Buster setup ssh
Openssh is installed in our default Debian image, but by default openssh does not permit root logins, and requires a password to be set. Additionally, a host key is required if one hasn't already been created on the target board. To allow remote root login:
sed --in-place 's/#PermitRootLogin prohibit-password/PermitRootLogin yes/' /etc/ssh/sshd_config systemctl restart ssh.service /bin/ls /etc/ssh/ssh_host*key >/dev/null 2>&1 || ssh-keygen -A passwd root # Set any password
If you ssh to this system it will now support ssh as root.
