====== 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 user@remote.host.name
</file>

===== Without ssh-copy-id =====

If the ''ssh-copy-id'' script is not available:

<file>
cat ~/.ssh/*.pub | ssh user@remote.host.name 'umask 077; cat >>.ssh/authorized_keys'
</file>

===== Non-Standard SSH Port =====

If SSH is on a non-standard port:

<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>

You probably want to just hit enter at the passphrase prompt.
