Are you referring to the user name and password?:
Before you set up Fling, you should have the following information:
● The FTP server. This can be in dotted IP form (e.g., 69.10.42.210) or in domain form (e.g., ftp.nchsoftware.com).
● Your username and password.
● The directory to load files to your web server. This could be something like /home/yourco/www/html or /var/www/html.
