Setting up password-less ssh

1. Generate ssh key-pair for local workstation: ssh-keygen -t rsa ; accept default options and hit return when prompted for passphrase.
2. Copy public key (~/.ssh/id_rsa.pub) to remote system: scp ~/.ssh/id_rsa.pub remotesys:~/ If this is the first connection to the remote system, type yes to accept the remote system key.
3. Login to remote system, configure remote system to trust public key:

• ssh remotesys
• create ~/.ssh if it doesn't exist: mkdir ~/.ssh
• cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
• chmod 700 ~/.ssh
• chmod 640 ~/.ssh/authorized_keys
  1. Logout of remote system, and repeat login to check that everything works correctly. If so, ~/id_rsa.pub can be removed from the remote system.
