81.5 SSH Remote Host Authentication


When you use ssh to connect to a remote host for the first time you will be confronted with a message like:

The authenticity of host 'rosz (' can't be established. 
RSA key fingerprint is 99:1f:eb:c2:8f:cb7:33:23:1f:4c:e5:51:20:e9:85:5a. 
Are you sure you want to continue connecting (yes/no)? 

SSH does not know this host. Type yes to add the fingerprint of this host to ~/.ssh/known_hosts. Next time you connect to this remote host you should not get this message.
