When access ssh for first time, prompt to add fingerprint to known hosts about backport HOT 6 CLOSED

@epixa That's a good point. I was not looking forward to supporting several authentication mechanisms.

from backport.

@sqren I recommend encouraging best practices (ssh) through this tool rather than supporting other use cases (passwords) just because they exist. You could always add the password stuff if there was enough demand for it.

Hi @liza-mae, thanks for making me aware of this. I just tried to delete my known_hosts file and was able to reproduce the issue, and was getting this error

The authenticity of host 'github.com (192.30.253.113)' can't be established.
RSA key fingerprint is <fingerprint>.

it should also output this part, and wait for user input (but it doesn't)

Are you sure you want to continue connecting (yes/no)?

I was not even considering this case. Is is because you have not before interacted with github over ssh? Do you normally use password authentication instead of ssh?
It occurs to me, that some users might not even use ssh - so apart from being able to setup ssh on first-time use, it should ask whether to use ssh or password, right?

@liza-mae were you able to solve your problem by adding github.com to you known hosts before running backport? ssh github.com should do the trick.

Hi @sqren , yes that did work for me. Thanks.

Good to hear!
