create_ssh_key_for_remote.md

1. on local machine - create ssh key-pair mykeyfile, mykeyfile.pub

$ ssh-keygen -q -N '' -b 4096 -f ~/.ssh/mykeyfile

2. on local machine - display contents of public key (so that later you can copy/paste them into authorized_keys)

$ cat mykeyfile.pub

3. on remote machine - create file ~/.ssh/authorized_keys (if not already exists), add the contents of public key as a new line into that file

$ nano ~/.ssh/authorized_keys

4. on local machine - add configuration for remote-machine to local ssh-config (you can use VScode for that)

$ nano ~/.ssh/config
Host myremote                       <- alias
  HostName my-remote-machine.lan    <- hostname or ip
  User myremoteuser                 <- user-name on remote machine
  Port 22                           <- (optional) ssh port of remote-machine, if not default, for example: 2222
  IdentityFile ~/.ssh/mykeyfile     <- path to private (!!) key, not public

5. on local machine - test ssh-connection to remote machine

$ ssh -Tvvv myremote

6. on local machine - connect to remote

$ ssh myremote
