$ ssh-keygen -t rsa -C “username”
Generating public/private rsa key pair.
Enter file in which to save the key (/location/to/.ssh/id_rsa):/home/location/to/.ssh/authorized_keys
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /home/location/to/.ssh/authorized_keys.
Your public key has been saved in /home/location/to/.ssh/authorized_keys.pub.
Then upload the public key to ./ssh2/authorized_keys on your server. If you want us to test the private key, include that as well.
After the file is loaded onto the machine open a support ticket and let us know the file names for the public and private keys. We will take care of the rest.
