Configuring vps for first time

# OS: Ubuntu

## Basic Configuration
  -- login using ssh
     # ssh root@IP
  -- Update latest updates/security patches
  -- set timezone
     # timedatectl set-ntp true
     # dpkg-reconfigure tzdata
  -- Add new user - 
     $ adduser username
     Give sudo permission 
     $ adduser username  sudo 
  -- SSH using new user
      ssh username@IP

## Security 
  - create your ssh key
  - add your public key using secure copy (scp)
      $ scp ~/.ssh/ur_pub_file.pub username@IP:~/.ssh/authorized_keys
      OR
      $ ssh-copy-id username@IP
   
  - NOW, SSH using key instead of password
      $ ssh username@IP
  - OPTIONAL: Remove root login using password
      $ nano /etc/ssh/sshd_config
      Find PermitRootLogin and set no
      - Restart SSH
      $ sudo service ssh restart
