1) Prep the linux system for remote access:

mkdir $HOME/.ssh
chmod -R og= $HOME/.ssh

Note: file must be mode -rw-------

2) Run puttygen.exe on the client to generate a public/private key-pair.

3) Save the private key locally on the client
4) Copy the key directly from the output window of puttygen
5) Paste into the file $HOME/.ssh/authorized_keys as a single line.
6) Under putty, locate the SSH -> Auth -> ensure to select the proper private key file for authentication
