 1. Harden your SSH server.  There are some tips [here](https://linuxhandbook.com/ssh-hardening-tips/), but three simple actions to take are:
 
-    1. [Change the default SSH port](https://linuxhandbook.com/change-ssh-port/) from 22 to something else.

+   Change the default SSH port from 22 to something else.
 
-    1. [Disable password login](https://linuxhandbook.com/ssh-disable-password-authentication/) and use only SSH keys to authenticate.
+   The specific method of doing this will vary with the version of Ubuntu you are using.
 
-    1. Disable root login.

-2. Set up [scheduled backups](../backup/backup.md). **There is no backup enabled automatically**, so unless you explicitly set them up, you will be disappointed to find that you don't have a backup when something goes wrong.

     You need local disk space for stuff between download completion and cloudplow moving things into the cloud.  If you don't, for example, set cloudplow's upload thresholds and Nzbget's "stop downloading" disk space threshold to meaningful values for your situation, you can get into a situation where cloudplow's not uploading because that threshold hasn't been met and nzbget has stopped because its threshold has been met and everything grinds to a halt.  Alternatively, nzbget just keeps going and runs your disk out of space.
 
     You also need a bunch of disk space for the [scheduled backups](../backup/backup.md) that you just set up to succeed, so be sure to take that into account.
 
     Another common "hidden" disk space consumer is unfinished or unimported downloads.  If NZBGet downloads something and Radarr can't tell what movie it is, it will just sit consuming disk space.  There is a script you can set up to keep this stuff cleaned up in the [user crontab examples](../../advanced/user-crontab-examples.md).
 
-4. Spend some time working with the system before you start customizing.  A **lot** of problems are seen when new users rush ahead to install All The Things and customize the system without understanding how things work.  Slow down.  Learn how the thing works, and then make changes in a controlled manner.

     None of these apps or scripts are sentient, so if they are not doing what you expect, it's almost certainly a configuration problem.
