OctoPrint SSH Credentials - Shell/Bash

OctoPrint is a popular open-source 3D printer control software that allows you to remotely control and monitor your 3D printer. One of the ways to interact with OctoPrint is through SSH (Secure Shell) protocol.

To access OctoPrint via SSH, you need to have SSH credentials set up. These credentials consist of a username and password that are used to authenticate you as a valid user. Here's how you can create SSH credentials to access your OctoPrint instance:

1. Open a terminal on your computer and navigate to the directory where your SSH key is stored.
2. Run the following command to generate SSH credentials:

ssh-keygen -t rsa -b 4096 -C "your_email@example.com"

3. You will be asked to provide a location to save the key, and a passphrase to encrypt it. You can leave these blank if you prefer.
4. Once the key is generated, run the following command to copy it to your clipboard:

cat ~/.ssh/id_rsa.pub | pbcopy

5. Log into your OctoPrint instance and navigate to the SSH section in the settings.
6. Paste the copied key into the "Authorized Keys" field.
7. Save the settings and you're done!

Now you can access your OctoPrint instance via SSH using the following command:

ssh username@<your_octoprint_ip_address>

Replace "username" with the username you set up in the SSH settings, and "<your_octoprint_ip_address>" with the IP address of your OctoPrint instance.

With SSH access to OctoPrint, you can perform various tasks such as updating plugins, creating and deleting files, and executing commands directly on the Raspberry Pi that's running OctoPrint. It's a powerful tool that every 3D printer enthusiast should have in their toolkit!
