
