  • SNMP does what you want. You just need a good monitoring solution that’s not as involved as Prometheus+grafana (I feel you, I’ve been there)

    I really enjoy PRTG, but it’s way too expensive for a home lab, still throwing it out there if you feel like you have money to burn.

    I hear good word about libreNMS, it’s next on my list when my PRTG licence runs out.

    Be warned that monitoring is ultimately a fickle thing; what you don’t write in yaml config for grafana, you get to dig through obscure SNMP libs to find out (though I find that’s easier for me, ymmv) for other tools.

    I recommend against: nagios (I like it but if you hate Prometheus it’s definitely not for you), checkmk (throw checkmk into the sun please it just fucking sucks), cacti (NO!), solar winds (why?)

    if you feel like you want to become a datacenter admin: zabbix scales very very well, both in performance and ease of admin against hundreds of servers, but it’s overkill for a home lab, and it can get you lost in configs for hours.




  • I’m not fully familiar with the overheads associated with all things going on on a chipset, but it’s not unreasonable to think that this workload, plus whatever the chipset has to do (hardware management tasks mostly), as well as the CPU’s other tasks on similar interfaces that might saturate the IO die/controller, would influence this.

    B350 isn’t a very fast chipset to begin with, and I’m willing to bet the CPU in such a motherboard isn’t exactly current-gen either. Are you sure you’re even running at PCIe 3.0 speeds too? There are 2.0 only CPUs available for AM4.













  • So to be clear, you want traffic coming out of your VPS to have a source address that is your home IP?

    let’s go back to fundamentals and assume for a second that your VPS provider allows these packets out and your VPS initiates a TCP connection like that. It sends a TCP SYN with source: home address and dest: remote.

    The packet gets routed to the remote. The remote accepts and responds SYN/ACK with source: remote and dest: home address.

    Where do you think this packet will get routed? When it gets there, do you think the receiving server (and NAT gateways in between) will accept this random SYN/ACK that doesn’t appear to have a corresponding outgoing packets sent first? If so, how?
