Using SSH Keygen not able to connect to server on

问题:

I'm following below tutorial.

https://www.digitalocean.com/community/tutorials/how-to-set-up-ssh-keys--2

It's generated file on Windows 10 C:\Users\<user name>\.ssh

I'm using GIT to generate files.

 ~/Desktop
$ PermitRootLogin without-password
bash: PermitRootLogin: command not found

$ ssh [e-mail]
[e-mail]'s password:
Permission denied, please try again.

I have generated .ppk file using puttygen.exe.
Still not able to connect to server.

By doing ssh -Tv [e-mail]

It will give below response

If you do have

• your public key: C:\Users\<user name>\.ssh\id_rsa.pub
• your private key: C:\Users\<user name>\.ssh\id_rsa

Do copy your public key (see "How To Use SSH Keys with DigitalOcean Droplets")
