If you recently purchased a new account with Avalon MIS, you receive access to your server space using cPanel. 

"cPanel is the industry leader for turning standalone servers into a fully automated point-and-click hosting platform. Tedious tasks are replaced by web interfaces and API-based calls. cPanel is designed with multiple levels of administration including admin, reseller, end user, and email-based interfaces. These multiple levels provide security, ease of use, and flexibility for everyone from the server administrator to the email account user."
