1) I have a number of machines where I often ssh from one to another. I just did that with a regular pair and got:
Warning: the RSA host key for 'triggerfish' differs from the key for the IP address '192.168.2.124'I GUESS but do not KNOW that the known_hosts[2] and [3] refer to the 2nd and 3rd or 3rd and 4th entries out of the 12 that exist. I do NOT want to be editing those all the time so does anyone know a way to avoid that?
Offending key for IP in /home/larry/.ssh/known_hosts:2
Matching host key in /home/larry/.ssh/known_hosts:3
Are you sure you want to continue connecting (yes/no)? yes
