SSH Public Key Authentication

rsync -av -e "ssh -p 2222" ~/.ssh/id_dsa.pub [email protected]:.ssh/authorized_keys

This adds the public key to the authorized_keys file in your ~/.ssh directory on the remote machine. You can specify a port other than 22 with -p####.

You can also copy the ssh key to the clipboard and manually add to authorized_keys on the remote machine while logged via SSH:

pbcopy < ~/.ssh/id_dsa.pub

Copy and paste from Linux:

cat ~/.ssh/id_dsa.pub

and in ~/.ssh/config locally:

#Devbox
  Host ShortName
  HostName targetDomain.com
  PreferredAuthentications publickey
  IdentityFile ~/.ssh/id_dsa
  User mark
