You should now have Putty installed and linked to your VPS. Login to your VPS using Putty, the default username from your Vultr VPS is root and the password and ip are also listed in the server details section of Vultr. You're going to be doing a lot of copy-pasting in and out of Putty. If you are new to this, it's important to know that passwords in Linux do not display on screen for security. Also, in Putty, you can simply right-click to paste... VERY convenient, especially when running multiple nodes and using multiple Putty connections simultaneously.
