I’d like to manage the clients while they are running.
I need to reboot or debug the client, if it isn’t doing its job correctly.
I now added an authorized_keys file to the root account and it works.
Thanks!

It’s true, there is not password set in /etc/shadow, but SSH asks for any…

I get a prompt for password: (192.168.41.23 is the fog client running in debug mode)

ssh 192.168.41.23

The authenticity of host ‘192.168.41.23 (192.168.41.23)’ can’t be established.

Are you sure you want to continue connecting (yes/no)? yes

Thanks a lot for the tip, it works. But where can I find the password or the key?

I tried to put dropbear on the fog client (init.xz), but even if I use 32bit or 64bit it says “binary execution error”.
How do I add a ssh server to the fog client?
