Preconditions:
You have the public-private key pair, and use default names ~/.ssh/id_rsa.pub + ~/.ssh/id_rsa.
If your security rules allow, don’t set the passphrase. You can also remove the passphrase from already existing ssh key.
If they don’t, generate them:
ssh-keygen -t rsa
Now install the key on remote host:
cat ~/.ssh /*.pub | ssh user@remote-system 'umask 077; mkdir -p .ssh; cat >>.ssh/authorized_keys'
ssh user@remote-system should work now, so should scp user@remote-system:/your/file. And if you chose to have no passphrase you will login automatically
