Part 2: Connect to shared server (VPS) using SSH

Generate key pair locally:

$ ssh-keygen

I chose the default. Some suggests not to type a password if you are the only person to have root access to the local machine.

Next I copied key to remote shared server:

$ ssh-copy-id root@IP_address_of_VPS

The shell should prompt you to enter the password for the username of the VPS. I mixed root with user passwords thus had issue login in.

Still on the local machine, I ran:

$ ssh root@IP_address_of_VPS 

The shell should prompted me to verify the fingerprint of the SSH key of the server.

The VPS provider I use sends the fingerprint via email when setting up the server. If you need to find out the SSHs key fingerprint: https//yctct.com/ssh-show-fingerprint

If the key matches, type yes.

You should see root@vps_username:~#

Security

Once I am sure the SSH is enabled, I disable log in via password and else by un-commenting the following line and setting them up to no in /etc/ssh/sshd_config.

PasswordAuthetification no
UsePam no

Make sure you use sudo vi to edit /etc/ssh/sshd_config.

When you are done, reload the SSH daemon:

systemctl reload sshd

I do self-funded research and I'm writing a book.

> What's the book about?

About technologies and agency.

Meaning, technologies can foster agency. No doubt. But I am also asking:

Can usage of technologies give us a sense of empowerment while in fact undermining our abilities?

I posted a summary of the prologue on the homepage: https://yctct.com/
