QUESTION :
I have two types of keys based on RSA and ED25519 keys.
however when I do
ssh -i ~/.ssh/id_ed25519 <server>
I get prompted to enter passphrase for RSA based key first then get asked for ED25519 key passphrase
Enter passphrase for key '~/.ssh/id_rsa':
Enter passphrase for key '~/.ssh/id_ed25519':
My both public keys are in authorized keys of the server.
What would be the reason for this
Also
~/.ssh/config
doesn’t any settings and is totally empty.
ANSWER :
The -i option of ssh specifies an extra private key to use.
To prevent ssh-agent from providing more identities, you can add the -o "IdentitiesOnly=yes" option to your command, but the default keys inside your ~/.ssh directory might still be tried.
The sure way to only use a specific key is to make an entry for the given host in the ~/.ssh/config file.
