- Platform information:
- Hardware: Raspberry Pi 3B
- openHAB version: 3.2.0
- Issue of the topic:
with Openhab 3 somehow i cant make my ssh Commands to other raspberry pis working again.
How I generate the key:
sudo -u openhab ssh-keygen -t rsa -f /etc/openhab/sshKeys/pi.id_rsa
Then i copy the key to another raspberry pi:
sudo -u openhab ssh -i /etc/openhab/sshKeys/pi.id_rsa USER@IP
Then it always fails to add the host to known_hosts file. I never need a password to ssh the other pi, but i always need to confirm i want to access
dont know why its failing
I´m thankfull for your hints! 
Do you already have a directory /var/lib/openhab/.ssh/?
ls -la /var/lib/openhab/ to show hidden files.
If not, create one:
sudo -u openhab mkdir /var/lib/openhab/.ssh/
sudo -u openhab chmod 700 /var/lib/openhab/.ssh/

Thanks for the fast response. Yes, I have the.ssh folder:
drwx------ 2 openhab openhab 4096 Apr 9 09:49 .ssh
And still no luck?
touch the file then:
sudo -u openhab touch /var/lib/openhab/.ssh/known_hosts
If the file exists, ensure it belongs to user openhab:
sudo chown openhab: /var/lib/openhab/.ssh/known_hosts
sudo -u openhab chmod 644 /var/lib/openhab/.ssh/known_hosts

That’s was it! I could not touch the file due to permission issue, the other commands solved it.
I just wonder why the file in the openhab folder doesnt have permission for openhab. I just checked the .ssh folder.
Next time i know it better, thank you Udo
