SeaTools is a long-standing, trusted tool for HDD testing. I always have a bootable drive with the SeaTools bootable image on me for diagnosing hard drives.

Keep in mind that testing a failing drive will likely make a failing drive worse. For your use-case this is fine, but for anyone else looking to test drives, please create a backup image of the drive prior to testing.

ADMIN, isn’t it time to move from lemmy.world?

They said, from their lemmy.world account.

The old name is draw.io with the self-hosted version keeping that name. The current name is diagrams.net hosted on their servers.

In the end, it’s all the same

I don’t technically open any ports to the public. I have a site-to-site wireguard tunnel to a hosted server. The hosted server is running a hypervisor with two virtual switches. One switch is my external switch and only my Wireguard server is using it. The other is an internal switch where I place other VMs for separate things. A container host, a terminal server with xrdp, a monitoring server with netdata, stuff like that. All technically, but unnecessarily, accessed through nginx proxy manager.

Because it’s site2site with my home equipment on the Wireguard server, i can still connect to my home network where i host a number of separate services like HomeAssistant from outside the home network.

I don’t use tailscale, but Wireguard vanilla is super easy to work with. I also have fail2ban pretty much everywhere I can install it because it takes up practically zero resources.

I’m thinking of starting something similar. What kind of specs are you using for your host?

I’m concerned about RAM and disk space for this in my personal setup

I don’t use OMV so take this with a grain of salt, but I would hazard a guess that the web server isn’t listening on port 80.

Try ss -ltn for a list of ports on which the system is listening and ss -nut for a list of active connections. Double-checking firewall rules (commonly ufw) or filter rules (iptables) will be useful for diagnosing connection issues.
