Our network provider wanted to provide us with some new client softwares related to better network connectivity and administration tools. The files are big and even due to security reasons not advisable to sent through emails.
The solution to this is either they ship CD's or we provide them with an access to our FTP site where they can upload and we can download straight away and its secure as well.
How it all works? We have a web server (meaning it can be accessed from around the world) and every web server has an ftp( file transfer protocol) site. To manage the ftp we have ftp secure server software. using this software we can configure he site and authenticate different users to access our web server as much as we want to. Every user is given a home drive on web server which they can access for uploads and downloads. So every time some files are to be exchanged customers can log into the ftp site using their provided username and password.
