I found this helpful video from CJ over at the Syntax podcast where he goes over some basics about self-hosting and VPS safety measures.

I dusted off my Tab S7+ and reused the SSH keys I had generated last year for GitHub access to login to Mojave.

First, as root I created a new user: $ adduser nyoki. At the prompt for a new password I provided a different one from the root user and left the default info blank.

Adding SSH key access for nyoki from Tab S7+

Over on Café Quito, I created the .ssh directory in the new user’s home directory (/home/nyoki).

Just for fun, I ran $ cat ~/.ssh/id_ed25518.pub on the tablet and proceeded to manually type the entire SSH key into the /home/nyoki/.ssh/authorized_keys file.

This worked wonderfully. Like magic, typing ssh nyoki@IP_ADDRESS on the tablet logged me in without prompting for a password.

Cool.

Adding a new SSH key to access Mojave as nyoki from Café Quito

I’ll be generating a new set of SSH keys for Café Quito to login as nyoki.

First I ran $ ssh-keygen -t ed25519 -a 100 (command taken from tilde.team) and manually wrote the filename and the comment, but the alternative $ ssh-keygen -t ed25519 -a 100 -f ~/.ssh/id_ed25519_custom -C "" does it all in one line.

I added the public key to nyoki’s /home/nyoki/.ssh/authorized_keys file. To login by simply typing ssh nyoki@mojave from my terminal, I edited my local ~.ssh/config file:

Host mojave
  Hostname ID_ADDRESS
  User nyoki
  IdentityFile ~/.ssh/id_ed25519_mojave

That did the trick.
