🐢 Ah yes, the timeless art of turning tiny PCs into a "supercomputer" 🤖, because who doesn't want to spend their weekend fiddling with SSH keys and pretending they're building Skynet? 🛠️ Just remember, kids: #CV5 vs #CV10 is the Clash of Titans no one asked for! 😂

Setting Up A Cluster of Tiny PCs For Parallel Computing - A Note To Myself | Everyday Is A School Day

Enjoyed learning the process of setting up a cluster of tiny PCs for parallel computing. A note to myself on installing Ubuntu, passwordless SSH, automating package installation across nodes, distributing R simulations, and comparing CV5 vs CV10 performance. Fun project!

Anyone got an idea how to do this:

expose a user on a GNU/Linux system via ssh
allow two keys access
- one is the “self” key, which should be allowed as-is
- the other is the “external” key, which triggers a password prompt
otherwise, password login is not permitted

I know how to do most things of this, but not all at once (AuthenticationMethods is permitted in a Match block, but we cannot match on keys, we want access to the same user, and the “self” key can also be used (agent forwarding) from nōn-local addresses.

It seems like I’ll need a custom PAM module (arrrgh, I don’t want to write one of these) that asks for the password if key B is used (does SSH expose this to PAM?).

Anyone got a better idea?

in case you may have not known, if you have a #yubikey or an #onlykey or something similar you can generate SSH keys that require them, for example:

`ssh-keygen -t ed25519-sk`

Vorhaben: Rechner neu installieren und dabei alles dokumentieren.

Eine Sache, die mir bzgl. #SSH unklar ist: Kann ich mein .ssh-Verzeichnis der alten Installation auf die neue Installation übertragen und mit den schon vorhandenen #SSHKeys immer noch ne Verbindung zu meinem #PiHole herstellen?

Oder MUSS ich mir definitiv neue Keys erstellen? 🤔
