How to start sftp and add user name and password?

[macunkie]

So I'v successfully got Apache2 installed and Wordpress installed.
Wordpress is asking for updates and upon attempting to update it is asking for :
HostName:
Ftp UserName:
Ftp Password:

I've gogled pure-ftp and sftp which is supposed to be installed on Fedora 17. I just have no idea how to start it and set up a userame and password.

Thanks for any advice ,

Samuel
