Secure shell from a MacBook to Redhat server
For a while I have been trying to set up ssh to use a private/public key pair instead of requiring me to log in each time. I also hope that this will speed up Capistrano deployments of Ruby applications.
The instructions here did not work first time for me because I had assumed the ~/.ssh/authorized_keys file was a directory full of key files. Having read the instructions more clearly it turns out that its a single file containing multiple public keys.
And now it works.
