Problem with Key Authentication
Am trying to set up SSH key authentication with my new VPS.
When I use CyberDuck to log in to my VPS, the "fingerprint" is not matching the one that was created when my keys were created and the connection is failing. I am wondering if the problem is due to the fact that I ran ssh-keygen on my MacBook and then copied and pasted the Public Key into a webform in cPanel? While my host allows you to generate the key pair on the VPS, it creates a security issue in that I would then have to find a safe way to get my Private Key back to my MacBook. So, instead, I opted for the opposite approach and chose to create the key pair on my Mac - thus leaving the Private Key untouched on my Mac. Any idea what is going on? Rob |
You could try removing the entry for the VPS from your known_hosts file in your .ssh foider and try the connection again.
If you get any error messages then post the whole error message. |
Someone mentioned that I need to get the fingerprint off of my VPS...
That leaves me with more questions... 1.) What makes up a Fingerprint? Does it include things about the computer? Public/Private Keys? IP? My info? 2.) Does the Fingerprint every change? If so, why? 3.) How would I get the Fingerprint for my VPS? 4.) Why does ssh-keygen display a Fingerprint if that isn't the one I need to use? Thanks, Rob |
A fingerprint is a short, rapidly computable, hash of a piece of data where a strong cryptographic hash is not needed.
e.g. to identify a machine or ip address of a machine with a reasonable degree of probability. |

Thanks for the replies, but answers to my specific questions would be a better place to start. ;)
