The authenticity of host 'bitbucket.org (104.192.143.3)' can't be established

Udi September 5, 2017

Hi Guys,

While following the Set up an SSH key tutorial, the command

ssh -T git@bitbucket.org [on section #8] is followed by the message:

The authenticity of host 'bitbucket.org (104.192.143.3)' can't be established.
RSA key fingerprint is ____________________________
Are you sure you want to continue connecting (yes/no)?

I would like to ask why does this happen and how it can be solved.

Thanks!

It is perfectly normal. When you connect for the first time, SSH prompts you to verify the authenticity of the server you are connecting to. It is just an added security measure to verify the server using the RSA key fingerprint.

You can type "yes" and proceed. This is a one time verification.

when I type "yes" and press ENTER, prompt disappear, but it appears every 5-10 minute repeatedly.
