Is there a way to prevent this message:
Code:
root@100 [~]# ssh -q xxx.xxx.xxx.xxx
The authenticity of host 'xxx.xxx.xxx.xxx' can't be established.
RSA key fingerprint is 4c:83:...:7d:19.
Are you sure you want to continue connecting (yes/no)?
This happens when you login to a server using SSH for the first time on that server I believe. Normally if you answer yes then the key will be added to the known_hosts file and the next time that message should not appear.
It's a form of key protection agains man in the middel attack. You can read more about it here.

Yes, but the thing is I want to run rsync remotely on hundreds of servers, and do not want to log into each one and have to type yes.
I understand but you'd only need to do it the first time. Maybe there's a way to automate it with something like dssh. Another possibility is of course to generate key pairs and copy over the key to the destination server. If you do it the right way then the complete process of authentication takes place using the keys and you wouldn't even have to introduce a password.
