Creating keys, if don't have it yet
ssh-keygen -t dsa
or
ssh-keygen -t rsa -b 4096

Copy public file content (id_dsa.pub) to ~/.ssh/authorized_keys on REMOTE site

ssh server use authroized_keys as public key of client to check validity

• PuTTY key file formats seems not match with linux/solaris ssh, or need change to make it compatible
