SSH Errors

SSH key is stored in .ssh folder on your home directory. To see if you have SSH key, run

cat .ssh/id_rsa.pub

If you don’t have one, generate SSH key with

ssh-keygen -t rsa -b 4096 -C "[email protected]"

This will create SSH public and private key in your home directory. The location will be

/home/USER/.ssh

Your private key will be

/home/USER/.ssh/id_rsa

This is PRIVATE, never ever share it with anyone.

Your public key will be stored at

/home/USER/.ssh/id_rsa.pub

It is public, it is OK to share with anyone. If someone need to grand you access to their server with out password, they need to add content of this file to file named ~/.ssh/authorized_keys.
