Question from a newbie: can't login on proftpd

I have used this tutorial to install my server.
Now I want to login using FTP.
I use the ip-adres of my server + user=root +pass=pass of server-admin.
Connecting to server goes fine, but the password is incorrect.
The tutorial doesn't say anything about setting up a password.
My question is: how do I set up a user+password with access to all the directories and files?

I am sorry if this is a real simple question, but I am a noob and have no experience at all. [*SHAME*]

 

Nobody????
I have created a new user, but in both cases it keeps giving 530 responses.

 

In most default Proftpd configurations, root cannot use FTP for security reasons.

To add a user, see

Code:

man useradd

(add a user with the shell /bin/bash for now).
After you've created the user, you can create a password for him like this:

Code:

passwd username
