Cerberus FTP Server is a multithreaded Windows FTP server designed to use little CPU and memory. Cerberus FTP Server requires a very modest system configuration.
Cerberus FTP Server comes with an easy to use interface and can be accessed from the system tray. The server is able to listen for connections on multiple interfaces (Multi-homed PCs), allow PASV connections, resume failed transfers, and offers an easy-to-use manager for controlling user access to files and file operations. Connection limit, timeout, and IP access can be controlled by the administrator as well as thread priority settings.
In addition, Cerberus FTP Server offers statistics on connections as well as logging capabilities.
Note: Free for personal, non-commercial use. If you want to use it for commercial use, you must buy the program from here.
