Answer 1

The known_hosts file is required to connect to remote host wia Jenkins. When you try to ssh to remote server through command line, this prompt you to asking for adding this remote server to known_hosts. When you answer this prompt with 'Yes', the known_hosts file will be created automatically in ~/.ssh folder.

Then, you can connect to remote server from Jenkins UI directly.
