unable to connect with SSH

Posted on September 1, 2018

I configured my droplet to set up for ssh by adding my public key into the droplet UI. Whenever I attempt to ssh in by pasting the private key I get an accessed denied error. I have not been able to log into my droplet so far. I am using a mac with terminal

Hello,

What I could suggest here is adding the -v argument which would give you some really useful debug information that you could use as a starting point. So the command would look something like this:

ssh -vvv your_user@your.server.ip.address

Hope that this helps! You could paste the output here as well if you wish. Regards, Bobby

Hello there,

You can check our article on How to Upload an SSH Public Key to an Existing Droplet

https://www.digitalocean.com/docs/droplets/how-to/add-ssh-keys/to-existing-droplet/

You can access the droplet from the DigitalOcean console and then temporary enable the PasswordAuthentication on your droplet and access the droplet with a password to upload the ssh-key.

If you haven’t created new pair of keys you’ll need to do that first.

You can enable PasswordAuthentication for your Droplet by modifying your /etc/ssh/sshd_config file. Once set to Yes restart the SSH service and connect via an SSH client for a more stable connection. You can then modify your ~/.ssh/authorized_keys file to add the appropriate public key.

This change can be made from the DigitalOcean’s console. If you’re having issues accessing the console you can then reach to our amazing support team that can help you further with this.

To enable the PasswordAuthentication follow these steps:

Login to the console on the DigitalOcean website.
Type sudo nano /etc/ssh/sshd_config
Change PasswordAuthentication from “no” to “yes” and save the file
Open a terminal on your computer and type ssh username@[hostname or IP address] or if on a Windows box use PuTTY for password login making sure authentication parameters aren’t pointing to a private key
Login with a password
Type sudo nano ~/.ssh/authorized_keys
Paste public key text here and save the file
Type sudo nano /etc/ssh/sshd_config
Change PasswordAuthentication from “yes” to “no” and save the file
Log out and attempt to log back in (if using PuTTY make sure you set up auth parameters to point to your private key)

You can then upload the key using this command:

ssh-copy-id -i ~/.ssh/mykey user@droplet

Hope that this helps! Regards, Alex
