I'm following this guide so I can download a copy of the disk image as I want to migrate to another host. When I get to the stage where this command needs to be entered:
ssh firstname.lastname@example.org "dd if=/dev/xvda " | dd of=/home/archive/linode.img
(with the correct IP and a filepath of '/linode.img') I get a permission denied error, and I'm certain that I'm using the correct password as it works when normally logging in.
The strange thing is that it was working, but then after a disk image resize (I made it smaller as I was receiving an error saying there wasn't enough space when copying the image) it started giving me permission denied messages.
