So I have my home computer, and my server. I'm trying to login to my server with my private key.
On my server say I have the user serveruser
, to which I login from my home computer using
ssh -Y [email protected]
And at my home computer, I have the user homeuser
on my home computer.
So now, I want to login to the server using my private key. For that, I already have a key with passphrase in /home/homeuser/.ssh/
. So I took the public key (id_rsa.pub), and copied it to my server at /home/serveruser/.ssh/authorized_keys
.
Now I would like to login using that key, so I tried to login using
ssh -Y [email protected]
and it still asks me for the password, and not the passphrase.
I tried also logging in using
ssh -i /home/homeuser/.ssh/id_rsa -Y [email protected]
and I'm still being asked for the user password.
What did I do wrong? Please advise.
Thank you for any efforts.
EDIT: According to Mason Heller's recommendation, I executed ssh-add, but it still insists that I input the password for [email protected].

passed to it, to see whether it loads your private key and tries to offer it for authentication to the server. Pasting it here may offer other people more clues to answer your question.cat /home/homeuser/.ssh/id_rsa.pub

,cat /home/serveruser/.ssh/authorized_keys
.cat /home/homeuser/.ssh/id_rsa.pub >> authorized_keys
). (Obviously you have to copy the public key to the server first.) Now just having you execute those commands should have made you think whycat
didn't work ;-)
