+= Set up SSH public-key authentication =
+
+Using SSH public-key authentication to connect to a remote system is a robust, more secure alternative to logging in with an account password.
+
+See if you have public-key generated.
+
+{{{
+local:~ user$ ls ~/.ssh
+config id_rsa id_rsa.pub known_hosts
+}}}
+
+
+
+***.pub is your public-key. If you don't have it,
+{{{
+local:~ user$ ssh-keygen -t rsa
+}}}
+
+You will be prompted to supply a filename (for saving the key pair) and a passphrase (for protecting your private key):
+
+Filename: To accept the default filename (and location) for your key pair, press Enter or Return without entering a filename.
+Password: If you press Enter or Return without entering a passphrase, your private key will be generated without password-protection.
+
+SCP to copy the public key file (e.g., ~/.ssh/id_rsa.pub) to your account on the remote system (e.g., usersID@cypress.tulane.edu);
+{{{
+ local:~ user$ scp ~/.ssh/id_rsa.pub usersID@cypress.tulane.edu:
+}}}
+Don't forget ':' 
+You'll be prompted for your account password. Your public key will be copied to your home directory (and saved with the same filename) on the remote system.
+
+
+
+
+Log into Cypress using your account username and password.
+{{{
+local:~ user$ ssh userID@cypress.tulane.edu
+}}}
+
+You must have "id_rsa.pub" on your home directory
+
+{{{
+[user@cypress ~ $] ls id_rsa.pub
+id_rsa.pub
+}}}
+
+On the remote system, add the contents of your public key file (e.g., ~/id_rsa.pub) to a new line in your ~/.ssh/authorized_keys file; on the command line, enter:
+{{{
+ [user@cypress ~ $] cat ~/id_rsa.pub >> ~/.ssh/authorized_keys
+}}}
+
+You may now safely delete the public key file (e.g., ~/id_rsa.pub) on Cypress; on the command line, enter:
+
+{{{
+  rm ~/id_rsa.pub
+}}}
+Now you should be able to login Cypress without typing password from next time.
