ssh-keygen I was able to generate a public-private key pair one Machine#1 and then I copied the public key to Machine#2 using
ssh-copy-id. On Machine#2, I noticed that there are 3 key-pairs already generated in the
/etc/ssh folder and I was wondering what are these for? Is the purpose of them to simply allow copying the private key and use it?
Can I grant access to Machine#1 w/o generating a key-pair by simply copying one of the private keys already present in the
/etc/ssh folder of Machine#2? If so how do I do it?
