Serv-U is a powerful, easy-to-use, award-winning FTP server created by Rob Beckers. An FTP server uses the FTP protocol to share files across the Internet. Serv-U is not only 100% compliant with the current FTP standard, but also includes numerous features unique to Serv-U that make it a perfect file sharing solution for virtually everyone. Flexible FTP server (or Daemon) for all 32-bit versions of MS-Windows (Win95, Win98, WinME, NT, Win2000, Win2003, XP). It turns any PC with a network connection into an FTP site on the Internet. Serv-U makes a vast array of features available to the user that ensures the administrator has full control over their FTP server.

Serv-U offers the following:

- A Windows standard, with over 50000 registered users!

- Multiple 'virtual' FTP servers can be set up on a single instance of Serv-U.

- Server can be administered remotely.

New in Serv-U™:

Windows User NT-SAM/Active Directory. Serv-U focuses on the needs of our Corporate customers by adding Windows User NT-SAM / Active Directory support. If you're supporting FTP transfers in a corporate environment you can now use Serv-U to support your users with little or no configuration changes. Simply install Serv-U, create a new Windows User domain, and Serv-U is supporting all of your Windows user's FTP needs.

ODBC Database Support. Serv-U now supports integration with ODBC databases. This addition makes it easy to import large user databases in to Serv-U while maintaining the server computer's current infrastructure for maintaining the user database and settings.

XCRC Support. Nothing's worse than successfully completing the download of a file from a server that doesn't work! It forces you to begin the arduous process of figuring out if the download was corrupted or if the source file has a problem. With XCRC command support, you can quickly verify that the file you downloaded/uploaded is identical to the source file.

Asymmetric Bandwidth Throttling. Internet connections are rarely symmetric in terms of speeds so why should a server assume they are? With Serv-U, you can now specify separate bandwidth throttling levels for upload and download speeds.

User Level SSL Control. Not every FTP user is created equal and no software knows that better than Serv-U! With the added ability to require an SSL connection for specific user accounts, you can ensure that "superusers" who connect to your server maintain a high level of security without forcing every other user to adapt as well.

Speed Enhancements. Serv-U contains a variety of performance enhancements that makes Serv-U faster than ever. We've tweaked and improved code that speeds up connections and improves various cached data elements.
