Unable to copy disk image over SSH

general

I have done this in the past a handful of times with no issues but now I cannot seem to be able to:

I follow the steps in this guide: https://www.linode.com/docs/migrate-to- … e-over-ssh">https://www.linode.com/docs/migrate-to-linode/disk-images/copying-a-disk-image-over-ssh

I sat the linode on rescue mode.

I fire up my lish via terminal.

I set the root password.

I open a new terminal (local) and entered the command "root@XX.XX.XX.XX "dd if=/dev/sda" | "dd of=/Volumes/somedrive/linode.img"

I enter the password but then nothing happens….and by that I mean, the shell just returns right away as if a had control-C….and that is all.

what am I doing wrong? What changed?

Did you start the SSH service after setting your root password?

Yeah, absolutely.

Probably because your ssh client is now complaining that the fingerprints don't match.

Try just: ssh root@ipaddress when booted into rescue mode (after setting root pass and starting ssh). You may need to remove a line from your local known_hosts file.

It seems to me that if you've configured your linode as described here…

https://www.linode.com/docs/security/se … our-server">https://www.linode.com/docs/security/securing-your-server

i.e. for passwordless access and disabled root login, that you would need to temporarily disable those security protection settings prior to being able to perform the ssh-based dd command, and then re-enable it afterwards .

Or, does the linode's rescue mode act differently? does rescue mode allow root@linode-IP ssh despite the normal protection?
