DNS & domain registration

• nameservers define your domain's current DNS provider
• by changing nameservers you change the site in which to manage your DNS records, examples:
  • you can change your nameservers to freedns1.registrar-servers.com and freedns2.registrar-servers.com to start using Namecheap's FreeDNS service to manage DNS records on Namecheap instead of on your current registrar (source)
  • you can change your nameservers to ns1.digitalocean.com., ns2.digitalocean.com. and ns3.digitalocean.com. to start using DigitalOcean to manage DNS records instead of using your current registrar (source)
• some registrars don't allow you to change nameservers or charge an extra fee for it
• for example, Cloudflare doesn't allow for custom nameservers unless the client

Digital Ocean

Enable password authentication in SSH

• usually, you just need to set PasswordAuthentication yes at /etc/ssh/sshd_config and restart service (systemctl restart sshd)
  • https://docs.digitalocean.com/support/i-lost-the-ssh-key-for-my-droplet/#enable-password-authentication
• however, Ubuntu have a Include /etc/ssh/sshd_config.d/*.conf at the beginning of said config and, because sshd applies the first config it finds, you must change the PasswordAuthentication directives in the files inside /etc/ssh/sshd_config.d/*.conf
