This article provides steps for connecting to a cloud server from a computer running Linux® or MacOS® X by using Secure Shell (SSH). It also discusses generating an SSH key and adding a public key to the server. SSH is a protocol through which you can access your cloud server and run shell commands. The private key is able to generate signatures. A signature created using your private key cannot be forged by anybody who does not have that key; but anybody who has your public key can verify that a particular signature is genuine. So you generate a key pair on your own computer, and you copy the public key to the server. SSH keys are a way to identify trusted computers, without involving passwords. The steps below will walk you through generating an SSH key and adding the public key to the server. Step 1: Check for SSH Keys First, check for existing SSH keys on your computer. Open Git Bash, Cygwin, or Terminal, etc.
I updated my private key and added the public key to the authorized_keys on my target hosts and it didn't work. I ran a few verbose connections to see that the key was being sent, but not accepted.
Turns out the old version of ssh on this server doesn't generate the public key from the private key, it reads the id_rsa.pub file to send the public key. Since this public key doesn't match what's in authorized_keys, I was denied.
The solution was to delete the public key. Alternatively, you can generate the public key with ssh-keygen.
I noticed that the ssh on my workstation doesn't read the id_rsa.pub file, so it must be an issue with the older ssh on the server (hosted server, I can't update it)

Log in with an SSH private key on Linux and macOS
This article demonstrates how to use a private key to log in to a Linux速server by using a private key with a Terminal session on macOS速. However,you can follow the same process to use a private key when using anyterminal software on Linux.
Note: For information about using Secure Shell (SSH) private keys on Microsoft速 Windows速 operating systems, see Logging in with an SSH Private Key on Windowsand Generate RSA keys with SSH by using PuTTYgen.
Prerequisites
To complete this process, you need the following software applications:
- SSH client software that is installed on your Linux or macOS operating system by default.
- Your favorite text editor. This example uses the vim text editor.
- Your private key. For more information about generating a key on Linux or macOS, see Connect to a server by using SSH on Linux or Mac OS X.
Log in with a private key
Using a text editor, create a file in which to store your private key. This example uses the file deployment_key.txt.
To edit the file in vim, type the following command:
After the editor starts, press i to turn on insert mode.
Paste your private key, such as the one in the following image, into the file.Be sure to include the BEGIN and END lines.
To save your changes, press Esc.
Type :wq to write the file and return to the command line.
Run the following command to change the file permissions to 600 to secure the key. You can also set them to 400.This step is required:
Use the key to log in to the SSH client as shown in the following example, which loads the key in file deployment_key.txt, and logs in as user demo to IP 192.237.248.66:
When you are prompted to confirm the connection, type yes and then press Enter.
If your SSH key requires a password, enter it when prompted to complete the connection.
