"Host key verification failed." is the indicator here. You need to attempt to ssh into the remote computer as the local weewx user (probably root) at least once so that ssh saves the other side's host key. When it prompts you, say yes.
It should look something like this example: # ssh testuser@pi The authenticity of host 'nuc2 (192.168.1.171)' can't be established. ECDSA key fingerprint is 4e:8a:b5:6a:12:a2:a0:6d:f6:64:07:35:d0:e7:17:1b. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added 'nuc2,192.168.1.171' (ECDSA) to the list of known hosts. Lastly, your log and weewx.conf show a user name of 'remote_user' which I'm hoping is a typo. If it's what you really want, you will need a user named "remote_user" created on the host you want to rsync to, and they will need to be able to write to whatever directory on the remote side that you specified in weewx.conf or you'll get permission errors. -- You received this message because you are subscribed to the Google Groups "weewx-user" group.
