This document holds various notes on ssh & scp.

• ssh & scp
  • connect to client
  • generate ssh key

connect to client

In order to connect to a client use the ssh command with user and address as arguments. Here some examples:

# connect as user on remote device
ssh <user>@<ip>
ssh pi@155.1.1.120

# connect as user via url
ssh <user>@<url>
ssh user@github.com

generate ssh key

To generate a ssh keypair use ssh-keygen:

ssh-keygen -t ed25519
# or
ssh-keygen -t ed25519 -C "email@address.domain"

Place the generated keypair in $HOME/.ssh (on linux systems). The *.pub file is the public key and the one to upload to github and Co.

Important: double check that you never upload the private key!!
