To connect to your site via FTP you can simply use your domain name as the hostname (without the www), along with the username and password you assigned when you created the account. 

To upload before your domain name has propagated, you can use the server name as the hostname, ie., "web5.onnetsecure.net," "win3.onnetsecure.net," etc. Important: In order to determine which server any given domain is on, click on the "FTP" icon in your end user CP and you will see it listed there. Note that you will need to replace your service domane with "onnetsecure.net" until your domain is fully propagated.

Please note that there is an 8 character limit for the ftp username. The ftp username is also show on the home page of your end user control panel for any given account. 

Don't upload your site to the root of your user directory! Instead, put it in the specific directory for the domain you are uploading to. Whenever you add a domain on the system, a corresponding directory is created for that domain name. i.e.:

 /mydomain.com

Contents of Your Home Directory

Your home directory contains several default subdirectories. Their number and names will differ depending on your plan, yet some of them are common for all plans. Here are some of the directories that are automatically created and may not be deleted:

• Directories that contain your sites. Each of your sites is put in a separate directory. The name of the directory is the same as your site's domain name. If you have more than one site, you will have several such directories. These are the directories where you will upload your .html files or any other files that you want to make accessible from the Internet. Each of these directories may contain their own /webalizer or /modlogan directories. Do not delete either of these directories!  
  
  
• The Logs directory. It contains directories for every site with transfer logs enabled. Each such directory contains its own set of log files that are required to write and read the data about all visits to your sites. Deleting the Logs directory will cause the loss of the web statistics accumulated in the course of your site operation. Click here for more on web statistics.
  
  
• The Virtual FTP directory. Its name is the dedicated IP address. This directory is created when you enable Virtual FTP Server and can be accessed by virtual FTP users to list and download its content. There are as many such directories as dedicated IP addresses. Deleting Virtual FTP directories will cause incorrect operation of Virtual FTP. However, you may harmlessly delete individual files in these directories. Click here for more on Virtual FTP.
  
  
• The subdomain directories. When you make a subdomain, a new directory is created with the subdomain name as the directory name. If you delete a subdomain directory, internet visitors will get the 404 "File not found" error when attempting to access the subdomain. 
  
• The ssl.conf directory. This directory stores SSL pairs for all encrypted sites. Deleting the ssl.conf directory will result in incorrect SSL operation.

Warning: Your root directory contains many default sub-directories that are used by the system. Don't delete ANY default directories in your root directory, as this will cause malfunctions in your account. As a rule of thumb, you may delete only directories and files you have uploaded yourself or that have been uploaded by any of your Virtual FTP and Anonymous FTP users.
