SSH noob here. I’m having trouble create a valid SSH configuration (in ~/.ssh/config) which allows multiple users to log in to the same remote host (a VPS on Digital Ocean, in this case).

A bit of background. I created a Droplet (VPS) on DO (Digital Ocean), and DO automatically applied the default public key I had already registered with them to the root user. This allows me to SSH in with no configuration on my end.

However, I added a second user (ron) on the Droplet and created an authorized_keys file for that user to allow me to SSH in. This requires me to create a config file on my machine in order to log in as both users (ron and root). Here is the file I created (The IP address given is just an example):

Host 161.00.100.100
        HostName 161.00.100.100
        User ron
        IdentityFile ~/.ssh/private_key_for_ron
        IdentitiesOnly yes

Host 161.00.100.100
        HostName 161.00.100.100
        User root
        IdentityFile ~/.ssh/private_key_for_root
        IdentitiesOnly yes

After creating this, I can only SSH in to the remote server as user ron and not root. In case it’s helpful, the remote server on DO is Ubuntu and my local machine is Debian.

Can someone tell me what I’m doing wrong?

Thanks!
