 ====== Set Up SSH Keys ======
+===== Common Use =====
 Use this command to set up your SSH key on a remote server that you log into frequently:
 <file>
-ssh-copy-id root@www.yourdomain.com
+ssh-copy-id user@remote.host.name
 </file>
-Or if the ''ssh-copy-id'' script is not available:
+===== Without ssh-copy-id =====
+If the ''ssh-copy-id'' script is not available:
 <file>
-cat ~/.ssh/*.pub | ssh user@remote-system 'umask 077; cat >>.ssh/authorized_keys'
+cat ~/.ssh/*.pub | ssh user@remote.host.name 'umask 077; cat >>.ssh/authorized_keys'
 </file>
-or if SSH is on a non-standard port:
+===== Non-Standard SSH Port =====
-cat ~/.ssh/*.pub | ssh -p 2222 root@www.sonoracomm.com 'umask 077; cat >>.ssh/authorized_keys'
+If SSH is on a non-standard port:
-If no public key yet exists on the machine you will be using to make remote connections:
+<file>
+ssh-copy-id -p 2222 user@remote.host.name
+</file>
+or:
+<file>
+cat ~/.ssh/*.pub | ssh -p 2222 root@remote.host.name 'umask 077; cat >>.ssh/authorized_keys'
+</file>
+===== Generate Public Key =====
+If no public key yet exists on the machine you will be using to make remote connections, you'll need to create one.  This is only done once:
+<file>
+ssh-keygen -t rsa
+</file>
-ssh-keygen -t dsa
+You probably want to just hit enter at the passphrase prompt.
