+===== Remote Management using SSH =====
 If you prefer (or have to use) a command line for managing Blocks, here's a video showing you how to do this. SSH is a terminal command available on all major operating systems, allowing you to log in to a remote computer, execute commands, copy files back and forth, etc, all using a secure and encrypted connection.

+==== Warnings ====
+If you log on to a computer that you e.g reimage you may see a warning like this. It may look a bit scary but the underlying reason is in that case that you already used ssh wo this ip or domain name and is is associated with differens ssh id keys. The intention of such warning is to make the user to consider if it is legit or not.
+{{:blocks:ssh:screenshot_2025-11-14_115333.png?600|}}
+Rather that editing the file the following commands can be used in the terminal to clear the associated keys and get ready for new ones:
+<code>
+ssh-keygen -R <ip or domain>
+</code>
+Example:
+<code>
+ssh-keygen -R 10.0.1.195
