Hi all,
I can have two ssh key from different computer, right now I have one ssh key on my droplet, but I need another one ssh from my other computer.
I try this.
cat .ssh/id_rsa.pub | ssh root@dropletipaddress "cat >> ~/.ssh/authorized_keys"
but doesn’t work, but I not have password from my droplet, only connect with ssh.
as I can fix it.
thanks in advance.
Hi!
What that command tries to do is take the contents of the file containing the public portion of your SSH key pair, ~/.ssh/id_rsa.pub and append it to the bottom of the file ~/.ssh/authorized_keys on your server.
So to add the new key, all you need to do is send the contents of ~/.ssh/id_rsa.pub to the computer that already has access to the server and then copy and paste it into the ~/.ssh/authorized_keys on the server.
If you are using Debian or Ubuntu and you have your public key on GitHub, you can use the ssh-import-id on the server to do this automatically. Run:
ssh-import-id gh:github_username
