I have two droplets. One with Nginx where my webapp is running and one for MySQL. Both have a private IP address. I have installed both droplets and software. Now i’m securing the MySQL droplet. I only want to connect with SSH through my Nginx droplet.
I created a DSA key (private and public) with putty-keygen and added the public key in my DigitalOcean. When I created both droplets, I picked that public key. With Putty, I can connect to both droplets. The key is protected with a passphrase.
Then I uploaded my private key on my Nginx droplet in /home/agromedi/.ssh/id_rsa
When I login as the agromedi user and I want to connect to SSH. I use the private IP of the MySQL droplet and connect like this:
Then it asked for my passphrase. I enter it and then it asked it again and again and then I get “Permission denied (publickey)”. The rights on the file are 600 (I tried 400 also but nope). I renamed the file to id_dsa. Nothing worked. With the -vvv option, I get more info that the passphrase is wrong. But I use the same private key on Putty with the same passphrase… Or is the keyboard wrong in my console? Or maybe I’m doing something wrong?
