I like it, it was released a couple of days ago so something might require a bit more polishing but overall it looks better to me.

Considering the small audience and purpose, I would not have any problem using the always free offerings of either Oracle or Google (the latter especially if located in the US).

I don’t know, wouldn’t the Hypervisor be able to track resources usage by itself without anything else?

Thanks for the suggestion, but my 24 GB are well employed already. I wanted at least to outsource the VPN manager to a smaller VPS.

Running without docker is out of question, is a bundle of 6 docker containers. Deployment and management without it would be too complicated. Luckily somebody in another reply made me realize that the RAM eating container (cockroach DB) is far less essential than I thought and I can look for a replacement.

The one managing my VPS, controlled solely by Oracle corporation

Yes exactly, burstable instances it’s common jargon for AWS and GCP, but applies to all major providers.

I forgot to mention, I had plenty of swap available, now I disabled swap to force zram usage. I still need to see what happens running with both, it’s hard when each trial takes 12-24 hours to show its result.

I am experimenting with ZRAM, it is indeed better than ZSWAP, that’s why i am asking if any other kernel features can help.

This service consist of several docker containers, without docker I would not even know where to start for deploying it. Maintainance as well would be a mess, totally not an option

I believe it’s a shared VCPU intentionally, I will recheck the terms and conditions, but I think I am not in the position to claim much.

Yes, this is a possible fallback plan.

Yes, this is a possibility. the ARM VPS is already running something else, but if I manage to run netbird behind a reverse proxy I can also move it there. BTW there are also 1 GB free VPS on azure (for students) and Google Cloud, but you guessed right.

The server is clearly overloaded, as soon as I start using some 10% of CPU frequently for some minutes (due to swap operations), the Hypervisor starts to throttle my instance and this of course makes the thing worse with an avalanche effect. When this happens steal time displayed from top can go literally as high as 90%.

If postmarket os works on that device maybe you can go full Linux (alpine), there will be no systemd which might be a problem and I am not even sure about docker compatibility. You can look it up though.

Relays have become a pro feature in the last release. I tested them on netmaker.io SaaS version and they work but it defeats the purpose of selfhosting my VPN manager. You also need to have a good relay, for instance among GCP, Azure, Oracle and Vultr only the latter works because their VPS are not behind a NAT.

Netbird first of all is extremely resource hungry. In some occurrences completely hanged a 1 GB RAM VPS when I was testing. Even without trashing I had issues connecting many of my peers. It has to be said that it was surely my fault in some ways as netbird.io SaaS worked fine.

Tailscale just works, I recently tried netbird and netmaker. I did not manage much with the first but netmaker instead seemed even easier to manage than tailscale, being faster at the same time. Unfortunately it failed with peers behin my corporate NATwhich tailscale can bypass with its own relays. But for others it can work very well.

Hi, to check attacks you should look at the logs. In this case auth.log. Being attacked on port 22 is not surprising neither really troublesome if you connect via key pair.

My graph was showing egress traffic, on any kind of server the traffic due to these attacks would have been invisible but on a backup server which has (hopefully) only ingress you can clearly see the volume of connections from attackers from bytes teansmitted

ssh -p 12345 would leave your boxes accessible from anywhere too. Other blocks of IPs receive 10 times or more requests, as scanners can focus on blocks of ips from major providers.

I disagree, you’ll have your backups, so even if everything breaks you will have a failsafe. If you get compromised it’s still not an issue: Everything server side is encrypted, the safety is in the clients and your master password length.

So, I see no particular differences with other services. Considering I hear of some issues with bitwarden servers that are constantly under attack, selfhosting could even increase the availability.
