I hope you didn't think I meant to type "cyrus" as the password. Type the password for the user "cyrus" after you type "su cyrus". Remember that when you use "su" to become another user, it's as if you login as that particular user, so you have to supply the password for whatever user you are "su"-ing as at the "Password:" prompt.
