→Copying your Public Key Using SSH
The full command will look like this:
<pre class="code-pre "><code>cat ~/.ssh/id_rsa.pub | ssh <span class="highlight">username</span>@<span class="highlight">remote_host</span> "mkdir -p ~/.ssh && cat >> ~/.ssh/authorized_keys"</code></pre>
You may see a message like this:
<pre class="code-pre "><code>The authenticity of host '111.111.11.111 (111.111.11.111)' can't be established.
ECDSA key fingerprint is fd:fd:d4:f9:77:fe:73:84:e1:55:00:ad:d6:6d:22:fe.
Are you sure you want to continue connecting (yes/no)? yes
This just means that your local computer does not recognize the remote host. This will happen the first time you connect to a new host. Type "yes" and press ENTER to continue.
Afterwards, you will be prompted with the password of the account you are attempting to connect to:
<pre class="code-pre "><code>username@111.111.11.111's password:</code></pre>
After entering your password, the content of your <code>id_rsa.pub</code> key will be copied to the end of the <code>authorized_keys</code> file of the remote user's account. Continue to the next section if this was successful.
