i just signed up for linode hosting but i'm confused when i got to the log in via putty. i read through the guide that i have to verify fingerprint and that i should not click yes in the putty stuff, but i click yes without verifying it and when the window appeared i click to insert the root password but it wasn't showing. i'm completely newbie, i have never set up a linode hosting. i'm used to control panel on shared hosting. pls how can i proceed from here? thanks
