SSH config notes

Some examples from my .ssh/config file.

All my automatically installed Raspberry PIs are in the same tinc within the same group of ten. I use archlinuxarm, so I want to use the user alarm as my default. The IP address range is from .20 to .29.

On the rare occasion I have to manually create an AWS server, I need this.

Host manual-aws-server
  User ubuntu
  IdentityFile ~/.ssh/given-certicate.pem

Login with custom user, custom port and specific certificate only for this system.

Host custom
  HostName custom.local
  User username
  Port 8022
  IdentityFile ~/.ssh/custom-local-id_ed25519
