Machine wise anything will work. Give yourself a chassis with room to add more disks down the road or just build your storage setup in a way that gives you what flexibility you need (though that tends to come with sacrifices).
I use Nextcloud for general file syncing between devices as occaisonal small file sharing.
Mulvad is great but if you need port forwarding you’ll have to look elsewhere as they no longer provide that feature.
I use keepass2android and “sync” via its native WebDAV support with my nextcloud instance as the source. Been working great forever.
Ah, well, then perhaps I will monitor it.
For internal use I just monitor everything with zabbix. What Ive been wanting is (as I said) a public “status screen” that my few users can hit just to verify if things are in fact down or if it’s just them.
Ok, you might have finally gotten me to consider a “dashboard”. I’ve been wanting a simple public facing service status page and this sounds like a nice solution.
Haha, I’ve never had to deal with something quite that high pressure but I’ve definitely been a little looser than standard during at least a couple emergencies.
Kernel upgrade WHILE you’re out for beers!
Someone just posted their own short reviews of a slew of wiki options in this community so maybe go take a peek at that.
Personally I’m finding I like Otterwiki quite a lot though I’ve not yet dug deep into it.
I use portainer extensively and am quite fond of it. I normally live on the CLI so picking a GUI tool over cli management is unusual for me but I’ve found portainer largely just makes typical management easier and doesn’t get in my way at all.
For your other questions I have no answers. I self host everything so to me “what is worth running” is not a question that makes sense. I run what I need and my needs therefore define what I run.
I stick to IRC over matrix.
500Mbps isn’t a measurement of electrical consumption
Check out the Teamspeak6 beta. I don’t know about offline messages but it addresses all your other complaints. I moved to it from Mumble somewhat recently and have been very happy with it.
